You'll need to pick us some gas.
We can supply to certain postcodes local to us but for further afield we recommend the supplier Calor gas.
Calor patio gas is supplied in a choice of two different sizes - 5kg (suitable for use inside the cart of old style Weber® Spirit, Genesis or Summit BBQs) and 13kg (suitable for storage next to or behind your Weber® BBQ).
Current edition Weber® BBQs are not designed to be compatible with the red propane or blue butane bottles. Swapping over the hose and regulator to use the incorrect gas type will void your BBQ's warranty (don't do it!).
