Smoking, Matches and Lighters: Fire Risk at Home

Smoking materials cause more fatal house fires in the UK than anything else. Devon and Somerset Fire and Rescue Service states it plainly: "Smoking is the biggest cause of fatal fires"¹. Nationally, someone dies from a fire started by a cigarette roughly every six days¹, and fires started by smoking materials account for one third of all accidental fire deaths². Smoking-related house fires are more likely to cause death and injury than any other cause of house fire¹.

The numbers are stark because of how these fires start. Cooking causes more accidental fires overall, over 50 per cent of them, but smoker's materials are the main cause in fatal fires in the home³. A dropped cigarette does not flare up at once: it smoulders, often in a sofa or bedding, sometimes while the person who dropped it has fallen asleep. By the time there are flames, the room can be full of smoke.

The good news is that every fire and rescue service in the UK gives the same short list of habits that prevent nearly all of these fires: never smoke in bed or when tired, never leave anything lit unattended, stub cigarettes out properly every time, keep lighters and matches away from children, and fit a working smoke alarm. This page sets out that advice, what to do about each risk, and where to get help to quit, which fire services themselves describe as the best prevention there is.

Why smoking is the top cause of fire deaths

Fire and rescue services across all four nations are unanimous on this. Greater Manchester Fire and Rescue Service says smoking is the top cause of accidental fire deaths nationally and in Greater Manchester⁶, and the Northern Ireland Fire & Rescue Service calls it "the number one cause of accidental fire deaths in the home"⁷. Lincolnshire's fire safety guidance states that more people die in fires caused by smoking than from any other cause⁸, and the London Fire Brigade calls smoking the leading cause of fire fatalities⁹.

The scale is easiest to see in the figures. Smoking materials such as cigarettes and cigars accidentally start almost 2,000 fires in the home every year⁴. In London alone in 2026, the Brigade reported the equivalent of more than two smoking-related fire incidents every day, with four people killed and 55 people injured¹⁰. In Northern Ireland, the Fire & Rescue Service reported smoking materials as the leading cause of fatal house fires, accounting for 43 per cent of such deaths over the past ten years¹¹.

Two things make smoking fires unusually deadly compared with, say, kitchen fires. First, they often start where a person is sleeping or drowsy, so the fire has time to grow before anyone reacts. Second, they smoulder before they flame, which means a smoke alarm may be the only warning. That is why the same services that rank smoking as the top cause also put smoke alarms at the centre of their advice: a working smoke alarm greatly reduces the risk of injury or death due to fire¹², and you are 4 times more likely to die in a domestic fire if you do not have one³.

If a fire does start, what you do in the first minute matters. Read what to do if a fire starts in your house and make a fire escape plan before you need one.

Never smoke in bed, and never smoke when tired

This is the most repeated instruction in UK fire safety advice, and every service phrases it the same way. Greater Manchester Fire and Rescue Service: "Never smoke in bed or when you're tired. It's easy to fall asleep with a cigarette burning and set furniture, clothes or bedding alight"⁵. The Scottish Fire and Rescue Service adds the armchair and sofa to the warning: if you're drinking or are feeling tired, never smoke in bed or on an armchair or sofa¹³.

The reason is simple. A cigarette burns for several minutes, and a person who is tired, has been drinking, or has taken drowsy medication can fall asleep long before it is out. The cigarette drops, the bedding or clothing catches, and the person sleeps through the critical minutes. nidirect's guidance for Northern Ireland households puts it as a rule for all accidental house fires: never smoke in bed or when feeling drowsy or tired¹⁴.

The Northern Ireland Fire & Rescue Service lists the situations in which you should never smoke at all⁷:

• Never leave any smoking materials unattended
• Never smoke in bed
• Never smoke if you have taken medication that makes you feel drowsy or if you have consumed alcohol
• Never smoke near oxygen therapy equipment or an airflow mattress
• Do not smoke near clothing, bedding or dressings contaminated with emollient creams

The last two points matter for households where someone is ill or being cared for. Oxygen therapy equipment and airflow mattresses are common in homes with serious illness, and emollient skin creams soak into fabric and make it easier to ignite. If someone in your home uses oxygen, read our page on fire safety when someone uses oxygen therapy, and for creams, see are emollient creams a fire risk?.

The London Fire Brigade's 2026 warning adds one more habit to watch: avoid smoking on armchairs and sofas, especially if you think you might fall asleep¹⁰. If you need to lie down, don't light up, as Mid and West Wales Fire and Rescue Service puts it: "You could doze off and set your bed on fire"¹⁵.

Alcohol makes smoking fires far more likely

Alcohol deserves its own mention because it appears again and again in the fatal fire figures. Nationally, more than half of home fire fatalities involve alcohol or drug-related behaviour, usually people falling asleep while cooking or smoking¹⁶. The Northern Ireland Fire & Rescue Service notes that alcohol significantly affects behaviour and is a major contributing factor in fire-related deaths and injuries, and that many fire deaths where alcohol is a contributing factor involved people who lived alone⁷.

The Scottish Fire and Rescue Service makes the link directly: many fires started by cigarettes happen to people who have also been drinking and are sleepy¹³. That combination, a lit cigarette, alcohol and a soft chair or bed, is the pattern behind a large share of smoking fire deaths.

The practical advice follows from the pattern. If you are drinking:

• Smoke outside rather than indoors¹⁷
• Never smoke in bed or on an armchair or sofa¹³
• Do not light candles or start cooking¹⁷
• Stub cigarettes out fully before leaving them¹⁸

The Northern Ireland Fire & Rescue Service's student safety advice applies the same rules to an evening with friends: avoid cooking, do not light candles, avoid electric heaters and smoke outside¹⁷. The same service noted during the festive period that the risk of accidents is greater after alcohol is consumed¹⁹.

Putting cigarettes out properly, every time

The government's Prepare campaign gives the instruction in four words: "Stub cigarettes out properly and dispose of them carefully, put them out, right out"²⁰. A cigarette that looks finished can still be smouldering inside, and that is how bin fires and sofa fires start hours after the smoker went to bed.

The habits that fire services ask for are simple:

• Always stub cigarettes out fully in an ashtray¹⁴
• Never leave a lit cigarette, cigar or pipe lying around⁶
• Do not leave lit cigarettes, cigars or pipes unattended, as they can easily over-balance as they burn down²
• Empty ashtrays regularly, and make sure cigarettes are completely extinguished before they go into the outside bin¹⁷

That last point catches many people out. A cigarette stubbed in an ashtray can stay hot enough to ignite bin contents, so the Northern Ireland Fire & Rescue Service's advice is to make sure cigarettes are extinguished correctly and ashtrays emptied safely²¹. Tip ashtray contents into the outside bin only when you are certain nothing is still burning, and never into an indoor bin or a bag of rubbish in the house.

Use a proper ashtray, one that is deep and stable and cannot be knocked over. Devon and Somerset Fire and Rescue Service lists inappropriate ashtrays, such as butter tubs, among the warning signs of fire risk in a smoker's home²². An overflowing ashtray is on the same list, because stubs balanced on a full ashtray fall off easily.

Why smoking fires go unnoticed: they smoulder first

Fires started by smoking materials can smoulder and go unnoticed at first²³. This single fact explains most of the death toll. A chip pan fire is loud, bright and immediate; a cigarette dropped down the side of a cushion can burn slowly and smokelessly for a long time before flames appear, and the person closest to it may be asleep.

The same behaviour appears outdoors. Dorset and Wiltshire Fire and Rescue Service warns that residual heat and embers can cause hidden smouldering fires underground, sometimes for a number of days, before spreading to surface vegetation²⁴. A cigarette end that seems harmless can hold heat far longer than it looks like it should.

This is why smoke alarms matter more for smokers than for anyone else. A smouldering fire produces smoke before it produces flames, and an alarm in the right place buys the minutes that a fast fire would not give you. Suffolk's home fire safety guide notes that you can have linked alarms installed, so that when one alarm detects a fire they all go off together, which is useful in a large house or over several levels²⁵. For choosing and placing alarms, see our guides on smoke alarms, where to fit smoke alarms and interlinked alarms.

It is also why you should never leave a room with anything still burning, and never assume a cigarette has gone out because it has stopped glowing. Check it, wet it if in doubt, and only then walk away.

Matches and lighters: keeping them out of children's hands

Children and fire-starting tools are a dangerous mix, and fire services treat this as part of smoking fire prevention. The London Fire Brigade's advice is to keep matches and lighters out of children's reach, and to buy child resistant lighters⁹. The Northern Ireland Fire & Rescue Service goes further: never let children play with matches or cigarette lighters, teach children not to play with fire, and keep matches and lighters where children are not tempted to play with them⁷.

Warwickshire's guidance adds two points for the whole household. Teach children about the risk of smoking causing fires, and keep lighters, matches and smoking materials away from flammable substances, including petrol, cleaning solvents and other flammable liquids²⁶. Lighters and matches stored on a windowsill above aerosols or cleaning fluids are a small hazard waiting to happen.

For a smoker with shaky hands or limited grip, the London Fire Brigade's carers' guidance makes a practical point: lighters are safer than matches, as a dropped match can start a fire²⁷. If you are choosing for an older person, that is worth knowing.

Devon and Somerset Fire and Rescue Service lists the warning signs that a smoker's home has a rising fire risk, useful if you check on a relative²²:

• Burns on carpets, furniture, bedding and clothing
• Evidence of smoking in bed
• Carelessly discarded cigarettes or matches
• Overflowing ashtrays or inappropriate ashtrays such as butter tubs
• Lighters or matches within the reach of children

If a child in your household has started playing with fire rather than just handling lighters, fire and rescue services run intervention schemes for exactly this: see children who set fires.

Smoking outside: the safest way to smoke if you still smoke

If you smoke and are not ready to quit, every fire service gives the same next-best step: smoke outside. Devon and Somerset Fire and Rescue Service says the best way to protect yourself and others from the dangers of smoking at home is to smoke outside²⁸. Warwickshire's guidance explains why it works: smoking outside eliminates the risk of accidental fires caused by dropped cigarettes or ashes²⁶. Somerset's household fire safety advice puts it in family terms: the best way to protect your family from the dangers of smoking inside the home is by choosing to smoke outside³.

Dorset and Wiltshire Fire and Rescue Service ranks the options in order: the best protection is to give up smoking altogether, or only ever smoke outside². Greater Manchester Fire and Rescue Service calls a smokefree home, meaning smoking outdoors, a real reduction in the risk of a fire in your property⁶.

Smoking outside only works if you do it properly:

• Take extra care to ensure cigarettes are put right out and disposed of safely²⁹
• Use a proper ashtray or a sturdy container outdoors, not a flowerpot or grass
• Never drop cigarette ends on the ground or throw them out of car windows²⁴
• Do not smoke near anything flammable, including petrol, solvents and dry vegetation²⁶

A cigarette end dropped into a plant pot is a common way for a "safe" outdoor habit to cause a fire anyway, because potting compost and dry roots smoulder well.

Discarded smoking materials outdoors: grass and heath fires

Cigarettes do not only cause house fires. The London Fire Brigade is direct about the outdoor risk: "Anything burning can start a grass fire. Cigarettes and barbecues are commonly to blame"²⁹. In warm, dry weather, grass, heathland and countryside can catch from a single end dropped from a car window or trodden into dry ground.

Dorset and Wiltshire Fire and Rescue Service, whose area includes large tracts of heathland, asks everyone to extinguish smoking materials properly, and not to throw cigarette ends on the ground or out of car windows, but to take their litter home²⁴. Their warning about underground smouldering is worth remembering: embers can hold heat below the surface for days before spreading to surface vegetation²⁴, so a fire that seems to have gone out may not have.

The practical rules for summer and dry spells:

• Extinguish smoking materials fully before you move on²⁴
• Take cigarette ends home rather than dropping them²⁴
• Never throw ends from a car window²⁴
• Treat dry grass, heath and woodland as flammable in warm weather²⁹

Stopping smoking: the surest prevention there is

Fire and rescue services are consistent on this. Greater Manchester Fire and Rescue Service: "The best way to prevent a smoking related fire at home is to stop smoking"⁵. The London Fire Brigade's carers' guidance says the same, and asks carers to start by encouraging the person they care for to quit²⁷. Mid and West Wales Fire and Rescue Service: "Giving up smoking is the best way to prevent a fire in your home due to smoking materials"¹⁵. Dorset and Wiltshire Fire and Rescue Service advises stopping smoking, alongside smoking outside².

This is fire safety advice, not health advice, but the two point the same way. Essex County Fire and Rescue Service notes that smoking is harmful to your health and is the most common cause of fatal fires¹⁶.

Help to quit is free on the NHS. Greater Manchester Fire and Rescue Service's own leaflet states that the best way to stop smoking is through a combination of medication and support, both of which are available on the NHS³⁰, and points smokers to makesmokinghistory.co.uk for local help⁵. Dorset and Wiltshire Fire and Rescue Service directs people to the NHS at www.nhs.uk/smokefree³¹, and the London Fire Brigade's guidance says to find help and advice on quitting on the NHS Smokefree website²⁷. If you care for someone who smokes, the London Fire Brigade asks you to talk to them about the risks relating to smoking and provide the associated fire safety advice²⁷.

Smoke alarms and the checks that protect a smoker's home

Every habit on this page reduces the chance of a fire starting. A smoke alarm is what protects you when one starts anyway, and for a smoker it is not optional. A working smoke alarm greatly reduces the risk of injury or death due to fire¹², and you are 4 times more likely to die in a domestic fire without one³.

Because smoking fires smoulder first, think about coverage as well as presence:

• Fit alarms on every level of your home and test them regularly
• In a large or multi-storey house, consider linked alarms, which all go off together when one detects a fire²⁵
• If anyone in the household is deaf or hard of hearing, specialist alarms exist: see smoke and CO alarms for deaf and hard of hearing people

Alongside alarms, the habits that close the loop are the ones above: stub out properly, empty ashtrays safely, keep lighters from children, and never smoke in bed. Our fire safety checklist for your home and bedtime fire safety checks pull these together into routines.

Caring for someone who smokes

If you look after a relative, neighbour or client who smokes, the fire risk is higher and the warning signs are visible. Devon and Somerset Fire and Rescue Service's home safety partnership guidance lists the signs to look for, from burns on furniture to overflowing ashtrays and lighters within children's reach²². The London Fire Brigade's carers' guidance asks carers to talk to the person about the risks and provide the fire safety advice²⁷, and to start by encouraging them to quit²⁷.

Where the person receives care, build fire safety into their daily routine. The fire and rescue service's advice is plain: never smoke in bed, and take extra care when smoking while tired, because it is easy to fall asleep with a cigarette burning and set the bed, sofa or clothes on fire²⁷. The consequences of getting this wrong are real: fires caused by smoking materials result in more deaths than any other type of fire in the UK³², and in Greater Manchester over 40% of accidental fire deaths are caused by smoking materials³².

Practical steps for a carer:

• Encourage the person to quit, or to smoke only outside²⁷
• Make sure fire risk is in the care plan, including bedding and emollient creams²⁷
• Swap matches for a lighter, since a dropped match can start a fire²⁷
• Check for burns on furniture, smoking in bed and overflowing ashtrays²²
• Confirm a working smoke alarm, and consider linked alarms in a larger home²⁵
