UK Winter Power Cut: How to Prepare Your Home

Updated 6 November 2026 · Standard formula, shown below

This guide walks you through practical steps to prepare your UK home for a winter power cut, covering essential supplies, heating, lighting, food safety, and communication. By following these steps, you’ll be able to stay warm, safe, and comfortable during an outage, and be ready to handle the unexpected.

What You’ll Need

Torch or headlamp (not candles, due to fire risk)
Spare batteries (check sizes needed)
Battery-powered or wind-up radio
Power bank for charging mobile phones
Blankets, duvets, and warm clothing
Hot water bottles (if safe to use)
Food that doesn’t need cooking (tinned goods, dried fruit, nuts, biscuits)
Manual can opener
Bottled water (at least 2 litres per person per day)
First aid kit
Any essential medication (keep a supply)
Thermos flask
Card games or books for entertainment

Step-by-Step

Check your emergency contacts. Write down important phone numbers (utility companies, your energy network operator, family, and your GP) on paper, as your phone may run out of battery. Keep this list in a visible place.
Prepare a power cut kit. Gather all the items listed above into a single box or bag and store it somewhere easily accessible, like under the stairs or in a hall cupboard. Make sure everyone in the household knows where it is.
Stock up on food and water. Keep a supply of non-perishable food that can be eaten cold. Store at least 2 litres of bottled water per person per day for drinking, plus extra for washing. Remember to include food for pets.
Keep your phone charged. Before a storm or when a power cut is likely, charge your mobile phone fully and charge a power bank. Also, consider getting a car charger for your phone.
Protect your pipes from freezing. Insulate exposed pipes in lofts and garages with pipe lagging. If a power cut occurs during freezing weather, keep the heating on a low setting if possible (many central heating systems need electricity, but if you have a gas boiler, it may work on battery backup). Alternatively, leave a tap dripping slightly to keep water moving.
Know how to turn off your electricity. Locate your consumer unit (fuse box) and learn which switch is the main isolator. In an emergency, you may need to turn it off. Also know how to turn off your gas supply at the meter.
Prepare lighting. Place torches in every main room and near the fuse box. Test them regularly. Avoid using candles as they are a fire hazard; if you must use them, never leave them unattended.
Plan for heating. If you have a fireplace or wood-burning stove, ensure you have a supply of dry wood. For everyone else, have extra blankets and warm clothing ready. Consider buying a camping stove (use only outdoors) for cooking and boiling water.
Keep a battery-powered radio. This is crucial for receiving updates from the national grid and local authorities. Tune into BBC Radio 5 Live or local stations for information.
Unplug sensitive appliances. Before a power cut is likely, unplug computers, televisions, and other electronic devices to protect them from power surges when the electricity returns. Leave one lamp plugged in so you know when power is restored.
Prepare for communication. Keep a list of emergency numbers. If you have a landline, note that cordless phones may not work without power, so keep a wired handset if possible.
Check on vulnerable neighbours. If you have elderly or disabled neighbours, offer to help them prepare and check on them during an outage.

Common Mistakes

Using candles without supervision. This is the number one cause of fires during power cuts. Always use torches or battery-powered lamps.
Running a generator indoors. Generators produce carbon monoxide, which is deadly. Always run them outdoors, away from windows and doors.
Opening the fridge and freezer. Each time you open the door, you let cold air out and spoil food faster. Keep them closed as much as possible.
Forgetting about your water pump. If you have a private water supply (borehole or well), it will stop working without electricity. Store extra water.
Not checking your emergency kit. Batteries die, food expires. Check your kit every six months and replace items as needed.
Leaving electric heaters on. If you have a portable heater, turn it off before the power goes out to avoid a fire risk when the power returns.

Tips

Keep a flask of hot water. Fill a thermos with boiling water before a storm. This gives you hot drinks for hours without using electricity.
Use a slow cooker. If you have a slow cooker, you can cook a meal before the power cut and it will stay warm for a while. But do not leave it on if you are not at home.
Layer up. Wear several thin layers rather than one thick one. This traps heat more effectively.
Close off unused rooms. Keep the curtains closed and use draft excluders to keep heat in the room you are using.
Download offline entertainment. Before a power cut, download movies, books, or games to your phone or tablet that you can watch without internet.

Troubleshooting

If your power cut lasts longer than expected or you face specific issues, here’s what to do:

If the power doesn’t come back after a few hours: Check if your neighbours have power. If they do, the problem may be in your home â€“ check your fuse box for a tripped breaker. If they don’t, it’s a network outage. Call your local network operator (the number is on your electricity bill) to report it.
If your phone dies: Use your car charger if you have one, but never run the engine in an enclosed space. Alternatively, go to a friend’s house or a public place with power.
If your food starts to thaw: If the freezer has been closed, food should stay frozen for up to 24-48 hours. If food has thawed but is still cold (below 8Â°C), it can be refrozen. If it has reached room temperature, discard it.
If you feel cold and are worried about hypothermia: Go to a warm place â€“ a friend’s house, a public library, or a community centre. If you must stay home, use extra blankets and hot water bottles.
If you smell gas: Turn off the gas at the meter, open windows, and leave the house. Do not use any switches or flames. Call the gas emergency number (0800 111 999) from outside.

Frequently Asked Questions

How long does a UK winter power cut usually last?

Most power cuts are resolved within a few hours. However, during severe storms, it can take days. The network operator will provide updates via radio and their website.

Will my central heating work without electricity?

Most gas boilers need electricity to run the pump and controls. Some have a battery backup, but if not, you’ll need alternative heating. Electric heating will obviously not work.

Can I still use my gas cooker?

Most gas cookers have electric ignition, so you may not be able to light the burners. You can use a match to light them manually if it’s safe to do so, but be careful. Electric ovens will not work.

What should I do with food in the fridge?

Keep the fridge closed. Food will stay safe for about 4 hours. After that, if the power is still off, use coolers with ice to keep perishables cold. Discard any food that has been above 8Â°C for more than 2 hours.

Will my mobile phone work during a power cut?

Mobile networks usually have backup power, so your phone may work, but the battery will drain. Use power banks and conserve battery by turning off Wi-Fi and reducing screen brightness.

Who do I call to report a power cut?

Call your local distribution network operator (DNO). The number is on your electricity bill or you can find it online. In an emergency, call 105 (free in the UK) to report a power cut.
