Griddle plate for a gas BBQ

Updated: October 2026

Saturday breakfast is why a flat plate turns up on a gas barbecue built for bars. A griddle plate for a gas BBQ, in this amazon.co.uk set, is a stainless sheet on the grate you already own. The barbecue stays outdoors. The Products Compared editorial team read twelve grill-top listings on 15 October 2026. Shelf prices run from £43.99 to £104.99. Nothing was cooked in a lab. Eggs stop falling through the bars. Fat, flare-ups, and a plate that runs cooler than the lid gauge are the limits. The rows are the [stainless steel griddle comparison](/hub/grills-and-barbecues/stainless-steel-griddle). A qualifying purchase can earn a commission at no extra cost to you.

A plate on the grate, not a new barbecue

Every listing here is a grill-top plate described for a gas grill. The burners, hose, and regulator stay the ones in your barbecue. A freestanding gas plancha has its own burners and a much thicker plate. Its times and temperatures are not measurements of these ASINs. The plate is cookware. 304 on a title is a claim, and these files have no declaration of compliance. The appliance is the barbecue. GOV.UK guidance on assimilated Regulation 2016/426 covers gas type, pressure, and ventilation. BS EN 498:2012 type-tests outdoor LPG barbecues. A loose sheet sits outside that duty. Do not alter jets because the title says universal. The metal choice is the stainless steel vs carbon steel griddle page.

Fit

Large plates here are about 58 × 40 cm, mid plates about 45–51 cm wide, and smaller plates about 40 × 30 cm. A 58 cm plate on a compact kettle overhangs. Universal means the seller did not name your model. YIYAXIN's only UK review returned a 58 × 41 cm plate that was too big for a gas hob. Onlyfire B089VR7JVN prints 23 × 16 × 7 centimetres beside a 58.4 × 40.6 cm title. Treat 7 cm as wall height. That trap is on the stainless steel griddle plate buying guide.

Fat and flare-ups

On open bars, drips hit the burners and flare. On a plate, fat stays on the steel until a trough or a hole moves it. Most listings have a front trough. GriHero's UK reviews say the rear holes are small, a poor match for bacon. One kit review says less fat reached the flame. That is one cooker. A trough helps when you scrape toward it and the channel is big enough. It does not end flare-ups. A warped plate can tip the pool onto a burner. The WUDLEP file includes a UK weld failure, the surface parting from the subframe. Do not foil the burners or block the ventilation. The burners stay as the barbecue maker set them.

Heat, warp, and the lid thermometer

The lid gauge reads air in the hood. A shared Onlyfire review puts the barbecue near 380°C and the plate near 180°C. Those are the reviewer's readings. Preheat gradually and judge the steel. The QWORK note says the stated 1.2 mm plate warps while hot and eases back as it cools. GriHero buyers describe a warp after two uses, and the listing prints 1,472°F beside a bullet claiming up to 800°C. If the plate rocks or a weld has opened, take it off. Who should skip a thin plate is the best stainless steel griddle plate page.

Outdoors only

Cook outdoors, in the open. UK LPG guidance warns that carbon monoxide builds in tents and enclosed spaces, and it points to a regulator and a hose to BS 3212 type 2 or BS EN 1763 Class B. A closed-sided gazebo, a garage, a shed, or an enclosed balcony is that warning. The plate does not vent the cooker. Smell gas, see a cracked hose, or find the wrong regulator, and you stop. That is a gas-competent person. A new plate will not repair a hose. Washing and oiling are on the how to use a stainless steel griddle page.

Common questions

Can I put a plancha plate on my gas barbecue?
You can set a grill-top sheet on the grate, outdoors, of a gas barbecue you already own. All twelve listings here are that plate. A freestanding plancha is a different appliance. Leave the jets alone.
How do I know it will fit?
Measure the bars. Match about 58 × 40 cm, about 45–51 cm wide, or about 40 × 30 cm, and ignore a 7 cm line that is tray height. A Weber Go-Anywhere line and a Ninja FlexFlame line are single fits, not every barbecue in the shed.
Will it stop flare-ups?
A trough or drain can keep some fat off the flame if the fat actually leaves the plate. GriHero's rear holes are too small for bacon, so fat sits until it spills. A warp can tip the pool onto a burner. An end to flare-ups is not.
Can I use it on the side burner or the hob?
These wide sheets rarely fit a side ring or a hob. YIYAXIN's UK reviewer returned a 58 × 41 cm plate that would not work on a gas hob. Only GriHero claims induction, and the claim is untested here.
Can I cook under a gazebo or in the garage?
The gas barbecue belongs outdoors, in the open. UK LPG guidance warns about carbon monoxide in tents and enclosed spaces. A gazebo with the sides down, a garage, or a shed counts.
Why is the plate cooler than the lid thermometer?
The gauge reads hood air. Thin stainless does not hold that temperature. One shared Onlyfire review has about 380°C at the barbecue and about 180°C on the plate. Test the steel before the eggs.
When is the problem the barbecue, not the plate?
Gas smell, a cracked hose, a wrong regulator, or a split burner is the appliance. Stop, and use a gas-competent person. Warp, a small grease hole, and a bad fit are the sheet. Another plate will not mend a hose.
