Gas BBQ hose and regulator UK

Updated: 23 October 2026

The trolley is on the patio and the carton had a grate, a lid and no hose. A gas BBQ hose and regulator in the UK matches three things: the pressure on the appliance, the gas in the cylinder, and the valve on that cylinder. A product titled BBQ regulator is not that match by itself. On these 4 burner and 4+1 trolleys, the hose is missing from every contents line that is clear enough to read. Those rows are on the [4 burner gas BBQ comparison](/hub/grills-and-barbecues/4-burner-gas-bbq). The listing checks are on the [4 burner gas BBQ buying guide](/hub/grills-and-barbecues/4-burner-gas-bbq/sub/4-burner-gas-bbq-buying-guide).

Why these trolleys often need a separate regulator

On the three CosmoGrill rows, the included-components field lists a lid, a rack or a tray, not a hose or a regulator, and UK reviews say the regulator was not in the box. Both Campfire listings, at £169.99, say in the bullets that the regulator and hose are not included. The only review on the Campfire Pro+ says those parts were missing and that this was not obvious in the advert. The Oopsiou page does not state a hose, a regulator or a pressure. None of the six pages prints the data plate. A Cadac clip-on at £25 is one example of that extra.

37 mbar, 28–30 mbar, and patio gas

Liquid Gas UK puts butane at a nominal 28–30 mbar and propane at a nominal 37 mbar. Patio gas is propane for this purpose: Hamilton Gas Products describes it at 37 mbar, often with a 27 mm clip-on. A new regulator should be marked to BS EN 16129. The plate on the barbecue, not the amazon title, says which pressure the burners expect. Propane or patio gas means 37 mbar and that cylinder's connector. Butane means 28–30 mbar and the butane connector. Do not force the wrong fitting. If the plate is missing or disagrees with the cylinder, stop and ask a competent supplier before you buy a 37 mbar clip-on on a guess.

Hose condition and the leak check

Calor's barbecue guidance names hose to BS 3212 type 2 or BS EN 1763 Class B. Change a hose that is cracked, stiff or oil-soaked. Liquid Gas UK suggests a 10-year rule of thumb for a regulator when the maker is silent. Read the date stamp, and still replace a newer hose that is already cracked. Change cylinders outdoors. Before any burner is opened, brush soapy water on the regulator joint and both hose ends. Bubbles mean you shut the cylinder. If you doubt the result, do not use the barbecue. The first cook, lid open and one burner at a time, is on how to use a 4 burner gas BBQ. A side ring is another joint on this same hose.

When you stop instead of adapting a fitting

Stop when the connector does not fit. This page will not walk through forcing a POL nut or a clip-on. Stop when the regulator in the shed is marked for a different gas from the plate. UK and Ireland fittings differ, and Northern Ireland follows its own gas-safety rules. A Republic of Ireland valve is not a UK 27 mm assumption. Stop if anyone offers Autogas as a refill. Calor forbids that. Stop if the plan is to tee the barbecue into the house pipework. A portable cylinder barbecue sits outside the gas-work definition in regulation 2 of the 1998 regulations, which HSE's L56 spells out. Fixed pipework and a damaged valve are a Gas Safe engineer's job. Until the plate, the cylinder and the regulator agree, the burners stay unlit.

Common questions

Why is there no regulator in the box?
These listings leave it off the included-components line, and the Campfire bullets say so outright. UK reviews on the three CosmoGrill rows agree it was absent. Budget the fitting, and read the bullet before you pay. Some other amazon.co.uk listings do include a hose, which is why that line is worth checking every time.
Do I need 37 mbar or 28–30 mbar?
You need the pressure on the data plate, matched to the cylinder. Liquid Gas UK puts propane at a nominal 37 mbar and butane at 28–30 mbar. Patio gas follows the propane figure. None of these six amazon pages prints the plate, so you read it on the appliance when it arrives. A 37 mbar clip-on ordered before that is a guess.
Is patio gas the same as propane?
For regulator choice, yes. Hamilton describes patio gas at 37 mbar, commonly with a 27 mm clip-on valve. It is still propane, not a third pressure you can pair with a butane regulator. The cylinder label and the regulator mark should both say that 37 mbar class before you open the valve.
Can I use a butane regulator on a propane cylinder?
No. The nominal pressures differ, 28–30 mbar against 37 mbar, and the connectors are not meant to be forced. If the regulator you own does not match the plate and the cylinder valve, buy the one that does, or change the cylinder to the gas the plate names. Liquid Gas UK tells you not to force a fitting.
What hose standard should I look for?
Calor's barbecue guidance names hose to BS 3212 type 2 or BS EN 1763 Class B. Look for that mark, and reject tubing that only looks similar. Keep fat off it, keep it clear of the castors, and replace it when it cracks. A new regulator should carry BS EN 16129.
Is connecting the hose Gas Safe work?
Connecting a portable cylinder barbecue is outside the gas-work definition in regulation 2 of the 1998 regulations, which HSE's L56 explains. You still leak-check with soapy water and you still stop if a joint bubbles or the valve is damaged. A feed off the household pipe, or a damaged cylinder valve, is the Gas Safe job.
