The best stainless steel gas BBQs, compared.
Top pick: CosmoGrill Platinum rotisserie Best value: Onlyfire 2-burner – Best value in this set: about £189.49, score 77, 4.3 from 49 ratings, stated 4.7 kW. No regulator is named in the box. Updated 22.10.2026.
A stainless steel gas BBQ is an outdoor LPG grill whose burners, hood, cart, or cabinet panels are sold as stainless steel. In the UK you buy one for a patio or a garden when you want gas heat that rinses cleaner than bare mild steel. The label is not a promise that every panel is the same grade, and stainless is not rust-proof in salt or under a wet cover. You tell a suitable stainless steel gas BBQ by the steel that is named, the gas fitting, and whether the burner count agrees with the stated kilowatts. Patio propane is often about 37 mbar, and butane about 28 to 30 mbar. A cartridge cylinder needs its own screw-on. A tabletop suits a trip. A wheeled trolley suits a garden party. GOV.UK says never light a barbecue indoors, in a tent, under an awning, or in a caravan, and turn the cylinder off first after cooking. What the steel covers, and how you match the regulator, is in the [stainless steel gas BBQ buying guide](/hub/grills-and-barbecues/stainless-steel-gas-bbq/sub/stainless-steel-gas-bbq-buying-guide).

Question 1 of 2
Where will you cook?
This CosmoGrill Platinum bundle is the dearest here at £676.16, listed at 115 x 160 x 50 centimetres and 51.5 kg, with a 600D cover and a steel motorised rotisserie the listing describes for small to medium chickens. The bullet describes eight stainless burners at 27.7 kW and heat over 350°C; the power specification says 27 kW, and the burner line reads eight main plus one side. The material line says metal, with a stainless frame, so the stainless wording sits in the title and the frame. Cast-iron grates, a liftable centre, an infrared sear zone, a grease tray, and a 37 mbar propane regulator and hose are named. The score is 5.0 from 11 amazon.co.uk ratings, which is 80 once the thin sample is counted. Seven sampled UK review texts praise the cover, stainless build, the sear or rear burner, and value, and they still mention build quality, assembly, dents, the regulator, and ignition.
Pros
Cons
Best for: You want the rotisserie kit and the cover with this wide trolley, and you accept that 11 ratings is a thin base.
Less suitable: You want the material line to say stainless, or a score backed by more than a handful of reviews at £676.16.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named. The power line also says 27 kW beside a 27.7 kW bullet. The hose does not settle that clash, and it is not a butane fitting.
Is the body stainless steel?
The material line says metal. The frame is stainless steel. The title uses stainless. Read those three lines together rather than the title alone. A 600D cover and a rotisserie kit are named.
How strong is the review sample?
5.0 out of 5 from 11 amazon.co.uk ratings. Perfect stars on 11 ratings do not outrank 4.5 from 366. It is a shopper score, not a lab test.
This covered CosmoGrill Platinum is listed at 50 x 160 x 115 centimetres and 51.5 kg, at £621.99, with a 600D cover. The bullet describes eight stainless burners at a combined 27.7 kW and heat over 350°C, while the burner specification says six main plus one side, so the 6+2 title and the burner count disagree. Cast-iron grates with a liftable centre, an infrared sear zone, a rotisserie back burner, LED dials, a grease tray, and a 37 mbar propane regulator and hose are named; ignition type is not. It has the fuller Platinum sample: 4.6 from 45 amazon.co.uk ratings, score 81. In 28 sampled UK review texts, praise covers stainless build, heat, assembly, the sear or rear burner, and moving it on the wheels. Those texts also report difficult assembly, build concerns, regulator trouble, dents, ignition faults, and grease fires. A further clash on the same listing: one line marks it as built-in, and the description is a free-standing trolley with four lockable castors.
Pros
Cons
Best for: You want the wide Platinum with a cover in the box, and you will count the knobs in the photos before you pay £621.99.
Less suitable: You need one clear burner count, and a listing that describes this as a free-standing trolley throughout.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named in the box. That is the usual patio-propane pressure. It is not a butane regulator, and it does not by itself prove the grill will hold 27.7 kW on every UK cylinder.
Is the body stainless steel?
Material and frame on the listing are stainless steel. The grates are cast iron, and the sear zone is infrared. Count the burners in the photos: the bullet says eight, and the specification says six main plus one side.
How strong is the review sample?
4.6 out of 5 from 45 amazon.co.uk ratings. That is a shopper score, not a lab test. The 28 sampled texts praise heat and still mention assembly, dents, and ignition faults.
The CosmoGrill Platinum 4+2 on this listing is a 43 kg stainless trolley, 55 x 140 x 115 centimetres, priced at £502.55. Four 3.5 kW main burners, a 3.2 kW ceramic back burner, and a 4 kW ceramic searer are the stated layout; the bullet sums them to 21.2 kW and claims up to 370°C, while the power specification says 20.7 kW. Piezo ignition, a lid gauge, a tempered-glass viewing window, four-piece cast-iron grates, a grease tray, and a 37 mbar propane regulator and hose are named. A cover is not named on the listing. The score is 4.6 from 36 amazon.co.uk ratings, which is 80 on the method used here. In 20 sampled UK review texts the repeated praise is heat and value, and the repeated complaints are assembly, transit dents, ignition, the regulator, and grease fires or overheating.
Pros
Cons
Best for: You want a stainless 4+2 trolley with a sear zone and a viewing window, and you will add a cover yourself.
Less suitable: You want the cover in the box, or a rating count in the hundreds before you spend £502.55.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named among the included parts. Match that to a propane or patio-gas cylinder. Butane at about 28 to 30 mbar needs a different regulator.
Is the body stainless steel?
Material and frame on the listing are stainless steel. The grates are cast iron, and the sear and back burners are described as ceramic. A cover is not named.
How strong is the review sample?
4.6 out of 5 from 36 amazon.co.uk ratings. That is a shopper score, not a lab test, and 36 ratings is a modest base at £502.55.
The CosmoGrill Pro Deluxe is a garden trolley listed at 55 x 149 x 110 centimetres and 39 kg, with six main burners plus a side burner, and it carries the largest rating count here: 4.5 from 366 amazon.co.uk ratings, at £299.99. Piezo ignition, a lid gauge, enamelled grates, a 77 x 42 cm cooking area, a full-length warming rack, a side table, two castors, and a 600D cover are all named. One bullet gives the six burners 12 kW and the side burner 2.5 kW; the power specification lists 12,000 BTU and 2,000 W, so the heat numbers on the listing do not agree. In 50 sampled UK review texts, praise centres on heat, the cover, value, assembly, and rolling it into place. Those texts also raise regulator or hose trouble, difficult instructions, dents, rust, and grease fires. The material line says stainless steel and the frame is aluminium, a bullet describes powdered steel, and another line says the regulator and hose are not included even though a 37 mbar propane set is also listed. Score 89 is the highest in this set, so it is the top pick if you will check the steel finish and the gas fittings when it arrives.
Pros
Cons
Best for: You want a six-burner garden trolley with a cover, and you will check the steel finish and the gas fittings when it arrives.
Less suitable: You need an unambiguous all-stainless cabinet, a ceramic sear burner, or a barbecue that arrives assembled.
Specifications
Common questions
What gas regulator does the listing describe?
One line names a 37 mbar propane regulator and hose. Another says the regulator and hose are not included. Treat that as a clash and check the carton against the cylinder you will use.
Is the body stainless steel?
The material line says stainless steel and the frame is aluminium. A bullet also describes powdered steel, and the grates are enamelled. Do not read the title as one grade throughout.
How strong is the review sample?
4.5 out of 5 from 366 amazon.co.uk ratings, the largest count in this set. That is a shopper score, not a lab cook. Sampled texts still mention dents, rust, and grease fires.
The Onlyfire two-burner is a tabletop gas barbecue at 52.7 x 35 x 36.7 centimetres and 14.4 kg, with a stated 4.7 kW (4,700 W, 15,917 BTU) across two burners. The listing specifies an 18 x 14 inch stainless grate, electric ignition, a lid gauge, a removable grease tray, folding legs, a carry handle, a locking lid, and a cover. It is listed at £189.49 with 4.3 from 49 amazon.co.uk ratings. In 30 sampled UK review texts, the repeated praise is heat, a sturdy stainless feel, easy moving, straightforward assembly, and value. The same texts flag regulator or hose trouble, transit dents, ignition faults, grease fires or overheating, and rust. No regulator is named in the box, and some Onlyfire review text in this set describes a different burner count from the title, so the shared 49-rating line needs a check against this two-burner. It is the best value in this set: the lowest shelf price with that 49-rating sample, score 77, if you already own a regulator.
Pros
Cons
Best for: You want a compact two-burner for a table or a trip, and you already own a regulator for your cylinder.
Less suitable: You need a wheeled garden cabinet for a crowd, or a hose and regulator supplied in the carton.
Specifications
Common questions
What gas regulator does it need?
The listing does not name a regulator in the box. Match propane at about 37 mbar, or butane at about 28 to 30 mbar, to the cylinder you will use.
Is the body stainless steel?
Material and frame on the listing are stainless steel. Read the bullets for powdered or enamelled parts. The grate is described as an 18 x 14 inch stainless piece.
How strong is the review sample?
4.3 out of 5 from 49 amazon.co.uk ratings. That count matches the three-burner listing, and some review text describes another burner count. It is a shopper score, not a lab test.
The Onlyfire three-burner is the larger portable: 60 x 35.5 x 36.5 centimetres, 15 kg, and a stated 7 kW across three burners that the listing says can run together or one at a time. It quotes a 22 x 13 inch grate, electric ignition, a lid gauge, a removable grease tray, folding legs, a carry handle, and a cover, at £229.99. The published score is 4.3 from 49 amazon.co.uk ratings, the same count as the two-burner, and the method score is 77. Thirty sampled UK review texts praise heat, stainless build, portability, assembly, and value. Complaints in those texts cluster on the regulator or cylinder connection, dents, ignition, grease fires or overheating, and rust. The listing does not name a regulator in the box, so a hose still has to be matched to the cylinder, propane at about 37 mbar or butane at about 28 to 30 mbar.
Pros
Cons
Best for: You want a three-burner you can fold and carry, and you will supply the UK regulator yourself.
Less suitable: You want a side burner and a cabinet, or gas fittings already in the carton.

Is the body stainless steel?

This CosmoGrill Platinum listing adds a weatherproof cover to the 4+2 layout: four 3.5 kW burners, a 3.2 kW ceramic back burner described as a rotisserie burner, and a 4 kW ceramic searer, on a 43 kg body of 55 x 140 x 115 centimetres at £539.10. The bullet's combined output is 21.2 kW with a claimed 370°C, against a 20.7 kW power specification. A 600D cover, cast-iron grates, a grease tray, and a 37 mbar propane regulator and hose are named; ignition type is not. The bullets also mention a tempered-glass window, so check that window on the photos of this model. The score is 4.3 from 24 amazon.co.uk ratings, which is 74 on this method, and only five UK review texts were sampled. Those texts praise heat, assembly, and stainless build, and they also report difficult assembly and regulator or cylinder trouble.
Pros
Cons
Best for: You want this 4+2 layout with the cover already packed, and you are content to judge it on 24 ratings.
Less suitable: You need a long review history, or a grill whose listing counts six main burners.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named, with a weatherproof cover. Ignition type is not stated. Regulator or cylinder trouble still appears in the five sampled review texts.
Is the body stainless steel?
Material and frame on the listing are stainless steel. The bullets mention a tempered-glass window, so confirm that window on the photos of this model rather than on a sibling listing.
How strong is the review sample?
4.3 out of 5 from 24 amazon.co.uk ratings. Only five UK review texts were grouped. That is a shopper score, not a lab test.
The Onlyfire with the folding trolley is a three-burner grill at a stated 7 kW, measuring 87.5 x 35.5 x 97 centimetres and weighing 20.5 kg, with a 22 x 13 inch grate. Electric ignition, a lid gauge, and a side rack for plates are named, and grease is described as running to a collector at the back. The regulator line is written for a 1 lb bottle, with an extra connector if a larger tank is used, which sits awkwardly against a standard UK patio cylinder. A cover is not confirmed. The score is 4.3 from 18 amazon.co.uk ratings, which is 73 on this method, and only seven UK review texts were sampled. Those texts praise heat, stainless build, moving it, and value at £279.99, while the recurring faults are rust and build quality.
Pros
Cons
Best for: You want a slim three-burner trolley for a patio or a trip, and you can match the regulator to your own cylinder.
Less suitable: You want a confirmed weather cover, or you expected the included regulator to suit a standard UK patio cylinder.
Specifications
Common questions

The regulator line is written for a 1 lb bottle, with an extra connector if a larger tank is used. That is not a standard UK patio cylinder. Match propane at about 37 mbar or butane at about 28 to 30 mbar yourself if the included fitting does not suit the bottle.
Is the body stainless steel?
Material and frame on the listing are stainless steel. It weighs 20.5 kg on a folding trolley. A weather cover is not confirmed, and rust is a recurring note in the sampled texts.

This CosmoGrill Platinum 6+2 is the wide trolley at 50 x 160 x 115 centimetres and 51.5 kg, priced at £599.99. The listing describes eight stainless burners at a combined 27.7 kW, individually controlled, with a claimed temperature over 350°C, a rotisserie back burner, an infrared side sear zone, and LED-lit dials. Cast-iron grates have a removable centre for a pizza stone or pan, and a grease tray plus a 37 mbar propane regulator and hose are named. The materials named are alloy steel, cast iron, and ceramic, with a stainless frame. No cover is named, and ignition type is blank. The score is 4.2 from 16 amazon.co.uk ratings, which is 71 on this method; four sampled UK review texts praise a sturdy build, and the criticisms are assembly and build quality.
Pros
Cons
Best for: You want the 160 cm, 27.7 kW Platinum layout for a garden, and you will buy a cover separately.
Less suitable: You need a listing that calls the body stainless, or a review sample larger than 16 ratings.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named. Ignition type is blank. The stated heat is 27.7 kW on eight burners in the bullet. The hose does not guarantee that output on a small cylinder.
Is the body stainless steel?
The material line lists alloy steel, cast iron, and ceramic. The frame is stainless steel. A cover is not named. Do not read the 6+2 title as a full stainless cabinet.
How strong is the review sample?
4.2 out of 5 from 16 amazon.co.uk ratings. Four sampled texts praise a sturdy build and criticise assembly. That is a shopper score, not a lab test.
The CosmoGrill Yamara 4+2 is a 48 kg stainless trolley, 55 x 140 x 117 centimetres, at £539.99, with four 3.5 kW burners, a 3.2 kW ceramic back burner, and a 4 kW ceramic searer. On this listing the power specification matches the bullet at 21.2 kW, alongside a claimed 370°C, a tempered-glass window, cast-iron grates, a grease tray, and a 37 mbar propane regulator and hose. The title also names bamboo storage, and the included parts are a lid, a thermometer, and a tool holder. A cover is not named, and ignition type is blank. The score is 4.2 from nine amazon.co.uk ratings, which is 69 on this method. Only four UK review texts were available to group: they mention straightforward assembly, the sear zone or window, and heat, and they also cite ignition faults, regulator or hose trouble, assembly difficulty, and after-sales that are hard to reach.
Pros
Cons
Best for: You want the Yamara window, sear zone, and bamboo storage, and you will read the latest reviews because nine ratings is a small base.
Less suitable: You want a cover in the box, or dozens of UK reviews behind a £539.99 trolley.
Specifications
Common questions
What gas regulator does the listing describe?
A 37 mbar propane regulator and hose are named. Ignition type is blank, and ignition faults are a recurring note in the four sampled texts. A cover is not named.
Is the body stainless steel?
Material and frame on the listing are stainless steel. The title also names bamboo storage, a tempered-glass window, and cast-iron grates. The included parts listed are a lid, a thermometer, and a tool holder.
How strong is the review sample?
4.2 out of 5 from nine amazon.co.uk ratings. Four UK texts mention assembly, the window or sear zone, ignition faults, and after-sales that are hard to reach. That sample is too small to rank a £539.99 trolley on stars alone.
Scores on the ten amazon.co.uk stainless steel gas BBQs kept in this set run from 0 to 100. Stars contribute up to 70: the star line divided by five, times 70, rounded. Review volume contributes up to 30: log10 of the rating count, times 10, capped at 30. No feature bonus was added after that base. The top pick is the highest score. The best value is the lowest shelf price among the keepers with a usable review sample, not the second-highest score. A star line is not a BS EN 498 result. None of these rows was cooked in a lab. The weights below sum to 100.
Amazon stars
70%Up to 70 points from the amazon.co.uk star line: stars divided by five, times 70, rounded. A 4.5 becomes 63. A 5.0 becomes 70. The figure is the listing score, not a measured grate temperature.
Review volume
30%Up to 30 points from the rating count: log10 of the count, times 10, capped at 30. A few perfect stars stay below a mid-four from several hundred ratings. The count does not fill a blank specification.
Choose by what the steel covers, the regulator, whether the burner count agrees with the stated kilowatts, and whether you need a tabletop or a trolley. A high star line on a handful of ratings does not outrank a larger sample. Prices are the amazon.co.uk lines saved with this comparison. There is no laboratory test.
A stainless steel gas BBQ is an outdoor LPG grill sold with stainless burners, a stainless hood, or stainless cart panels. The label is not a guarantee that every panel is the same grade. Painted or powdered steel can sit next to stainless burners. Cast-iron grates and a ceramic sear zone are normal on a large trolley, and they are not the cabinet. Stainless resists rust better than bare mild steel. It still marks in coastal salt, pool chlorine, and under a cover put on while the steel is wet.
Stainless on the title can mean the burners, the hood, or the frame. Powdered steel, cast iron, and a plain metal line are different parts. Stainless still marks in salt and under a wet cover.
Patio propane is often about 37 mbar. Butane is often about 28 to 30 mbar. A cartridge cylinder needs its own screw-on. A 1 lb bottle line is not a standard UK patio cylinder.
GOV.UK says never use a barbecue indoors, in a tent, under an awning, or in a caravan. Turn the cylinder off first after cooking. If a soapy-water test still bubbles, stop and get advice.
Check what the listing actually calls stainless: burners, hood, frame, or cabinet. A second line that says powdered steel, alloy, cast iron, or plain metal is a clash, not a marine-grade shell. Then match the regulator. Patio propane is often about 37 mbar. Butane is often about 28 to 30 mbar. A cartridge cylinder needs its own screw-on, and a 1 lb bottle line does not suit a standard UK patio cylinder. If the hose is both included and missing, check the carton.
Read burner count and kilowatts as printed. A portable two-burner here states 4.7 kW. A portable three states 7 kW. A four-main trolley often states about 21 kW. A wide trolley often states about 27 to 28 kW. If the bullet and the power specification disagree, keep both and do not convert one into a measured result. A tabletop suits a trip. A wheeled trolley suits a garden party. A side sear, a rear burner, a window, and a cover change the job, not the rule that the grill stays outdoors.
Three typical situations, each with a recommendation from this comparison.
You want a wheeled trolley with a cover for a weekend party, and you will check the steel and the gas fittings when it arrives. The CosmoGrill Pro Deluxe 6+1 is about £299.99, at 4.5 from 366 ratings, score 89. Six main burners plus a side burner are named. The heat lines and the steel lines do not agree, and the regulator is listed both ways.
You want a two-burner you can lift, and you already own a regulator for your cylinder. The Onlyfire 2-burner is about £189.49, at 4.3 from 49 ratings, score 77, with a stated 4.7 kW and a cover. No regulator is named in the box. Skip it if you need a cabinet for a crowd.
You want a stainless trolley with a ceramic sear zone and a rear burner, and you will add a cover if the carton does not include one. The CosmoGrill Platinum 4+2 is about £502.55, at 4.6 from 36 ratings, score 80, with a 37 mbar propane hose named. Thirty-six ratings is a modest base at that shelf.
In this set the top pick is the CosmoGrill Pro Deluxe 6+1 at about £299.99. It scores 89, from 4.5 and 366 amazon.co.uk ratings, the largest sample here, with six main burners, a side burner, piezo ignition, a lid gauge, and a cover. The listing clashes on heat, a 12 kW bullet against 2,000 W, and on steel: stainless, an aluminium frame, and powdered steel. The regulator is both named and described as missing. The best value is the Onlyfire 2-burner at about £189.49, score 77, with 4.3 from 49 ratings and a stated 4.7 kW. No regulator is named in that box, and the same 49-rating line sits on the Onlyfire 3-burner at about £229.99. The covered Platinum at about £621.99 scores 81 from 4.6 and 45 ratings, and its burner count disagrees with the eight-burner bullet. The Platinum 4+2 at about £502.55 scores 80 from 4.6 and 36, with a sear zone and no cover named. The rotisserie bundle at about £676.16 shows 5.0 from 11 ratings, which does not outrank 366 reviews. The Yamara at about £539.99 rests on nine ratings. None of these scores is a laboratory cook or a BS EN 498 result.
Onlyfire 2-burner
Best value in this set: about £189.49, score 77, 4.3 from 49 ratings, stated 4.7 kW. No regulator is named in the box.
