Are you considering an LPG boiler for your home? If your property is not connected to the mains gas network, LPG can be one option for heating your home and hot water.
As with any heating system, there are advantages and disadvantages to consider. Fuel costs, storage requirements, installation work and servicing all need to be taken into account before choosing an LPG boiler.
What Is LPG?
LPG stands for liquefied petroleum gas. It is a fuel used for heating, cooking and other applications.
For domestic heating, LPG is stored in a tank at the property and supplied to the boiler when needed. Unlike a natural gas boiler, an LPG boiler does not rely on a mains gas connection.
How Does an LPG Boiler Work?
An LPG boiler burns LPG to heat water. The heated water can then be circulated through radiators and supplied to taps for domestic hot water.
The main difference between an LPG boiler and a natural gas boiler is the fuel supply. LPG requires on-site storage, while a natural gas boiler is connected to the mains gas network.
Pros of LPG Boilers
No Mains Gas Connection Required
One of the main benefits of LPG is that it can be used in properties that are not connected to the mains gas network.
This can make LPG a practical option for some rural or off-grid properties where natural gas is unavailable.
Efficient Heating
Modern boilers can use LPG efficiently to provide heating and hot water. Actual running costs will depend on the boiler, property, heating controls and current LPG prices.
Flexible Fuel Storage
LPG can be stored on the property, so homeowners do not need a mains gas connection. The size and type of tank will depend on the property and installation requirements.
Cons of LPG Boilers
LPG Fuel Costs Can Vary
LPG prices can change, so running costs are not fixed. LPG should not automatically be considered cheaper than mains gas.
The cost of fuel, delivery charges and household energy use all affect the overall cost of running an LPG heating system.
You Need Space for an LPG Tank
An LPG boiler needs a suitable fuel storage tank. This takes up space, and the tank must be installed and maintained safely.
The available space, tank type and installation requirements should be considered before choosing LPG heating.
Fuel Deliveries Need Planning
Unlike a mains gas supply, LPG stored on the property can run out. Homeowners therefore need to monitor their fuel level and arrange deliveries.
Some systems can use tank monitoring equipment to help with this, but delivery still needs to be planned.
Installation Can Cost More
An LPG heating system requires more than the boiler itself. The installation may also involve an LPG storage tank, pipework and other site-specific work.
The total cost will depend on the property and the equipment required.
Regular Servicing Is Important
Regular servicing helps keep the boiler operating safely and efficiently. It also gives an engineer an opportunity to identify developing faults before they become more serious.
If your LPG boiler develops a fault, use a suitably qualified engineer to diagnose and repair it.
LPG Boilers and UK Heating Regulations
In England, the Future Homes and Buildings Standards were published in March 2026. The relevant regulations come into force from 24 March 2027, subject to transitional arrangements. The standards are intended to ensure new homes use low-carbon heating and higher levels of energy efficiency.
This is different from saying that homeowners have to remove an existing LPG boiler because of a 2025 ban.
If you are considering replacing an LPG boiler, check the current requirements that apply to your property and the type of building work being carried out.
Is an LPG Boiler Right for Your Home?
LPG can be useful where mains gas is unavailable, but it comes with additional considerations. You need suitable space for fuel storage, need to arrange deliveries and should allow for changing fuel prices.
Before choosing an LPG boiler, consider the installation requirements, ongoing fuel costs and servicing needs for your property.
If you are also dealing with faults or symptoms from your existing heating system, see our guide to common boiler problems for more information.
