You have a small charcoal tray, a bag of fuel, and a picnic table that was not built as a hearth. This is how to use a portable charcoal BBQ at that scale, following the England fire-safety leaflet updated on 25 May 2022 and the Scottish Fire and Rescue Service guide updated on 24 June 2024. Which tray you bought is on the [portable grill comparison](/hub/portable-grills/portable-grill).

Where this grill is allowed to burn
Light it outdoors, on a stable heat-proof surface. The England leaflet says never indoors, in a tent, under an awning or in a caravan. Devon and Somerset Fire and Rescue Service repeats that ban. A modern tent can reach dangerous carbon monoxide levels in minutes, so a detector in the canvas is not permission to cook there. If rain starts, wait it out.
Norfolk County Council says never light a barbecue on a balcony in a block of flats. Avon Fire and Rescue Service, on 3 June 2024, adds a conservatory or a greenhouse. One iHomara review says the underside warped a table, so a plastic picnic top is the wrong stand. The iHomara's indoor-use bullet does not override that. In dry open country the Scottish Outdoor Access Code prefers a stove to an open fire.
How much charcoal, and how to light it
The England leaflet's guide is about 5 cm of charcoal, and not more. On a book-sized tray that depth can already be too much. The Charmline bullets say below half the tray, so on a small folder stay under both limits. A 5 cm layer is a ceiling for a normal barbecue, not a target you fill because extra people have arrived.
Do not use petrol, paraffin or white spirit. Use a lighting block or chimney starter on cold coals only, and leave the vents clear. The AGM and Minxchen listings mention five side vents, and fuel piled over those holes smokes instead of cooking. Wait until the coals glow and the starter has burnt off. If the fire sulks, do not add starter to flames. Let it die back and begin again from cold.
While it is lit
Keep the tray where you lit it, and stay with it. Two or three portions is the honest load when a title says 1-3 people. An AGM line of 5-7 people does not create a larger firebox. If the table edge scorches, the stand is too thin or the charcoal is too deep.
Kizmyee reviews mention sharp edges even during assembly, so assume a hot rim can cut. Use tongs. Wind hits a lidless tray harder than a kettle, so aim the short side before you light, not by twisting a lit pan. If the fire spreads beyond a bucket you can safely use, call 999. Someone overcome by fumes, or a tent involved, is the same call.
Cooling, ash and the car
The food can be done while the fire is not. Devon and Somerset say a cooling barbecue should not go into a car or a tent, because coals stay hot for hours. Scottish Fire and Rescue Service wants ash cold to the touch. The England leaflet says bare soil, not a plastic bin or a wheelie bin. Fold the tray only once it is cold, or it can mark the boot and relight.
Wash and dry the grate before you pack it, or rust finds the mesh. A stainless bullet and a material field sometimes disagree, which is why the metal line is a claim rather than a rust-proof promise.
Common questions
How do I light a portable charcoal grill?
Set the tray outdoors on a heat-proof stand, add a small charcoal load, and light it with a proper starter on cold coals. Keep the layer at or below about 5 cm, and below half the tray if the product says so, as the Charmline bullets do. Leave the vents clear, and wait until the starter has burnt off before food goes on. Do not use petrol, paraffin or white spirit, and do not light it in a tent or awning.
How much charcoal is enough on a small tray?
Enough is a shallow layer the pan can hold without spilling. The England leaflet of 25 May 2022 says about 5 cm and not more. On a small folder, half a tray can be tighter, which is what the Charmline listing tells you. These files do not weigh a fuel load in kilograms. If the food does not fit, cook in rounds rather than adding charcoal.
Can I use it in a tent or awning if the listing says indoor?
No. UK fire services say never in a tent, under an awning, in a caravan, or indoors. The iHomara bullets mention indoor and outdoor use. That line is not a clearance. Carbon monoxide can reach dangerous levels in a modern tent in minutes, including while the tray is only cooling. A smoke alarm in the canvas does not change the ban.
How do I put the coals out?
Stop adding fuel, let the coals burn down, and leave the tray until the ash is cold to the touch, which can take hours. Do not pack a cooling grill into a car or a tent. Ashes go on bare soil or into a metal point the site provides, not into a plastic bin. If the fire spreads beyond a bucket, call 999.
Can the ash go in the wheelie bin once it looks grey?
No. Grey on top does not mean cold underneath, and a plastic wheelie bin is the wrong place even later. The England leaflet says bare soil, not a plastic bin. Scottish Fire and Rescue Service says cold to the touch. If you would not comfortably touch it, it is not ready. A melted bin is how a finished barbecue starts a second fire.
Why is the table scorched underneath?
The base of a thin tray radiates heat downwards, especially if the charcoal is heaped. One iHomara review says the underside warped a table. Use paving or a stand that can take heat, and keep the fuel shallow. Do not slide the lit grill onto a wooden bench to finish. Scorching means the surface was wrong.
