Grants and rules for heat pumps in England
Homes in Westerham 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

How long is the heating season in Westerham?
On the shortest day Westerham gets about 7 hours 52 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 pumps in Westerham: questions
Where would the outdoor unit go on a Westerham house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Westerham home.
Do you cover Sevenoaks as well as Westerham?
Yes. We arrange surveys and installation in Sevenoaks, which is about 5 miles east of Westerham, and across Kent.
Do I need new radiators for a heat pump in Westerham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Westerham home gives a room-by-room list.
How long does installation take in Westerham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Westerham home states the expected time.
