I’m sure you’re aware of the recent news that has sparked discussions about how we heat our homes and businesses. As we all try to be more sustainable, air source heat pumps have stuck out as being a great solution.
Financial help is available through various government grants and schemes, making air source heat pumps more affordable for homeowners and businesses.
But what are these air source heat pumps, and why does it matter?
Recent changes in the UK Government’s approach aim to make them more accessible and affordable for everyone.

Delaying Mandates for Smooth Transition
One significant change is the UK Government’s decision to push back mandatory air source heat pump installations until 2035. This extension provides households and businesses with essential breathing room they need to adapt to this transformative technology, which has the potential to increase house prices, reduce energy bills, and improve the rating of a home's energy performance certificate. It recognises that substantial changes require a gradual transition to ensure a seamless shift without disruptions.
According to Lord Callanan, Minister for Energy Efficiency and Green Finance, “Today’s changes go even further and will mean even more people could benefit from making the switch, offering them the option for a low-emission, low-cost form of heating their homes.”
Boiler Upgrade Grant
A game-changer is the improvement of the Boiler Upgrade Grant, a programme that supports replacing gas boilers with air source heat pumps. This government grant is increasing from £5000 to £7500, which reduces the upfront costs of purchase and installation when adopting air source heat pump systems. The goal? Encourage more consumers to explore this energy-efficient alternative heating system for their homes.
Whilst the grant for air source heat pump stands at £7,500, other heating systems (ground source heat pumps and biomass boilers) can also benefit from government grants of £5,000.
Recent plans (like the Warm Homes Plan) indicate the scheme's budget is being boosted significantly, with a planned near-doubling for the 2025/2026 financial year to help accelerate uptake.
Lord Callanan affirms, “While a heat pump can be installed for a similar price to installing a gas boiler, the support we’ve put in place means it is an option for more and more households.”
Variable Air Source Heat Pump Grants
To make sure they cater to the diverse needs of households and businesses, the UK Government is introducing variable grants based on property type and existing fuel sources. This tailored approach aims to make air source heat pumps financially feasible for a broader demographic. By recognising consumers’ unique requirements, this initiative's aim is to encourage the widespread adoption of this renewable energy option.
These variable grants directly reduce the overall price of installing an air source heat pump, making it more accessible to a wider range of households.
Simplified Qualification Process
Another change is streamlining the qualification process, although applicants must still meet specific eligibility criteria. They have eliminated the previous requirement for loft or cavity wall insulation before qualifying for air source heat pump grants. This simplification seeks to improve the grant application process and create a more straightforward path to adopting heat pump systems. While insulation is no longer a strict requirement for the grant, having a well-insulated home is still highly recommended, ensuring the air source heat pump runs efficiently and cost-effectively. You must still have a valid energy performance certificate (EPC) that is not more than 10 years old. In addition, the following criteria must be met for grant approval, such as the property type and minimum EPC rating.

£450m Boiler Upgrade Scheme Extended
Looking beyond these immediate changes, it’s essential to consider the bigger picture. Air source heat pumps play a pivotal role in reducing carbon emissions associated with heating. They operate efficiently by harnessing heat from the air or ground, using clean electricity instead of fossil fuels. To further reinforce this transition, government funding has extended the £450 million Boiler Upgrade Scheme until 2028, offering air source heat pump grants.
Homeowners can apply for a source heat pump grant through various government programs, including the Boiler Upgrade Scheme. Other schemes, such as the Renewable Heat Incentive, also provide financial support for renewable heating solutions. The Scottish government is actively promoting heat pump adoption through grants and incentives. In Scotland, interest free loans are available to help cover the upfront costs of heat pump installation, and these can be combined with grants. Households receiving government benefits may be eligible for additional financial support for heat pump installation. Higher grant amounts are available for residents in rural areas and remote areas, with a rural uplift specifically increasing support for those in remote locations. This commitment aligns with the goal of achieving low-carbon heating solutions.
“Heat pumps are a vital tool in cutting the carbon emissions from people heating their homes, while also helping to drive down costs and boosting our energy security,” emphasises Lord Callanan.
Reducing Energy Bills
One of the most compelling reasons to consider an air source heat pump is the potential to significantly reduce your energy bills. Supported by the Boiler Upgrade Scheme and a range of heat pump grants, switching to a low carbon heating system like an air source heat pump can help you cut both your energy costs and your carbon footprint. Thanks to their impressive energy efficiency, air source heat pumps are quickly becoming the go-to choice for homeowners looking to lower their energy consumption and monthly expenses. In fact, according to the government, installing an air source heat pump could save you up to £1,300 per year on your energy bills, depending on your system capacity and how much energy you use.
To access these savings and qualify for heat pump grants, you’ll need a valid Energy Performance Certificate (EPC) and must meet certain energy efficiency criteria. Your EPC rating, which ranges from A (most energy efficient) to G (least efficient), is a key factor in determining eligibility for many heat pump grants. Most schemes, such as the Home Energy Scotland scheme, prioritise support for homes that stand to benefit most from energy efficiency upgrades. Checking your EPC rating is a great first step, and you may find you’re eligible for additional support to help cover the costs of installing an air source heat pump.
Beyond the financial savings, air source heat pumps also play a vital role in reducing carbon emissions and supporting a greener future. By moving away from fossil fuel-based heating systems and embracing renewable energy, you can make your home more environmentally friendly and help the UK meet its ambitious carbon reduction targets. Air source heat pumps can also be paired with other renewable technologies, like solar panels, to create an even more energy efficient and sustainable home energy system.
While the upfront costs of installing an air source heat pump can be significant, there’s a wide range of government grants and financial support available to help. The Boiler Upgrade Scheme offers grants of up to £7,500, making it easier to manage the initial investment. For low income households and those experiencing fuel poverty, the Energy Company Obligation (ECO) scheme provides additional funding for energy efficiency upgrades, including air source heat pump installation. Interest-free loans and other financial support options are also available, helping to make the transition to a low carbon heating system more accessible for everyone.
In summary, installing an air source heat pump is a smart way to reduce your energy bills and carbon emissions, all while benefiting from generous government grants and financial support. By exploring your eligibility and taking advantage of available schemes, you can make your home warmer, more energy efficient, and ready for a greener future.

How have existing heat pump customers responded?
High consumer satisfaction with air source heat pumps isn’t just anecdotal. A remarkable 92% of surveyed heat pump owners expressed high satisfaction with the technology after two winters of use. To ensure that policies align with consumer and industry needs, the government actively seeks input from stakeholders, including certified air source heat pump installers, manufacturers, and suppliers. Working with a certified installer is crucial for successful grant applications and proper installation, making collaboration with these key players vital to shaping effective and responsive policies.
How will this impact the future?
The Future Homes Standard represents another significant milestone. While it won’t dictate specific technologies, it will establish a performance-based benchmark for new homes. They will be built with high energy efficiency and fitted with low-carbon heating systems, effectively banning new fossil fuel boilers. This standard aims to discourage the use of fossil fuel heating in new constructions. The government is showing its commitment to reducing carbon emissions through the promotion of air source heat pumps as low carbon heating systems. Government grants and schemes will continue to support the installation of a new heat pump in both existing and new homes. The latest expected timeline suggests that the regulations will become law in December 2026, with a transition period ending in December 2027, after which all new homes must comply.
The recent changes in the government’s approach to air source heat pumps marks a significant step toward a more sustainable future in heating. By delaying mandates, increasing financial support for heat pump costs, tailoring heat pump grants, and simplifying qualification processes, the government is making it easier for consumers to embrace this eco-friendly technology. Air source heat pumps offer both economic and environmental benefits, and the government’s initiatives are working to bring about a greener future in heating solutions.
