£9,000
An off-gas home replacing oil with an air-to-water heat pump is in the £9,000 category from 21 July 2026 to 31 March 2027. After that date the standard grant is £7,500.
A typical air-to-water install is often quoted around £10,000 to £16,000 before the grant, so the amount after a £9,000 grant would commonly sit around £1,000 to £7,000. That is a published range, not your quote.

The Boiler Upgrade Scheme is a grant towards a heat pump in England and Wales. The standard amount for an air-to-water or ground source heat pump is £7,500. Oil and LPG homes off the gas grid can be £9,000 until 31 March 2027. Air-to-air is £2,500.
Coal is off the gas grid in ordinary language, but the grant values notice lists a coal replacement at £7,500, not £9,000. A hybrid system is not a grant category. Most new builds are outside the scheme.
The checker uses those published rows. It stays in your browser. The installer applies and Ofgem decides. Read the grant values notice beside any result.

Compare nowOil and LPG grant to 31 March 2027
From 21 July 2026 an off-gas home replacing oil or LPG with an air-to-water or ground source heat pump is in the £9,000 category. After 31 March 2027 the standard grant to describe is £7,500. The checker reads both dates from the data file.
| Category | Until 31 March 2027 | After that date |
|---|---|---|
| Oil or LPG, air-to-water or ground source | £9,000 | £7,500 |
| Gas, electric or coal | £7,500 | £7,500 |
| Air-to-air | £2,500 | £2,500 |
A typical air-to-water install is often quoted around £10,000 to £16,000 before the grant, so the balance after £9,000 is about £1,000 to £7,000. That is a published range, not a quote.
Read what the dates meanWhat is the heat pump grant?
It is a discount on a heat pump installation in England and Wales. You do not receive a separate payment. The installer shows the grant on the quote, applies, and is paid if Ofgem agrees.
The amount follows the heat pump and the fuel you replace. £7,500 is the standard air-to-water and ground source grant. £9,000 is the oil and LPG category for a limited period. £2,500 is air-to-air. Biomass is a separate £5,000 overview, not the default heat pump grant.
It is not guaranteed by this website. One grant applies per property. You have to end up owning the heat pump. Scotland uses Home Energy Scotland, and this site does not sell those enquiries.

How it works
How the grant is worked out
The checker stops first for Scotland, Northern Ireland, a tenant, a hybrid, or a new build. Everyone else in England or Wales is matched to one row on the values notice.
Air-to-air is always £2,500. Air-to-water or ground source is £9,000 only when the fuel is oil or LPG and the uplift window is open. Gas, electric and coal use £7,500. A flat keeps the same amount and adds a note that the system still has to fit.
The cost tool then subtracts that grant from a typical air-to-water band of £10,000 to £16,000. It does not invent a bedroom price, a ground source price, or a running-cost saving.

At a glance
Which amount applies?
£2,500 is every air-to-air row. £7,500 is the usual air-to-water and ground source grant. £9,000 is only oil or LPG, off the gas grid, until 31 March 2027.
After a typical air-to-water install of about £12,000, a £7,500 grant leaves a balance around that published figure minus the grant. The range on this site is £10,000 to £16,000 before the grant, so the balance is wider than one average.

After the grant
Where a typical air-to-water price goes
Energy Saving Trust describes a typical air source installation as about £12,000. Taking off the standard £7,500 grant leaves about £4,500. Taking off £9,000 leaves about £3,000.
The checker’s wider band is £10,000 to £16,000, because quotes sit either side of that typical figure and the scheme average of £13,431 for October to December 2025. Radiators and a cylinder can push a job outside the band. Those extras are not priced here.
This is a guide, not a decision. Your installer applies and Ofgem decides.
