Grants and rules for heat pumps in England
Homes in Chislehurst 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 Chislehurst?
On the shortest day Chislehurst gets about 7 hours 50 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 Chislehurst: questions
Do I need new radiators for a heat pump in Chislehurst?
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 Chislehurst home gives a room-by-room list.
How long does installation take in Chislehurst?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Chislehurst home states the expected time.
Can you service a heat pump in Chislehurst that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Chislehurst, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Chislehurst?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
