The Best 3-Burner Gas BBQs (UK 2026)

By the Grill and Grate editorial team · Updated 2026 · How we test & score

A 3-burner gas BBQ suits most households well - enough space for a family meal without the footprint of a big multi-burner grill. Here's what to look for and our top 3-burner picks.

Quick answer

Three burners give you a practical cooking area plus enough control to run a hot zone and a cooler one, which covers most grilling. Options from Campingaz, Fire Mountain, Outsunny and George Foreman are strong here. Look for individually controlled burners, decent grates, a lid with a thermometer, and a footprint that fits your patio with room to work around it.

What to look for

Check each burner is separately controllable, so you can turn one off for indirect cooking. Grate material matters - cast iron and thick enamelled steel outperform thin chrome plate for heat retention and searing. A lid with a thermometer lets you cook with it closed, which is essential for thicker cuts. Consider whether you want a side burner, and check the assembled width fits your space.

Frequently asked questions

Is a 3-burner gas BBQ enough?

For most households, yes - three burners comfortably cook for around four to six people and still allow zone cooking, with one burner off for indirect heat. It's a sensible middle ground: more capacity and control than a 2-burner, without the width and cost of a 4 or 5-burner. If you regularly host large gatherings, size up; otherwise three is plenty.

What is zone cooking on a gas BBQ?

Zone cooking means running your burners at different levels to create hot and cooler areas. You sear food over the hot zone, then move it to the cooler side (or a burner turned off) to cook through with the lid down - indirect heat. It's how you get chicken cooked through without a burnt outside, and it's why individually controlled burners matter more than raw power.

Bottom line

Our top pick is the Fire Mountain Sierra 3 Burner (our score 9.5/10) - A practical gas barbecue (3-burner) for outdoor cooking..
