Conversion Kits

Switch fuel types with confidence using our boiler conversion kits. Whether you're converting from natural gas to LPG or adjusting for off-grid installations, these kits provide the correct parts to get the job done safely and efficiently. Each boiler conversion kit is designed for a specific model or range, helping ensure full compatibility and compliance with manufacturer requirements. Always check the boiler spec before ordering, and pair with the right flue or control accessories to complete the install. Plenty of our gas boilers are LPG already, so we have options whether you're after a new boiler or just need to update an existing one to LPG. 

Q: What is an LPG conversion kit for a boiler?

A: An LPG conversion kit allows a natural gas boiler to be safely adapted for use with liquefied petroleum gas (LPG). This typically includes new gas jets or injectors, a data badge or conversion label, and setup instructions to ensure the boiler runs correctly on bottled gas. It's essential for properties that aren't connected to the mains gas grid.

Q: Which boilers are compatible with LPG conversion kits?

A: Not all boilers can be converted. However, many models from leading manufacturers, such as Ideal,  and Intergas offer LPG conversion kits for their combi and system boilers. Always check the boiler’s manual or manufacturer website for LPG compatibility before purchasing a kit, some are LPD ready.

Q: Is it worth converting to LPG?

A: If your property is off-grid or has no access to mains gas, converting to LPG can be a practical and efficient solution. LPG offers lower upfront costs compared to full renewables and allows you to keep a familiar gas boiler setup with relatively low disruption. It's especially popular in rural areas. We also stock oil boilers, which can serve as an alternative if you aren’t connected to mains gas. 

Q: Can I convert a combi boiler to a system boiler or vice versa?

A: In most cases, switching between boiler types involves more than just a kit – it requires a full system redesign, including changes to the pipework and controls. It’s not just a conversion of fuel supply. If you're looking to switch between boiler types, you’ll need a whole new boiler. Speak to a qualified installer or our team for guidance.

Q: How much does it cost to convert a boiler to LPG?

A: Costs will depend on your boiler model and the complexity of the install. Conversion kits are typically £30–£80, but installation by a Gas Safe engineer is required and may add £100–£300 depending on your location and boiler setup.

Q: Do you need a Gas Safe engineer to fit a conversion kit?

A: Yes, all boiler conversion kits must be fitted by a qualified Gas Safe registered engineer, who’s also certified to work with LPG appliances. This ensures the conversion is safe, legal, and meets Building Regulations.
