As the UK continues its journey towards net zero carbon emissions, homeowners are being offered various incentives to make their properties more energy efficient. One of the most talked-about schemes today is the air source heat pump grant, which is part of the broader Boiler Upgrade Scheme—a government-backed initiative that helps households switch to more sustainable and environmentally friendly heating technologies.
Heating accounts for a significant portion of electricity bills in the UK, making this the right time to adopt solutions like air source heat pumps. This highly informative and comprehensive blog will help you understand how the air source heat pump grant works, who qualifies, and how to apply through the Boiler Upgrade Scheme.
What Is an Air Source Heat Pump Grant?
The air source heat pump grant is one of several financial incentives offered through the UK government’s Boiler Upgrade Scheme (BUS) to encourage the adoption of low-carbon heating alternatives and reduce reliance on gas and oil boilers.
Eligible homeowners in the UK can receive up to £7,500 through this grant. The installation of air source heat pumps is especially beneficial for low-income households looking to reduce energy bills and contribute to a greener environment.
Why Are Air Source Heat Pumps a Smart Investment in 2025?
Air source heat pumps extract heat from the outdoor air and use it to warm your home and water—even during the winter months. They not only lower your annual heating costs but also play a crucial role in reducing your home’s carbon footprint.
Here are a few reasons why they’re considered a smart, long-term investment:
- Energy Efficiency: An air-source heat pump can deliver 2 to 3 times more heat energy than the electrical energy it consumes.

- Lower Energy Bills: You can expect significant reductions in your yearly heating expenses.
- Low Maintenance: Once installed, these systems require minimal upkeep.
- Environmental Benefits: Heat pumps rely on renewable energy sources, helping reduce greenhouse gas emissions.

This streamlined process ensures homeowners receive the grant efficiently and without complications.
Air Source Heat Pump Grant Eligibility: 2025 Updates
A number of important changes have been introduced in 2025 to make it easier for homeowners to access government support through the Boiler Upgrade Scheme and move towards low-carbon heating. The latest updates include:
- Removal of the 1-metre boundary rule
Air Source Heat Pumps (ASHPs) can now be installed closer to property boundaries, making them a more practical option for many households.
- Increased allowable unit volume for houses
The permitted size of ASHP units for houses has increased from 0.6m³ to 1.5m³, allowing for more efficient and higher-capacity systems.
- Permission for two units on detached homes
Detached properties can now accommodate two ASHP units, offering greater flexibility for homes with higher heating demands.
- More flexible placement rules
Installations are now permitted in more locations, including some properties that face directly onto a highway.
These changes significantly reduce the barriers to installation and make 2025 an ideal time to take advantage of available grants and transition to a more sustainable heating system.
