Tips on Maximising Government Grants for Heat Pumps 

As more and more people look for alternative heating solutions for their homes, heat pumps are slowly but surely becoming a popular choice.

According to the Heat Pump Association, the heat pump market was predicted to double in 2021, and in 2020 the UK government unveiled a Ten Point Plan for a Green Industrial Revolution, which aims to roll out 600,000 heat pumps into homes per year by 2028. 

The Government is also planning to ban gas and oil boilers from any homes built after 2025, aiming to phase out all gas boilers by 2035. This means if your gas boiler breaks or stops working after 2035, you’ll need to look for a low carbon or renewable heating alternative instead of a boiler.

The cost of installing a heat pump 

Whilst the cost of running a heat pump is comparatively less than a boiler, the same can’t be said for the purchase and installation of an air source heat pump. Cost of buying and  installing a heat pump can cost anywhere from £8,000 and increase to £15,000, depending on project requirements.

To help offset the cost of the purchase and installation of heat pumps, there are a number of Government grants and initiatives available.

From 2022, the following schemes will be available to residents living in the United Kingdom:

Boiler Upgrade Scheme

Part of the Government’s wider Heat and Buildings Strategy, the Boiler Upgrade Scheme launched in April 2022 and aims to help homeowners in England and Wales afford the upfront costs associated with the purchase and installation of heat pumps.

The Government has set aside £450m and will offer grants of up to £5,000 for homeowners who get air source heat pumps installed. If costs of installation exceed the grant, the homeowner will have to pay the difference.

How to apply for Government Grants for air source heat pumps

Once you’ve determined which loan you’re eligible for, it’s time to apply. Applications will differ depending on the type of grant you’re applying for - if in doubt, get in touch with the governing body of the scheme before you send off your application. 


Whilst you’re applying, you should also look for a reputable, MCS accredited installer to install your air source heat pump.

The Boiler Upgrade Scheme

If you’re applying for the Boiler Upgrade Scheme, you can find reputable installers who have registered with Ofgem. If an installer isn’t registered, they can’t access the scheme. 


Once you’ve found an MCS accredited installer,  an assessment will be carried out to check if you’re eligible and that your property is suitable. The installer will apply for the grant on your behalf. The value of the grant is then taken off the price you pay.


With boilers slowly being phased out, it makes sense to look at alternative heating solutions. If you have any questions, browse our Resources centre, or get in touch with an engineer today.
