The Best Gas BBQs Under £300 (UK 2026)
You don't need to spend a fortune for a capable gas barbecue - plenty of good grills sit under £300. Here's what to look for and our top value gas BBQ picks.
Quick answer
Under £300 you can get a solid 2 to 4-burner from CosmoGrill, Outsunny, VonHaus, Fire Mountain or George Foreman. At this level, prioritise the right burner count, a lid (ideally with a thermometer) and the best grates you can get, over extras like rotisseries. Expect thinner steel than premium models, so a cover and winter storage matter even more for making it last.
What to look for
On a budget, put your money into the essentials: enough burners for your household, individual burner controls for zone cooking, and a lid so you can cook more than just burgers. Grate material is where cheaper barbecues most often cut corners - cast iron or enamelled steel is worth seeking out over thin chrome plate. Read owner feedback on build and rust, and plan to cover it, as that's what determines whether it lasts one season or five.
How we pick
We rate value barbecues on cooking performance for the money, burner count, grates and durability. Every pick is a genuine, good-value gas barbecue.

Frequently asked questions
Are cheap gas BBQs any good?
A well-chosen budget gas BBQ cooks perfectly well - the burners and controls on value models are usually fine. Where they differ from premium grills is materials: thinner steel, lighter grates and less rust resistance, which affects how long it lasts rather than how it cooks. Keep it covered and stored dry over winter and an affordable barbecue can serve you for several seasons.
What should I prioritise on a budget gas BBQ?
Put your money into burner count for your household, individually controlled burners so you can cook indirectly, a lid with a thermometer, and the heaviest grates you can get. Skip extras like rotisseries and elaborate shelving. Then buy a cover - protecting a budget barbecue from rain is the single biggest thing you can do to extend its life.
