Air Source Heat Pump Grant
Your Gateway to Energy Efficiency
Air source heat pumps (ASHPs) use the warmth in the air to heat your home efficiently – helping reduce both energy bills and carbon emissions. With rising energy costs, government energy support programs like the Air Source Heat Pump Grant (under the ECO4
Scheme) make switching more affordable than ever.
Air source heat pump grant applications under ECO4 are now open for: July 2025

How to Apply for an Air Source Heat Pump Grant
Before diving into the application process, it’s essential to know if you qualify for the Air Source Heat Pump Grant. Eligibility often depends on factors like your location, income level, and the current heating system in your home.
Understanding how grant funding works is crucial. Government funding is designed to reduce the financial burden on UK homeowners and are often prioritized on a first-come, first-served basis. Eligibility requirements can vary, so it’s important to check the specific criteria for your area.

Step 1 – Eligibility check
First, answer a few questions to find out if you qualify for the grants available for air source heat pumps.

Step 2 – Survey
Once you’re confirmed eligible, we’ll schedule a home visit so that we can determine whether an ASHP can be applied to your circumstance.

Step 3 – Installation
As soon as your home is approved for grants available for heat pump installation, all that’s left to do is to agree an ECO4 Scheme installation date!
Why Apply for a Grant?
Air source heat pumps serve as an efficient and sustainable alternative for home heating. Opting for a heat pump with UKES over a traditional gas boiler or electric heating offers several advantages:
Lower Energy Bills
Heat pumps are generally more energy-efficient, leading to reduced utility costs.
Reduced Carbon Footprint
Unlike gas boilers, heat pumps have a lower impact on the environment, helping you contribute to greenhouse effect mitigation.
100% free
Government grants are used to subsidise full cost of installing heat pumps, making them financially accessible for those in need of free grants for low-income families.
Insulation Benefits
Grants, including Energy Company Obligation (ECO4), often extend to additional energy-saving measures like cavity wall insulation, maximizing your home’s overall efficiency.
Alternative Options
If a heat pump isn’t suitable for your property, grants may also cover other sustainable options like air source heat pumps and solar panels, storage heaters, back boiler removal grant or loft insulation and cavity wall insulation, among other insulation grants.

Case Studies and Real-Life Examples
Take Mark, for example—a UK farmhouse owner who also rents his place on Airbnb. With help from the air source heat pump grant and the boiler upgrade scheme, he swapped his old heating setup for a heat pump and even got free solar panels thrown in. Before the ASHP went in, he had some insulation work done to make sure everything ran as efficiently as possible.
Thanks to the renewable heat incentive, Mark was able to make some serious energy efficiency improvements. A big chunk of the cost was covered by the ECO Scheme, so it didn’t hit his wallet too hard.
Now he’s saving about £1,200 a year on energy costs and has cut his carbon footprint by 40%. His farmhouse, which used to rely on the gas grid, now runs on clean heat energy—a solid example of how switching to renewable energy can really pay off.

Expert Opinions and Tips
Thinking about switching to a low carbon heating system? There’s solid research backing Air Source Heat Pumps (ASHPs) as a smart move. In fact, a study from 2019 showed that using heat pump heating isn’t just good for cutting carbon and air pollution—it also helps ease pressure on the power grid and supports better energy management overall. That’s why many experts see ASHPs as a powerful heat solution in the fight against climate change.
“Increasing the share of heat pump heating is advantageous in terms of carbon emissions, air pollutants emissions, benefits to the power grid, and economic operation”
“20% of the expected reduction of electricity consumption is converted into increased comfort in the homes, including extended heating areas, keeping a higher temperature and a longer heating season”
According to research by K. Gram-Hanssen, ASHPs can cut electricity use by up to 20%. Homeowners often turn those savings into more comfort—like larger heating areas or longer heating seasons.
When it comes to space heating, ASHPs offer a more energy-efficient option compared to older systems like biomass boilers. They also help create a more comfortable home overall. Backed by strong research, an air source heat pump could be a smart, sustainable upgrade for your home.








Are Air Source Heat Pumps Worth it?
Air source heat pump grants provide a sustainable alternative to traditional gas boilers and electric heating systems, covering the total cost of installation.
Meeting means-tested benefit criteria can make you eligible for these grants, aimed at achieving minimum efficiency levels. Whether you’re considering a heat pump or other heating solution, these grants offer financial relief for loft or cavity wall installations as well.

Air Source Heat Pump FAQ
Is Air Source Heat Pump Grant Available Under ECO4?
Yes, the energy efficiency scheme run by the government includes measures installed by trusted professionals – like us – who are approved by leading energy suppliers. That means the work meets strict quality standards, so you can feel confident in the results.
And if your current energy provider isn’t on the list, don’t worry—you might still qualify through Government Energy Grants. Just fill out our short form, and we’ll check if you meet the criteria for the Energy Company Obligation grant.
It could be your chance to get a heat pump government grant and boost the energy efficiency of your home – all at no cost to you.
Why is my electric bill so high with an air source heat pump?
Electric bills may rise if your system capacity isn’t matched to your home or if you’re still using panel heaters alongside it.
Without efficiency upgrades like outstanding loft insulation, your heat pump installation works harder to provide heating.
Ensure you have a valid Energy Performance Certificate (EPC) and get impartial advice from your chosen installer.
Also, check if your heat pump is fully replacing your existing fossil fuel system, as running both can increase costs.
What are the disadvantages of an air source heat pump?
The main drawbacks include upfront costs, lower performance in cold weather compared to ground source heat pumps, and the need for space for the external unit. If you’re off-grid, water source heat pumps or ground source heat options may be more suitable. However, grant funding under the Energy Company Obligation scheme and Boiler Upgrade Scheme can reduce remaining costs, especially for low income households.
How much does an air source heat pump installation cost?
Typical heat pump installation costs range from £7,000 to £13,000. However, financial support like the Boiler Upgrade Scheme and especially ECO4 scheme may cover the full cost or offer a rural uplift to reduce remaining costs. Eligibility depends on factors like your EPC rating, whether you’re fully replacing an existing heating system, and whether you claim any benefits.
Are grant air source heat pumps any good?
Yes, when installed properly by a certified chosen installer, they’re an efficient way to provide heating. With financial help covering most of the upfront costs, grant-funded systems are a smart choice—especially for low income households. Many include energy efficiency upgrades and work well alongside ground source or water source heat pumps. Just ensure you have a valid EPC certificate and follow scheme administrator guidance.
ECO4 is a government initiated scheme overseen by Ofgem
