Air Source Heat Pump Grants
Take advantage of air source heat pump grants while they are available in the UK! Air source heat pumps are a modern, eco-friendly alternative to traditional gas boilers, offering high efficiency heating and lower energy bills. They work by extracting heat from the outside air even in cold weather and using it to heat your home and hot water. Through the ECO4 scheme, Cucumber Eco helps eligible households access fully funded air source heat pump grants, covering everything from assessment to installation.
We’ve supported countless property owners in switching to cleaner, more sustainable heating- reducing bills while preparing homes for the future.
Air source heat pumps are ideal for homes looking to move away from fossil fuel systems. They offer consistent, controllable warmth and work especially well in well insulated properties. For landlords, they’re a smart investment in long-term energy efficiency. For tenants, they offer lower running costs and a more comfortable living environment, all without paying a penny upfront.
We make the switch to an air source heat pump hassle-free and cost-free:

What is an air source heat pump?
An air source heat pump (ASHP) extracts heat from the outside air and uses it to warm your home and hot water. It’s a low-carbon alternative to traditional gas or oil heating and is highly efficient, even in colder weather.
How does an air source heat pump work?
It absorbs heat from the outside air (even in winter), then boosts it to a higher temperature using electricity. This heat is then used to warm your home and hot water.
Is it really free through the ECO4 scheme?
Yes, if you meet the eligibility criteria, the full cost—including the pump, installation, and controls—is covered. No hidden charges, ever.
Is it suitable for my home?
Air source heat pumps are most effective in homes with good insulation. Our assessors will review your property to make sure it’s the right fit—and we can combine it with insulation upgrades where needed.
Can I get an air source heat pump for free?
Yes - under the government’s ECO4 scheme, eligible households can have an air source heat pump installed at little or no cost. In most cases the system is fully funded, although sometimes a small contribution may be required depending on property needs.
Who qualifies for an ECO4 heat pump grant?
You may be eligible if:
You receive means-tested benefits such as Universal Credit or Pension Credit.
You are referred under ECO Flex by your local council (for low-income or vulnerable households not on benefits).
Your home has an EPC rating of D–G and is suitable for a heat pump system.
Do I need to own my home to apply?
Homeowners can apply directly.
Private tenants can qualify with landlord permission.
Social tenants may be eligible, subject to EPC rating and landlord approval.
What are the benefits of an air source heat pump?
Lower energy bills compared to older, inefficient heating systems.
Reduced carbon emissions.
Eligibility for government funding.
Long lifespan, with proper maintenance.
How long does installation take?
Most installations take two to four days, depending on property size and system complexity. A full home survey is carried out beforehand to ensure suitability.
Do I need underfloor heating for a heat pump?
Not always. Air source heat pumps work best with low-temperature systems such as underfloor heating or oversized radiators, but many properties can be adapted during installation.
What guarantees come with ECO4 heat pumps?
All installations must meet PAS 2030/2035 standards and be carried out by TrustMark-registered installers. Heat pumps typically come with manufacturer warranties of 7–10 years, plus additional installer guarantees.
How does ECO4 support air source heat pumps compared to other schemes?
ECO4: Funds installations for eligible low-income and fuel-poor households.
Boiler Upgrade Scheme (BUS): Offers grants of up to £7,500 towards heat pumps for homeowners not qualifying under ECO4.
