What to buy for a power cut

Six things for a power cut: a battery torch, spare batteries, a wind-up radio and a power bank kept in one drawer, plus a battery carbon monoxide alarm and LED tea lights instead of candles. Report the cut on 105.

Reviewed by the What to Buy For team · updated 26 September 2026

Why this basket

  • The kit follows gov.uk's Prepare advice: a battery or wind-up torch, a battery or wind-up radio, spare batteries and a portable power bank.
  • LED tea lights stand in for candles because gov.uk says torches are safer than candles and London Fire Brigade calls flameless LED candles a much safer alternative.
  • The carbon monoxide alarm runs on batteries, so it keeps working with the mains off, and fire services warn against running barbecues and generators indoors.
  • Keeping warm is on the cold house page, so this basket stays on light, news and safety.

Can wait

  • A portable power station. Gov.uk's list asks for a power bank for phones. For laptops or bigger loads, see the power bank vs power station comparison.
  • A head torch. Handy for cooking or the stairs, but gov.uk's list only asks for one battery or wind-up torch.

    Real candles as the main light
    Gov.uk says torches are safer than candles. If you do light one, London Fire Brigade says use a heat-resistant holder on a stable surface away from curtains, and put it out when you leave the room.
  • Skip
    A generator or barbecue indoors
    Shropshire Fire and Rescue says a generator should always be kept and run outdoors, and the NHS says never to use a barbecue or camping stove indoors, because of carbon monoxide.

Quick questions

What number do I call in a power cut?

105 in England, Scotland and Wales, and 03457 643643 in Northern Ireland, according to gov.uk's Prepare site. It suggests writing the number down on paper, so you still have it if your phone is flat.

What is the Priority Services Register?

A register that lets your energy supplier know you need additional support. Gov.uk's Prepare site says to sign up with your supplier if you are eligible; your supplier can tell you who qualifies.

How long will the fridge and freezer stay cold?

Several hours, if you keep the doors closed, says gov.uk's Prepare site. It also says to turn off items such as irons, ovens, electric fires and fryers during the cut.

Can I use a camping stove or barbecue indoors in a power cut?

No. The NHS says never to use a barbecue or camping stove indoors, and Greater Manchester Fire and Rescue says a barbecue still gives off carbon monoxide after the flames have gone out. Generators belong outside too, says Shropshire Fire and Rescue.

Where should a carbon monoxide alarm go?

In each room with an appliance that burns gas, oil, coal or wood, such as a boiler, gas fire or log burner, according to the NHS and Greater Manchester Fire and Rescue. Choose an audible alarm that meets EN 50291. A battery alarm keeps working in a power cut. If you suspect a gas leak or carbon monoxide, the National Gas Helpline is 0800 111 999.
