Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Sevenoaks quote.
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.

Designing for Sevenoaks's winters
On the shortest day Sevenoaks 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 Sevenoaks: questions
How long does installation take in Sevenoaks?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sevenoaks home states the expected time.
Can you service a heat pump in Sevenoaks that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Sevenoaks, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Sevenoaks 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 Sevenoaks home.
How soon can you survey a home in Sevenoaks?
Survey dates depend on how busy installers are in Kent. We offer the next available dates when you enquire and confirm them in writing.
