Installed prices before the grant
The most reliable figures come from the government's Boiler Upgrade Scheme statistics, which record the price of every grant-funded installation from its MCS certificate. They include equipment, labour and VAT, and are before the grant is taken off.
| England and Wales, April to June 2026 | Air source | Ground source |
|---|---|---|
| Lower quarter of jobs | £11,128 | £18,136 |
| Median job | £12,908 | £27,232 |
| Upper quarter of jobs | £15,627 | £42,110 |
| Typical size | 8 kW | 10.5 kW |
Source: DESNZ Boiler Upgrade Scheme statistics, August 2026. The air source median has stayed close to £13,000 for over a year.
Bigger homes need bigger heat pumps
The size of heat pump you need depends on how much heat your house loses, which your installer works out in a room-by-room survey. As a guide, from the same government data:
| Air source size | Usually suits | Median installed cost (2025/26) |
|---|---|---|
| 4 to 6 kW | Flats and small, well insulated homes | £11,494 |
| 6 to 8 kW | A well insulated two or three bedroom home | £12,164 |
| 8 to 10 kW | A typical three bedroom house | £12,686 |
| 10 to 12 kW | A four bedroom house | £13,943 |
| 12 to 16 kW | Larger or older, draughtier homes | £15,365 to £15,496 |
"Usually suits" is a rule of thumb from installer guidance, not part of the government data. Your survey decides the size.
What the grant and VAT take off
- Boiler Upgrade Scheme: £7,500 off an air source or ground source heat pump. Until March 2027 there is an extra £1,500, making £9,000, if your home is heated by oil or LPG and has no mains gas connection. Eligibility criteria apply.
- How it works: your MCS certified installer applies on your behalf and takes the grant off your quote. You do not receive the money yourself.
- 0% VAT: installing a heat pump in your home carries no VAT until 31 March 2027, then 5%. The prices above already reflect this.
| Air source, typical range | Before grant | After £7,500 | After £9,000 (oil or LPG) |
|---|---|---|---|
| Most homes | £11,000 to £16,000 | £3,500 to £8,000 | £2,000 to £6,500 |
| Median | about £13,000 | about £5,400 | about £3,900 |
Our estimate: the government's cost range minus the grant.
Extra work that can add to the price
Most quotes already include a new hot water cylinder, and the government figures above often include radiator changes. Depending on your house, you may also see:
- Larger radiators in some rooms: about £100 to £300 each
- A new hot water cylinder, if not included: about £1,200 to £2,300 fitted
- A new fuse box (consumer unit): about £500 to £1,200
- Loft or cavity wall insulation beforehand: about £400 to £1,800
- Boreholes for ground source: about £4,000 to £6,000 each
Running costs against oil, LPG and gas
Using Ofgem's price cap for October to December 2026 (electricity 26.32p and gas 7.97p per kWh), and heating oil at a range of prices, this is our estimate of the cost to produce 12,000 kWh of heat a year, roughly a three bedroom house. Unit costs only, without standing charges.
| Heating | Cost per year (our estimate) |
|---|---|
| Heat pump, well designed install | about £900 |
| Heat pump, cautious estimate | about £1,130 |
| Mains gas boiler | about £1,060 |
| Oil boiler, oil at 80p a litre | about £1,030 |
| Oil boiler, oil at 97p a litre | about £1,250 |
| Oil boiler, oil at 120p a litre | about £1,550 |
Assumptions: boilers 90% efficient, heat pump efficiency (SCOP) of 3.5 for a good install and 2.8 for a cautious one, heating oil 10.35 kWh per litre. For LPG, Marches Energy Advice, quoting the Energy Saving Trust, puts the typical saving from switching an LPG boiler to a heat pump at about £270 a year, and up to £700 from an older system.
Heat pumps in Shropshire
Much of rural Shropshire is off the gas grid and heated by oil or LPG, which is exactly where heat pumps save the most and where the higher £9,000 grant applies. By June 2026, 987 heat pumps had been installed with the grant in the Shropshire Council area and 198 in Telford and Wrekin.

Common questions
How much is a heat pump after the grant?
Based on the government's figures for real installations, most air source heat pumps cost about £3,500 to £8,000 after the £7,500 Boiler Upgrade Scheme grant, or about £2,000 to £6,500 after the £9,000 grant for oil and LPG homes. Your price depends on the size of the house and how much work is needed.
Who gets the Boiler Upgrade Scheme grant?
Property owners in England and Wales who are replacing a fossil fuel heating system, with an MCS certified installer. It is not means tested. The installer applies for you and takes the grant off your quote. Eligibility criteria apply: see the official guidance.
Is the £9,000 grant still available?
The extra £1,500, which makes £9,000, is available until March 2027 for homes heated by oil or LPG that have no mains gas connection. After that the grant is expected to return to £7,500 for air source and ground source heat pumps.
Is there VAT on a heat pump?
No. Installing a heat pump in your home carries 0% VAT until 31 March 2027. From 1 April 2027 it goes back to 5%.
Is a heat pump cheaper to run than oil?
At current prices, usually yes, and the saving grows when heating oil is expensive. Against mains gas it is roughly break-even on a standard tariff. A good installation that is designed properly for your house makes the biggest difference.
