Understanding Air Source Heat Pump Funding in the UK

Air source heat pumps extract warmth from the outside air—yes, even when it’s frosty. They can provide heating and hot water with up to 300% efficiency compared to old gas boilers. But the upfront cost can be daunting. Enter air source heat pump funding, the government’s tool to cut that bill.

By 2026, the UK government aims to install hundreds of thousands of heat pumps per year. Schemes like ECO4, the Boiler Upgrade Scheme, and local grants make this technology affordable. In the sections below, we’ll show you how to tap into these pots of money.

What Is an Air Source Heat Pump?

  • Outdoor unit absorbs ambient heat—even at –15 °C.
  • Refrigerant carries warmth to a compressor.
  • Heated refrigerant sends heat indoors through radiators or underfloor heating.
  • Cycle repeats, offering consistent warmth.

Imagine it as a giant fridge in reverse.

Why Is Funding Available?

  • Reduce household carbon emissions.
  • Lower national gas consumption.
  • Support fuel-poor households.
  • Hit 2050 net-zero targets.

Grants make heat pumps affordable for everyone—no more choosing between heating and eating!


Government Grant Schemes Overview

ECO4 Grants

The ECO4 programme helps low-income households switch to efficient heating. You could get up to £7,500 off an air source heat pump installation, plus free loft or cavity wall insulation.

Key points:
– Must receive qualifying benefits.
– EPC rating D, E, F, or G required.
– Insulation upgrades included if needed.

Boiler Upgrade Scheme (BUS)

Replaced the domestic RHI. Offers £5,000 off approved heat pumps. Open to owner-occupiers and landlords.

Highlights:
– Claim voucher before installation.
– Work must be done by MCS-certified installer.
– Available until March 2028.

Local Authority and Devolved Government Grants

Councils in Scotland, Wales, and Northern Ireland run their own incentives.
Check your local authority website—some offer additional cash for pairing heat pumps with solar PV.


Eligibility Criteria for Grants

Household Income and Benefits

To qualify for ECO4, you need one of:
– Universal Credit
– Pension Credit
– Income-based Jobseeker’s Allowance

…and more.
Lower-income, higher grant.

Property Type and EPC Rating

  • EPC D–G homes get priority.
  • Off-gas-grid properties often receive higher grants.

Got a newer home? Don’t despair—BUS is open to gas-grid premises too.


How to Apply for Air Source Heat Pump Funding

Step 1: Check Your Eligibility

It’s the ultimate eco combo.
