Gas Bottles & Regulators

All our Gas Barbecues are compatible with LPG (Liquefied Petroleum Gas), either Propane (such as Patio Gas) or Butane

 

Whether you're new to gas BBQs or just need a refresher, this guide explains everything you need to know about the gas types and regulators compatible with your CosmoGrill barbecue.

 

PLEASE NOTE: NONE of our barbecues come with gas bottles/canisters, and some of our models DO NOT come with a regulator and gas hose. Please check the individual product listing before ordering

 

✅ Gas Types Supported

 

  • Propane (G31) – Requires a 37 mbar regulator
    🔴 Usually Red or Green gas bottle, ideal for year-round outdoor use, especially in colder weather

  • Butane (G30) – Requires a 28–30 mbar regulator
    🔵 Ussaly Blue gas bottle, best suited for use during warmer months

As long as the correct regulator is used, your BBQ can safely run on either Butane or Propane. This flexibility allows you to choose a gas type based on availability, season, or personal preference, making our BBQs suitable for most UK household setups.

 

🔌 Regulator & Hose Information

 

  • If your CosmoGrill BBQ includes a regulator:
    You'll receive a 27mm Clip-on 37 mbar regulator along with a gas hose as standard.

  • If your BBQ does not include a regulator:
    You’ll need to purchase a compatible regulator and gas hose separately, depending on your choice of gas. These are widely available online and often sold as a pack.

 

What Gas Bottle do I need for my BBQ?

 

Propane 37mbar 'Clip-on' regulator

If our barbecue comes with a regulator included, we recommend the purchase of the following propane bottles, depending on the number of burners.

[Rule of thumb: 3 or less burners = 5KG+ and 4 or more burners = 10KG+]

If you happen to have or plan on buying a 'screw-on' propane regulator, please know the following combinations will work.

If you happen to have or plan on buying a 'clip-on' 21mm butane regulator, we recommend the following gas bottle combinations below.

🏷️ Understanding the Labels on Your BBQ Packaging

 

You may notice one of the following gas category labels on your BBQ box:

  • I3+(28-30/37) – Compatible with both Butane (28–30 mbar) and Propane (37 mbar)

  • I3B/P(30) – Compatible with Butane/Propane mixtures at a fixed pressure of 30 mbar (often used across Europe)

These indicate the approved gas pressure levels and types for safe use.
