These rules are jurisdictional. Each one names the authority it comes from and the territories it applies in. Where BBQHQ holds no rule for your territory, it shows you nothing rather than showing you somebody else’s.
What the rules say
UK: do not use a barbecue on a balcony
criticalLondon Fire Brigade · GB · last verified 2026-08-13 · review due 2027-02-13
Do not use a barbecue on a balcony. Flames, sparks and hot embers can start a fire that spreads quickly to other parts of the building.
The hazard is not primarily to the person cooking. A balcony fire reaches neighbouring balconies and the building's exterior, and the people at risk are the ones who did not light it. Many leases and building rules prohibit it separately, and a manufacturer clearance requirement of three feet to rails — as SharkNinja specifies for its electric grill — is not achievable on most balconies in any case.
Where this comes from
London Fire Brigade instructs that a barbecue must not be used on a balcony, because flames, sparks and hot embers can start a fire that spreads quickly through the building.
Well supported
London Fire Brigade — States this directly
“Don't use a BBQ on a balcony. Flames, sparks and hot embers can cause a fire and spread quickly to other parts of the building.”
- Where it applies:
- A London fire authority. The reasoning is general but the instruction is regional operational guidance, not global law.
- Why it happens:
- The hazard is spread to the building, not to the cook.
- What it covers:
- Stated for barbecues generally, without distinguishing fuel type.

UK: where to stand a barbecue, and never leave it
significantLondon Fire Brigade · GB · last verified 2026-08-13 · review due 2027-02-13
Stand a barbecue on level ground and not on decking, well away from anything that could catch fire — sheds, fences, trees. Never leave it unattended while it is lit.
Decking is named explicitly by London Fire Brigade rather than implied. It is combustible, it is usually right against the house, and it is where most domestic barbecues end up because it is the flat bit of the garden.
Where this comes from
A barbecue should stand on level ground and not on decking, well clear of sheds, fences and trees, and must never be left unattended while lit.
Well supported
London Fire Brigade — States this directly
“Position your BBQ on level ground (not decking) and keep it well away from anything that may catch fire such as sheds, fences or trees.”
- Decking is named explicitly as a surface to avoid, not merely as an example.
- Where it applies:
- London, as regional operational guidance.

UK: putting out and disposing of coals and ash
criticalLondon Fire Brigade · GB · last verified 2026-08-13 · review due 2027-02-13
Let the barbecue cool and make sure it is properly out before disposing of coals or ash, and never put them in a bin while they are still warm. Smouldering ashes give off carbon monoxide and stay a fire risk for hours after cooking has finished.
This rule spans two hazards at once, which is why it is easy to under-rate: the ash is still producing carbon monoxide, so it must not come indoors, AND it is still capable of starting a fire, so it must not go in a plastic bin. The ground under a disposable barbecue also stays hot enough to burn somebody long after the barbecue has been lifted off it.
Where this comes from
Coals and ash must be fully extinguished and cold before disposal or storage. Smouldering ashes give off carbon monoxide and remain a fire risk for hours after cooking has finished.
Well supported
London Fire Brigade — States this directly
“After cooking, let it cool and make sure it is properly out – smouldering ashes can give off dangerous carbon monoxide fumes and can be fatal.”
- An independent authority reaching the same conclusion as the Public Health Agency by a different route — a fire service rather than a public-health body.

A barbecue continues to produce carbon monoxide as it cools. A barbecue that is no longer flaming is still lethal in an enclosed space.
Well established
Public Health Agency (Northern Ireland) — States this directly
“Even a cooling barbecue gives off plenty of poisonous carbon monoxide”
- Why it happens:
- Incomplete combustion continues while fuel is still smouldering.
- Combustion chemistry, so it does not vary by jurisdiction — unlike the food rules.

Public Health Agency (Northern Ireland) — States this directly
A barbecue should never be taken into a tent, awning, caravan or motorhome, including when it is only cooling.
- What it covers:
- Applies to charcoal and other combustion barbecues.
- Carbon monoxide is colourless and odourless, so there is no warning before symptoms.

UK: lighting a barbecue, and local bans on disposables
significantLondon Fire Brigade · GB · last verified 2026-08-13 · review due 2027-02-13
Never light a barbecue in an enclosed space, and do not use accelerants to get it going. Check local rules before taking a disposable barbecue to a park or open space — many London parks have banned them because of grass-fire risk.
The accelerant instruction is about the moment of ignition rather than the cook: petrol and similar liquids flash rather than burn, and the person leaning over the barbecue is the one who gets hurt. The disposable-barbecue point is deliberately phrased as 'check local rules' because it IS local byelaw, and BBQHQ does not turn one authority's park regulations into a national prohibition.
Where this comes from
A barbecue must never be lit in an enclosed space, and accelerants must not be used to get it going. Many London parks and open spaces have banned disposable barbecues because of grass-fire risk in hot weather.
Well supported
London Fire Brigade — States this directly
“Never light a barbecue in an enclosed space and don't use accelerants to get it going.”
- The disposable-barbecue ban is a local byelaw matter, explicitly London's parks. Recorded as an example of regional regulation, not a universal rule.
