If you’ve ever stood in front of a rack of gas bottles and thought, “Which one do I need – butane or propane?” you’re not alone. It’s one of the most common questions we get from customers across the UK.
Both gases are forms of LPG (liquefied petroleum gas), and they’re both great sources of energy. But they behave differently, especially in the cold – and that’s where it really counts here in Britain.
What’s the Difference Between Propane and Butane?
Here’s the short answer: propane works better in cold weather and outdoors, while butane is more efficient for indoor and warmer weather use.
To help you decide which is right for you, we’ve put together a clear comparison of their benefits.

Benefits of Propane vs Butane
| Feature / Benefit | Propane | Butane |
| Cold weather performance | Works in temperatures as low as -42°C – ideal for UK winters | Stops working below 0°C – not suitable for cold conditions |
| Best suited for | Outdoor use, all-year-round setups | Indoor use or warm weather conditions |
| Common applications | BBQs, patio heaters, static caravans, off-grid heating | Camping stoves, portable indoor heaters, small appliances |
| Efficiency | Slightly lower energy content per litre | Higher energy content per litre – more efficient burn |
| Bottle storage | Can be stored outdoors safely | Should be stored indoors |
| Burning pressure | Higher pressure – good for commercial and industrial equipment | Lower pressure – better for small, domestic appliances |
| Ease of use | Requires screw-on regulator | Often uses clip-on regulators – quicker to connect |
| Price | Slightly more expensive per bottle | Generally cheaper |
| Availability | Widely available in red or green cylinders across the UK | Commonly sold in blue bottles |
Choosing the Right Gas for You
In simple terms:
- Choose propane if you need gas for outdoor use, cold weather, or heavier-duty appliances.
- Choose butane if you’re using it indoors, during spring and summer, or with smaller portable heaters.
Still not sure? It depends on how and where you’re using it. If you’re running a patio heater in January – propane. If you’re heating a conservatory in April – butane might be perfect.

What is the effect on your carbon emissions?
When it comes to carbon emissions, both butane and propane are fossil fuels, so they do produce CO₂ when burned. However, compared to coal or heating oil, LPG gases are considered cleaner-burning. That means they release less carbon dioxide per unit of energy produced, as well as fewer harmful pollutants like soot and sulphur.
Between the two:
- Butane burns slightly more efficiently, meaning you may use less gas to produce the same amount of heat.
- Propane, while slightly less efficient, still has a relatively low carbon output and is better suited for colder, outdoor environments – where energy loss can be higher.
In real-world terms, if you’re switching from oil heating or solid fuel to LPG, you’ll likely reduce your overall carbon footprint. However, for those looking to go further in cutting emissions, some suppliers now offer bio-LPG, a renewable version made from plant-based sources.
To sum up: Both gases produce carbon emissions, but they’re among the cleaner fossil fuel options available today – and switching to LPG from more polluting fuels is often a step in the right direction for both efficiency and the environment.

FAQs
It depends on the appliance and the regulator it uses. Some appliances are made specifically for one type of gas, while others can be adapted. Always check the manufacturer’s instructions before switching gases – using the wrong one could cause performance issues or damage.
Propane turns to gas at much lower temperatures, making it reliable in cold conditions. Butane can struggle to vapourise when it’s chilly, which means your appliance may not work properly or might not ignite at all in winter.
Prices can vary depending on the supplier, location, and bottle size. Generally speaking, butane may be slightly cheaper per litre, but propane is often better value for money in colder months due to its reliable performance.
Propane is designed for outdoor use and storage, even in freezing conditions. Butane, on the other hand, should ideally be stored indoors or somewhere sheltered to avoid performance issues in the cold. Always keep bottles upright, well-ventilated, and away from heat sources.
Yes – propane and butane operate at different pressures and require specific regulators. Propane typically uses a red regulator (high pressure), while butane uses a blue one (lower pressure). Using the wrong regulator can be dangerous.
Propane is the preferred option for most UK barbecues, especially if you’re cooking outside year-round. It performs better in all weathers and many BBQs are designed with propane use in mind.
No – they must be kept separate. Mixing gases yourself is dangerous and not allowed. Some suppliers offer mixed LPG, but this is professionally blended and sealed. Always use bottles as supplied by a certified provider.
Both gases are naturally odourless, but an artificial scent is added for safety. The smell is similar in both – often described as sulphur-like – so you can detect leaks easily.
Compared to other fossil fuels, both gases burn cleanly and produce fewer emissions. They’re not renewable, but they are considered a cleaner energy option, especially where electricity isn’t available.
Look at the label on the bottle or the colour of the regulator. Propane bottles are often red or green, while butane bottles are typically blue. Your supplier can also confirm the type if you’re unsure.
