What to know about heat pump grants in Warminster

Grants and rules for heat pumps in England
Homes in Warminster can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

How long is the heating season in Warminster?
On the shortest day Warminster gets about 7 hours 53 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump grants in Warminster: questions
How long does a heat pump survey take in Warminster?
A home survey in Warminster usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
What size heat pump does a Warminster home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Warminster home.
Can you service a heat pump in Warminster that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Warminster, whoever fitted them. Tell us the make and model when you book.
Who applies for the Boiler Upgrade Scheme?
In England and Wales, the MCS-certified installer applies to Ofgem for the Boiler Upgrade Scheme on your behalf, and the grant is deducted from your quote. Ofgem then contacts you as the property owner to confirm the details. Your quote names the MCS-certified installer for your job, so you know who is making the application.
How much is the heat pump grant?
It depends on where you live. In England and Wales, the Boiler Upgrade Scheme pays £7,500 towards an air-to-water heat pump, or £9,000 when replacing oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers up to £7,500, plus a rural uplift and an optional loan. Northern Ireland has no dedicated grant at present.
