What a gas BBQ with side burner is

In this UK set, a gas BBQ with a side burner is a wheeled outdoor cart: main grill burners plus a separate gas ring for a pan. The ring sits beside the hood, usually under its own lid, for sauces, onions, or a kettle. A fold-down shelf only holds tongs. Gardeners' World draws the same line: a side burner cooks; a side table stores. None of these seven rows prints BS EN 498 or BS EN 484, so do not claim compliance from a shopping comparison. If the text only says side tables, you are on the wrong type. The side burner vs side table page keeps that split.

Check the side ring first

Read the side-burner count or a bullet that names side-burner kilowatts. Kept listings print a count of 1, or a 2.1 kW or 2.5 kW side burner. 4+1 is four mains plus the ring, 6+1 is six mains plus the ring, and 2+1 is two mains plus the ring. The plus-one is never a shelf. A Weber Q 1200N style listing with side tables and one main burner fails this check. So does any row with no side-burner count. If the ring is not printed, leave the listing. Four mains suit most households cooking for about six. Six mains are the party layout.

Hose, pressure, and bottle size

None of the seven included-components lines names a hose. Campfire bullets say the regulator and hose are not included, and UK reviews say buyers purchased fittings before first light. Treat about £20 as a normal extra unless a listing packs them. Liquid Gas UK Guidance Sheet 39 puts butane around 28–30 mbar and propane at 37 mbar, with new regulators marked BS EN 16129. Patio gas is the green propane cylinder with a 27 mm clip-on. Count the side ring when you choose bottle size. Site the cart on level ground outdoors, clear of fences, sheds, awnings, and caravans. London Fire Brigade advises against balconies. The NHS says not indoors or in a tent.

Heat figures you must not merge

Quote one printed heat figure. BROILUCK shows 8,700 W on both power fields. Campfire bullets say four 11.2 kW burners plus a 2.5 kW side burner, while the wattage field repeats 11.2 kW. That field is one burner, not a total of five. CosmoGrill Original bullets say four 7.2 kW mains plus a 2.1 kW side burner, and the wattage field says 9.3 kW. Model 93411 bullets say four 2.5 kW mains plus a 2.5 kW side burner. Model 93416 can be read as 12 kW on six mains plus 2.5 kW on the side, with a material line at 14.5 kW and wattage fields at 2,000 W. Do not multiply 11.2 kW by four, and do not treat 2,000 W as the 6+1 party total.

Matching people and price bands

Gardeners' World puts at least four main burners against a household that regularly feeds six or more. The side ring is not an extra main for that count. A small household often lands on the about £89.99 2+1 if ignition complaints are acceptable, or the CosmoGrill Original at about £199.99 for the longer review file. A party cart with two builders points at a 6+1 near £290 to £300. On model 93416 the cover is a title difference, not a different burner layout, and it does not replace a soap-tested hose. Match one job to one listing on best gas BBQ with side burner.

Common questions

What does 4+1 or 6+1 mean on a gas BBQ?
Four or six is the main-burner count under the hood. The +1 is a separate side gas ring for a pan. It is not a side shelf. If the listing only says side tables, it is a different product type from the seven carts in this comparison.
Is the hose and regulator in the box on these amazon.co.uk listings?
Not on the seven included-components lines in this set. Campfire bullets state the regulator and hose are excluded. Plan to buy fittings that match your cylinder pressure before first light.
Which patio gas bottle size for a 4+1 or 6+1?
Published guidance, not a lab result on these listings: Calor points 13 kg Patio Gas at four or more burners. Gardeners' World suggests at least 10 kg once you are at five or more burners counting the side ring. A 5 kg bottle is aimed at smaller three-burner jobs.
Which kilowatt figure may I quote when the bullet and the field disagree?
Quote one printed line and say which. Do not add Campfire's 11.2 kW four times, and do not treat a 2,000 W field as the CosmoGrill 6+1 party total. Conflicting fields stay visible. They are not merged here.
When should I stop and call a Gas Safe engineer?
If you want a permanent pipe rather than a cylinder hose, that is Gas Safe work. If a joint still bubbles after a soap test, if you smell gas and the side burner will not light, or if anyone may have carbon monoxide poisoning, stop cooking and get help. The gas emergency line is 0800 111 999. Suspected carbon monoxide is NHS 111 or 999.
