Securing a heat pump grant is a strategic move that puts you in control of your home's energy future. These grants significantly reduce the upfront cost of transitioning to a low-carbon heating system, moving you towards energy independence.
Understanding the heat pump grant: the Boiler Upgrade Scheme
The primary government initiative supporting heat pump installations in the UK is the Boiler Upgrade Scheme (BUS)1. This scheme is designed to encourage property owners to adopt more efficient, low-carbon heating technologies.
What is the Boiler Upgrade Scheme?
The BUS is a government-backed initiative administered by Ofgem, providing upfront capital grants for property owners in England and Wales. Its purpose is to support the decarbonisation of homes and small non-domestic buildings by incentivising the replacement of fossil fuel heating systems with low-carbon alternatives like heat pumps. The scheme is currently scheduled to run until 2030.
How much is the grant for heat pumps?
The BUS offers a substantial grant of £7,500 towards the cost and installation of an air source heat pump or a ground source heat pump. This grant helps to offset the initial investment, making these energy-efficient systems more accessible. For properties heated by oil or LPG without a mains gas connection, an additional £1,500 uplift is available, bringing the total grant to £9,000 for these homes. This uplift is available from 21 July 2026 until 31 March 2027.
Eligibility for the heat pump grant
Understanding the eligibility criteria is crucial for homeowners looking to benefit from the BUS. The grant is designed to support specific property types and ensure installations meet certain standards.
Who can apply for the heat pump grant?
Homeowners in England and Wales can apply for the grant. However, the application process is managed by an MCS-certified installer on behalf of the homeowner, simplifying the process. You cannot apply directly as an individual homeowner; your chosen installer will handle the grant application as part of your installation project.
Property requirements
To be eligible for the grant, your property must have a valid Energy Performance Certificate (EPC). The previous requirement for no outstanding recommendations for loft or cavity wall insulation has been relaxed or removed from 2026 to 2027 onwards. This change aims to make the grant more accessible. New build properties are generally not eligible, with some exceptions for self-builds.
Heat pump requirements
The heat pump installed must be a new system that replaces an existing fossil fuel heating system (such as oil, gas, or electric boilers). All heat pump installations must be carried out by an MCS-certified installer to qualify for the BUS grant. This certification ensures that the installation meets high industry standards for quality and performance. If you're wondering how heat pumps work, they efficiently transfer heat from the air or ground into your home.
Applying for the heat pump grant
The application process for the BUS is designed to be straightforward for homeowners, as the installer takes on the administrative burden.
The installer-led application process
The first step is to find an MCS-certified installer who will assess your home and provide a quote for a suitable heat pump system. Once you agree on a quote, your chosen installer will apply for the grant on your behalf. They will submit the necessary documentation to Ofgem, including details of your property and the proposed installation. The grant amount is then deducted from your final invoice, meaning you only pay the reduced cost of the installation.
What to expect after applying
After your installer applies, Ofgem will review the application. If approved, the grant voucher is issued, and the installation can proceed. The installer will then complete the installation of your heat pump. Once the work is done and registered, Ofgem processes the grant payment directly to the installer. This seamless process ensures you benefit from the reduced cost without needing to manage the grant paperwork yourself.
Types of heat pumps covered by the grant
The BUS specifically targets certain types of low-carbon heating technologies to maximise its impact on decarbonisation.
Air source heat pumps
Air source heat pumps are a popular choice, drawing heat from the outside air to warm your home and provide hot water. They are typically easier to install than ground source systems and are eligible for the £7,500 grant.
Ground source heat pumps
Ground source heat pumps extract heat from the ground using buried pipes. While they generally have higher installation costs due to the excavation required, they are highly efficient and also qualify for the £7,500 grant.
Air-to-air heat pumps
Unlike previous versions of the scheme, air-to-air heat pumps are now eligible for the BUS grant, offering £2,500 towards their cost and installation. These systems typically provide heating and cooling by distributing warm or cool air directly into a room.
Maximising your heat pump grant
Securing the grant is a significant step, but understanding the full financial picture helps you make the most of your investment.
Combining with other incentives
While the BUS is the primary grant, you should also consider other potential incentives that might be available. For example, some local authorities or energy suppliers may offer additional schemes or financing options for energy efficiency improvements. Always check what's available in your area to ensure you're maximising your financial support.
Understanding the overall cost
Even with the £7,500 or £9,000 grant, the total air source heat pump cost can still be substantial. It's important to get multiple quotes from MCS-certified installers and understand what is included in the price. Consider factors like the size of the heat pump, any necessary upgrades to your radiators or pipework, and the cost of insulation improvements if your EPC recommends them. The grant significantly reduces the upfront burden, but it's part of a larger investment in your home's energy future.
Beyond the grant: long-term benefits of heat pumps
Installing a heat pump is more than just a financial transaction; it's a strategic move for long-term energy independence and control.
Energy independence and cost savings
By switching to a heat pump, you reduce your reliance on volatile fossil fuel prices. Heat pumps are highly efficient, converting a small amount of electricity into a large amount of heat, which can lead to lower energy bills over time. This shift provides greater stability and predictability in your energy costs, giving you more power over your household budget.
Environmental impact and future-proofing your home
Choosing a heat pump significantly lowers your home's carbon footprint, contributing to a cleaner environment. As the UK moves towards a decarbonised grid, your heat pump will become even greener. This investment future-proofs your home, aligning it with modern energy standards and increasing its appeal and value in a world increasingly focused on sustainability. It's a tangible step towards a future where energy is abundant and less of a daily concern for homeowners.
