The best Gas regulators, compared.
Top pick: JD Brands POL screw regulator Best value: JD Brands POL handwheel – Best value as the lowest price in the set: score 69 at about £8.99, 37 mbar and a POL handwheel printed, 4.6 from 143 reviews. No kg/h and no hose-tail size. Updated 22.10.2026.
A gas regulator for a UK barbecue is a preset valve. It drops LPG cylinder pressure to the low pressure printed on the appliance plate. You buy one for a patio barbecue or an outdoor heater. Check the cylinder valve first, then the gas and the millibar figure. Green patio-gas bottles are propane, with a 27 mm clip-on and a regulator set to 37 mbar. Screw-on propane bottles take a POL regulator at the same 37 mbar. That fitting does not fit a 27 mm valve. Butane needs a clip-on at nominally 28–30 mbar, often 21 mm. A 20 mm clip-on is not a 21 mm one. A caravan regulator to EN 1949 is a different part. Prefer BS EN 16129 and a date under three years. If no life is stated, UK LPG guidance is 10 years. The hose is separate, usually an 8 mm nozzle, and rubber hose is replaced after five years or sooner if it is cracked. Fit and cook outdoors, and do not adjust the regulator. The checks are in the [gas regulator buying guide](/hub/grills-and-barbecues/gas-regulator/sub/gas-regulator-buying-guide).

Question 1 of 2
Which valve is on the cylinder?
The JD Brands PGR01 listing is about £9.99 and prints 37 mbar, 1.5 kg/h, and a POL screw that does not fit 27 mm patio bottles. amazon.co.uk shows 4.8 from 62 reviews. The listing claims UK safety standards without a standard number. One review notes a 2025 date stamp. Clips are not included. The checklist score is 84. It takes no badge. The handwheel is the lower price, and the Calor listing is the top pick on a different valve.
Pros
Cons
Best for: You have a Calor or Flogas POL screw propane cylinder and a 37 mbar appliance, and you do not have a 27 mm patio valve.
Less suitable: You use a green patio clip-on bottle. This listing says it will not fit.
Specifications
Common questions
Will it fit a 27 mm patio cylinder?
The listing says no. It is POL screw-on only and states that it does not fit 27 mm clip-on patio gas bottles.
What output is printed?
37 mbar for 37 mbar propane systems, at 1.5 kg/h. The hose-tail size is not printed.
Does it need a spanner?
The listing calls it a screw-on POL regulator and does not mention a handwheel. A spanner is not ruled out.
The Calor listing is the 27 mm propane patio regulator in this set, at about £13.77, with 37 mbar and an 8 mm nozzle printed. Part 601228 and maker Cavagna match the class sold for 5 kg and 13 kg patio cylinders. amazon.co.uk shows 4.7 from 1,114 reviews, the largest review count here. Capacity in kg/h is not on this listing, and a hose is not included. The checklist score is 89, so it is the top pick. It is not a measured outlet pressure.
Pros
Cons
Best for: You have a green 27 mm patio-gas cylinder and want the regulator that prints 37 mbar propane and an 8 mm nozzle.
Less suitable: You have a POL screw cylinder or a butane clip-on. This listing does not claim those valves.
Specifications
Common questions
Which bottles does the listing name?
Calor 13 kg and 5 kg green patio cylinders, Flogas 11 kg patio gas and 9 kg leisure gas, and a BP green 27 mm clip-on cylinder. The gas type printed is propane.
What pressure and outlet are printed?
37 mbar, with an 8 mm nozzle. The part number is 601228 and the manufacturer field says Cavagna.
Does the listing include a hose?
No. The text describes the clip-on regulator and an on/off lever. A hose is not in the included items.
Adventure Outdoor Supplies AOS0036 is about £13.95 and prints the patio set in one place: 27 mm, 37 mbar, 1.5 kg/h and an 8 mm tail, for 5 kg and 13 kg bottles. amazon.co.uk shows 4.7 from 34 reviews. One review describes a switch that would not click and a refund. No hose is included. The checklist score is 80. It prints the flow the Calor listing omits, on a much smaller review count.
Pros
Cons
Best for: You want a 27 mm patio regulator with pressure, flow and hose-tail size all printed, and you already have a hose.
Less suitable: You need a POL screw fitting or a butane regulator. This listing is 27 mm propane.
Specifications
Common questions
Does the listing name 5 kg and 13 kg patio bottles?
Yes. It says patio gas cylinders including 5 kg and 13 kg, and Calor Patio Gas or an equivalent 27 mm clip-on.
What flow and outlet are printed?
1.5 kg/h at 37 mbar, with an 8 mm hose tail. A hose is not listed as included.
Is a camping stove mentioned?
Yes. The bullets include camping stoves, patio heaters, grills and burners, still at the printed 37 mbar propane setting.
The JD Brands HWR01 is the lowest price in this set at about £8.99, with 37 mbar and a POL handwheel printed, and 4.6 from 143 reviews. Capacity and hose-tail size are absent. Reviews include spare washers, a date stamp a year old, one unit that stopped passing gas, and one bottle with no room to turn the wheel. The checklist score is 69. It is the best value because it is the lowest shelf price with 37 mbar and a no-spanner POL fit printed. It is not a lab test.
Pros
Cons
Best for: You have a POL propane cylinder, want 37 mbar without a spanner, and you can check the manufacture date and the collar clearance.
Less suitable: You need a printed flow rate, an 8 mm tail in the listing, or a 27 mm patio clip-on.
Specifications
Common questions
Do you need a spanner?
The listing says no. It is a handwheel POL fitting. Reviews also mention spare rubber washers, which the bullets do not list.
Is the capacity printed?
No. Outlet pressure is printed as 37 mbar. Kilograms per hour and the hose-tail size are not on the listing.
Which bottles does it name?
Most UK propane bottles, including Calor and Flogas, with a POL screw. It does not say it fits a 27 mm clip-on.
The Cofan listing is about £11.69 for a steel butane regulator, model 41007762, grey, 180 g, diameter 9 cm. amazon.co.uk shows 4.6 from 92 reviews, and the review texts are mostly one line. Valve size, millibar and hose tail are not printed. Amazon notes that some products cannot be delivered outside mainland UK. The checklist score is 24. The listing does not say it fits propane.
Pros
Cons
Best for: You already know this model matches your butane valve and you only need the price and the material from the listing.
Less suitable: You need the listing itself to name 21 mm, 28 mbar, or a propane fit.
Specifications
Common questions
What valve does it fit?
The listing does not say. One review reports a fit on a Repsol clip-on butane cylinder in a camper. That is a single report, not a specification.
Can it be used with propane?
The listing does not say so. The title is a butane regulator. Pressure is not printed.
What is it made of?
Steel, grey, 180 g, with a printed diameter of 9 cm. Model number 41007762.
The HowseHold kit is about £16.99 and is the only listing here whose title includes a 2 m hose and clips. The included-components line agrees. One bullet says the opposite. Millibar is not printed. Capacity is 1.5 kg/h and the inlet is 16 bar. amazon.co.uk shows 4.6 from 40 reviews, and reviews talk about the hose, the clips and a 27 mm fit. The checklist score is 47, with 8 points off for the hose clash.
Pros
Cons
Best for: You need a 27 mm regulator and a 2 m hose together, and you can live with a listing that contradicts itself on the hose.
Less suitable: You need a printed 37 mbar figure, or you already have a sound hose and only want the regulator.
Specifications
Common questions
Does the box include a hose?
The title, the special-features line and the included-components line say a 2 m hose and clips. A later bullet says the regulator only and no hose. Reviews describe a hose and jubilee clips.
Is 37 mbar printed?
No. The listing says low pressure, 1.5 kg/h and a 16 bar maximum inlet.
Which fitting is it?
27 mm clip-on for patio propane cylinders, tool-free, as printed. It says to check the measurements in the images.
The JD Brands BGR01 listing is about £13.01 and is titled as a blue 21 mm butane clip-on for barbecues, camping and patio heaters. Millibar, flow and hose-tail size are absent. amazon.co.uk shows 4.4 from 90 reviews. Several reviewers say a 20 mm regulator arrived and was returned. Positive reviews describe an easy fit when the valve matched. The checklist score is 33. That 20 mm note is not a claim that every unit is 20 mm.
Pros
Cons
Best for: You have measured a 21 mm butane valve and will check the marking on the unit before you fit it.
Less suitable: You need a printed 28 mbar figure, or you cannot return a 20 mm unit if that is what arrives.
Specifications
Common questions
Is it 21 mm?
The title says 21 mm Calor-style butane valves. Several reviews say the box was marked 20 mm and did not fit. That conflict is unresolved in the listing.
What pressure is printed?
None. The listing does not give a millibar figure or a kg/h capacity.
Does it fit every gas bottle?
No. The title limits it to 21 mm butane valves and does not claim propane or a 27 mm patio cylinder.
HowseHold’s regulator-only listing is about £12.99 for a 27 mm clip-on with 1.5 kg/h and a 16 bar inlet printed, made in China, hose excluded. Outlet pressure in millibar is not printed. amazon.co.uk shows 4.2 from 5 reviews, and the two UK reviews are only a sentence each. The checklist score is 51. Do not read “low pressure” as 37 mbar.
Pros
Cons
Best for: You already know you need a 27 mm regulator and a separate hose, and you accept a listing with no millibar number.
Less suitable: You want 37 mbar printed on the page before you buy, or you need POL or butane.
Specifications
Common questions
Is the outlet pressure printed?
No. The listing says low pressure, 1.5 kg/h and a 16 bar maximum inlet. It does not print a millibar figure.
Does it include a hose?
No. The listing says the regulator only, for people who already have a hose.
Will it fit every barbecue?
The listing does not say that. It says 27 mm patio cylinders and tells you to check the measurements in the images.
Eight amazon.co.uk gas regulator listings were scored with a checklist, not a lab test and not a measured outlet pressure. Printed millibar is 25 points. A clear cylinder fitting is 20, or 10 if reviews dispute the size. Capacity or a hose-tail size is 15. Stars are the amazon.co.uk figure times 3. Review volume is 15, 10, 6 or 3 once the count passes 200, 50, 20 or 5. A listing that contradicts itself on the hose loses 8. Those checklist points sum to 90 before the penalty. The weights below are the same shares, rounded so they sum to 100. The hose deduction stays a penalty inside the sort, not a weight. The Calor 27 mm listing scores 89 and is the top pick. The JD Brands POL handwheel scores 69 and is the best value: the lowest shelf price in the set, at about £8.99, with 37 mbar and a no-spanner POL fit printed.
Printed outlet pressure
28%Up to 28 points, the rounded share of the 25-point checklist line. The listing has to print the millibar figure. A line that only says low pressure does not score it. 37 mbar is the propane figure in this class. Butane is nominally 28–30 mbar.
Cylinder fitting
22%Up to 22 points, the rounded share of the 20-point checklist line. A clear 27 mm, POL or butane clip-on scores the full share. Reviews that dispute the size, as on the titled 21 mm butane listing, cut that line.
Capacity or hose tail
17%Up to 17 points, the rounded share of the 15-point checklist line. A printed kg/h figure or a printed hose-tail size, usually 8 mm in this class, scores it. A blank capacity and a blank tail do not.
Stars
17%Up to 17 points, the rounded share of stars times 3. A 4.7 is 14 on the raw checklist. The star line is the amazon.co.uk figure, not a lab score.
Review volume
16%Up to 16 points, the rounded share of the 15, 10, 6 or 3 point bands at 200, 50, 20 or 5 reviews. The Calor listing has 1,114 reviews. The HowseHold regulator-only listing has 5.
Match the cylinder valve and the millibar figure on the appliance plate before you compare stars. A gas regulator here is a preset valve for a patio barbecue, a pizza oven or an outdoor heater. On this page the shelf prices run from about £8.99 to about £16.99. A listing that does not print millibar is not a 37 mbar regulator, and a POL screw does not fit a 27 mm patio clip-on.
A barbecue gas regulator is a preset valve. It drops LPG cylinder pressure to the low pressure on the appliance plate. Shoppers here are replacing a regulator on a patio barbecue, a pizza oven or an outdoor heater. The first split is the cylinder valve. The brand comes after that. Read the plate for gas and millibar. Propane plates in this class are 37 mbar. Butane plates are nominally 28–30 mbar.
A green patio cylinder is 27 mm propane at 37 mbar. A POL regulator is a left-hand thread and does not fit that valve. The JD Brands POL screw listing states the exclusion. Colour is not the specification.
A high star line does not print the millibar figure for you. Check the manufacture date. If no life is stated, UK LPG guidance is 10 years. BS 3016 is already past that. Change a worn unit sooner.
Rubber hose to BS 3212, BS EN 1763-1 or BS EN 16436-1 is replaced after five years, or earlier if it is cracked, soft or stiff. A 20 mm clip-on is not a 21 mm one. A cartridge system is its own regulator. Several reviews of one butane listing say 20 mm arrived. That is not every unit.
Read the appliance plate before the star rating. Propane plates in this class are 37 mbar. Butane plates are nominally 28–30 mbar. GOV.UK lists Group P at a nominal 37 mbar and Group B at a nominal 29 mbar. The two regulators are not interchangeable. An EN 1949 caravan is often 30 mbar for both gases, and that is a different part. Then match the valve. A 27 mm clip-on is patio propane. A POL screw is standard propane, a left-hand thread, and it does not fit 27 mm.
Prefer a regulator marked to BS EN 16129, with a manufacture date under three years. If no life is stated, UK LPG guidance is 10 years. BS 3016 is already past that. A five-year guarantee is not the same as changing the unit by 10 years. Change it sooner if it is worn. Stars do not prove the valve, and a safety line with no standard number is not BS EN 16129. Treat the hose as separate. This class usually has an 8 mm nozzle. Calor prints an 8 mm nozzle and includes no hose.
Three typical situations, each with a recommendation from this comparison.
You have a 27 mm clip-on patio cylinder and a 37 mbar propane plate. Ignore POL bargains. The Calor listing prints 37 mbar, 27 mm and an 8 mm nozzle at about £13.77, with 4.7 from 1,114 reviews. It does not print kg/h and it does not include a hose. It is the top pick on the checklist.
You have a screw propane cylinder, including some pizza ovens and larger bottles, and you do not have a 27 mm patio valve. The JD Brands POL screw listing prints 37 mbar and 1.5 kg/h at about £9.99 and states that it does not fit 27 mm. It is 4.8 from 62 reviews. The handwheel is the lower price if you do not need kg/h printed.
You need a butane clip-on, not a 37 mbar propane regulator, and you will not use it in cold weather. The JD Brands listing is titled 21 mm at about £13.01 and does not print millibar. It is 4.4 from 90 reviews. Several reviews say 20 mm arrived, so check the marking before you fit it. That is not a claim about every unit.
The top pick is the Calor 27 mm patio regulator at about £13.77. The checklist score is 89. It prints 37 mbar propane, a 27 mm clip-on and an 8 mm nozzle, with 4.7 from 1,114 reviews. It does not print kg/h and it does not include a hose. The best value is the JD Brands POL handwheel at about £8.99, the lowest price in this set, score 69, with 37 mbar and a no-spanner POL fit printed and 4.6 from 143 reviews. It does not print kg/h or a hose-tail size. These scores are a listing checklist, not a measured outlet pressure. A POL part does not fit a 27 mm patio valve.
JD Brands POL handwheel
Best value as the lowest price in the set: score 69 at about £8.99, 37 mbar and a POL handwheel printed, 4.6 from 143 reviews. No kg/h and no hose-tail size.
