How to apply for a £7,500 heat pump grant in the UK (2025 Guide)

Thinking of futureproofing your heating but unsure if an air source heat pump grant is available?

The UK heat pump grant, known as the Government's Boiler Upgrade Scheme, offers a £7,500 grant to help homeowners cover part of the cost of installing a heat pump.

These grants will help you with the upfront costs. Starting in April 2022, the scheme is currently running until April 2028, so you still have time to take advantage of the £7,500 heat pump grant. This will cover both ground source and air source heat pumps.

So why should you apply? A UK government heat pump grant is designed to partially cover the cost of the heat pump system and its installation and make it more affordable to move away from a fossil fuel heating system (typically a gas boiler) and onto a more energy efficient, low carbon heating system.

This short guide helps you to understand if you are eligible for a heat pump grant.  The good news is– you probably are!

The step-by-step process to applying for a heat pump grant in the UK

Firstly, the Boiler Upgrade Scheme is specifically for homeowners residing in England and Wales - Scotland and Northern Ireland have different financial support offerings for their householders.

To be eligible for the Boiler Upgrade Scheme and access a heat pump grant in England and Wales, you must meet the following criteria:

1. Own your home – You must own the property where you want to install the heat pump – the heat pump grant isn’t available to those in social housing and new build properties
2. Replace fossil fuel with renewable heating – You must be replacing a fossil fuel system with a renewable heating system, such as a heat pump (either ground or air source). You aren’t eligible if you are replacing an existing heat pump or renewable system
3. Valid EPC – You must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation. You can check this at https://www.gov.uk/find-energy-certificate if you’re unsure. There are some exemptions from Ofgem, you can read about them here
4. Accredited installer -You must use a Microgeneration Certification Scheme (MCS) accredited installer to carry out your heat pump installations in order to secure the heat pump grant –  all of our trusted, local installers are MCS accredited

How much help can you get with a UK government heat pump grant?

The grant of up to £7,500 is a considerable amount of money to help you with the cost of buying and installing a heat pump.

Depending on the type and size of heat pump you choose, and the necessary changes needed to your house to make it efficient, anew system can cost around £13,000 on average to install.

So securing a heat pump grant can certainly supplement a large chunk of this cost, although it’s unlikely that it will cover the full cost of installing a heat pump.

Is there anything a UK heat pump grant won't cover?

1. Hybrid systems – You cannot get a government heat pump grant for a hybrid system e.g. a combination gas boiler and air source heat pump

2. Low carbon heating systems– You cannot get a heat pump grant to replace a low carbon heating system e.g. electric boiler, biomass boiler or solar heating system

3. Bullet 3 – The system you install must meet certain standards, such as minimum efficiency levels. Our installers will help advise on this point

4. Bullet 3 The heat pump system you choose must have a maximum capacity of 45kWth (for context homes in the UK would typically need between 4kWth and 16kWth)
