When the sun's out and the sausages are calling, firing up the bbq is a quintessential part of British summertime. But before you get sizzling, you'll need to decide which gas to use: propane or butane. Both are liquefied petroleum gases (LPG) and will get the job done, but they have their own quirks that might make one a better choice for your needs.
Propane gas for bbq (Red Cylinder)

Propane is a popular choice for BBQs in the UK, and for good reason. Here's the lowdown:
- All-Weather Champ: Propane's biggest advantage is its ability to handle the unpredictable British weather. It has a very low boiling point of -42°C. This means it will readily turn into a gas, even on a chilly spring evening or a surprisingly cold summer's day. You can happily leave your propane cylinder outside year-round without worrying about it struggling to work.
- Higher Oomph: Propane generally has a higher calorific value, meaning it releases more energy when it burns. This translates to a hotter grill and faster preheating times – ideal when you're keen to get those burgers cooking.
- Widely Available: You can find propane cylinders in various sizes from Energas of 3.9kg, 6kg, 11kg, 12.7kg, 19kg and 47.2kg at any of our 15 locations across the UK or your local stockist. We also stock propane gas regulators in store too if you swing by to collect your propane gas bottle
- Good for Larger BBQs: If you've got a big beast of a BBQ with multiple burners, propane is often the preferred choice as it can maintain a consistent and high heat output across a larger cooking area.
- Cylinder Colours and Fittings: Energas propane cylinders are red and you'll need a propane-specific regulator to connect it to your BBQ. We can help you in store with both your BBQ gas and correct gas regulator you'll need.
Butane gas for bbq (Blue Cylinder): A Solid Alternative

Butane is another option, often found in blue cylinders. Here's what you need to know:
- Warm Weather Warrior: Butane is more efficient in warmer temperatures. It has a higher boiling point of -2°C, so it works best when the mercury is above freezing. If you're mainly a fair-weather griller, butane can be a cost-effective option.
- Lower Price Point: Generally, butane can be slightly cheaper to buy than propane. If you don't BBQ frequently, the savings might add up.
- Cleaner Burn (Potentially): Some argue that butane burns a little cleaner than propane, potentially having a slightly smaller environmental impact in terms of emissions.
- Good for Portability: Energas Butane cylinders come in 4.5Kg, 7Kg and 13Kg lighter sizes, making them a good choice for portable BBQs, camping trips, and picnics.
- Cylinder Colours and Fittings: Energas butane gas cylinders are blue and require a different regulator (typically a clip-on type) than propane. Again, we stock these in store, so be sure to pop into your local Energas branch or stockist and you can pick up your gas and regulator at the same time.
Making the call: Which BBQ gas to pick?
For most BBQ enthusiasts in the UK, propane is generally the recommended choice. Its ability to perform reliably in colder weather means you won't be caught out if the temperature drops. The higher heat output is also a bonus for achieving those lovely seared marks on your steaks.
However, if you primarily BBQ in the warmer months and have a smaller, portable grill, butane can be a more economical option. Just be mindful that it might not perform well if it gets a bit nippy.
Top Tip: Always check your BBQ manufacturer's instructions to see if they recommend a specific type of gas. Using the wrong type could affect performance and potentially be unsafe.
