Apply for the Boiler Upgrade Scheme - Climate Hub

Through the Boiler Upgrade Scheme, you could get a grant to cover part of the cost of replacing fossil fuel heating systems with a heat pump or biomass boiler.

You can get one grant per property. Current grants are available for:

£7,500 towards an air source heat pump
£7,500 towards a ground source heat pump (including water source heat pumps and those on shared ground loops)
£5,000 towards a biomass boiler

You’re eligible for a grant if all the following are true. You must:

own the property you’re applying for (including if it’s a business, a second home, or a property you rent out to tenants)
have installed (or plan to install) your new heating system on or after 1 April 2022
be replacing fossil fuel heating systems (such as oil, gas or electric)

You’re still eligible if you’ve already had funding to make your property more energy efficient, for example by insulating it.
