The government’s push to increase clean energy adoption comes amid growing demand for low-carbon alternatives to traditional fossil fuel heating systems. With energy bills rising and climate goals in sharp focus, this extension of the Boiler Upgrade Scheme provides both immediate financial relief and a long-term solution for energy sustainability.
Expansion of the Boiler Upgrade Scheme
Initially, the Boiler Upgrade Scheme provided grants for air and ground source heat pumps, technologies that can help replace fossil fuel-based heating systems like gas boilers. The extension now includes a new £2,500 discount for air-to-air heat pumps, which not only provide efficient heating during winter but also offer cooling during the summer months, bringing added comfort for households year-round.
This new addition is a first in the UK, as air-conditioning systems have not previously been eligible for government funding. According to Martin McCluskey, Minister for Energy Consumers, “Air-to-air heat pumps offer the best of both worlds – keeping you warm in winter while cooling you down when summer comes along.” The grant also covers the installation of heat batteries, which store excess heat for later use, further increasing the appeal of these technologies for families looking to enhance their energy efficiency.
The grants are part of the government’s wider £13.2 billion Warm Homes Plan, designed to help five million families lower their energy bills while meeting climate targets. Over 100,000 applications for heat pumps have already been submitted, with interest rising sharply in 2025. The government’s expansion of the scheme reflects this growing demand for renewable heating solutions, especially as many households look to transition away from gas and oil.
Meeting the Eligibility Criteria
To be eligible for the grant, homeowners must meet several criteria. Firstly, they must own their property and be replacing an existing fossil fuel heating system. The property must also have a valid Energy Performance Certificate (EPC) issued within the past 10 years. The installation must be suitable for the property’s energy needs, typically up to 45kWth for most homes.
The scheme specifically targets off-grid homes in rural areas that use polluting heating systems like oil or LPG boilers, as well as properties with high carbon emissions. Biomass boilers, which are also covered by the scheme, are an ideal solution for homes in remote locations. However, new builds and social housing, as well as properties that have already received government funding for heat pumps, are generally excluded from the scheme.
Homeowners interested in applying for a grant should contact an MCS-certified installer who will submit the application on their behalf. According to the Energy Saving Trust, choosing a certified installer is essential to ensure the installation meets the required standards and that the grant is applied correctly. Once the installation is completed, the installer will apply for the grant through the Ofgem website, and the grant value will be deducted from the total cost.
The Boiler Upgrade Scheme also helps address the UK’s energy efficiency gap, which is key to reducing carbon emissions. As more homes transition to low-carbon heating systems, the government hopes to significantly decrease reliance on fossil fuels, ultimately contributing to the country’s net-zero ambitions.
The expansion of this scheme offers a clear incentive for homeowners to upgrade their heating systems, providing both immediate financial relief and long-term environmental benefits. As more families take advantage of these grants, the UK’s move towards a greener, more sustainable energy future accelerates.
