The best 3 burner gas BBQs, compared.
Top pick: CosmoGrill Wabaya with cover Best value: CosmoGrill Wabaya, black – Lowest price among listings that print a 37 mbar propane hose, about £199.99 for the same stated Wabaya layout. No star line on the page. Updated 22.10.2026.
A 3 burner gas BBQ is an outdoor LPG grill with three independently controlled heat sources under one hood, usually plus a warming rack. UK shoppers choose one when a two-burner means batch cooking and a four-burner cart is more patio than they need. On a UK listing the words “3 burner” can mean three main burners, or two main burners plus a ceramic sear burner, so the bullet matters more than the title. A suitable grill has a grate you can measure, a 37 mbar propane fitting that matches the data plate, ignition that sparks, and a grease path off the flame. Butane sits at about 28–30 mbar and needs its own regulator. A 1 lb bottle or a 5/8 inch hose tail is not a UK patio-gas clip-on. Painted steel rusts outdoors, which is why stainless costs more for the same burner count. Keep cylinders outside, turn the gas off before the controls, and keep the cook out of tents, awnings, caravans and balconies. The checks are in the [3 burner gas BBQ buying guide](/hub/grills-and-barbecues/3-burner-gas-bbq/sub/3-burner-gas-bbq-buying-guide).

Personal buying guide
Question 1 of 2
Where will you cook?
The Wabaya with cover is about £219.99, model 935, with a star line of 5.0 from one rating. Bullets state 7.5 kW as two 2.5 kW burners plus a 2.5 kW ceramic sear, a 47 × 37 cm grate, piezo ignition, two ABS wheels, and a 37 mbar propane hose. Butane is a separate buy. The title includes a cover. The included line does not. That single review likes the sear zone and a domed hood, fitted a 5 kg Calor bottle tightly, and wants the cover to fit with the side tables down.
Pros
Cons
Best for: A garden wagon where you want the 37 mbar propane hose and a cover named in the title.
Less suitable: Butane, which the bullet says needs another regulator, or a decision based on more than one review.
Specifications
Common questions
Is the propane hose a UK 37 mbar fitting?
The bullet says a propane regulator and hose are included at 37 mbar. It also says butane needs a separate regulator and hose. The included-components line names an adapter hose and a thermometer.
Can the gas bottle stay in the cabinet while you cook?
The bullet says storage suits 5–11 kg tanks and tells you not to light the barbecue with a tank in storage. Remove it before lighting. The only review says a 5 kg Calor bottle fitted, tightly.
What are the three burners?
The burner-count fields say 2 main and 1 side. The bullets say two 2.5 kW stainless burners and a third 2.5 kW ceramic sear burner, 7.5 kW together. They do not describe a side hob.
Onlyfire lists this tabletop 3-burner at about £229.99 on amazon.co.uk, with 4.3 from 49 ratings, the largest star sample in this set. The heating field says 7 kW and a bullet says 24,000 BTU across three stainless burners, with electric ignition, a 22 × 13 in grate, and folding legs. A regulator is not in the included list. Reviews praise the steel and first-time lighting. They also report sharp edges, a broken middle-burner spark wire, fittings that needed an adapter, and a grate that bent after two uses.
Pros
Cons
Best for: A table or a van where you already own a propane hose that fits this grill.
Less suitable: Anyone who needs a 37 mbar hose in the carton and a weather cover.
Specifications
Common questions
Does this listing include a regulator and hose?
The included-components line lists a lid, folding legs, and a carry handle. It does not name a regulator or a hose, and there is no mbar figure. Reviews mention bottled gas, a camper-van supply, and fittings that needed an adapter.
How big is the cooking grate?
The bullet says a 22 × 13 in stainless grate, which the page also calls 286 square inches. The cooking-surface field says 1,847.69 square centimetres. One review instead measured about 48 × 34 cm. The table shows 55.9 × 33 cm so every grate uses centimetres.
Is it a trolley barbecue or a tabletop?
The installation type is tabletop. The bullets give folding legs, a locking lid, and a carry handle, and the item size is about 60 × 35.5 × 36.5 cm at 15 kg. Wheels are not listed.
This Onlyfire cart is about £279.99, with 4.3 from 18 ratings. The listing states three burners at 7 kW, a 22 × 13 in stainless grate, twist-start ignition, a lid gauge, and a folding trolley. The included-components line lists only a lid, while a bullet describes a regulator for a 1-pound bottle and writes the pressure as 30 MPA. A large tank needs an extra hose tail. Reviews praise rust resistance and heat control. One buyer wanted the hot plate from a video, and one says the flame would not sear a steak.
Pros
Cons
Best for: A patio cart if you already use a 1 lb cylinder or you can buy the large-tank hose the bullet names.
Less suitable: A UK patio bottle at a stated 37 mbar, which this page does not print.
Specifications
Common questions
Which gas bottle does the listing say it connects to?
The bullet says it connects directly to a 1-pound bottle and that the regulator is for that bottle. A large propane tank needs a 5/8-inch hose-tail connector and hoses, which the same bullet says you buy separately. The pressure string on the page is 30 MPA, not a mbar figure.
Is the cooking area the same as the tabletop Onlyfire?
The bullet and the cooking-surface field both say 22 × 13 in, also written as 286 square inches. That is the same grate size the tabletop listing prints. This cart is 87.5 × 35.5 × 97 cm and 20.5 kg. The comparison table shows 55.9 × 33 cm.
Does the box include a weather cover?
Included components list a lid. The item highlight names the lid and a thermometer. A separate weather cover is not listed.
Modern Outdoor Living lists this wheeled 3-burner at about £169.99, with 3.8 from 8 ratings and only three review texts on the listing. Bullets say three 3 kW burners, automatic ignition, two wheels, side tables, cupboard doors, and a propane hose. There is no mbar, no weight, and no dimension line. The bestseller rank sits in Charcoal Barbecues. One review reports a broken gauge and unclear battery fitting. The saved product image is a small thumbnail.
Pros
Cons
Best for: A low shelf price when you can check the hose fitting yourself, because mbar is not printed.
Less suitable: Anyone who needs a measured grate or a 37 mbar line before ordering.
Specifications
Common questions
Is a propane hose in the box?
The bullet says a propane regulator and hose are included. It does not give a mbar figure. Included components list a rack and a thermometer, not the hose.
How wide is the grate?
The page does not print a centimetre grate or an item size. The cooking-area bullet says space for 5–10 people. Weight is also missing.
What do the saved reviews say about the gauge?
The listing line is 3.8 from 8 ratings. Three review texts are saved. One says the temperature gauge arrived broken and that the ignition battery location is unclear. Another calls it a great little barbecue. A third had not used it yet.
Zorba Trading Ltd sells this Modern Outdoor Living 3-burner at about £169.99, with 2.9 from 4 ratings. The bullet is the one in this pair that prints a grate, 410 × 415 mm, plus 9 kW, side tables, a cupboard, a built-in thermometer, and a propane hose. Depth is 45 cm on one line and 43 cm on another. Ignition and mbar are absent. Reviews on the listing describe transit damage, a missing manual, and parts that do not fit, with one calling assembly easy. UPC 633710673945 is not the UPC on the other £169.99 listing.
Pros
Cons
Best for: Comparing a printed 410 × 415 mm grate at about £169.99 against the other Modern Outdoor Living row, which has no grate size.
Less suitable: A first barbecue if you need clear assembly instructions. The file's reviews say those were missing or unclear.
Specifications
Common questions
What cooking area does the bullet give?
410 mm × 415 mm. There is no square-centimetre field. The cart is listed at 18 kg, 115 cm wide and 103 cm high, with depth printed as both 45 cm and 43 cm. The comparison table shows 41 × 41.5 cm.
Is the propane regulator included?
The bullet says a propane regulator and hose are included. It does not state mbar. Included components name the thermometer. Ignition type is not on the page.
What do the four ratings rest on?
The listing line is 2.9 from 4 ratings. Three review texts are saved: dented and scratched on arrival with unclear instructions, easy to assemble and good value, and no manual with parts that do not fit.
This black Wabaya is the same model 935 at about £199.99, £20 under the cover listing. The listing states the 7.5 kW sear layout, the 47 × 37 cm grate, two ABS wheels, piezo ignition, and a 37 mbar propane hose, with butane excluded. The title and included line do not mention a cover. There is no star line and no review text on the listing, so the lower price is a catalogue difference, not a reviewed one. The in-use rule is the same: remove the cylinder from storage before lighting.
Pros
Cons
Best for: The same Wabaya spec as the cover listing if you already own a cover and want the £199.99 row.
Less suitable: Choosing on star ratings, which this page does not show.
Specifications
Common questions
How is this listing different from the Wabaya with cover?
This ASIN is £199.99 and the colour line says black. The other Wabaya ASIN is £219.99 and the title says black with cover. Both use model 935, 7.5 kW, a 47 × 37 cm grate, and a 37 mbar propane hose. This page has no customer-review line.
Does the box include a 37 mbar propane hose?
Yes. The bullet says a propane regulator and hose are included at 37 mbar. Butane needs a separate regulator and hose. Included components list an adapter hose and a thermometer.
Can you leave the cylinder in the cabinet while cooking?
The bullet says 5–11 kg tanks fit the storage space and tells you not to light the barbecue with a tank in storage. Take it out before lighting.
Six amazon.co.uk listings were scored from 0 to 100 by scaling the star line: stars divided by 5, times 100. A 4.3 becomes 86, a 5.0 becomes 100, a 3.8 becomes 76 and a 2.9 becomes 58. A page with no star line scores 0. That figure is the listing average, not a lab test, and it is separate from the badges. The top pick is the largest review sample, 4.3 from 49 ratings. The best value is the lowest price among rows that print a 37 mbar propane hose. Grate lines in inches or millimetres are shown in centimetres in the table so the row uses one unit.
Amazon star line
100%The whole score is the amazon.co.uk star average scaled to 100: stars divided by 5, times 100. A 4.3 becomes 86, a 5.0 from one rating becomes 100, a 3.8 becomes 76 and a 2.9 becomes 58. No star line stays at 0. Review count does not add points. The top pick and the best value are display awards on top of that score: the largest sample at 4.3 from 49, and the lowest price that prints 37 mbar propane. This is not a lab cook.
Choose the burner layout before the star line. Three main burners and two burners plus a ceramic sear are both sold as a 3 burner gas BBQ. Then match the grate to the number of people you actually cook for, using the centimetre or inch line rather than a headcount slogan. The hose has to match the cylinder: 37 mbar propane is the UK patio figure, and butane needs its own regulator. A listing with no star line can still be the best value when it is the lowest price that prints that 37 mbar hose.
A 3 burner gas BBQ is an outdoor grill that burns LPG. Three heat sources sit under one hood, each with its own control, and most carts add a warming rack. UK shoppers look at this size when two burners mean cooking in batches and a four-burner trolley is wider than the patio. The words on amazon.co.uk are loose. Some listings have three main burners. Others have two main burners and a ceramic sear burner. A field that says “1 side” can mean that sear zone, not a pan hob.
On the Wabaya pages the burner-count fields say 2 main and 1 side. The bullets say two 2.5 kW stainless burners and a 2.5 kW ceramic sear, and they do not describe a hob for a pan. A side rack on the Onlyfire cart is a shelf for plates. Read the bullet before you expect a saucepan ring.
The Onlyfire cart bullet is written for a 1 lb bottle and a 5/8 inch hose tail for a large tank, and it prints 30 MPA. That is not a UK 27 mm patio-gas clip-on, and it is not 37 mbar. The tabletop does not name a regulator at all. Match the fitting to the cylinder you own.
Light with the lid open and leave the cart still while it is lit. On the Wabaya, take the 5–11 kg cylinder out of the cabinet before lighting. Stop if a soapy-water test still bubbles, the hose or a burner is cracked, or flame reaches the hose. Do not tape a hose.
The third burner is the first check, because the title “3 burner” is not one layout. CosmoGrill Wabaya states two 2.5 kW stainless burners plus a 2.5 kW ceramic sear, 7.5 kW together. The burner-count fields on the same pages say 2 main and 1 side. The bullets do not describe a pan hob, so “side” here is the sear zone inside the grill. Onlyfire states three stainless burners and 7 kW, with a 24,000 BTU bullet on the tabletop.
The grate comes before a guest count, and the hose comes before the brand. Dunelm maps a 3-burner to about 6–10 people and a 4-burner to about 10–14. Sahara maps a 3-burner to about seven to nine. Gardenbox prefers area, about 2,500–3,500 cm² for four to six. The Wabaya grate is 47 × 37 cm, stated as 1,739 cm². Onlyfire prints 22 × 13 in on both the tabletop and the cart. One Modern Outdoor Living bullet prints 410 × 415 mm. The other prints no centimetre grate, only a 5–10 people line.
Three typical situations, each with a recommendation from this comparison.
You cook for about four to six and you want a hot zone beside a gentler one. The black Wabaya states two 2.5 kW burners plus a 2.5 kW ceramic sear, a 47 × 37 cm grate and a 37 mbar propane hose, at about £199.99. The page has no star line. Take the cylinder out of the cabinet before you light it.
You want a lidded grill you can carry to a table or a camper, and you already own a propane hose that fits. The Onlyfire tabletop is about £229.99, at 4.3 from 49 ratings, with folding legs and a 22 × 13 in grate stated as 7 kW. A regulator is not in the included list.
You already use a patio-gas cylinder and you want 37 mbar propane named in the box. The Wabaya with cover is about £219.99, model 935, and the one review fitted a 5 kg Calor bottle tightly. Butane needs another regulator. The cover is in the title, not on the included-components line.
The top pick is the Onlyfire tabletop 3-burner at about £229.99. It has the largest amazon.co.uk sample in this set, 4.3 from 49 ratings, which scales to 86, with three stainless burners stated at 7 kW and folding legs. A regulator is not in the box list, and reviews include a dead middle burner and fittings that needed an adapter. The best value is the black CosmoGrill Wabaya at about £199.99, the lowest price that prints a 37 mbar propane hose, with a 7.5 kW sear layout and a 47 × 37 cm grate. That page has no star line. The cover variant at about £219.99 is the same model 935 with 5.0 from one rating. None of these scores is a lab cook.
