With the UK moving into even greener times, the government has introduced a number of financial support schemes. These can help make this switch to renewable heating solutions easy.

Thus, with the energy efficiency and eco-friendliness they offer, the Air Source Heat Pump is one of the most popular alternatives to traditional gas and oil heating systems.

With the UK's commitment to a net-zero carbon emission target by 2050, 2025 is most definitely the most exciting year for many.

With several newly available government-backed grants, installing air source heat pumps is now slightly more viable for both landlords and homeowners.

Below are different schemes now open for application here in the UK. The eligibility of the scheme and the benefits that applicants may seek to benefit from, coupled with how one would apply for such a scheme, are also discussed.

What Are Air Source Heat Pumps?

Air source heat pumps are a kind of renewable heating technology that extracts heat from the outside air. Thus, it is internally transferred to the house to heat the building and provide hot water. Unlike gas boilers and burning fossil fuels, ASHPs operate on electricity.

Advantages of Air-source Heat Pumps

• Fewer energy bills: Air-source heat pumps provide ways to economise on the heating of your home. Especially if that home is in an off-grid area.

• Lower carbon footprint: Much cleaner compared to oil or gas boilers. It releases fewer carbon emissions.

• High efficiency: For every 1kW of consumed electricity, an ASHP would be supplying 4kW of heat.

• Government incentives: Free air-source heat pump grants reduce upfront costs for such installations.

Government Schemes for Free Air Source Heat Pumps in 2026

In 2026, there are several government-backed schemes that make air source heat pumps more affordable. And even free of cost for both homeowners and landlords. Major schemes that are available include:

1. Boiler Upgrade Scheme

The Boiler Upgrade Scheme continues into 2026 and beyond for financial support. It makes the replacement of the old fossil fuel boilers with heat pumps attractive to homeowners.

The BUS scheme tries to make the transition to renewable heating systems more economically feasible. It is by giving a considerable share of the installation cost.

There are no strict income criteria compared to other grant schemes under BUS. Hence, making it more accessible to more households.

Key Features: 

Grant amount: £7,500 towards the cost of an ASHP installation.

Eligibility:

• Available to homeowners and small landlords in England and Wales.

• The property has to have an EPC that does not indicate any outstanding recommendations for insulation.

• Replacing oil, LPG, or direct electric heating.

Application Procedure: Homeowners apply through an MCS-certified installer.

Deadline: Though the Boiler Upgrade Scheme runs up to March 2028, funding allocation is reviewed yearly. Hence, an early application for funding might be a better option before any budget revision can be made.

2. ECO4 Scheme

The ECO4 Scheme is a government-funded initiative that requires large energy suppliers to fund energy-efficient home improvements. It is for low-income and vulnerable households.

ECO4 foremost targets low-income families and fuel poverty sufferers to move them onto more efficient and sustainable heating solutions. Other insulation upgrades, solar panels, and other efficiency measures support the heat pumps in these homes.

ECO4 has one more important advantage. It is free for eligible applicants because there are no upfront charges for the process. And it requires no repayment.

The installation will be directly funded and managed by the energy suppliers bound under the scheme. It is to make sure that the process is seamless for the house owner. However, funding for ECO4 is in very high demand. So, the earlier the application, the better.

Key Features:

Grant Amount: Up to 100% of the installation cost for qualified applicants.

Eligibility:

• People in low-income households, including homeowners and tenants.

• Recipients of qualifying benefits, including Universal Credit, Pension Credit, or Housing Benefit.

• Homes that are rated as poorly energy efficient, that is, EPC rating D-G.

Application Procedure:

• Apply through an approved ECO4 installer.

• Eligibility is based on a home energy assessment.

• If approved, installation is scheduled at no charge to the owner.

Deadline: The ECO4 Scheme runs until 31 December 2026. So, it will be providing long-term funding for energy efficiency improvements, including heat pumps, this year too.

3. Home Upgrade Grant (HUG2)

HUG2 is the scheme that provides funding for low-income households, off the grid in England. It is for the replacement or upgrade of traditional heating with a renewable heating solution.

Key Features:

Grant amount: Funding for ASHPs, insulation, and other energy-efficient measures.

Eligibility:

• Households not connected to the gas grid.

• Income threshold applies: households earning below £31,000 per year.

• Homes must have low energy efficiency ratings - EPC D-G.

Application Process:

• Applications are made through local councils in England.

• Eligible applicants get full assessment and free installation upon qualification.

4. Scottish and Welsh Government Schemes

For house owners in Scotland and Wales, more money may be available:

• Warmer Homes Scotland: Grants for heat pumps and insulation.

• Nest Scheme (Wales): Provides free energy efficiency upgrading, including heat pumps.

• Interest-free loans: Available from Home Energy Scotland for those who are not eligible for a grant.

How to Apply for an Air Source Heat Pump Grant

Applying for funding regarding air-source heat pumps is really quite easy.

Step 1: Check Eligibility

• Review the criteria for different schemes.

• Look at your EPC rating at the home.

• Check your income level or benefits status if you are applying under ECO4.

Step 2: Choose an MCS-Certified Installer

• Only MCS-certified installers are eligible to apply for grants on your behalf.

• Use the Ofgem or TrustMark directory in order to choose an approved installer.

Step 3: Apply with an Approved Installer

• BUS and ECO4: Apply via an accredited installer.

• HUG2: Check with your local council to see if funding is available.

• Scottish/Welsh schemes: Apply through Home Energy Scotland or Nest.

Step 4: Home Survey and Approval

• A home energy assessment will suggest the most suitable system.

• Approval usually takes up to 1-2 weeks. It depends on the work demand.

Step 5: Installation and Verification

• Installation will take 1-3 days once approved.

• Final checks ensure follow-through on government regulations.

The Bottom Line

With the UK striving for net zero, the 2026 government-backed schemes now present a very good opportunity. It is for most homeowners and landlords to make a switch to air source heat pumps at little to no cost.

If you are considering renewable heating, check your eligibility. And apply now through a certified installer. Every ASHP being installed today automatically means lower energy bills, lowering carbon footprint, and long-term sustainability for house owners.
