The UK government and energy companies fund several schemes that can help households replace ageing boilers and electric heating with modern heat pumps. The main routes currently include:
The Boiler Upgrade Scheme provides an upfront discount towards an eligible low-carbon heating installation. It is open to eligible property owners in England and Wales and the installer applies on the owner’s behalf. From 28 April 2026, a valid EPC is no longer required to apply, although an existing EPC reference must be supplied where one is available.
Current grants are £7,500 for air-to-water and ground source heat pumps, including water source systems, and £2,500 for residential air-to-air heat pumps. Eligible off-gas-grid homes replacing oil or LPG can receive £9,000 for air-to-water or ground source systems until 31 March 2027.
ECO4 is the Energy Company Obligation scheme that funds energy efficiency upgrades for lower-income and vulnerable households. While commonly associated with insulation, ECO4 can also fund heat pump installation where it forms part of a whole-house improvement plan.
Eligibility usually requires receiving qualifying benefits or meeting local authority flex criteria (low household income confirmed by your council). Properties typically need an EPC of D, E, F or G to qualify.
Air source heat pumps extract heat from outside air and need suitable space for an outdoor unit. Under BUS, an eligible air-to-water system receives £7,500, or £9,000 for a qualifying off-gas-grid property replacing oil or LPG. Residential air-to-air systems receive £2,500. ECO4 and Warm Homes: Local Grant may also fund an air source system where it suits the property and household.
Ground source heat pumps require suitable land for ground loops or access for boreholes. BUS provides £7,500 for an eligible ground or water source system — the same standard grant as an air-to-water system. The grant rises to £9,000 for eligible off-gas-grid properties replacing oil or LPG until 31 March 2027.
Eligibility varies by scheme. In general, you may qualify if:
Eligibility is always subject to scheme rules, available funding, and assessment by an MCS-certified installer or your local authority. Results from our checker are for guidance only.
BUS currently provides £7,500 for eligible air-to-water, ground source and water source heat pumps; £2,500 for residential air-to-air systems; or £9,000 for eligible off-gas-grid air-to-water and ground source installations until 31 March 2027. The grant is deducted from the installer’s quote rather than paid directly to the property owner.
Actual costs vary by property size, complexity, and installer. A professional survey is usually required before work begins and final costs are confirmed.

Yes. Several UK schemes offer funding towards heat pump installation, including the Boiler Upgrade Scheme (BUS) and ECO4. Eligibility depends on your property, heating system, tenure, location and household circumstances.
The Boiler Upgrade Scheme (BUS) provides upfront grants in England and Wales. In 2026, an MCS-certified installer can claim £7,500 for an air-to-water or ground source heat pump, £2,500 for an air-to-air heat pump, or £9,000 for eligible off-gas-grid homes replacing oil or LPG.
Yes. Ground source and water source heat pumps qualify for a £7,500 BUS grant. Eligible off-gas-grid homes replacing oil or LPG may qualify for £9,000 until 31 March 2027. ECO4 and local authority schemes may also help in some cases.
Pensioners may qualify through several routes. Those receiving Pension Credit or other qualifying benefits can access ECO4 funding, while the Boiler Upgrade Scheme is open to all eligible homeowners regardless of age.
Not necessarily. The Boiler Upgrade Scheme does not require benefit receipt. ECO4 typically requires qualifying benefits or local authority flex eligibility, which can include low-income households that are not on benefits.
