Boiler Upgrade Scheme (BUS)
The Boiler Upgrade scheme is installer-led. Installers who are MCS certifiedcan apply for and redeem Boiler Upgrade Scheme vouchers on behalf of property owners.
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 use the grant to replace a heating system in your home or a building used for your business.
Property owners considering installing a heat pump or biomass boiler can apply to the Boiler Upgrade Scheme through an MCS certified installer to help reduce the upfront cost.
The Boiler Upgrade Scheme provides grants to the value of:
- £9,000 off the cost and installation of air-to-water or ground source heat pumps in eligible off-gas grid properties. This is available until 31 March 2027.

- £5,000 off the cost and installation of biomass boilers

You're eligible for a grant if both of 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)
be replacing fossil fuel heating systems - such as oil, gas, electric or LPG (liquefied petroleum gas)
Your installer must commission and install the heat pump within 120 days of applying for the grant or it will not be eligible.
