Grid-Down Survival Master Guide
Long-term power, fuel, communications & food-supply breakdown · UK Edition 1.0 · Print & keep with your supplies
Most emergency advice assumes the lights come back on within a day or two. This guide is for the case where they don't — where a national blackout, a severe solar storm, a fuel crisis, a collapse of phone and internet networks or a breakdown in food deliveries lasts for weeks, and each failure makes the others worse. It covers what actually happens, hour by hour and week by week; what to store for a family of four; how to keep warm, fed, clean and safe at home in winter, summer or a storm; how to stay in touch when phones are dead; how to handle unrest; and how to decide whether to stay, move somewhere remote, or leave the country — and how.
⚠️ Important — Please Read First
This is an educational preparedness reference, not professional medical, legal, security or emergency-services advice. It cannot replace official instructions. In any emergency, follow the guidance of the emergency services, your local council and the government (broadcast on BBC radio and published at gov.uk) first.
Medicines, doses and diets: notes on medicines, insulin, infant feeding and gluten-free eating are general reference information. Speak to your GP, pharmacist or dietitian now, while services are working, about building a safe reserve for your own household's needs.
The law still applies. UK law on fuel storage, weapons, self-defence, trespass and theft does not stop in a crisis. Nothing in this guide suggests carrying weapons or using force beyond what the law allows. The safest way to win a confrontation is to avoid it.
Plan, practise, rotate. Figures for durations, quantities and distances are planning estimates. Test your kit, practise your plan (try one evening with the main fuse off), and rotate food, water, medicines and batteries before they expire.
The three rules of a grid-down event:
1. Act early. The first 24–48 hours, while shops, cash machines and fuel stations still have stock and the streets are calm, are worth more than everything that comes after. Most of the choices in this guide get harder or impossible by day 3–5.
2. Stay put unless staying is worse. Your home, your supplies and your neighbours are your strongest assets. Moving is dangerous and should be a decision, not a panic.
3. Stay together, stay quiet, stay warm. Groups survive; isolated people and people who advertise their supplies struggle. Cold kills faster than hunger.

⛓️ How a Long-Term Breakdown Unfolds
Modern Britain runs on a chain of systems that depend on each other. Electricity runs the water pumps, the fuel pumps, the phone masts, the card machines and the cold stores. Fuel moves the food. Phones and the internet coordinate everything. When one link breaks for more than a day or two, the others start to fail too — and that cascade, not the original cause, is what makes a long outage dangerous.
What to expect, and when
- Lights, heating, fridges, card machines, traffic lights, lifts and most broadband stop. Trains stop; some areas lose water pressure.
- Mobile signal fades within minutes to hours: Ofcom found only about 1 in 5 mast sites has an hour or more of battery backup, and about 1 in 20 has six hours.
- Digital (VoIP) landlines stop unless they have a battery unit. BBC radio and some transmitters keep going on generators.
- Most people assume it will be fixed by tonight. This is your best window to act.
- Shops that can open sell out of water, bread, batteries, candles, gas cartridges and fuel; queues and short tempers.
- Fuel stations can't pump without power; those that can are mobbed. In the September 2000 fuel protests, around 3,000 stations were dry within four days and supermarkets warned they would run out of food "within days".
- Freezers defrost (a full one stays frozen for about 48 hours). Homes cool by a few degrees a day in winter.
- Water companies switch to generators and must provide alternative supplies (bottled water, bowsers) within 24 hours, prioritising vulnerable customers.
- Shelves stay empty; cash runs out; generators run short of fuel; some water and sewage services fail.
- Hospitals, police and councils run emergency services from a few powered sites. Rest centres open.
- Older and vulnerable people are at serious risk from cold, missed medicines and isolation.
- Opportunistic crime rises, especially at night (see Security).
- If power is restored in stages, rationing and rolling cuts may continue for weeks. If the cause is physical damage (destroyed transformers, a prolonged fuel or supply-chain collapse), parts of the country may be affected for months.
- Communities that organised early stabilise; isolated households struggle. See The Long Haul.
🎯 The Five Triggers — and How Each One Differs
The guide covers five kinds of breakdown. They often arrive together, but each starts differently, gives different warning, and fails in a different order. Knowing which one you're facing tells you what will break next.
| Trigger | Typical causes | Warning | What fails first | What still works |
|---|---|---|---|---|
| ⚡ Long power outage | Grid failure, storm damage, cyber-attack, sabotage, energy shortage leading to rolling blackouts | None to days (rolling cuts are usually announced) | Lights, heating, phones, water pressure, payments | Mains gas (but not boilers), cars with fuel, battery radios |
| 🌞 Solar storm | Severe space weather: coronal mass ejection hitting Earth's magnetic field | About 15 hours to a few days for the main impact; severity known only ~30 minutes ahead | Parts of the grid, GPS, satellite links, HF radio, flights | Cars, phones and small electronics themselves |
| ⛽ Fuel crisis | Refinery or import disruption, blockades, driver shortage, war, panic buying | Usually days — news of shortages, queues | Fuel stations, deliveries, then food on shelves | Power, water, phones (at first) |
| 📶 Comms outage | Network failure, cyber-attack, cable cuts, power loss to masts and exchanges | None | Mobile, internet, card payments, online ordering, coordination | Broadcast radio, power, fuel |
| 🛒 Food supply failure | Any of the above; transport collapse; import disruption; crop failure; pandemics | Days to weeks | Fresh and chilled food, then everything on the shelves | Home stores, gardens, local producers |
⛽ Why fuel is the hidden weak point
- Almost all food reaches shops by diesel lorry, mostly from a few large distribution centres.
- In September 2021, a lorry-driver shortage plus panic buying left 50–90% of filling stations dry in parts of England within days, and the army was brought in to deliver fuel.
- In September 2000, blockades of refineries emptied around three-quarters of stations in five days and supermarkets began rationing.
- Lesson: keep your car tank at least half full at all times, and keep two weeks of food at home — fuel problems become food problems within a week.
🛒 How much food is in the system?
- Retailers run "just-in-time" supply: stock is delivered daily to match sales. Government estimates suggest the supply chain holds something like 10 days of non-fresh stock; fresh and chilled food much less.
- Panic buying empties shop shelves in a day or two even when the warehouses are full.
- The often-quoted warning that society is "nine meals from anarchy" (attributed to Lord Cameron of Dillington) makes the point: three days without food is when public order starts to strain.
🌞 Solar Storms & Geomagnetic Blackouts
A severe solar storm is one of the few events that could damage the grid itself, over a wide area, at the same moment. It is also widely misunderstood. It is not the same as a nuclear EMP: it doesn't fry phones and cars. It damages very long conductors — high-voltage power lines, the big transformers they connect to, pipelines and undersea cables — plus satellites, GPS and radio.
What happened before
- 1 September 1859 — Carrington Event: a huge flare was seen from England; about 17–18 hours later the storm hit. Auroras were seen as far south as the Caribbean; telegraph systems sparked, failed, or ran without batteries.
- 13 March 1989 — Quebec: the grid collapsed in about 90 seconds, leaving around 6 million people without power for about 9 hours; a large transformer was damaged in New Jersey.
- Estimates put a Carrington-scale storm at roughly once every 100–200 years. The UK government rates severe space weather as one of its higher-likelihood national risks (5–25% chance in five years).
What the UK expects (National Risk Register)
- Power disruption is expected to be regional, not national. Safety trips in cities recover within hours.
- Where high-voltage transformers are damaged — especially in remote and coastal areas — recovery could take several months. Replacing one takes around 8–16 weeks even when a spare exists.
- GPS and satellite navigation disrupted for days; satellite communications and HF radio disrupted; flights grounded or rerouted, with schedules taking weeks to recover.
- Mobile networks may need backup generators "for a sustained period" in some areas.
Use the warning: the 15-hour window
The Met Office Space Weather Operations Centre (MOSWOC) watches the Sun 24 hours a day and issues forecasts and alerts. If the news reports a severe or extreme geomagnetic storm warning, treat it like an amber weather warning and spend the hours before arrival doing the first 72 hours checklist early:
- Fill water containers and the bath; charge every battery, power bank and phone.
- Fill the car's fuel tank; withdraw some cash.
- Buy any missing medicines, baby supplies and a few days' extra food — quietly, before the rush.
- Download offline maps and print anything you need; tell family your meeting plan.
- Unplug sensitive electronics from the mains during the storm (protects against surges if the grid trips).
- If flying in the next 48 hours, expect disruption; if abroad, consider heading home early.
⏱️ The First 72 Hours: Action Checklist
- Fill water containers, the bath, buckets and pans while there's still pressure. Then fill more. (Taller buildings and hilltop homes lose pressure first.)
- Find torches, radio and batteries; switch the radio to BBC local radio or Radio 4 / Radio 5 Live for official information.
- Switch off and unplug appliances (prevents a surge when power returns); leave one light switched on so you'll know.
- Keep fridge and freezer doors shut.
- Check on vulnerable neighbours and family. Agree when you'll next check.
- Send one short text to family with your plan (texts often get through when calls don't), then save your phone battery: low-power mode, flight mode between checks.
- Fuel: fill the car if you can do so safely; don't queue for hours.
- Cash: take out cash (small notes) if any machine is working.
- Medicines: collect any prescriptions due; buy painkillers, rehydration salts, children's medicines.
- Top up: water, food you're short of, gas cartridges, batteries, baby supplies, pet food, toilet roll. Buy calmly and moderately — don't contribute to the stampede.
- Charge everything you can wherever power exists (car charger while driving, work, a café with a generator).
- Bring everyone home. Agree your family plan if phones fail.
- Winter Set up the warm room before the house gets cold (see Heat). Fit CO alarms.
- Eat from the fridge first, then the freezer. Move food that needs cooling somewhere cold.
- Set up the toilet plan in case water fails (see Sanitation).
- Inventory food and water; work out how many days you have; start gentle rationing.
- Talk to neighbours: who has what, who needs help, a meeting point, a watch rota (see Community).
- Write down the radio news with the time.
- Review: is it getting better or worse? Use the Stay, Move or Leave flowchart.
- If you plan to move to family or a retreat, this is the last good window while fuel and roads last.
- If staying: secure the house quietly, reduce light and noise at night, and settle into a routine.
- If water has stopped: start treating stored water, find the nearest bottled water or bowser point, and look for other sources (see Water).
🧭 Stay, Move or Leave: Making the Big Decision
The most important decision in a long breakdown is whether to stay where you are, move to somewhere better within the UK, or try to leave the country. Panic pushes people to run; evidence from real disasters says that for most households, staying at home with supplies and neighbours is safer than moving — until specific conditions make home worse than the road. Decide your conditions in advance, so you act on facts, not fear.
Staying vs going: the honest trade-offs
| Factor | Staying home | Moving |
|---|---|---|
| Supplies | All your stash, tools and clothes | Only what you can carry (10–15 kg each) |
| Shelter | Walls, roof, beds, a room you can heat | Uncertain — exposure is the biggest killer on the move, especially in winter |
| People | Neighbours who know you; a support network | You're a stranger everywhere; locals may be wary or hostile |
| Risk on the way | None | Injury, blisters, weather, robbery, getting lost, separation |
| When it wins | Most of the time, for most households | When home has no heat or water, is unsafe, and you have somewhere better to go |
If you're going to go, go early
🏙️ City, Suburb or Countryside: What Changes
Where you live shapes almost every decision. Cities have more people, more help and more danger; the countryside has more space and resources but less help and longer outages. Read the column that fits you — and the other columns, in case you have to move.
| Issue | City flats & terraces | Suburb / town | Rural / remote |
|---|---|---|---|
| Water | Mains pressure fails first in tower blocks (pumped). Few natural sources; rivers and canals heavily polluted. | Mains lasts a little longer. Rain butts, garden ponds, some streams. | Private supplies may need electric pumps. Springs, streams, wells — still treat it. |
| Heat | Flats keep heat well (neighbours above and below) but few have fireplaces. | Mix: some wood burners and chimneys. Draughty older houses cool fast. | More wood burners, fuel and wood available; homes often older and colder. |
| Food | Small storage space; shops empty in a day; no growing space. | Room for a stash; gardens and allotments. | Space, land, farms nearby — but shops are far and empty fast. |
| Sanitation | Biggest problem: high-rise toilets fail without pumped water; nowhere to bury waste. | Gardens allow burying and composting. | Easiest — but septic tanks and pumps may fail. |
| Security | Highest risk of unrest and looting, but also most police and help nearby. | Moderate; streets can organise effectively. | Low crowd risk; isolated homes are vulnerable and help is far away. |
| Help & information | Rest centres, aid points and news arrive first. | Usually reached within days. | Reached last; outages last longest. |
| Moving | Leaving on foot means crowded routes; plan early or stay. | Bikes and side roads work well. | You may be the place people move to. |
| Key actions | Store water in the flat (bath + containers); bucket toilet kit; know your block's neighbours; plan an early exit route. | Organise the street; store a large stash; set up rain collection; grow food. | Store fuel and wood; hand pump or water source plan; link up with neighbours and farms; plan for longer outages. |
City High-rise flats
- Lifts stop: older and disabled residents can be trapped upstairs. Know who they are.
- Upper floors lose water first. Fill containers immediately.
- Stairwells are dark: put glow sticks or battery lights on landings.
- Communal rubbish chutes will overflow — agree a collection point.
🌊 Coastal vs inland
- Coastal: fishing and sea access; a possible (risky) route out by boat; but storms, tidal flooding and, if people try to leave by sea, crowds at harbours.
- Inland: sheltered, often better for growing; far from ports; more reliant on roads and on rivers and reservoirs for water.
- See Leaving the UK for routes by sea.
💧 Water: Storing, Finding & Making It Safe
You can live for weeks without food but only a few days without water. Mains water depends on electricity for pumping and treatment; companies have backup generators, but these need fuel and not every site has one. Water companies must provide an alternative supply — bottled water and bowsers — within 24 hours, prioritising vulnerable customers, but in a widespread emergency the queue may be long and the walk far.
Government advice (prepare.campaign.gov.uk) gives 2.5–3 L per person per day as the survival minimum and 10 L as comfortable. Plan more for hot weather, breastfeeding, illness, heavy work and pets.
Where water hides in your home
| Source | Typical amount | Use |
|---|---|---|
| Stored bottled water | Whatever you've stored | Drinking. Rotate yearly (follow the date). |
| Bath (filled at the start) | 150–200 L | Washing and flushing; drinking only after treatment — or use a bath water bladder to keep it clean. |
| Hot-water cylinder (if you have one) | 100–200 L | Drain from the tap at the bottom (turn off the heater first). Usually drinkable after boiling. |
| Cold-water tank in the loft | 50–200 L | Washing; treat before drinking (can contain debris). |
| Toilet cisterns (not the bowl) | 6–9 L each | Washing/flushing; treat before drinking. Not if it contains blue cleaning blocks. |
| Pipes | a few litres | Open the highest tap, then drain from the lowest. |
| Tinned fruit/veg liquid, ice cubes | small | Drink it — don't pour it away. |
Water from outside
Better sources
- Rainwater from a clean roof via a gutter into a clean container (let the first few minutes wash the roof).
- Springs, fast-flowing streams upstream of houses and farms.
- Official bowsers and bottled water stations (listen to local radio).
Poor or dangerous sources
- Rivers and canals in towns (sewage overflows, chemicals, rats).
- Flood water — always contaminated.
- Water near farmland, roads, industrial sites or after heavy rain (run-off).
- Swimming pools and hot tubs (chemicals) — washing only.
- Radiators and central-heating systems — never drink (chemical inhibitors).
Making water safe to drink
Treat all water that isn't sealed bottled water or your own stored tap water. If it's cloudy, first let it settle, then pour it through a clean cloth or coffee filter.
| Method | How | Kills / removes |
|---|---|---|
| Boiling (best) | Bring to a full rolling boil, let it cool, keep covered. Store boiled water in a clean, covered container and use within 24 hours (in a cool place). | Bacteria, viruses, parasites. Not chemicals. |
| Purification tablets | Follow the pack exactly (usually 1 tablet per 1 L, wait 30 minutes; longer if cold). | Bacteria, viruses; chlorine dioxide tablets also kill most parasites. |
| Filters | Hollow-fibre or ceramic filters (0.1–0.2 micron) on a squeeze bottle, straw or gravity bag. | Bacteria and parasites. Most don't remove viruses — boil or add a tablet as well for town water. |
| Unscented bleach (last resort) | There is no official UK dose. US guidance (CDC): 2 drops per litre of plain, unscented bleach containing about 5–6% sodium hypochlorite (8 drops per US gallon); double it if the water is cloudy or very cold; stir and wait 30 minutes. It should smell slightly of chlorine — if not, repeat and wait 15 minutes more. Only use plain bleach with no detergent, thickener or fragrance (most "thick" bleaches are unsuitable); check the strength on the label. | Bacteria and viruses. Less effective on some parasites. |
| Sunlight (SODIS) | Clear plastic bottles of clear water in full sun for 6 hours (2 days if cloudy). | Bacteria and viruses. Slow, weather-dependent — a summer backup. |
🥫 Food: The Home Stash for a Family of Four
UK supermarkets run on "just-in-time" deliveries: stock arrives daily to match sales, and estimates suggest the whole supply chain holds something like 10 days of non-fresh food (much less fresh and chilled). Panic buying empties the shelves within a day or two of a crisis being announced. Whatever food you have at home on day one is very likely all the food you will have for the first weeks. The goal is simple: enough calories, eaten in the right order, stored in a way you'll actually rotate.
How much does each person need?
| Person | Normal daily need | Crisis minimum (light activity) |
|---|---|---|
| Adult man | 2,500 kcal | 2,000 kcal |
| Adult woman | 2,000 kcal | 1,800 kcal |
| Child 4–8 | 1,400–1,600 kcal | full need |
| Child 9–13 | 1,800–2,200 kcal | full need |
| Teenager | 2,200–3,000 kcal | full need |
| Pregnant / breastfeeding | +200 / +500 kcal | full need |
| Heavy work in the cold (wood, water, walking) | add 500–1,000 kcal | |
The stash: quantities for a family of four
Quantities give roughly 2 weeks (≈ 140,000 kcal) and 3 months (≈ 680,000 kcal), with a little margin. Swap items for your family's tastes — but keep the calories. Items marked GF have a gluten-free swap in the next section.
| Food | 2 weeks | 3 months | Notes |
|---|---|---|---|
| Rice (white, keeps longest) | 5 kg | 25 kg | Naturally gluten-free. Brown rice goes rancid within a year. |
| Pasta / noodles GF | 4 kg | 15 kg | Quick-cooking, filling. |
| Porridge oats GF | 3 kg | 12 kg | Breakfast staple; can be eaten soaked cold. |
| Dried lentils, split peas, beans | 1 kg | 10 kg | Cheap protein; red lentils cook in 15 min without soaking. |
| Instant mash / potato flakes | 1 kg | 5 kg | Needs only hot water. Check labels for gluten. |
| Tinned beans, chickpeas, lentils | 14 tins | 60 tins | Ready to eat cold or hot. |
| Tinned meat & fish (tuna, salmon, sardines, mackerel, corned beef, chicken) | 14 tins | 80 tins | Protein and fat. Oily fish give vitamin D — important in a dark winter. |
| Tinned soups, stews, curries GF | 14 tins | 60 tins | Many contain wheat flour — check. |
| Tinned vegetables & tomatoes | 14 tins | 80 tins | Vitamins and variety. |
| Tinned fruit (in juice), dried fruit | 14 tins + 1 kg | 60 tins + 5 kg | Vitamin C, morale. |
| Peanut / nut butter | 2 kg | 8 kg | Very calorie-dense. Check for nut allergies. |
| Nuts, seeds, trail mix | 2 kg | 8 kg | No-cook energy. Rotate — oils go rancid in 6–12 months. |
| Cooking oil (olive/rapeseed) | 2 L | 10 L | The most calorie-dense food there is: ~8,000 kcal per litre. |
| UHT / powdered milk | 12 L UHT | 6 kg powder | Powdered milk lasts much longer than UHT. |
| Crackers, oatcakes, crispbreads GF | 2 kg | 8 kg | Bread replacement. |
| Flour + yeast/baking powder GF | — | 10 kg | For flatbreads in a pan; needs fuel and skill. |
| Sugar, honey, jam | 1 kg | 6 kg | Honey never spoils. |
| Chocolate, biscuits, cereal bars | 2 kg | 8 kg | Morale is a survival need. |
| Salt, stock cubes, spices, tea, coffee GF | basics | 2 kg salt + plenty | Salt also preserves food. Many stock cubes contain wheat. |
| Multivitamins (adult + child) | 1 pack each | 3 packs each | Covers gaps in a tinned diet. |
📦 Store it well
- Cool, dark, dry, off the floor. Not a damp garage or hot loft.
- Dry goods in airtight food-grade buckets or containers — mice and moisture are the enemy.
- Mark the purchase date on everything; put new stock at the back.
- Most tins last 2–5 years past purchase; best-before dates are about quality, use-by dates are about safety.
- Have two manual tin openers.
🍳 Eat in this order
- Day 1–2: the fridge — milk, meat, leftovers.
- Days 2–4: the freezer, while it stays frozen. Keep the door shut; a full freezer stays frozen longer. Cook and share defrosting meat with neighbours rather than waste it.
- Week 1: fresh fruit, vegetables, bread, eggs.
- Then: tins, dry goods — rationed.
- Winter An unheated room, garage or a shaded cool box outside works as a fridge.
🌾 Gluten-Free, Allergies & Special Diets
In an emergency, shops lose their specialist ranges first and food parcels rarely cater for allergies. If anyone in your household is coeliac, allergic or on a medical diet, their stash must be planned separately — and kept separate.
Gluten-free Coeliac disease and gluten intolerance
- Rice (all types), rice noodles, rice cakes
- Potatoes, instant mash (check label), potato flakes
- Maize: polenta, cornmeal, corn tortillas, popcorn
- Quinoa, buckwheat, millet, sorghum, amaranth
- Dried and tinned beans, lentils, chickpeas, split peas
- Plain tinned fish, meat, vegetables and fruit
- Nuts, seeds, nut butters, dried fruit
- Oils, honey, sugar, jam, plain chocolate (check)
- Plain UHT milk, powdered milk, hard cheese
- Certified gluten-free oats, pasta, crackers, flour, breakfast cereals and bars
⚠️ Hidden gluten in "emergency" foods
- Stock cubes and gravy granules — most contain wheat; buy GF versions.
- Soy sauce — usually wheat-based; use tamari labelled GF.
- Tinned soups, stews, curries, baked beans in sauce, meatballs — often thickened with wheat flour.
- Sausages, burgers, corned beef products, ready meals.
- Breakfast cereals — many contain barley malt extract.
- Ordinary oats — contaminated with wheat during growing and milling; only oats labelled gluten-free are suitable.
- Couscous, bulgur, semolina, spelt, barley, rye — not gluten-free.
- Military/camping ration packs — check every pack.
- Read every label for wheat, barley, rye and oats (allergens are in bold in UK ingredients lists). "May contain" warnings matter to coeliacs.
- Keep GF food separate, clearly labelled, in its own sealed box — in a crisis, well-meaning people share pans and spoons. Use separate pans, utensils and a separate tin opener if you can.
- Gluten-free bread doesn't store; plan on rice cakes, GF crackers, potatoes and polenta instead. GF flour + baking powder makes pan flatbreads.
- A coeliac who is accidentally "glutened" may have diarrhoea and vomiting for days — dangerous when water is short. Carry rehydration salts.
- Coeliacs should carry a card stating their condition in their grab bag.
Other allergies and medical diets
| Need | Plan |
|---|---|
| Severe allergy (nuts, milk, egg, fish, sesame…) | At least two in-date adrenaline auto-injectors per person (ask your GP), antihistamines, a written allergy plan. Keep the allergen out of the shared stash, or clearly separate it. Peanut butter, a classic emergency food, is a risk in shared shelters. |
| Diabetes | Store fast sugar (glucose tablets, juice cartons) for hypos and slow carbohydrates (oats, beans, lentils). Keep spare testing strips, lancets and batteries. See Health for insulin storage. |
| Lactose intolerance / dairy-free | Long-life oat, soya or rice milk (check GF if needed); calcium from tinned sardines and salmon (with bones), fortified foods. |
| Vegetarian / vegan | Beans, lentils, peas, nuts, seeds, soya products, nut butters. Add a vitamin B12 supplement for vegans. |
| Kidney, heart or other medical diets | Ask your dietitian or GP now for a crisis version of the diet; many tinned foods are very high in salt — rinse tinned vegetables and beans. |
| Babies and toddlers | Formula (ready-to-feed cartons as backup), baby food pouches and jars, see Vulnerable people. |
🔥 Cooking & Fuel Without Mains Power
Hot food and drinks keep people warm, make dry stores edible and lift morale. You need a way to cook that doesn't depend on mains electricity — and enough fuel for weeks, not days.
| Method | Indoors? | Fuel to store (family of 4, 2 weeks) | Notes |
|---|---|---|---|
| Gas hob on mains gas | Yes (as normal) | — | Usually keeps working in a power cut — light with a match if the igniter is electric. Ovens and hobs with electronic flame-failure controls may not. Gas supply may fail later if the network loses pressure. |
| Butane/propane camping stove (cartridge) | Ventilated room only, with CO alarm | ~14–20 × 220 g cartridges (one hot meal + drinks a day) | Simple and reliable. Butane works poorly below about 5°C — use propane/butane mix or keep cartridges warm. |
| Two-burner camping stove on a propane bottle | Outdoors / porch | One 13 kg propane bottle lasts weeks | Propane works in freezing weather. Store bottles outside, upright, shaded. |
| Wood burner / multi-fuel stove with hotplate | Yes | Seasoned logs: 1–2 m³ | Heats, cooks and boils water at once. Only burn dry wood (under 20% moisture). |
| Rocket stove / Kelly kettle | Outdoors | Twigs, sticks, cardboard | Boils water fast on scraps. Excellent long-term fuel independence. |
| BBQ / charcoal / disposable BBQ | NEVER | — | Gives off deadly carbon monoxide for hours, even once it looks out. Never bring one into a house, tent, caravan or garage. |
♨️ Save fuel
- Haybox / thermal cooking: bring rice, porridge, lentils or stews to the boil for 5 minutes, then wrap the lidded pot in blankets or a sleeping bag (or put it in an insulated box) for 1–3 hours. It finishes cooking on its own with no more fuel.
- Soak dried beans and lentils overnight; choose quick-cooking rice, couscous (not GF), instant oats and noodles.
- Cook once a day and fill vacuum flasks with the rest of the boiled water for drinks.
- Always use a lid. Cook for the whole street together if you can.
🥫 No-cook food
- Most tinned food is already cooked and can be eaten cold: beans, meat, fish, soup, rice pudding, fruit.
- Peanut butter, crackers or rice cakes, nuts, dried fruit, cereal bars, UHT milk.
- Keep 3–5 days of no-cook food so a fuel failure never means no food.
❄️ Heat: Surviving a Winter Grid-Down
In a British winter, cold is the most immediate killer in a long power cut. Almost every modern home loses its heating when the electricity goes — including homes with gas central heating, because the boiler's pump, fan, controls and ignition all need power. An unheated, well-insulated house typically cools by a few degrees a day; a poorly insulated one can be close to outdoor temperature within 2–3 days. Plan to keep people warm, not the whole house.
The warm-room plan
- Pick one room: small, south-facing if possible, few outside walls and windows, ideally with a fireplace or wood burner. Upstairs rooms stay warmer (heat rises); avoid rooms over a garage.
- Close it in: shut doors to the rest of the house, hang blankets or duvets over doorways and windows, cover windows with bubble wrap, cardboard or foil-backed insulation, use draught excluders. Thick curtains closed at dusk, open on sunny days.
- Insulate the floor: rugs, camping mats, cardboard. You lose a lot of heat to cold floors.
- Everyone in together: four people give off roughly as much heat as a small heater (about 100 W each at rest). Sleep in the same room.
- Build a "room in a room": a tent pitched indoors, or a blanket den over a table, with everyone's sleeping bags inside, stays several degrees warmer than the room.
- Ventilate briefly twice a day, especially with any flame or stove in use, to stop CO and condensation building up.
🧥 Dress for it — indoors
- Layers: thermal base layer (wool or synthetic), fleece, insulated jacket. Avoid cotton next to the skin.
- Hat, scarf and fingerless gloves indoors. Warm socks and slippers or boots.
- Change out of damp clothes immediately — wet clothing removes heat 20+ times faster.
🛏️ Sleep warm
- Good sleeping bags (rated to −5°C or lower) inside duvets are the single best purchase for a winter outage.
- Insulate underneath: mats or folded blankets — more matters below than above.
- Hot-water bottles (filled from a kettle on the stove) and a hot drink before bed. Never use hot-water bottles for babies.
- Eat a fatty snack before sleep — your body burns it for heat overnight.
🔥 Safe heat sources
- Wood burner or open fire with a swept chimney — the best option. Store at least a few weeks of seasoned wood, dry and under cover.
- Indoor-rated portable gas heater (cabinet heater, butane): only with ventilation and a CO alarm, never while sleeping.
- Paraffin heater: same rules; store paraffin safely outside.
- Hot food and drinks, and exercise (a brisk 10 minutes), warm you from inside.
Never use for heat:
- Gas cooker rings or oven left on to heat a room.
- BBQs, charcoal, patio heaters or camping stoves in an enclosed room.
- Generators anywhere inside or near the house.
- Burning painted or treated wood, plastics or furniture indoors (toxic fumes).
Protect the house too
- Frozen pipes: if the house will drop below freezing for long, turn off the water at the stopcock and drain the system (open the lowest taps, flush toilets) — once you have filled your containers. Burst pipes cause floods when power and heat return.
- Gather all food that needs cool storage in the coldest room or a cool box outside in a shaded, animal-proof spot.
Hypothermia: spot it early
| Stage | Signs | Action |
|---|---|---|
| Mild | Shivering, cold pale skin, tiredness, clumsy hands, "the umbles" (mumbling, fumbling, grumbling) | Get to the warm room, remove wet clothes, dry layers, wrap in blankets including the head; warm (not hot) non-alcoholic drinks and sugary food if fully awake; share body warmth. |
| Moderate to severe | Shivering stops, confusion, slurred speech, slow breathing, drowsiness, blue lips | Emergency: handle gently, keep horizontal, warm the body core (chest, armpits, groin) first with blankets and body heat — not arms and legs. Don't use a hot bath, hot-water bottle or heat lamp, and don't rub limbs. Get medical help by any means (999). If not breathing, start CPR. |
Older people and babies can become hypothermic without shivering. Check them by feeling the skin of the chest or tummy, not hands.
☀️ Summer & Heatwaves Without Power
A summer outage is easier to live through than a winter one, but brings its own dangers: food spoils in hours, water needs double, flies and disease spread faster, and in a heatwave, older people, babies and the sick can overheat in homes that can't be cooled. UK homes — especially top-floor flats and loft rooms — trap heat.
🏠 Keep the house cool
- Close curtains and blinds on sun-facing windows by mid-morning; open windows at night and early morning for through-draughts.
- Live in the coolest room — usually downstairs and north-facing.
- Hang damp sheets in doorways or windows for evaporative cooling (only where air moves).
- Cook outdoors or at dawn; don't add heat indoors.
🧍 Keep people cool
- Drink regularly before you feel thirsty — plan 4–6 litres per person per day in hot weather, more if working.
- Cool showers or strip washes; damp cloths on the neck, wrists and feet; a spray bottle.
- Avoid the sun from 11am to 3pm; loose, light-coloured clothes; hats.
- Battery or USB fans help — and use little power.
Heat illness
| Condition | Signs | Action |
|---|---|---|
| Heat exhaustion | Headache, dizziness, nausea, heavy sweating, cramps, fast pulse, very thirsty, pale clammy skin | Move to a cool place, lie down with feet raised, drink water or rehydration solution, cool the skin. Should improve within 30 minutes. |
| Heatstroke | Hot skin (may be dry), confusion, fits, collapse, not responding, temperature 40°C+ | Life-threatening: get help by any means. Cool urgently — wet the skin and fan, cool packs to armpits and neck. Put in the recovery position if unresponsive. |
Also in summer: water treatment matters more (warm water grows bacteria faster); keep flies away from food and toilets (cover everything, use fly screens or netting); watch for wildfire risk in dry spells — never light fires in the open in dry weather, and keep a bucket of water and a spade by any outdoor stove.
🌪️ Storms, Flooding & Bad Weather on Top
Many UK power cuts are caused by storms, and a storm can strike during a longer outage. Wind brings down trees, lines and roof tiles; heavy rain floods roads and homes; snow and ice cut off villages. Combine those with no power and no phones, and small injuries become emergencies.
Before the storm hits
- Listen for Met Office warnings on the radio (amber and red mean act now).
- Bring in or tie down anything that could blow away: bins, garden furniture, trampolines, solar panels.
- Fill every container with water; charge everything; refuel the car if possible.
- Park away from trees; know where your stopcock, gas valve and fuse box are.
- Move valuables, supplies and medicines upstairs if flooding is possible.
During the storm
- Stay indoors, away from windows. Shelter in an inside room on the lower floor (or upper floor if flood risk).
- Do not go outside to check damage or move cars until it has passed.
- Do not walk or drive through flood water: 15 cm of moving water can knock you off your feet, 30 cm can float a car, and flood water hides open drains and is contaminated with sewage.
After the storm
- Treat every fallen line as live. Stay at least 10 metres away and keep others away; report it (105 when phones work).
- Check for gas leaks (smell) — if you smell gas, don't use switches or flames, open windows, leave, and turn off at the meter if safe.
- Check neighbours, especially older people.
- Photograph damage; make temporary repairs with tarps and battens to keep the weather out.
If your home floods
- Turn off electricity at the fuse box only if you can reach it without standing in water.
- Move people and pets upstairs with supplies, water, torch, radio, phone and warm clothes.
- Assume all flood water is contaminated: gloves, boots, wash hands, throw away any food it touched.
🔋 Light & Power: Batteries, Solar & Generators
You don't need to power a house — you need to power a few small, vital things: light, a radio, phones, and perhaps a medical device. Small batteries and a modest solar panel do this quietly and safely for weeks. Plan your power the way you plan food: by daily need.
What things actually use
| Device | Typical use per day | Notes |
|---|---|---|
| LED head torch / lantern (3–5 hours) | 1–5 Wh | AA/AAA or USB-rechargeable. The best value in the whole stash. |
| Smartphone (one full charge) | 12–20 Wh | Flight mode + low-power mode makes a charge last 2–4 days when there's no signal. |
| Radio (FM/DAB, several hours) | 1–3 Wh | Batteries last weeks in most portable radios. |
| Laptop (2 hours) | 60–100 Wh | Use sparingly — documents and maps are better printed. |
| CPAP machine (one night) | 40–100+ Wh | Without heated humidifier uses far less. Ask your supplier about a battery. |
| Fridge / freezer | 500–1,500 Wh | Too much for small systems. Use the "cold room" methods in Food instead. |
| Electric heater (1 hour) | 2,000–3,000 Wh | Impossible to run off batteries or solar. Heat people, not rooms — see Heat. |
🔋 Batteries & power banks
- 2–3 power banks of 10,000–20,000 mAh (≈ 37–74 Wh each) keep a family's phones going for a week or more.
- A portable power station (300–1,000 Wh, ideally LiFePO4 chemistry) runs lights, phones, radio and a laptop for days and can be recharged by solar. LiFePO4 is safer and lasts many more cycles than ordinary lithium.
- Stock AA and AAA batteries — lithium AAs last 10–20 years in storage and work in the cold. Standardise devices on one battery size if you can.
- Keep power banks 50–80% charged and top up every 3 months; check the date on stored batteries.
☀️ Solar
- A folding 60–100 W panel can recharge phones and power banks even on a cloudy UK day — expect only 10–25% of the rated output in winter or under cloud.
- UK winter daylight is short (7–8 hours in December in the south, under 7 in Scotland), so in winter solar is a top-up, not a supply.
- Point the panel south, tilt it steeply in winter, keep it clean, and keep it out of sight — a panel on display is a sign of power.
- A geomagnetic storm does not damage small solar panels, batteries or phones.
Generators: useful, dangerous, and noisy
☠️ Carbon monoxide kills
A petrol generator produces as much carbon monoxide as hundreds of cars idling. Never run one indoors, in a garage, shed, porch, cellar or near open windows or vents — not even "just for a minute" with the door open. Place it outdoors, at least 6 metres (20 ft) from doors, windows and vents, with the exhaust pointing away. Fit battery CO alarms in every sleeping area and every room with a flame. Symptoms — headache, dizziness, nausea, tiredness, confusion — are easily mistaken for flu; if several people feel unwell at once, get everyone into fresh air immediately.
- Connect appliances with heavy-duty extension leads. Never plug a generator into a house socket ("back-feeding") — it can electrocute engineers working on the lines and start fires. A proper changeover switch must be fitted by an electrician.
- Let it cool before refuelling; store fuel away from the house (see fuel storage law).
- Noise and fuel make a generator a security risk in a long outage. Run it for short periods to cool the freezer, charge batteries and pump water, then switch off.
- A small inverter generator (1–2 kW) is quieter and far more economical than a large site generator.
Lighting without fire risk
Candles & oil lamps
Fires cause many deaths in long power cuts. If you use candles: in a holder on a non-flammable surface, away from curtains, out of reach of children and pets, never left unattended, never to sleep by. Paraffin lamps and heaters need ventilation and a CO alarm.
🚽 Sanitation, Hygiene & Disease Prevention
In long emergencies, more people are made ill by dirty water, poor hygiene and human waste than by violence or hunger. Diarrhoea and vomiting spread fast through families and streets, and without clean water and medical care they can kill — especially children and older people. Good sanitation is a life-saving skill, not a nicety.
Toilets when the water stops
The two-bucket toilet
- Bucket 1 (pee): urine is almost sterile. Dilute and pour onto soil or a garden drain away from water sources.
- Bucket 2 (poo): line with two strong bin bags. After each use, cover with a scoop of clay cat litter, sawdust, soil, ash or shredded paper — it controls smell and flies.
- A toilet seat on a lidded 20-litre bucket, or the bagged bowl of your own toilet, works well. Keep the lid shut.
- Tie off bags when a third full; store in a lidded bin away from the house until collections resume, or bury (see below).
Burying waste SuburbRural
- Dig a trench or pit at least 30 m from any well, stream, pond or vegetable bed, and downhill from them.
- Cover each deposit with soil. Fill to within 30 cm of the top, then backfill and mark it.
- City In flats with no garden: bag, store in a sealed bin on a balcony or in a communal area agreed with neighbours. Councils usually set up emergency collection points.
Handwashing: the most important habit
Washing with little water
- Strip wash with a flannel and a bowl: face, armpits, groin, feet. 2 litres is enough.
- Wet wipes, no-rinse shampoo and dry shampoo save water.
- Wash clothes in a lidded bucket with a plunger (a "bucket washing machine"); reuse rinse water for flushing.
- Keep fingernails short — dirt under nails spreads infection.
Kitchen & rubbish
- Wash dishes in hot soapy water, then rinse in water with a few drops of unscented bleach; air dry.
- Keep food covered; flies spread disease from waste to food.
- Rubbish: separate food waste (bury or compost in a closed bin) from dry waste. Flatten and bag the rest. Rats arrive fast — keep everything sealed.
Diarrhoea & vomiting: treat dehydration fast
| Step | What to do |
|---|---|
| 1. Replace fluids | Small, frequent sips of oral rehydration solution (Dioralyte sachets, or homemade: 1 litre of safe water + 6 level teaspoons sugar + ½ level teaspoon salt). Keep breastfeeding babies. |
| 2. Isolate | One person cleans up; use gloves and a bleach solution. Separate towels; the sick person doesn't prepare food for 48 hours after symptoms stop. |
| 3. Danger signs | Very little or no urine, sunken eyes, drowsiness or confusion, blood in stools, a baby with a sunken soft spot or no wet nappies, symptoms lasting more than a few days — seek medical help by any means available. |
🩺 Health, Medicines & First Aid
In a long breakdown, GP surgeries and pharmacies close or run out, 999 may not connect, ambulances are stretched and hospitals run on generators with limited capacity. Minor problems — a cut, a chest infection, a missed tablet — can become serious. Prevention, a good kit and basic skills matter more than ever.
Medicines: build a reserve now
- Talk to your GP and pharmacist. Many will help you build a small buffer by ordering repeat prescriptions a little early each month until you have 2–4 weeks in hand. Keep the oldest stock in use.
- Keep a written list for each person: medicine names, strengths, doses, times, allergies, conditions, NHS number, GP. Medicines look alike when they're out of their boxes.
- Store medicines cool, dry and dark — and away from children.
- If supplies run low, never share prescription medicines or change doses without advice — speak to any pharmacist, doctor or nurse you can reach (rest centres and hospitals will have them).
💉 Insulin without a fridge
- Unopened insulin is kept in a fridge (2–8°C). Insulin in use can be kept at room temperature for a limited time — most for 28 days, some longer — below 25°C or 30°C depending on the product. Check your own leaflet, and note the new expiry date when you take a pen or vial out of the fridge.
- Never let insulin freeze or overheat; keep it out of direct sun and away from stoves.
- Evaporative cooling wallets (e.g. Frio, sold via Diabetes UK) keep insulin cool for around two days per soak, using only water — have one per insulin user. Don't put insulin directly on ice packs.
- Winter An unheated room is a good store; Summer a cool cellar, or a pot-in-pot clay cooler.
- Keep extra testing strips, lancets, meter batteries, hypo treatments and ketone strips.
🫁 Powered medical equipment
- Oxygen concentrators, CPAP, nebulisers, suction, feeding pumps, home dialysis — all need a backup plan now.
- Ask your supplier about backup cylinders and battery packs; ask your clinical team what to do and where to go if power fails for more than a few hours.
- Register on the Priority Services Register (call 105 or your electricity network) — you'll get priority contact and support.
- Know which hospital or community building nearby has a generator.
The 10 problems most likely to need first aid
| Problem | Key action |
|---|---|
| Cuts and wounds | Pressure to stop bleeding; clean with plenty of safe water; cover with a clean dressing; watch for infection (spreading redness, heat, pus, fever). |
| Severe bleeding | Firm direct pressure with a pad for at least 10 minutes; if a limb is bleeding uncontrollably, a tourniquet high and tight above the wound. Note the time. |
| Burns (stoves, candles, hot water) | Cool under cool running water for 20 minutes; cover loosely with cling film; don't burst blisters or use creams. Children's burns bigger than their palm need medical help. |
| Sprains, strains, possible fractures | Rest, support, cold compress, raise. Splint suspected fractures in the position found. |
| Carbon monoxide poisoning | Fresh air immediately, turn off the source, get medical help. See Light & Power. |
| Hypothermia / heat illness | See Winter and Summer. |
| Diarrhoea & vomiting | Rehydrate; isolate; hygiene. See Sanitation. |
| Chest infections | Warmth, fluids, rest. Seek help for breathlessness, chest pain, confusion, blue lips or a high fever that won't come down. |
| Toothache | Painkillers, clove oil, temporary filling material. Keep teeth clean — dental infections can become dangerous. |
| Anxiety, panic, low mood | Calm breathing, company, routine, purpose. See Community. |
Getting medical help when phones are down
- Try 999 or 112 anyway — emergency calls are prioritised and can use any network.
- Go in person to the nearest hospital A&E, GP surgery, pharmacy, fire or police station, or council rest centre. Send two people, not one, and send a written note with symptoms and the patient's details.
- Listen to local radio for the locations of emergency medical points.
📻 Communication When Phones & Internet Fail
Expect mobile signal to fade within minutes to hours of a widespread power cut: Ofcom found that only about one in five mast sites has an hour or more of battery backup. Broadband stops with your router. Digital home phones stop too — the old copper landline network is being switched off by 31 January 2027, and the new digital lines don't work in a power cut without a battery unit. Plan as if you'll be cut off from people outside walking distance.
📻 Listening: your lifeline
- The BBC is the UK's emergency broadcaster: the government can require it to broadcast emergency announcements. Main transmitter sites have backup power.
- Have a battery or wind-up radio with FM and DAB — plus medium wave (AM) if possible. BBC local radio, Radio 4 and Radio 5 Live carry emergency information.
- Radio 4 long wave (198 kHz) was switched off in June 2026 — don't rely on old advice that says to use it.
- Note the news with the time, and schedule listening (e.g. on the hour) to save batteries.
📱 Getting the most from your phone
- Texts use far less network capacity than calls and often get through when calls fail.
- 999 / 112 calls can use any available network, not just yours.
- Battery: low-power mode, low brightness, flight mode between checks, close apps. A phone with no signal searches constantly and drains fast.
- Download offline maps and keep key documents and this guide on the phone — but have paper copies too.
- If you depend on a landline (no mobile signal at home), ask your provider for the free battery backup unit they must offer (at least 1 hour).
Talking: two-way radio
| Type | Licence? | Range (typical) | Best for |
|---|---|---|---|
| PMR446 walkie-talkies (446 MHz, 0.5 W, 16 analogue channels) | No — licence-free | A few hundred metres in towns; 1–3 km in open country; more from high ground | Family, street watch, a group on the move. Cheap, simple, AA batteries. Agree a channel and code (e.g. channel 3, code 5). |
| CB radio (27 MHz, 4 W FM; 12 W SSB on the CEPT band) | No — licence-free | 5–15 km car to car; much further on good days | Vehicle and house-to-house over a few miles. Channel 9 is traditionally used for emergencies, but nobody is obliged to monitor it. |
| Amateur (ham) radio | Yes — pass an exam first (Foundation: up to 25 W) | Local to worldwide | Long-range contact; the amateur emergency network (RAYNET) supports emergency services. Learn now — it's a skill, not a purchase. |
US "FRS/GMRS" radios sold online are not legal to use in the UK. Don't fit amplifiers to CB or PMR radios — they're illegal and interfere with others.
The family communication plan (write it down)
1. Where we meet: home; if home isn't safe → a named nearby place (a friend's house, church, school); if the area isn't safe → an out-of-area place (a relative's house).
2. Who collects whom: children from school, older relatives, pets. Schools will hold children until collected — make sure they have a list of who may collect yours.
3. When we check in: fixed times (e.g. 8am and 8pm) for texts, radio calls or a visit, so silence at other times isn't alarming.
4. A message drop: if you leave home, leave a dated note inside (out of view from the street) saying where you've gone and when.
5. Out-of-area contact: one relative far away whom everyone calls or texts — long-distance links often work when local ones are jammed.
6. Printed contacts: everyone carries a paper copy of names, numbers and addresses. Few people remember phone numbers any more.
💷 Money, Documents & Information
💷 Cash is king (for a while)
- No power means no card machines, cash machines, online banking or contactless — for every shop at once.
- Keep £200–£500 per household at home in small notes and coins (shops won't have change), split between several hiding places.
- Cash is most useful in the first 1–2 weeks. After that, goods (food, fuel, batteries, medicine) and skills often matter more.
- Don't flash money; carry only what you need.
📄 Documents grab-file
- Passports, driving licences, birth and marriage certificates.
- Prescriptions and a medicines list for each person; NHS numbers; GP details.
- Insurance policies, mortgage/tenancy, bank details.
- Printed emergency contacts and family plan.
- Store originals in a waterproof, fire-resistant pouch; copies on paper in the grab bag and on an encrypted USB stick.
Information: paper beats screens
- Printed copy of this guide (and any other guides you rely on).
- Paper maps: an OS Explorer or Landranger map of your area and your routes to any fallback place, plus a road atlas of Great Britain.
- A first-aid manual (St John Ambulance or Red Cross).
- Printed contact list: family, neighbours, GP, pharmacy, vet, utilities, council.
- A notebook and pencils (pens freeze and leak; pencils always work).
🗣️ Rumours spread faster than facts
In every long emergency, rumours cause panic buying, dangerous journeys and conflict ("the army is taking food", "the water is poisoned", "the border is open"). Trust official broadcasts (BBC radio, government and council notices) first. Check anything else against two independent sources before acting. Write down what you hear, with the time and source, so you can compare.
🛡️ Security: Unrest, Looting & Dangerous Groups
Most people in a long emergency behave well — studies of disasters consistently find that neighbours help each other far more than they harm each other. But a small number of desperate, opportunistic or organised people can do a great deal of damage, and hunger changes behaviour. Your aim is not to "win" against them; it is to never be chosen as a target, and to have nothing worth the risk if you are.
How the security picture changes over time
| When | What typically happens | What to do |
|---|---|---|
| Days 1–3 | Mostly calm. Panic buying, queues, short tempers at fuel stations and shops. Opportunistic theft from empty shops and cars. | Buy early and quietly. Avoid crowds and queues after dark. Keep your car out of sight if it has fuel. |
| Days 4–14 | Shops empty. Cash and food become valuable. Burglaries of homes thought to be empty or well-stocked. Rumours spread. Some people leave cities. | Look occupied but not well-supplied. Start a street rota. Stop sharing what you have outside your trusted group. |
| Weeks 2–6 | If no relief arrives: organised looting, groups moving between areas, pressure on anyone visibly fed, warm or lit. Police and army focus on key sites. | Light, noise and smell discipline (below). Barricade quietly. Decide your trigger points for leaving. |
| Beyond | Highly variable. Areas with strong community organisation usually stabilise; isolated households and lawless areas get worse. | Be part of a group. Relocate with others if your area becomes untenable. |
Don't advertise: the "grey" household
👀 Light
- A lit window on a dark street says "they have power or fuel". Use blackout curtains, blankets or cardboard; check from outside.
- Use torches pointed down and red-light settings at night; keep lights to inner rooms.
- Don't run outdoor lights or decorative solar lights.
🔊 Noise
- A generator can be heard hundreds of metres away and tells everyone you have fuel. Run it briefly, in daylight, in an enclosed outbuilding with ventilation — never indoors.
- Keep voices, music and children's play low after dark.
👃 Smell & smoke
- Cooking smells carry — especially meat and frying. Cook simple foods, in the daytime, with lids on.
- Chimney smoke in summer stands out; in winter it is normal.
🗑️ Rubbish & talk
- Don't leave food packaging in bins or on view — flatten, bag and store it, or burn paper safely.
- Don't tell anyone outside your trusted circle what you have. Children talk — explain why it's a family secret.
- Look as thin, tired and short of supplies as everyone else when you're out.
Making your home a hard target (lawfully)
- Look occupied: curtains move, someone answers, but nothing to suggest plenty.
- Strengthen the obvious entry points first: front and back doors. Fit a London bar / door reinforcer, door chain, extra bolts top and bottom, and wedge stops. Most break-ins are through doors.
- Ground-floor windows: window locks; in a crisis, screw plywood or furniture across the inside of rarely-used windows. Keep at least two ways out for fire safety.
- Store supplies spread out and out of sight — not all in one cupboard, garage or shed. Keep a small, visible "decoy" stock you could hand over.
- Gravel paths, motion-triggered battery alarms and a dog all give early warning.
- Lock sheds, bikes, fuel cans and gas bottles away — they are the first things taken.
- Keep a fire extinguisher and fire blanket by each exit; fires (candles, stoves) are a far bigger risk than intruders.
Street and neighbourhood security
One household can't keep watch 24 hours a day. A street can. Organising early, while people are calm, is the single most effective security measure there is.
- Meet your neighbours now. Agree a simple plan: who checks on whom, a meeting point, a signal (whistle blasts, a pan banged) for "come and help".
- Watch rota: pairs, in 2–4 hour shifts, at the street's entry points at night. Watch and warn — don't confront.
- A visible, organised street deters. People looking for easy targets go elsewhere.
- Agree how you will treat strangers: polite, firm, from a distance, with others present. Direct people asking for help to official centres.
- Keep a written log of incidents and descriptions to give to police later.
If you are confronted
- Stay calm, keep your hands visible and your voice level.
- Give up things, not lives. Hand over the decoy stock, cash, or whatever they ask for.
- Keep a barrier between you (a closed door, a gate, a car).
- Get away the moment you can; make noise to attract neighbours.
- Remember descriptions and report to police when possible.
Don't:
- Don't open the door to strangers at night — talk through it.
- Don't chase or follow anyone.
- Don't threaten, bluff or show a weapon — it escalates and can make you the offender in law.
- Don't go out alone after dark or carry visible supplies through busy areas.
Trigger points: when your home is no longer the safest place
Decide these in advance with your household, write them down, and act on them without arguing in the moment:
- Homes on your street are being forced and the police aren't responding.
- Fires are spreading in your area with no fire service.
- You have been targeted once and the people know you're there.
- Water has stopped and you have no safe source within walking distance.
- You can no longer keep at least one room above about 12–14°C in winter.
- An official evacuation order is given — follow it.
If two or more are true, move to your pre-planned fallback (a relative's home, a rest centre, a retreat — see Stay, Move or Leave) in daylight, together, and quietly.
🤝 Community: Neighbours, Groups & Mutual Aid
Every long-term survival account says the same thing: groups survive, lone households struggle. A group can keep watch at night, share one fire and one cooking pot, nurse the sick, pool skills and walk to fetch water in pairs. The time to build that group is before you need it.
Start now (it costs nothing)
- Know the names of the people in the 10–20 homes around you.
- Find out who is elderly, disabled, on oxygen or dialysis, or has small children — they will need checking on first.
- Find out who has skills: nurses, carers, electricians, plumbers, mechanics, builders, gardeners, anglers, radio amateurs, ex-forces.
- Ask your council or parish whether there is a Community Emergency Plan or community resilience group, and join it.
- Share a printed contact sheet and a meeting point (a church hall, school or the house with a wood burner).
In the first days
- Hold a short street meeting in daylight: what's working, who needs help, what the plan is.
- Check every vulnerable neighbour within 24 hours, then daily.
- Agree a noticeboard (a front window, a church door) for news, needs and offers.
- Set up the watch rota (see Security).
- Agree simple rules: no one goes out alone after dark; tell someone where you're going.
Sharing without being stripped bare
Generosity holds a community together; giving everything away makes you the next person in need. A workable approach:
- Share effort and skills freely — carrying water, minding children, first aid, repairs.
- Pool some resources for one shared warm room or one big daily meal for the street. Communal cooking uses far less fuel than ten separate stoves, and lets people who have little eat without being singled out.
- Keep your household's core stash private. Contribute from a set "share" portion.
- Prioritise children, the sick, the elderly and nursing mothers.
- Trade, don't hoard: surplus of one thing for what you lack (batteries for fuel, tinned fish for medicine).
Useful barter items (small, valuable, durable)
| Item | Why it's valued |
|---|---|
| Batteries (AA/AAA), lighters, matches | Light and fire for everyone; quickly run out. |
| Painkillers, rehydration salts, plasters, sanitary products | Cheap now, priceless later. |
| Coffee, tea, sugar, salt, spices | Morale and flavour; light and long-lasting. |
| Tobacco, alcohol (small bottles) | Traditional crisis currency — trade discreetly. |
| Seeds, fishing kit, snares wire*, tools | Long-term food production. (*Check the law — many snares and traps are illegal.) |
| Skills and labour | Repairs, childcare, nursing, chopping wood — often worth more than goods. |
Morale and mental health
👶 Children, Older People, Disabled People & Pets
👶 Babies & young children
- Infant formula: store at least 4–6 weeks of the brand your baby uses, plus ready-to-feed cartons — they need no water or sterilising. Powdered formula must be made with water boiled and cooled to no less than 70°C; if you can't boil water, use cartons.
- Breastfeeding is the most resilient food supply there is — mothers need extra water and calories (roughly +500 kcal/day).
- Nappies (a month's supply, or cloth nappies + extra wipes/bin bags), barrier cream, Calpol/ibuprofen for children, a children's thermometer, oral rehydration sachets.
- Babies lose heat fast: hats, layers, sleep with a parent in a warm room (on a firm surface, not a sofa) only if that's safe; never use hot-water bottles or electric blankets in a baby's bed.
- Comfort items, books, crayons, a simple routine. Explain things honestly and calmly.
🧓 Older people
- Most at risk from cold (hypothermia can develop indoors at 10–15°C), dehydration and missed medication.
- Check twice a day in winter. Bring them into the shared warm room rather than leaving them alone.
- Keep a list of their medicines, doses, GP and allergies on paper.
- Spare glasses, hearing-aid batteries, denture supplies, continence pads.
- People living with dementia may be distressed by darkness and change — keep familiar routines and a small light on.
♿ Disabled people & medical equipment
- Register now on your electricity network's Priority Services Register (free; call 105 or your supplier) and your water company's register — they prioritise contact and help in outages.
- Powered equipment (home oxygen concentrators, ventilators, suction, powered wheelchairs, hoists, pressure mattresses, home dialysis) needs a plan: backup cylinders, battery packs, a manual alternative, and where to go — ask your equipment supplier and clinical team now.
- Know that stairlifts and lifts will stop. Move bedding downstairs early if needed.
🐕 Pets & animals
- Store 4–6 weeks of pet food and any pet medicines; dogs need about 50–60 ml of water per kg of body weight per day.
- Keep a lead, carrier, collar tag and vaccination record ready if you have to move. Many rest centres don't accept pets.
- A barking dog is an excellent alarm — but a hungry one is a burden. Plan honestly.
- Livestock and poultry: stored feed, water (cattle and horses drink a lot) and a plan for electric fences and water pumps failing.
🚗 Transport: When Cars Work — and When They Don't
Whether you can drive depends less on the car than on fuel, roads and safety. A solar storm won't damage a car; a power cut stops the fuel pumps; a fuel crisis empties the tanks of everyone else; and a long breakdown fills roads with stranded vehicles and anxious people.
| Vehicle | In a long outage | Keep ready |
|---|---|---|
| Petrol / diesel car | Works until the tank runs dry. Most filling stations can't pump without power; those that can sell out fast. | Tank at least half full at all times. Legal home fuel store (below). Siphon pump. |
| Hybrid | As petrol; plug-in hybrids lose their electric range. | As above. |
| Electric car | Works until the battery is flat; public and home chargers stop. Can power small devices from its 12 V socket or vehicle-to-load adapter. | Keep charged above 70–80% when warnings are issued; know your real range in cold weather (often 20–30% less). |
| Bicycle / e-bike | The best transport in a long breakdown: quiet, fast, carries 20–40 kg with panniers or a trailer. E-bikes become ordinary (heavy) bikes once the battery is flat. | Tyres pumped, puncture kit, spare tubes, lights, lock, panniers or trailer. |
| Motorbike / scooter | Very fuel-efficient; gets past blocked roads. | Fuel, helmet, waterproofs. |
| Trains, buses, flights | Electric trains stop with the grid; buses run while depots have fuel; flights depend on airport power, fuel and air-traffic control. | Don't plan on them after the first day. |
⛽ Make fuel last
- Petrol starts to degrade after about 6 months; add a fuel stabiliser and rotate stored fuel into the car every few months.
- Drive gently at 45–55 mph; remove roof boxes; don't idle for heat.
- Plan one trip, not several. Share journeys with neighbours.
- A full tank in a small car is often 400–600 miles — enough to reach family almost anywhere in Great Britain.
🚧 On the road in a crisis
- Traffic lights are out: treat junctions as unmarked; go slowly.
- Avoid motorways in the first days (queues, breakdowns, closures); use A and B roads and paper maps — satnav may lose GPS in a solar storm.
- Expect police checkpoints and closed roads; follow instructions.
- Keep doors locked and windows up in towns; don't stop for strangers flagging you down — report them instead.
- Car kit: blankets, water, food, torch, shovel, tow rope, jump leads, first aid, phone charger, paper maps, high-vis vest.
🥾 Moving on Foot: Routes, Pace & Safety
If you have to move and there's no fuel, you'll walk or cycle. People badly overestimate how far they can go, especially with children, packs and bad weather. Plan realistic distances, travel in daylight, and stay together.
How far can you really go?
| Who | Pace on roads/paths | Realistic distance per day |
|---|---|---|
| Fit adult, light pack (5–10 kg) | 4–5 km/h | 25–35 km |
| Average adult, 10–15 kg pack | 3–4 km/h | 15–25 km |
| Family with children 6–12 | 2.5–3 km/h | 10–15 km |
| With toddlers, older or less mobile people | 1.5–2.5 km/h | 5–10 km |
| Bicycle with luggage | 12–15 km/h | 50–80 km |
| Winter, rain, hills, night or rough ground | Expect 30–50% less. Add about an hour for every 600 m of climbing (Naismith's rule). | |
These are planning estimates, not official figures — always plan for the slowest walker and add 25–50% to timings. Day 2 is usually slower than day 1 as blisters and aches set in. Plan a rest of 10 minutes every hour and a long break at midday.
🗺️ Plan the route
- Use paper maps: quiet roads, bridleways, canal towpaths and footpaths avoid crowds and checkpoints.
- Avoid motorways, city centres, retail parks and large housing estates.
- Know where water is along the way (rivers, streams, churchyard taps, public toilets) and where you can shelter (churches, barns with permission, friends' houses).
- Have a primary route, an alternative and a "turn back" point.
- Leave a note at home (inside, out of view) with route and destination.
🚶 On the move
- Leave at first light; be in shelter before dark.
- Walk at the pace of the slowest person; keep the group in sight of each other.
- Agree signals and what to do if separated (go back to the last agreed point and wait).
- Dress to look ordinary, not "tactical" — camouflage and military kit attract attention.
- Avoid groups, queues and confrontations; step aside and let others pass.
- Drink before you're thirsty; eat little and often.
🦶 Look after feet
- Stop and tape a "hot spot" the moment you feel rubbing.
- Change into dry socks at midday; dry wet ones on the outside of the pack.
- Air feet at every long stop; keep toenails short.
🌧️ Weather
- Winter Daylight is 8 hours or less: plan short days, carry a sleeping bag even for "one day" trips, stay dry.
- Summer Walk early and late, rest in shade at midday, carry more water.
- Storm Don't set out into a red or amber warning: falling trees, flooding and exposure kill. Wait it out.
🎒 The Grab Bag: A Light Bag for Moving on Foot
A grab bag (or "bug-out bag") is what you carry if you have to leave on foot — to walk home from work, to reach a relative's house, or to move to a safer place. The biggest mistake is packing too much. A bag you can't carry for 8 hours a day is a bag you'll abandon on day one. Pack for the journey you actually plan, not every possible disaster.
Three bags for three plans
| Plan | Journey | Target weight (adult) | Focus |
|---|---|---|---|
| Get-home bag | Work/school to home, up to ~1 day on foot | 4–6 kg | Walking shoes, water, snacks, weather layer, torch, power bank, map, cash |
| 72-hour bag | Home to a known destination, 1–3 days | 8–12 kg | Adds shelter, sleep system, cooking, water filter, more food |
| Long move | Relocation, 3+ days, no certain destination | 12–16 kg | Adds tools, repair kit, more medicine; use a trolley, bike or pram to carry extra |
Children: about 10% of body weight at most — their own water, snacks, a layer and a comfort item. Adults carry the shared kit. A bike, cargo trailer, pram or garden trolley can carry 20–40 kg on roads and paths — far more than a person can.
The core list (72-hour bag, per adult)
💧 Water & food
- 1–2 water bottles (1.5 L total) + collapsible 2 L bladder
- Water filter (squeeze or straw type) + purification tablets as backup

- Foot care: blisters end more journeys than anything else. Tape hot spots early; change wet socks at every stop.
- A second pair of dry socks kept for sleeping only.
- Sanitary products and incontinence pads.
- Hearing-aid batteries, inhalers, EpiPens, insulin and its cooling pouch.
- Charger cable that fits your phone — and a car charger if you might drive part-way.
- Keys to where you're going, and its address written down.
- A child's comfort toy and a small game.
- Pet lead, food and bowl.
- Bin bags: rain cover, ground sheet, poncho, water collector.

- Water in the hot-water cylinder (often 100–200 L) and the toilet cistern — a hidden supply.
- The freezer as a cold store: fill gaps with bottles of water; frozen bottles keep food cold and become drinking water.
- Spare car key, car stocked with blankets and water, tank kept at least half full.
- Enough fuel and batteries for the cold — butane and ordinary batteries fail in freezing weather.
- Reading glasses for every adult who needs them, kept with the torches.
- Something to do — boredom and stress do real damage over weeks.
🏡 Going Somewhere Remote
The idea of escaping to the countryside is appealing, but in reality a remote place only helps if it has water, a way to heat it, food or land, and people who expect you. Turning up somewhere unannounced, with nothing, in winter, among locals who are as worried as you are, is usually worse than staying home. A retreat works when it is arranged beforehand.
| A good fallback place has… | Why it matters |
|---|---|
| Its own water: a spring, well, borehole with a hand pump, or a stream nearby | Rural homes on private supplies often still need an electric pump — check for a hand pump or gravity option. |
| Non-electric heat: wood burner, open fire, Rayburn/Aga on solid fuel, and a woodpile | Oil and LPG boilers usually need electricity too. |
| Space to grow food, and seeds/tools already there | Gardens and allotments feed people from late spring onwards. |
| People who know you and want you there | Family, friends, a shared plan. Strangers are met with suspicion in a crisis. |
| Distance from main roads and towns, but not total isolation | Too close: crowds pass through. Too isolated: no help if injured, and an easy target. |
| A route you can travel on foot or by bike if roads are blocked | Plan for no fuel. 80 km is 3–4 days on foot for a family. |
- Agree with the household there, in writing, who would come and when.
- Pre-position supplies there: sleeping bags, food, medicines, clothes, tools.
- Keep a key, and practise the route once a year — by car and by bike or on foot for part of it.
- Bring something to the group: food, skills, labour, fuel.
Rural realities
- Rural areas lose power first and get it back last.
- Septic tanks may have electric pumps; plan for a compost or bucket toilet.
- Village shops empty in a day; locals will need what's there.
- Farms are not food stores — crops are seasonal, livestock needs feed and water, and farmers protect both.
- Camping in the wild is legal in only some places (much of Scotland under access rights, parts of Dartmoor) and is very hard in a British winter.
✈️ Leaving the UK: Land, Sea or Air?
Leaving the country sounds like an escape, but it is rarely the right answer. A solar storm or energy crisis may affect much of Europe at the same time; other countries will be prioritising their own people; and the routes out — the Channel Tunnel, ferries and airports — need power, fuel and staff, and will be the first places everyone else heads for. Leaving only makes sense early, with a destination where you have a right to stay and people expecting you, and when your journey can be completed in one go.
| Route | Depends on | Realistic window | Biggest risks |
|---|---|---|---|
| ✈️ Air | Airport power, jet fuel, air traffic control (NATS), airline crews, and a working booking/payment system | Only in the first hours to day or so — and only if flights are operating | Airports close quickly when systems fail: the NATS failure of August 2023 disrupted 700,000+ passengers, and a substation fire closed Heathrow in March 2025. Thousands stranded at terminals. |
| 🚆 Channel Tunnel (Eurostar, LeShuttle) | High-voltage power (fed from both the UK and France), signalling, staff | First day or two, if running | A single power fault stopped all services for hours in December 2025. Queues of thousands at Folkestone. |
| ⛴️ Ferries (to France, the Netherlands, Spain, Ireland) | Port power, fuel, crew, booking systems; road access to the port | Days, if operating — expect long queues and cancellations | Ports become bottlenecks; roads to Dover, Holyhead, Portsmouth and Hull can gridlock. Check routes and ID rules with operators before relying on them — they change. |
| ⛵ Private boat | Your own seaworthy boat, fuel/sails, real skills, weather | Only for experienced sailors, in suitable weather | The Dover Strait is the world's busiest shipping lane (several hundred ships a day); cold water, tides and weather kill. Harbours may fill with panicking people. Legal entry abroad still applies. |
Inland or coastal: what it means for you
Inland households
- You're a long way from any port. The journey there — on congested roads, with uncertain fuel — is the hard part.
- Leaving the country is only realistic if you go in the first day or two, by car, to a ferry or the tunnel you've already booked or confirmed is running.
- For most inland households, a retreat within the UK (relatives, friends) is the better plan.
Coastal households
- Your local harbour may be where others head for. Expect crowds, theft of boats and fuel, and conflict.
- If you own a boat and have the skills, the sea can be a route to Ireland, France or the Channel Islands — but only in good weather and with legal entry arranged.
- Fishing and the sea can be a food source if you stay.
If you do leave by sea in your own boat
- You must be competent: RYA qualifications, experience of the passage, tides and night sailing. In doubt, don't go.
- Check the weather (inshore waters forecast, Shipping Forecast on BBC Radio 4 FM) — never sail into a gale warning.
- Lifejackets for everyone, worn; VHF radio (licensed), flares, EPIRB/PLB, liferaft if crossing open water.
- Cross shipping lanes at right angles (international collision rules), keep watch, and stay clear of large ships — they can't stop or turn quickly.
- Report your departure to UK customs (HMRC Pleasure Craft Report).
- Arriving in France or another Schengen country from the UK: you must clear in at a designated port of entry, with passports, and non-EU citizens can stay only 90 days in any 180. Arriving elsewhere without clearing is illegal entry.
Before you decide to leave
Ask honestly:
- Is the destination actually better? (Is it affected too? Will they let you in? Do you have a right to stay, money, a home, people?)
- Can the whole household make the journey, including the slowest member, in winter?
- Do you have valid passports for everyone? (For Ireland, British citizens don't legally need a passport under the Common Travel Area, but carriers require photo ID — take passports anyway.)
- What happens if the route closes halfway? Stranded at a port or on a motorway is worse than at home.
- If the answer to any of these is unclear: stay, and prepare where you are.
📅 The Long Haul: Weeks to Months
If the breakdown lasts beyond a few weeks, life settles into a new routine built around water, warmth, food and safety. Households that do best treat it like running a small expedition: ration early, produce what you can, keep everyone healthy, and stay organised.
Ration from day one, not when you run low
- Count it. List every food item and its calories; divide by your household's daily need to see how many days you really have.
- Eat perishables first: fridge (first 1–2 days), then freezer (while it stays frozen), then fresh fruit and vegetables, then tins and dry goods.
- Reduce, don't starve: adults doing light work can manage on 1,800–2,000 kcal/day for a long time. Children, pregnant and breastfeeding women, and anyone doing heavy work need their full share.
- Keep a multivitamin going if stores are mostly dry and tinned food.
Growing food in the UK
| Season | What you can grow or get |
|---|---|
| Spring (Mar–May) | Sow salad leaves, radishes, peas, broad beans, spinach, potatoes (first earlies in March–April). Fast crops are ready in 4–8 weeks. |
| Summer (Jun–Aug) | Harvest salads, peas, beans, early potatoes, courgettes. Sow kale, chard, beetroot and leeks for winter. |
| Autumn (Sep–Nov) | Main potato, squash and apple harvests; store in a cool, dark, dry place. Sow overwintering onions, garlic, broad beans. |
| Winter (Dec–Feb) | Kale, leeks, parsnips, sprouts and stored roots. Little grows — this is when stored food matters most. |
Keep seeds in the stash: a "survival seed" pack of open-pollinated varieties (so you can save seed), plus potatoes for planting. Sprouting seeds (mung beans, alfalfa) give fresh greens in 3–5 days on a windowsill, all year round.
Foraging, fishing and hunting — with care
- Safe, easy starts: blackberries, nettles (cooked), dandelion, wild garlic (spring), elderflower and elderberries (cooked), sloes, hazelnuts, sweet chestnuts, crab apples.
- Fishing needs a rod licence in England and Wales and permission on most waters; sea fishing from the shore is free.
- Most snares and traps are illegal or tightly regulated, and poaching laws still apply. Keeping rabbits or chickens at home is far more reliable than hunting.

🔄 When Things Come Back
Power and services usually return in stages, often patchily and with repeated cuts. The return is a dangerous time: fires, electrical faults, food poisoning, scams and a rush on shops all peak in the first days.
⚡ When the power returns
- Leave one light switched on during the outage so you know when power returns; switch everything else off at the wall to avoid a surge when it comes back.
- Turn appliances back on one at a time, over several minutes. Heaters and kettles last.
- Check for burning smells, damaged sockets or flood-damaged wiring — if in doubt, keep the circuit off and get an electrician.
- Remove any temporary generator connections. Never back-feed a generator into house wiring without a proper changeover switch — it can kill line workers.
🍗 Food & water safety
- Food that has been above 8°C for more than 4 hours (meat, fish, dairy, cooked food) — throw it away. If in doubt, throw it out.
- Food that is still frozen solid, or has ice crystals, can be refrozen.
- Follow your water company's notices: "boil water" advice can continue for days after supply returns.
- Run taps for a few minutes before use; flush water heaters if the supply was contaminated.
🚗 Getting back to normal
- Restock gradually — avoid adding to the rush.
- Expect fuel rationing and long queues for days to weeks.
- Check on vulnerable neighbours; they may be the last to be reached.
- Photograph damage and keep receipts for insurance.
📝 Learn from it
- Hold a family "what worked, what didn't" talk while it's fresh.
- Replace and rotate everything you used.
- Note the gaps — they are your shopping list for next time.
- Beware scams: fake utility workers, fake relief appeals, "emergency" price gouging.
