An all-electric home needs a power-cut plan for heat, hot water, lighting, food, communications and access. Keep torches, charged power banks, stored drinking water and key contact details ready, and know how to report a cut on 105 in Great Britain. If anyone relies on powered medical equipment, agree a backup plan with their care team and network operator before an outage.
A brief local cut may be manageable with supplies at hand. A longer outage needs more planning, especially in a flat where lifts, entry systems or water pumps may also stop.
Why All-Electric Homes Need a UK-Specific Plan
In an all-electric home, one network fault can affect several everyday services at once. The UK electricity system is resilient, and most power cuts are short and local, though severe weather and system faults can also cause wider outages.
Which Everyday Services Stop Working When the Power Goes Off?
Your heating, hot water and cooking may all stop if they rely on electricity. A heat pump needs power to run, and many gas boilers also rely on electrical controls and pumps. A mains-gas supply on its own does not guarantee that a boiler will keep heating your home.
You may also lose lighting, broadband, powered doorbells, alarms, electric gates and garage doors. Your mobile phone might still work, though local masts and the broadband router need power; service can be affected if network equipment loses backup power or mobile coverage is disrupted.
In a flat, the building may also depend on electricity for lifts, communal entry systems and water pumps or boosters. Check your building’s arrangements and keep its emergency contact details and entry instructions somewhere you can reach without a phone.
What Changes Between a Short Cut and a Longer Outage?
During a short cut, your immediate tasks are to confirm the outage, use safe lighting and conserve phone charge. Keep fridge and freezer doors shut, and avoid using electrical appliances until power is stable.
As an outage continues, warmth, drinking water, medication storage, accessible building entry and charging become more pressing. Decide in advance where you could go if your home becomes too cold or inaccessible, and how you would get there safely.
What Should You Prepare for First?
Prepare for the needs that become urgent when electricity is unavailable: warmth, safe movement, food and water, communication, and health support. Keep supplies together in a known place and include the needs of everyone in your household.
How Can You Keep Warm Without Electric Heating?
Choose a warm room where your household can gather, and keep blankets, warm layers and a torch there. Close doors to unused rooms and use curtains to reduce heat loss, while keeping ventilation and safe exits clear.
Plan where you could stay if the home becomes too cold, such as with a trusted person nearby. Never use a barbecue, camping stove, charcoal burner or outdoor generator inside or in an enclosed space; carbon monoxide can build up without warning.
How Will You Manage Lighting and Moving Around Safely?
Keep torches and spare batteries in known, reachable places, including near the bed and by the exit. A wind-up light can provide another option, and a small battery-powered light is safer for routine use than a candle.
Clear walkways and keep essential items away from stairs. In a flat, learn the stairs and evacuation routes before an outage, and follow your building’s lift and evacuation instructions.
What Should You Know About Food and Water?
Keep drinking water available and store some easy-to-eat food that does not need heating. For cooking options during an outage, see separate guidance on cooking in a power cut; never bring outdoor cooking equipment indoors.
The Food Standards Agency advises keeping fridge and freezer doors closed during a power cut to keep food cold for as long as possible. Avoid opening the doors to check contents, and follow food-safety advice before eating chilled or frozen food after an extended outage.
How Can You Stay in Touch and Get Updates?
Keep your phone charged and store a charged power bank with its cable. Use a battery or wind-up radio for updates if mobile data or home broadband is unavailable, and write down key contact details in case your phone runs flat.
For an outage in Great Britain, 105 connects you to the local electricity network operator. Network operators provide updates about local faults; your electricity supplier handles your bill, while the operator manages the network equipment that delivers electricity.
What If Someone Relies on Powered Medical Equipment?
Make a written outage plan with the person’s care team, including what to do if equipment loses power and where to get help. Register with the electricity network operator’s Priority Services Register if someone in your household has additional support needs.
Keep the operator’s emergency contact details and equipment instructions accessible on paper. Follow the care team’s guidance for the equipment and its backup arrangements; this plan does not replace medical advice.
What Should You Do When the Power Goes Off?
Start by checking whether the problem affects your home alone or the surrounding area, then report a network outage and follow local safety instructions. Keep movement, food storage and communication under control while you wait for updates.
How Do You Report an Outage and Get Support?
Check whether neighbours or street lights have also lost power. If the outage appears local to your property, check your consumer unit for a tripped switch; do not touch damaged equipment or exposed wires. National Grid’s power-cut advice explains these initial checks.
In Great Britain, call 105 to reach your network operator or use its outage-reporting service. Northern Ireland uses different arrangements, so check your local electricity network provider. Tell the operator if someone in the home depends on powered medical equipment or needs extra support.
What Should Flat-Dwellers Know About Lifts and Building Access?
Follow your building’s instructions about lifts during an outage, and use the stairs when advised. If someone is trapped in a lift, use the lift alarm or building emergency contact and wait for trained help.
Keep the building manager’s number, entry arrangements and accessible evacuation information on paper. Ask how communal doors, gates and water pumps work during an outage, and check your tenancy or building rules before relying on any backup equipment.
How Can You Keep Food Safe and Conserve Phone Charge?
Keep fridge and freezer doors shut, and use a power bank only for small devices such as phones. Turn off non-essential phone features, lower screen brightness and check messages periodically instead of leaving the screen on.
A plug-in power bank or portable power station is not a way to power household circuits. Never connect equipment to a wall socket to feed electricity back into the home; any fixed backup system needs suitable equipment installed by a qualified electrician.
Put Your Household Plan Into Practice
A usable plan assigns simple tasks, lists your household’s needs and shows what you can do if the outage lasts. Keep a printed copy with emergency contacts and review it when household or building arrangements change.
Quick-Reference Plan for Your Home

Frequently Asked Questions
How likely is a nationwide blackout in the UK?
A nationwide blackout is not the usual pattern: the UK electricity system is resilient, and most cuts are local and short-lived. Your plan should still cover a longer outage, since wider and longer cuts can happen.
How long can you be left without power in the UK?
Many power cuts are short, though the duration depends on the cause, location and repair work. Your network operator can provide local updates through 105 in Great Britain.
How do I report a power cut in my area?
Call 105 in Great Britain to reach your local electricity network operator, or use its outage-reporting service. Northern Ireland has different arrangements, so use the local provider’s contact route.
Should I open my fridge or freezer during a power cut?
Keep both doors closed so they stay cold for as long as possible. Follow Food Standards Agency guidance before eating food after a prolonged outage.
Can a portable power station run your electric heating?
A portable power station is intended for compatible devices within its rated capacity, and household electric heating may require far more power than small-device charging. Check the equipment specifications and ask a qualified electrician about any fixed backup system; never feed power into a wall socket.
