Best BBQ griddle plate
Updated: 23 October 2026
You already own a gas barbecue, and the first page of UK results is trying to sell you a new flat-top cooker. Best BBQ griddle plate, for this job, means an insert or a pan that sits on the barbecue you have, not a Blackstone, a Ninja, or a Weber Slate. The highest stars in the twelve listings are a camp-stove plate. That is the wrong object if you are covering a gas cookbox. The [griddle plate comparison](/hub/grill-accessories/griddle-plate) holds the full table, with GBP prices from amazon.co.uk on 20 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

Best in this set for a gas barbecue
The top pick in this set for a gas barbecue you already own is the Onlyfire F-BGG8201-SS-EU, at about £59.99. The listing score is 74, the highest of the twelve, from 4.2 stars across 1,641 reviews, a grease trough and a stated 1.2 mm thickness. The bullet cooking surface is 45.5 by 27 cm. The details say 51 by 32 by 12.4 cm, and the title also says 47.2 cm, so measure the grates.
Several UK reviews say the sheet does not hold a sear unless the lid stays down. One puts the dome at about 380 degrees Celsius and the plate at about 180. The 1.2 mm figure is the seller’s bullet, not a measurement we made. Reviews also describe bending when the plate is hot. Preheat with the lid closed if you want this plate. If you need thick iron that stays hot with the lid open, skip it.
Best value if you also cook on a hob
The best value pick is the OVERMONT OM-Griddle-II at about £29.17, with 4.2 from 770 reviews and a listing score of 70. It is a reversible cast-iron pan. The details say 51.2 by 23.5 by 1.2 cm and 3.6 kg. A bullet says 17 inches by 9.2 inches, and the highlight says 20 by 9.2 inches. Those lengths do not match. Use 51.2 cm and measure the hob or the grates.
The dishwasher field is No. UK reviews say it rusts if it stays wet, so you dry it and oil it. The listing says induction as well as gas, oven and campfire. UK reviews dispute the induction claim. If your only cooker is induction, this is not a confirmed fit.
A Spirit owner should not treat either plate as the engineered insert. The Onlyfire reversible Spirit iron names front-control Spirit 300s and some 2025 four-burners. That fit list is on the Weber Spirit griddle plate page. Weber part 6790 is £189.99 on Weber UK and is not one of the twelve.
Leave these if they are the wrong job
The Campingaz 2214381 is 4.8 from 480 reviews at about £18.95, and it is the star line people quote. The bullet fits it to a Camp Bistro 3 and DLX, at about 24 by 22.4 cm. It does not fry a row of burgers across a gas barbecue. Two UK reviews report coating damage. Leave it unless the stove in the car boot is the cooker you own.
The Kordisen 0511 is 4.6 from 1,296 reviews at about £23.79, a 28 cm granite-coated hob pan. A best-BBQ list that crowns it has changed the question.
WUDLEP is 58 by 40 by 7 cm at about £44.99, with 3.9 from 11 reviews, and UK texts include a warp and a weld one buyer said was worse after three months. The honeycomb Onlyfire at about £99.99 is 4.5 from 14 reviews, and the usable UK sentence is a Ninja FlexFlame.
If the gas barbecue stays
Buy a gas plancha when you want burners built for a flat top. If the gas barbecue stays, use the Onlyfire sheet when you will cook lid-down, or the OVERMONT pan when you also want the hob and you will oil bare iron. A Spirit-shaped plate is a year check, and this page does not run it.
Common questions
What is the best plate if I already have a gas barbecue?
In this set it is the Onlyfire stainless plate at about £59.99, with a grease trough and a 1.2 mm bullet. Plan to preheat with the lid down. UK reviews say the surface stays cooler than the dome if you cook lid-open. It is a listing score, not a taste test.
Why not the 4.8-star Campingaz?
Because it is a camp-stove plate for a Camp Bistro 3 or DLX. The stars are real on amazon.co.uk. The job is breakfast for two on a suitcase stove, not a household gas barbecue. A high star line on the wrong size is still the wrong size.
Is the £29 reversible pan good enough?
It is good enough when you want smash burgers on a gas hob and a barbecue, and you will dry and oil cast iron. It is not good enough when you need a confirmed induction hob or a sheet that covers a four-burner.
Should I buy a Weber Slate instead?
Buy a Slate, or another complete gas plancha, when you want a flat top with its own burners and you are replacing the barbecue. Keep the insert if the gas barbecue is staying and you only want a flat surface on the grates you already light.
Which plate should a Spirit owner skip?
Skip a universal sheet if you need a plate shaped to the Spirit cookbox, and skip any Onlyfire Spirit title until you have checked the year and the knob position. The ceramic insert’s highlight says Spirit 400 while the title says Spirit 300.
What should I do if the sheet will not sear?
Close the lid and give the thin plate time to catch up with the dome. If you need a hard sear with the lid open, the value iron pan is the closer match in this set, with the rust care that comes with it. A cold thin sheet on full flame is also how warps start.
