The ECO4 scheme is a UK government grant designed to make households more energy-efficient and environmentally friendly. In the UK, homeowners can upgrade from old, inefficient back boilers to modern air source heat pumps — completely free of charge. These heat pumps are up to 400% more energy efficient, helping you save money while reducing your carbon footprint. These grants are aims to fuel poverty and reduce CO2 emissions.

Eligibility criteria depend on your income, the type of home you live in, your current heating system, and your personal situation. This scheme covers not only ECO4 heat pump grant, but also other renewable and energy-efficient technologies, such as boiler grants and insulation. ECO4 is one of the best ways to improve your household energy efficiency.

Installing a heat pump can cost anywhere from £4,000 to £27,500, including installation. But with the Boiler Upgrade Scheme heat pump grant, you could get up to £7,500 off, which covers most of the cost for an air source heat pump.

A government air source heat pump grant is a smart, more energy-efficient heating system that extracts heat from the outside air — even in freezing situations — and uses it to warm your home and produce hot water. Low-carbon emission that helps reduce your high energy bills while being gentler on the planet. The UK government plans to install 600,000 heat pumps by 2028, a key step toward achieving the nation’s environmental targets.

This air source heat pump grant scheme works well in the UK. They can absorb heat even when temperatures drop as low as –15°C, making them a smart option.

Not everyone can get a free grant through the ECO4 scheme. It’s mainly for people who need the most help. You might qualify if:

An air source heat pump grant takes warmth from the outside air—even when it’s chilly—and uses it to heat your home and hot water. This is an eco-friendly and intelligent temperature controller alternative to traditional gas boilers.

These are step-by-step processes:

Heating Absorption: The outdoor unit draws in air and absorbs heat using a special liquid called a refrigerant.

Compression: A compressor compresses the refrigerant, which means increasing its temperature.

Heat Transmission: The warm air is sent inside to heat your radiators, underfloor heating, or taps.

Reset and Recharge: The refrigerant cools down and relaxes, ready to absorb more heat again.

You are qualified for air heat pump grants under the ECO4 scheme if you meet the simple eligibility criteria and receive benefits. 

Eligibility criteria:

The grant is intended to replace existing fossil fuel heating systems, such as oil, gas, electric, or liquefied petroleum gas (LPG) systems.

You own the home where the heat pump will be installed. In some cases, you may also be eligible for a grant if you live in a rented property. (with your landlord’s permission)

No gas meter installed on your property. You may be eligible for an air source heat pump grant.

The property’s EPC rating is lower than D, E, F, or G.

The boiler is older than 2005 and is of a non-condensing type.

Qualifying government benefits:

Receiving any of the following benefits may make you eligible for a government energy efficiency grant for heat pumps:

• Universal Credit
• Income-Based Jobseeker’s Allowance (JSA)
• Income Support
• Pension Credit
• Child Tax Credit
• Working Tax Credit
• Employment and Support Allowance (ESA)
• Housing Benefit
• Child Benefit (subject to income thresholds)

Air source heat pumps are highly energy-efficient — they can generate more heat energy than the electricity they consume, supported by a low-carbon heating grant in the UK. Here’s a quick breakdown of their performance:

Air-to-water heat pumps: Typically between 200% and 400% efficient, depending on the system and conditions.

Air-to-air heat pumps: Around 300% efficient on average.

Ground source heat pumps: Even more efficient — usually around 350%.

That means for every 1 unit of electricity used, these systems can generate 2 to 4 units of heat — a huge improvement over traditional old boilers. The renewable heat pump grants are becoming a popular choice for making homes warmer, greener, and more cost-effective to heat.

Air source heat pumps aim to be an eco-friendly alternative to traditional gas boilers and electric heaters. Thanks to government grants, you may be able to have one installed for free. Upgrading to an air source heat pump can also improve your home’s EPC rating. Air-to-water systems are more efficient in colder climates, while air-to-air systems may be enough in warmer regions. The heating pump warms your home. 

If you receive tested benefits, you might qualify for a grant that covers the full installation cost. Replacing your old heating system with an air source heat pump can save you up to £1,200 a year on energy bills. Additionally, it will significantly benefit the environment by reducing carbon emissions by 1,650kg annually.

✅ Lower electricity bills (especially off-grid homes)
✅ Cut your carbon CO₂ emissions
✅ Future-proof your home for incoming energy regulations
✅ Quiet, low-maintenance operation
✅ Government-backed funding reduces or removes cost barriers
