Heat Pump Grants: Where to Access Financial Support

Heat pump grants are available across the UK to help homeowners afford the upfront costs of installation and can make a big difference to those looking to switch to renewable energy.

Heat pumps and other low-carbon heating systems such as biomass boilers and solar thermal panels can help to lower long-term energy bills, compared with natural gas boilers, but they tend to cost more to install. 

Air source heat pumps can cost up to £14,000 to install, while ground source heat pumps cost up to £15,000 depending on size and brand.

Most homeowners will be eligible for at least one type of heat pump grant. Financial assistance in the form of grants and loans can therefore help homeowners make the switch, lower their carbon emissions, and it also helps the government in its push towards net zero emissions by 2050. 

Take a look at which grants are currently available, or will be available soon, to see how much funding you could be eligible for.

Boiler Upgrade Scheme Now Offers Heat Pump Grants

The Boiler Upgrade Scheme officially opened for applications this month, which will provide eligible homeowners with grants up to £6,000 for heat pumps. 

A renaming of the Clean Heat Grant, the Boiler Upgrade Scheme enables homeowners to apply for grants of £5,000 for the purchase of air source heat pumps and biomass boilers, and grants of £6,000 for ground source heat pumps.

The scheme has the capacity to offer 90,000 heat pumps to homeowners in England and Wales.

The Green Homes Grant

The Green Homes Grant, which ran from September 2020 to March 2021, is no longer accepting new applications from homeowners, but you can still apply for funding for improvements such as heat pumps via your local authority. 

Local authorities will grant funding up to £10,000 for air source heat pumps to those in social housing where a home has an Energy Performance Certificate (EPC) rating of D or below, and an annual income below £30,000.

You may also be eligible if you do not possess an up-to-date EPC or earn more than £30,000 a year but are on certain benefits.

To apply, follow the instructions on your local council’s website.

Renewable Heat Incentive

Now no longer accepting new applications, the Renewable Heat Incentive was a government scheme which ran from 2014-2022, and rewarded homeowners who generate and use renewable heating systems to heat their homes.

The RHI paid back the difference in capital cost to install your renewable heating system (against a conventional heating technology) with quarterly payments over a seven-year period.

The amount of payment was calculated according to the heat requirements of your home and the efficiency of the heating system.

The RHI ended earlier this year, when it was replaced by the Boiler Upgrade Scheme. 

Heat the Street

A UK first renewable heating project, Heat the Street will encourage people in Stithians Village in Cornwall to switch to ground source heat pumps. 

Kensa Utilities, which has been awarded a £6m grant by the European Regional Development Fund (ERDF) to part-fund the project, is now looking for 175 private households in Stithians who want to be part of the project. 

Successful applications will switch to a new renewable heating system worth around £20,000 per household, complete with a ground source heat pump, radiators, hot water cylinder and smart thermostat. You can register your interest here (opens in new tab).
