Gas Bottles & Regulators

All our gas barbecues are compatible with either Propane (Patio) or Butane LPG (Liquefied petroleum gas)

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.

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

 

Your CosmoGrill BBQ is compatible with both Propane and Butane, depending on the regulator used:

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

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

🧠 What This Means

 

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.

🏷️ 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 at a fixed pressure of 30 mbar (often used across Europe)

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

🔌 Regulator & Hose Information

 

  • If your BBQ includes a regulator:
    You'll receive a 27–28mm clip-on 37 mbar regulator (suitable for Propane) along with a 2m gas hose as standard.

  • If your BBQ does not include a regulator:
    You’ll need to purchase a compatible regulator and 2m hose separately, depending on your choice of gas. These are widely available online and often sold as a pack.

What gas do you need for your barbecue?

 

Propane 37mbar 'Clip-on' regulator

If the barbecue comes with a regulator included, you will need to purchase one 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.

Propane 37mbar 'Screw-on' regulator

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

Butane 28mbar 'Clip-on' regulator

  • Calor Butane Gas 7kg, 15kg (BLUE BOTTLES)
  • Flogas Butane Gas 7kg, 13kg (YELLOW BOTTLE)

We highly recommend against buying any butane 28mbar 'Screw-on' regulator as they tend to only work with 4.5kg butane bottles, which will not provide enough gas pressure for any of our models, not even our Compact 2 burner.
