QUICK ANSWER
Which Heat Pump Grant Could You Get?
In England and Wales, the main government support is the Boiler Upgrade Scheme. The amount depends primarily on the technology being installed and, for the enhanced grant, the heating system you are replacing.
£7,500 Standard Grant
For eligible air-to-water and ground source heat-pump installations in England and Wales.
£9,000 Oil & LPG Grant
For qualifying off-gas-grid properties replacing oil or LPG with an eligible air-to-water or ground source heat pump.
£2,500 Air-to-Air Grant
For eligible residential air-to-air heat-pump installations that meet the Boiler Upgrade Scheme requirements.
The quickest way to identify the likely grant
If you are installing a conventional air-to-water heat pump, start with £7,500. If you are off the mains gas grid and currently heat the property with oil or LPG, check whether the enhanced £9,000 amount applies.
If you are considering an eligible whole-home air-to-air heating system, the available BUS grant is £2,500.

What Is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme, usually shortened to BUS, is the main government scheme supporting low-carbon heating installations in England and Wales.
It can provide funding towards eligible:
Air-to-Water
The type most UK homeowners mean when they talk about an air source heat pump connected to radiators and hot water.
Ground & Water Source
Eligible ground-source and water-source heat-pump systems can also receive BUS support. If you are considering this route, see our ground source heat pump cost guide for how groundworks and boreholes affect the budget after a grant.
Air-to-Air
Eligible residential air-to-air heating systems have been included in BUS since April 2026.
Biomass
Biomass boilers can qualify in more limited circumstances where the scheme conditions are met.
You normally do not claim the money back yourself
BUS is an installer-led scheme. An appropriately certified installer normally applies for the voucher and redeems it after the installation.
The grant should be passed to you as an upfront reduction in the price rather than asking you to pay the grant amount first and reclaim it later.
THE STANDARD GRANT
£7,500 Towards an Eligible Heat Pump
Most eligible air-to-water and ground source heat-pump installations in England and Wales currently receive £7,500 through the Boiler Upgrade Scheme.
The grant reduces the installation cost, but you should still compare the complete specification behind different quotations.
£9,000 Heat Pump Grant for Oil and LPG Homes
From 21 July 2026 until 31 March 2027, certain off-gas-grid properties replacing heating oil or LPG can receive an enhanced £9,000 grant.
1. Off the Gas Grid
The property must not have a mains gas connection for the enhanced grant to apply.
2. Currently Heated by Oil or LPG
The £9,000 amount specifically targets eligible properties replacing heating oil or LPG.
3. Eligible Heat Pump
The enhanced amount applies to eligible air-to-water or ground source systems — not air-to-air.
4. Normal BUS Rules Still Apply
Being off-grid and using oil or LPG does not override the scheme’s wider property, system and installation requirements.
£2,500 Air-to-Air Heat Pump Grant
Eligible residential air-to-air heat-pump installations in England and Wales can now receive £2,500 through BUS.
This is not simply a £2,500 air-conditioning grant
Reversible air-to-air systems can provide heating and cooling, but installing a single cooling unit in one room does not automatically qualify for government funding.
The installation must be an eligible air-to-air heat-pump system that meets the Boiler Upgrade Scheme’s residential heating and technical requirements.
Who Can Usually Get a Boiler Upgrade Scheme Grant?
Exact eligibility depends on the property, the existing heating system and the replacement technology, but the main requirements can be summarised quite simply.

Who Usually Cannot Get a BUS Grant?
Most Standard New Builds
Ordinary developer-built new properties generally do not qualify, although eligible self-build properties can.
Social Housing
Social housing is generally outside the normal BUS property-owner route.
Existing Low-Carbon Heating
BUS cannot normally be used simply to replace an existing low-carbon heating system.
Hybrid Heat Pumps
Fossil-fuel hybrid heat-pump systems are not supported through the standard BUS grant.
How Do You Apply for a Heat Pump Grant?
You normally do not complete the main voucher application yourself. The installer handles most of the process.
1. Check Eligibility
Establish which grant route appears relevant to your property and existing heating system.
2. Compare Installers
Obtain quotations from appropriately certified installers and compare both price and system design.
3. Property Assessment
The installer assesses heat loss, emitters, hot water and other requirements before specifying the system.
4. Review the Quote
Check the proposed equipment, total cost and BUS grant amount before proceeding.
5. Installer Applies
The installer applies to Ofgem for the BUS voucher and you confirm the required consent and property details.
6. Installation & Redemption
After the eligible installation is completed, the installer redeems the voucher.
You should not normally finance the grant yourself
The grant value should be reflected in the amount you pay rather than requiring you to fund the full installation and wait for a government reimbursement.

Heat Pump Cost After the Grant
These examples simply show what remains after deducting the fixed BUS grant from an example installation quotation.
| Example Installation | After £7,500 | After £9,000 |
|---|---|---|
| £10,000 | £2,500 | £1,000 |
| £12,000 | £4,500 | £3,000 |
| £15,000 | £7,500 | £6,000 |
| £18,000 | £10,500 | £9,000 |
What Can You Still Need to Pay for After the Grant?
A large grant does not necessarily make the entire project free. The final quotation depends on the work your home requires.
Radiators
Some emitters may need enlarging or replacing so the property can be heated efficiently at lower flow temperatures.
Radiator Guide →Hot-Water Cylinder
Homes moving away from a combi boiler may need a suitable cylinder and associated plumbing work.
Electrical Work
Cabling, isolators, consumer-unit work or other electrical changes may be required.
Pipework & Controls
Existing heating layouts can require pipework alterations, controls and additional commissioning work.
Paying for the rest: the Warm Homes Loan Scheme
The government-backed Warm Homes Loan Scheme offers low- and zero-interest loans through approved lenders for heat pumps, solar panels and home batteries anywhere in the UK. Its September 2026 rules planned an initial consumer launch phase from September 2026, so check which lenders are currently taking part.
A heat pump loan can sit alongside a Boiler Upgrade Scheme grant and cover the cost above it. Loan caps include £20,000 for an air-to-water heat pump and £15,000 for solar and battery storage. Products and installers must be MCS certified. Interest rates vary by lender and depend on credit checks.
Heat Pump Grants in Scotland
Scotland does not use the Boiler Upgrade Scheme. Homeowners instead have access to the Home Energy Scotland Grant and Loan.
Up to £7,500 Grant
Available towards qualifying heat-pump installations under the Scottish scheme.
Optional Loan Funding
Additional interest-free loan funding can be available towards eligible installation costs.
Rural Uplift
Qualifying rural and island properties can receive an additional £1,500 grant uplift.
Eligibility differs from BUS. The main homeowner route applies to an existing Scottish property that is the applicant’s only or principal private residence.
Heat Pump Grants in Northern Ireland
Northern Ireland does not participate in the Boiler Upgrade Scheme, so homeowners should not assume the £7,500 BUS grant applies.
Heating and energy-efficiency support is provided through separate Northern Ireland programmes, with eligibility depending on the household and the measure being installed.
Check the current official support available before making financial assumptions about a heat-pump project.
Does a Grant Mean a Heat Pump Will Be Cheaper to Run?
No — the grant and the running cost are separate questions.
A grant reduces the upfront installation cost. It does not change how much electricity the heat pump uses once installed.
Running costs depend on property heat loss, system design, seasonal efficiency, flow temperature, radiator sizing, controls, hot-water usage, commissioning and your electricity tariff.
