About the Scheme

Government Funding for Cleaner Heating

The Boiler Upgrade Scheme provides financial support towards installing an air source heat pump, helping reduce the upfront cost of switching to renewable heating. Our experienced team will guide you through every step, ensuring a smooth and hassle-free installation.

Administered through Ofgem and available to homeowners in England and Wales, the BUS grant is applied directly to the cost of installation — meaning you never need to claim it back yourself. Proximus Solutions handles the application on your behalf as an approved MCS-certified installer.
