Cooking in a power cut in an all-electric UK home means planning to eat cold food and use hot water stored in a flask. You can use a camping stove only outdoors, in a safe outdoor space and according to its instructions. For flat-dwellers without outdoor space, stick to ready-to-eat food and flasks; never improvise with fuel-burning equipment indoors.
A power cut stops your electric hob, oven, microwave and kettle, so a stocked cupboard and a filled flask can help you manage meals safely. Keep fridge and freezer doors closed while you wait for the supply to return.
Carbon Monoxide Safety Comes First
Never use a fuel-burning stove, barbecue, heater or generator indoors during a power cut. These appliances can produce carbon monoxide (CO), a poisonous gas you cannot see or smell. The danger applies even when a door or window is open.
Why Must Fuel-Burning Equipment Never Be Used Indoors?
Camping stoves, barbecues, charcoal grills, gas heaters, patio heaters and generators burn fuel and can release CO. A working flame does not guarantee safe air, and ventilation does not make indoor use safe. Follow the National Grid’s carbon monoxide and power-cut safety advice.
Do not use these appliances in a home, garage or conservatory, even with the garage door open. Keep them out of tents attached to buildings and every enclosed or partly enclosed space. A balcony enclosure, communal hallway and stairwell are also unsuitable places to operate a stove.
Where Are the Unsafe Spaces Around a Home?
Treat spaces with roofs, walls, screens or limited airflow as enclosed or partly enclosed. That includes sheds, garages, lean-tos and covered areas where fumes could collect or enter the home through doors, windows or vents.
If you have a garden or yard, an outdoor stove may be an option only in the open air, well away from the building and its openings. Use it only as its manufacturer directs, and keep it stable and away from anything that could catch fire.
How Can a Carbon Monoxide Alarm Help?
Fit a working audible CO alarm and follow its instructions for placement, testing and maintenance. An alarm adds a warning layer, but it does not make indoor use of a fuel-burning appliance safe.
If your alarm sounds, leave the property and seek help. Do not re-enter until it is safe to do so.
Why All-Electric UK Homes Need a Different Plan
In an all-electric home, a power cut can remove every usual cooking appliance at once, including the kettle. Your safest plan starts with food you can eat cold, plus hot water prepared in advance and kept in a flask.
What Stops Working When the Power Goes Out?
Your electric hob, oven, microwave and kettle stop working when the supply fails. A toaster, slow cooker and electric rice cooker also need mains power, so they will not solve the cooking problem during the outage.
Heating and lighting may be affected too, depending on your home’s systems. Keep a torch where you can find it and avoid using a cooking appliance to heat a room.
Why Are Flats and Homes Without Gardens Different?
A flat without private outdoor space has fewer safe options for using an outdoor stove. Balconies, shared corridors and stairwells are not suitable places for fuel-burning cooking equipment, and building rules may restrict its use even in a private outdoor area.
For these homes, plan on no-cook meals and hot water stored in a flask before the power goes off. Check your tenancy agreement and building rules so you know which equipment and outdoor spaces are permitted.
What Can You Eat Without Cooking?
Ready-to-eat food is the simplest option when your electric appliances are unavailable. Choose cupboard foods that need no heating and do not rely on chilled items once their safe storage conditions have been affected.
Which Ready-to-Eat Foods Work Well During a Power Cut?
Keep a small selection of food you can eat straight from the packet or tin. Examples include tinned beans, fish, fruit or soup, ready-to-eat pouches, crackers, oat bars, dried fruit and nuts. Check labels for preparation instructions, allergens and whether a tin needs draining.
A tin opener, plates, cutlery and bottled drinking water help you make a meal without electricity. Choose foods that suit your household’s dietary needs, and rotate them as part of normal meals so they remain familiar.
What Should Flat-Dwellers Without Outdoor Space Do?
Use ready-to-eat foods and drinks poured from a flask. For a flat without a safe outdoor cooking area, do not use camping stoves, barbecues or other fuel-burning equipment indoors, on a balcony or in communal areas.
Before an outage, keep a few meals that require no preparation beyond opening a packet or tin. If you use a flask, fill it with hot water while the power is on and keep its lid closed.
How Can You Get Hot Food or Water Safely?
For an all-electric home without power, the safest way to have hot water is to prepare it before the cut and store it in a suitable insulated flask. If you have a safe open-air outdoor space, an outdoor stove is a conditional option; flat-dwellers without one should rely on flasks and cold meals.
How Can a Flask Keep Food and Drinks Hot?
Before a forecast outage, boil water with your electric kettle and pour it into a clean, heat-safe insulated flask. Keep the lid firmly closed and pour only what you need, since repeated opening lets heat escape. Follow the flask manufacturer’s guidance for hot liquids.
A flask can keep water ready for tea, instant drinks or rehydrating foods that only need hot water. Check the food packet’s preparation instructions, and do not put food into a flask unless the flask is designed for that use.
Can Heat-Retention Cooking Help?
Heat-retention cooking starts with food heated while electricity is available, then keeps it insulated so it continues cooking as it cools. A purpose-made thermal cooker or suitable insulated container can help with recipes designed for this method.
This approach needs planning before the cut: follow the recipe and equipment instructions, including safe handling and cooking requirements. It does not provide a way to start cooking once the power is already off.
When Is an Outdoor Stove an Option?
Use an outdoor stove only if you have an open-air space where it can operate safely, and follow the manufacturer’s instructions. Place it well away from the building, doors, windows and vents, and keep it away from combustible materials.
Never use an outdoor stove in a garage, conservatory, tent attached to a building, balcony enclosure or shared indoor area. If your outdoor space is sheltered or partly enclosed, choose cold food and a flask instead.
Can a Power Bank Run a Kettle?
A plug-in electric kettle needs far more power than most small power banks provide, so a standard phone-charging power bank is not a practical kettle supply. Battery-powered equipment has specific limits, and you should follow its manufacturer’s instructions.
Keep power banks for phones and small devices unless the equipment maker explicitly confirms that a particular battery system is suitable for an appliance. Do not attempt to connect a battery to household wiring or modify electrical equipment.
How Can You Keep Food Safe and Prepare Ahead?
Keep your fridge and freezer doors shut during an outage, and use official food-safety advice to decide what to keep or discard. A small store of no-cook food, drinking water and flask-ready supplies reduces the pressure to improvise.
What Does the Food Standards Agency Recommend for Fridge-Freezers?
The Food Standards Agency advises keeping fridge and freezer doors closed during a power cut to preserve the cold. Its advice explains what to do with food based on how long the supply is off and the condition of the appliances and food; check the Food Standards Agency’s guidance for consumers for the relevant time limits.
Avoid opening the doors to check the contents repeatedly. When power returns, use the FSA guidance to assess chilled and frozen food, and discard anything it identifies as unsafe.
Common Mistakes to Avoid
- Bringing a camping stove, barbecue, charcoal grill or generator inside to cook or provide heat.
- Using fuel-burning equipment in a garage, conservatory, enclosed balcony or partly enclosed space.
- Assuming an open window or garage door makes indoor use safe.
- Opening the fridge or freezer repeatedly to inspect food.
- Relying on a small phone power bank to run a kettle.
- Using a balcony, communal hallway or stairwell as a cooking area.

Frequently Asked Questions
Is it safe to cook indoors during a power cut?
No. Do not use a camping stove, barbecue, charcoal grill, generator or fuel-burning heater indoors, because carbon monoxide can build up without warning.
What can I eat without power in an all-electric home?
Choose ready-to-eat tins, pouches, crackers, snack bars and other cupboard foods that need no cooking. If you prepared hot water before the cut, a flask can provide water for drinks or foods designed to rehydrate.
How long will a fridge be safe during a power cut?
Keep the fridge door closed and follow the Food Standards Agency’s guidance for the outage duration and the food involved. Check its consumer advice on food safety in a power cut for the stated time limits.
Can I use a camping stove on a balcony?
Do not use one in an enclosed balcony or any partly enclosed space, and check your building rules before considering outdoor cooking. A stove belongs only in a safe open-air area, used exactly as the manufacturer instructs and well away from the building’s doors, windows and vents.
Will a power bank run an electric kettle?
Most small power banks designed for phones will not run a plug-in kettle. Use a battery system only when its manufacturer explicitly confirms it is suitable for the appliance, and do not improvise electrical connections.
