The Best Gas BBQs with Cast Iron Grates (UK 2026)

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

Grate material quietly makes the biggest difference to how a gas barbecue cooks. Cast iron holds far more heat than thin steel, giving proper sear marks and even results. Here's what to look for and our top picks with cast iron grates.

Quick answer

Cast iron grates absorb and hold heat, so food sears properly instead of steaming, and the temperature doesn't crash when you put cold food on. Enamelled cast iron gives the same performance without the rust risk of bare iron and needs no seasoning. If you're choosing between two similar barbecues, the one with cast iron or thick enamelled grates will almost always cook better.

What to look for

Look for cast iron or enamelled cast iron rather than thin chrome-plated steel wire. Enamelled versions are easier to live with - no seasoning, no rust if the coating stays intact - so avoid chipping them with metal tools. Bare cast iron cooks superbly but needs oiling and drying to prevent rust. Check the grate weight if it's listed, as heft is a good proxy for heat retention.

How we pick

We rate these on grate quality and heat retention alongside burner control, build and value. Every pick has genuine cast iron or enamelled cast iron cooking grates.

Frequently asked questions

Are cast iron BBQ grates better?

Yes, for cooking performance - cast iron holds far more heat than thin steel, so it sears properly and keeps its temperature when cold food hits it. That means better crust and more even results. The trade-offs are weight and care: bare cast iron needs oiling to prevent rust, though enamelled cast iron avoids that while keeping the heat retention.

How do you clean cast iron BBQ grates?

Brush them while still warm after cooking, when residue lifts off most easily. For bare cast iron, dry them thoroughly and wipe with a little oil to prevent rust. Enamelled cast iron just needs brushing and drying - avoid harsh metal scrapers that could chip the enamel and expose the iron underneath. Never leave either sitting damp.

Bottom line

Our top pick is the Char-Broil Gas2Coal 330 Hybrid (our score 9.6/10) - A practical gas barbecue (3 burners + 1 side burner, hybrid gas + charcoal) for outdoor cooking..
