Candles in a power cut, without a house fire

GOV.UK Prepare is blunt about this: “Battery or wind-up torch - torches are safer than candles” (checked 29 August 2026). If you use candles anyway, London Fire Brigade asks for heat-resistant holders on a stable surface, nothing flammable nearby, and Devon and Somerset Fire and Rescue want 10cm between flames.

The honest starting point: a torch beats a candle

The government’s own preparedness kit list does not include candles. It lists a “Battery or wind-up torch”, and gives the reason in the same breath: “torches are safer than candles” (GOV.UK Prepare, checked 29 August 2026).

Citizens Advice says the same thing from the other direction in its power cut advice: “Avoid using candles as lights - these can cause fires if left alone” (checked 29 August 2026).

So if you are reading this before a power cut, the useful thing to buy is not a nicer candle. It is a torch, and the batteries to go with it. The home emergency kit page covers what else belongs in the drawer.

If you are going to use candles, here are the rules, word for word

Most people have candles in a cupboard and will light them when the lights go out. That is human. These are the instructions the fire services actually give, quoted rather than summarised, because the summary is where the danger creeps in.

London Fire Brigade, on its candles page (checked 29 August 2026):

“Keep them in heat-resistant holders placed on a stable surface.”

“Don’t put them close to anything that can catch fire, such as curtains, papers, furniture, and clothes.”

“Never leave candles, incense sticks and oil burners unattended.”

“Make sure you put them out when you leave the room and especially before bed.”

“To avoid accidents keep candles and all naked flames (including matches and lighters) out of the reach of children and pets.”

“Tea lights get very hot and without proper holders can melt through plastic surfaces like a TV or bath.”

Devon and Somerset Fire and Rescue Service adds three more (checked 29 August 2026). Its “do” list includes “make sure that candles are placed in a fire-resistant candle holder”, “keep candles away from furniture and curtains”, “leave at least 10cm between burning candles and tea lights”, “put out candles before leaving the room and before you go to bed”, “use a snuffer or spoon to put out candles” and “keep candles, matches and lighters away from children and pets”.

Its “don’t” list is shorter and sharper. Don’t “put them under shelves or in enclosed spaces”, don’t “ever leave a burning candle unattended”, don’t “blow out candles, it can send sparks and hot wax flying”, don’t “use candles in, or near a tent”, and don’t “move a candle while it’s lit”.

The three places a candle should never be

Read the quotes above again and three no-go zones fall out of them.

The bedroom is the one people get wrong. A candle on a bedside table is a candle next to bedding, next to a person who is trying to fall asleep, in the room with the lowest chance of anyone noticing. If you want light by the bed, put a head torch there instead.

Snuff, don’t blow

Blowing out a candle looks harmless and is not. Devon and Somerset Fire and Rescue Service’s don’t list is explicit: don’t “blow out candles, it can send sparks and hot wax flying”.

Use a snuffer if you have one. A metal spoon held over the flame does the same job, and so does the lid of a jar candle. Then look at the wick and make sure it has stopped glowing before you walk away.

Three better options, in order

A head torch. Hands free, points where you look, and it cannot fall over onto a duvet. This is the single best thing to own for a dark house, and it is what most people wish they had bought after their first evening power cut.

Battery or wind-up lanterns. A lantern lights a whole room the way a candle pretends to. A wind-up one has no battery to be flat. GOV.UK Prepare’s kit list is built around exactly this: “Battery or wind-up torch”.

LED candles and USB fairy lights. London Fire Brigade calls flameless LED candles “a much safer alternative to real candles or tea lights” and notes “You can leave them unattended”. A string of USB fairy lights running off a power bank gives a room a soft, useful glow, and the power bank is on the government’s kit list anyway.

For everything else that happens when the lights go out, see what to do in a power cut and keeping the fridge cold.

Smoke alarms are part of candle safety

Devon and Somerset Fire and Rescue Service pairs its candle advice with a reminder to make sure “you have working smoke alarms in your home”. A power cut is a good moment to notice that mains-powered alarms with a battery back-up keep working, and to press the test button on each one this week rather than in the dark.

If clothing catches fire

London Fire Brigade’s instruction, verbatim (checked 29 August 2026):

“Stop – don’t run around, you’ll make the flames worse. Drop – lie down on the ground at once. Roll – it makes it harder for the flames to spread.”

Then call 999.

On the burn itself, the NHS says to “Hold the burn or scald under cool running water for 20 minutes”, and to “Do this as soon as possible, within 3 hours of it happening”. It also says to remove clothing or jewellery near the affected area, but not to remove anything that is stuck to it (NHS, checked 30 August 2026).

The NHS’s own line on emergency help is to “Call 999 or go to A&E if” a burn or scald “is very large or deep”, “is on your face, genitals or bottom”, or “has been caused by an acid or chemical, or by electricity”, and it adds “Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance” (checked 30 August 2026). We describe official guidance here rather than giving medical advice.

What this asks of your body

Very little, which is the point. But moving confidently around a dark house, getting down to floor level and back up again, and carrying a child downstairs are all easier if you have kept a bit of strength and balance. The five ready body tests are the quiet version of that preparation.

Frequently asked questions

Are candles safe to use in a power cut?

Safer options exist. GOV.UK Prepare recommends a “Battery or wind-up torch” because “torches are safer than candles”, and Citizens Advice says “Avoid using candles as lights - these can cause fires if left alone”. If you do use candles, follow the fire service rules quoted above exactly.

What should a candle stand in?

London Fire Brigade says “Keep them in heat-resistant holders placed on a stable surface”. Devon and Somerset Fire and Rescue Service says “make sure that candles are placed in a fire-resistant candle holder”. A saucer is not a holder, and a wobbly table is not a stable surface.

Should I blow a candle out?

No. Devon and Somerset Fire and Rescue Service’s advice is to “use a snuffer or spoon to put out candles” and not to “blow out candles, it can send sparks and hot wax flying”. Check the wick has stopped glowing before you leave the room.

Can I leave a candle burning while I sleep?

No. London Fire Brigade says “Never leave candles, incense sticks and oil burners unattended” and “Make sure you put them out when you leave the room and especially before bed”. If you want light where you might doze off, use an LED candle or a head torch.

Are tea lights safer than ordinary candles?

Not automatically. London Fire Brigade warns that “Tea lights get very hot and without proper holders can melt through plastic surfaces like a TV or bath”. They need a proper holder like any other candle, and Devon and Somerset Fire and Rescue Service asks for “at least 10cm between burning candles and tea lights”.

What about LED candles?

London Fire Brigade describes flameless LED candles as “a much safer alternative to real candles or tea lights” and notes “You can leave them unattended” and “If you doze off while a flameless candle is on, it’s not a problem”. They are the sensible swap if you like the look of candlelight.

How many candles should I keep at home?

That is the wrong question to plan around. Buy the torch first, add spare batteries, and treat candles as decoration rather than lighting. If you want a stored light source that never needs batteries, a wind-up lantern does the job.
