Gas barbecue buying guide

Updated: 23 October 2026

You are choosing a first or replacement gas barbecue for a UK garden, and the patio is smaller than the photos. Start with where you will cook and which valve the inlet accepts, then burner layout, then the price once hose and gas are in the basket. Peter F. edits DIY and tools at Products Compared. We read the amazon.co.uk listings in this comparison and public UK fire and gas guidance. We did not laboratory-test heat or rust. Prices are the shelf figures in GBP. A qualifying purchase can earn us a commission at no extra cost to you. The [gas barbecue comparison](/hub/grills-and-barbecues/gas-barbecue) lines the models up. These checks come first.

Start with where you will cook

A gas barbecue here is an outdoor LPG grill, and the site decides whether you should buy one. GOV.UK says never use a barbecue indoors, in a tent, under an awning or in a caravan. The cylinder stays outside, away from sun, frost, sheds and fences. London Fire Brigade says never use a barbecue on a balcony. A smaller grill does not turn that ban into a permit. On a patio the trolley stands in the open, with room to walk around the cylinder. Footprint on a patio you are allowed to use is on the small garden gas barbecue page.

Match the valve before the burner count

Patio trolleys on this shelf are propane-shaped, and many omit the hose and regulator. The CosmoGrill Original 4+1 (ASIN B06XY3QGY2, about £199.99, 4.4 from 1,036 reviews) lists the grill, not the hose. Calor's green Patio Gas is propane with a 27 mm clip-on, and Calor kits are marked 37 mbar. A Universal BBQ Kit does not prove this inlet's thread. Saved UK reviews of the Weber Q describe small canisters. The Campingaz Party Grill, about £96.01 and about 4.9 kg, takes a CV470 or R907 cartridge. If you own red propane or butane, read the propane or butane page before you assume one regulator covers both. Calor recommends propane outdoors because it vaporises at about −42°C, while butane fades near −2°C.

Layout, grate and conflicting power fields

Read the bullets when the fields disagree, and do not average them. Original 4+1 bullets say 7.2 kW while a wattage field says 9.3 kW. A 6+1 bullet says 12 kW total while a wattage field says 2,000 watts, and an area field says 77 cm² against a 77 × 42 cm grate. None of these listings print a BS EN 498 mark. A CosmoGrill 4+1 is about 126 cm across, and a 6+1 is about 149 cm wide. The Weber Q is one 2.93 kW burner and about 1,290 cm² of cast-iron grate.

Cover, steel and the true shelf price

A cover is weather kit, not a promise the cabinet stays bright. A 600D cover appears in two CosmoGrill titles, and UK reviews still describe rust under a cover. Stainless often means the burners or the handle. On this capture, entry models are about £89.99 to £96.01, mid trolleys about £169.99 to £219.99, and the upper shelf about £269.99 to £389.00. The Q 1200N with stand shows 5.0 from 4 reviews, against 4.4 from 1,036 on the Original. A thin sample is not the top pick. Who each model suits is on the best gas barbecue page.

Common questions

What should I check before I buy a gas barbecue?
Check the place, then the fuel fitting, then burner layout and grate, then the lid, grease tray and igniter, then what the cover and the word stainless actually cover, then the price after a hose and regulator. Cook outdoors only, clear of awnings, sheds and fences. If the hose is missing, the shelf price is not the cost of cooking this weekend.
How many burners do I need?
Match heat zones to the way you cook, not to a feeds-n-people line. A 2+1 is a small trolley. A 4+1 at about 126 cm is the mid-width trolley on this shelf. A 6+1 at about 149 cm needs a wide patio. A Weber Q has one 2.93 kW burner, so you cook in one zone and move food under the lid. We do not treat a headcount on the listing as a measured capacity.
Does a gas BBQ include a hose and regulator?
Often no. The CosmoGrill Original 4+1 on this shelf does not include the hose, and many patio trolleys expect you to add a 37 mbar kit and Patio Gas yourself. A Calor Universal BBQ Kit sold separately does not prove the inlet thread. Weber Q reviews describe small canisters, and the Campingaz Party Grill uses a CV470 or R907 cartridge. Read that listing's bullet before you assume the carton is complete.
Is a cover enough to stop rust?
No. A cover keeps rain off a cold, dry grill, and it does not stop rust on thin painted steel. UK reviews still report rust under a cover. Two CosmoGrill titles include a 600D cover, which is useful kit and still not a warranty. Stainless burners are not a stainless cabinet. A cover helps compared with a trolley left in the rain, and it is only a partial shield compared with a dry store.
Can I use a gas barbecue on a balcony?
No. London Fire Brigade says never use a barbecue on a balcony, and GOV.UK also rules out indoors, tents, awnings and caravans. A compact Weber Q or a cartridge camp grill does not make a balcony safe. If that is your only outdoor space, this is the wrong purchase. Use a patio or garden that is clear of fences, sheds and overhead fabric.
When is a portable a better buy than a trolley?
Choose a portable when you must carry it and you accept its fuel. The Weber Q 1100N is about 9.1 kg and UK reviews describe a small canister. The Campingaz Party Grill is about 4.9 kg on a CV470 or R907 cartridge. A trolley suits a grill that stays on a legal patio, though the hose may be extra. Neither makes a balcony safe, and 5.0 from 4 reviews does not outrank 4.4 from 1,036.
