How to Cope With a Power Outage: A Practical Guide

Power cuts used to be rare. Most people under forty have never experienced one that lasted more than a few hours. That changes the equation entirely — not because the risks are new, but because the knowledge to handle them has eroded from everyday life.

A power outage isn’t a disaster in itself. What makes it dangerous is the cascade of things that depend on electricity: lights, heating, cooking, refrigeration, communications, banking, water pumps. Lose electricity and all of those systems stop. The question isn’t whether you’ll cope — it’s whether you know how to.

This guide covers what to do when the power goes out and stays out. It’s written for the home environment. The goal isn’t to panic or to bug out anywhere — it’s to stay in your home, use what you have, and keep yourself and your family safe, warm, fed, and informed until the power comes back.

Immediate Actions (First Ten Minutes)

The first few minutes matter most. Before anything else:

• Stay calm. The power is gone. This is manageable. Panic burns energy and leads to bad decisions.
• Check if it’s just your property or the whole area. Look outside — are the street lights on? Are neighbours’ windows lit? If only your house is dark, check your fuse box or consumer unit. If the whole street is dark, it’s a network outage.
• Preserve your phone battery. Resist the urge to check it constantly. This is now a limited resource. Put it on airplane mode if you’re not using it.
• Open curtains and blinds. Use daylight while you have it. This is the most obvious step and the one most people forget in the panic of going dark.
• Don’t open the fridge or freezer. Cold air falls out quickly. Every time you open the door you shorten how long your food stays safe.

Lighting

Without electric light, darkness inside after sunset is nearly total. This is where people first feel the psychological weight of a power cut.

Candles are the obvious answer, but they need to be used properly:

• Use candle holders — never leave a candle resting on a surface unprotected. Wax can drip onto and damage surfaces, and a tipped candle is a fire risk.
• Keep candles away from anything flammable: curtains, bedding, clothing, paper.
• Never leave candles burning in a bedroom when you’re sleeping. Put them out first.
• Tea lights are useful because they fit in ordinary saucers and are cheap to stock up on.

Torches and lanterns are safer than candles for moving around at night. Keep several distributed around the house — not all in one drawer in the kitchen. A headtorch is particularly useful because it leaves both hands free.

Power bank battery packs can run LED lanterns or provide phone charging. Keep these charged in normal times so they’re ready.

Torches need batteries. This sounds obvious, but check your torches every six months. Replace batteries annually even if they seem fine — batteries leak, and a torch with dead batteries is useless when you need it.

Heating Without Electricity

This is often the most serious concern, particularly in winter. Most gas central heating systems need electricity to run the fan, pump, and controls. A power cut means no central heating, even if the gas is flowing.

The key principle: trap the heat you have, and generate small amounts of heat strategically.

Retain Heat

• Close curtains, especially at night. Heavily lined curtains make a significant difference.
• Close internal doors to trap heat in the rooms you’re using.
• Stuff towels or clothing against the bottom of external doors to reduce draughts.
• Use rugs on bare floors — concrete and tile floors draw heat from the room very quickly.
• If you have a fireplace, don’t light it until you’ve checked the chimney and flue are clear. Blocked flues cause smoke to fill the room.

Generate Small-Scale Heat

• A room that is 18°C is comfortable. You don’t need to heat the whole house — just one room where the family spends the evening.
• Hot water bottles filled with boiling water and wrapped in a towel are safe and effective for direct warmth.
• Body heat is a heat source. Extra layers, extra blankets, sharing a room — these all help.
• Hand warmers (the reusable iron-based ones you shake to activate) are cheap, non-flammable, and last for hours.

If You Have a Wood Burner or Open Fire

• Burn dry, seasoned wood. Green or wet wood produces far less heat and creates dangerous tar deposits in the chimney.
• Use a fireguard if you have children or pets in the house.
• Always crack a window slightly when burning anything inside. This prevents a build-up of fumes, particularly with open fires.
• Never use petrol, white spirits, or accelerants to light a fire — the flash point can cause an explosive flare-up.
• Keep a supply of kindling and firelighters accessible, not at the bottom of a damp log store.

What Not To Do

• Don’t bring a barbecue inside. The carbon monoxide from burning charcoal in an enclosed space is lethal. This has killed people.
• Don’t use camping gas heaters inside without ventilation. Same reason.
• Don’t try to heat your home with a gas oven. It’s not designed for it and produces both carbon monoxide and moisture that damages the house.

Cooking Without Electricity

If you have a gas hob, that works independently of electricity — gas cookers are typically fine in a power cut. The grill and oven on most gas cookers also work by gas alone.

If you rely on electric cookers, you’ll need alternatives:

• BBQ outside — only if used outdoors. Do not bring a lit or recently-lit BBQ inside.
• Camping stoves — keep a small gas cartridge stove and spare cartridges. Use outdoors or in a well-ventilated area with a window open.
• Tea light candlestoves — a DIY option using tea lights and terracotta pots. They produce very limited heat but can be useful for warming hands and small amounts of food. Never leave unattended.
• Fire outside — if you have a firepit or suitable outdoor space, you can cook on an open fire using a grill grate or suitable metal skewers.

Water

In most UK homes, the water supply is mains pressure and continues working during a power cut — the water tower gravity-feeds your house, so the pump station power doesn’t directly affect your taps.

The risk is if your house has an electric pump for water pressure, or if you’re on a private borehole or supply that relies on an electric pump. In those cases:

• A stored water tank (header tank) in the loft provides a buffer — most houses have one, and it will gravity-feed as long as there’s water in it.
• Fill baths, sinks, and any large containers early in an outage. This gives you a reserve for flushing toilets and emergency use.
• Turn off the mains stopcock if there’s a risk of losing supply and you need to preserve what’s in the pipes.

If the water supply is interrupted or you suspect contamination: boil water for at least one minute before drinking, or use water purification tablets. Our water purification guide covers filtering, bleach disinfection, and finding water sources in detail.

Food Storage and Safety

The fridge keeps food safe for roughly 4 hours unopened. A full freezer can last 24–48 hours if unopened, depending on how full it is and the ambient temperature. Do not open the freezer to ‘check’ — every opening costs you hours of safe storage time.

• Eat food from the fridge first — dairy, fresh meat, leftovers, cut fruit.
• Then the freezer — defrosted food should be used within 24 hours of thawing.
• Then your store cupboard — tinned and dried foods don’t need refrigeration.

A cool bag or box with ice blocks can extend the safe period for refrigerated food if the outage lasts into the next day.

Basic cupboard stores worth keeping: tinned tomatoes, tinned beans, dried pasta, rice, oats, stock cubes, peanut butter, biscuits, long-life milk. These require no refrigeration and provide nutrition without needing cooking.

Communications

Mobile phone networks have battery backup at their towers — typically 4–48 hours. Landlines (if you have one) usually keep working. But your phone is useless if the battery is dead.

• Keep a power bank charged and use it to top up phones sparingly.
• A car phone charger — run the engine for 20 minutes every few hours to charge devices. Do this in a ventilated space (open garage or outside) — running a car in an enclosed garage produces lethal carbon monoxide.
• A crank radio or solar radio receives BBC Radio 4, which broadcasts emergency information. A wind-up or solar torch also serves this purpose.
• Text messages use far less battery than calls or internet. Send texts instead of calling.

Sanitation

Toilets that use a cistern connected to the mains water supply will stop refilling after the last flush. Wastewater pumps in flats and some houses also stop without power.

• Don’t flush unnecessarily. A half-flush using a bucket of water is more water-efficient anyway.
• Keep a bucket with a lid next to the toilet. Fill it with water from the bath or sink when needed for flushing.
• Pour a small amount of water directly into the pan, swill, and empty into a waste bucket if the cistern won’t fill.
• Chemical toilet fluids (available from camping shops) contain the smell in the bucket between uses.
• Hand sanitiser replaces hand washing when water is scarce — keep a large bottle in the bathroom.

Mental State and Keeping Calm

The psychological dimension of a power outage is real and underestimated. Darkness, cold, not being able to cook, not knowing how long it will last — these things cause stress even when there’s no physical danger.

• Have something to do. A board game, a book, a pack of cards. Boredom and anxiety are related. Keeping occupied helps more than you’d expect.
• Talk to neighbours. A power cut is a good reason to speak to people you’d normally just nod at. Someone else’s torch is useful. Information about how long the outage might last is valuable.
• Don’t speculate. Rumours spread fast in an outage. Don’t spread them further. Wait for information from official sources: BBC Radio, your Distribution Network Operator’s website if you have mobile signal.
• Get sleep. Anxiety makes people stay up all night — watching, waiting, worrying. This is exhausting and makes everything worse the next day. Light a candle, get under the blankets, and sleep if you can.

When the Power Comes Back

• Switch appliances back on gradually — don’t turn everything on at once when the network is re-energising.
• Check the fridge and freezer. If food has defrosted and been above 8°C for more than 2 hours, dispose of it. Don’t refreeze thawed food.
• Reset clocks, alarm clocks, cookers, and any timers.
• Report any damage to the network operator if lines or equipment were affected.

Being Prepared: What to Have in Advance

You can’t prepare for everything, but having a few things ready makes an outage manageable rather than stressful:

• Candles (and matches or a lighter) — in a visible, accessible location
• A torch per person, or at least one per room
• A wind-up or solar radio
• A power bank, kept charged
• Spares of any essential medication
• A cupboard with a week’s worth of basic tinned and dried food
• Hot water bottles
• Battery stock for torches and radios, renewed annually
• A first aid kit

None of this is expensive or elaborate. It’s the difference between a power cut that’s an inconvenience and one that becomes a crisis.
