If you’ve ever looked into different energy sources for your home or business, you’ve likely come across natural gas and LPG. They’re both commonly used for heating, cooking, and hot water in the UK, but they’re not the same thing. Understanding the difference between natural gas and LPG can help you choose the right option for your needs, especially if you live in a rural area or are thinking about switching suppliers.
What is Natural Gas?
Natural gas is a fossil fuel that’s mostly made up of methane. In the UK, it’s delivered to homes and businesses through the mains gas network – a vast underground system of pipelines that connects most towns and cities. If you’ve got a gas boiler or cooker that’s connected to the grid, you’re probably using natural gas.
Natural gas is lighter than air and disperses quickly if there’s a leak. It burns cleanly, which means fewer carbon emissions compared to coal or oil. It’s also relatively cheap and reliable, which is why it’s still widely used, even as we move towards greener energy sources.
What is LPG?
LPG stands for liquefied petroleum gas, and it’s a mixture of propane and butane. Unlike natural gas, LPG is stored in tanks or bottles and delivered by road. It’s a popular option for homes that aren’t connected to the gas grid – particularly in rural or remote areas across the UK.
LPG is stored as a liquid under pressure and turns into gas when released. It’s heavier than air, which means it can collect at low levels if there’s a leak. It also has a higher energy content per unit than natural gas, so you get more heat from a smaller volume – but it’s generally more expensive.

| Cost | Cheaper | More expensive |
| Typical Use | Homes on the grid | Off-grid properties |
Which is Better for Your Home?
It really depends on where you live and how your property is set up. If you’re connected to the mains gas network, natural gas is usually the cheaper and more convenient choice. There’s no need to worry about running out or arranging deliveries.
On the other hand, if you’re off-grid, LPG can be a practical alternative. It’s cleaner than oil and delivers strong heating performance. Plus, with modern LPG tanks and automatic top-up services, it’s not as much hassle as it used to be.
Environmental Considerations
Neither natural gas nor LPG is carbon-neutral – they’re both fossil fuels. However, they’re less polluting than coal or oil, and they can be part of a transitional energy strategy as the UK moves towards net zero. Some suppliers now offer bioLPG, a renewable version made from plant and waste materials, which is worth looking into if you’re aiming to cut your carbon footprint.
The Bottom Line
Natural gas and LPG might serve similar purposes, but they’re quite different in how they’re delivered, stored, and priced. For most people in urban or suburban areas, natural gas will be the go-to option. But if you’re off the beaten track, LPG offers a flexible and effective solution.
When choosing between them, think about availability, cost, environmental impact, and how much hassle you’re willing to take on. Whichever fuel you use, regular maintenance of your appliances and proper ventilation are key to staying safe and efficient.
FAQs
No, appliances need to be specifically set up for either natural gas or LPG. The gas pressures and combustion characteristics are different, so using the wrong type without adjustment can be dangerous. Some appliances can be converted with a special kit, but this must be done by a Gas Safe registered engineer.
LPG has a higher calorific value, which means it produces more energy per unit than natural gas. However, this doesn’t always mean lower running costs, as LPG tends to be more expensive per litre. Efficiency also depends on how your heating system and appliances are configured.
Most new-builds in towns and cities are connected to the natural gas grid. However, developments in rural areas without mains gas access may be built with LPG heating systems or alternative solutions like heat pumps. Developers usually choose based on cost, infrastructure, and planning requirements.
Yes, LPG appliances can still operate during a power cut, especially gas hobs and standalone heaters. However, LPG boilers or central heating systems with electric controls or pumps may not function unless they have a backup power source.
Yes, if your area becomes eligible for a mains gas connection, you can switch. You’ll need to have the relevant pipework installed and convert or replace your LPG appliances. Contact your local distribution network operator or a qualified installer for guidance and costs.
Yes, LPG is ideal for mobile homes, caravans, and motorhomes because it’s portable and doesn’t require a fixed supply line. It’s commonly used for off-grid leisure vehicles and is widely available in refillable bottles across the UK.
Natural gas prices are usually regulated and billed monthly based on usage via a meter. LPG prices can vary more, as it’s delivered in bulk or cylinders and depends on market rates, supplier contracts, and delivery logistics. Bulk LPG often includes tank rental fees as well.
Propane (commonly used LPG in the UK) remains usable down to around -42°C, so it’s suitable for year-round use. Butane, another type of LPG, doesn’t perform as well in cold temperatures, which is why propane is preferred for outdoor tanks and winter use.
