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 Horsham quote.
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.
Heat pump guide prices in Horsham
These are guide prices for West Sussex, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

Short winter days in Horsham and what they mean
Horsham sees roughly 7 hours 54 minutes of daylight in late December against 16 hours 33 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
Heat pumps in Horsham: questions
Where would the outdoor unit go on a Horsham 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 Horsham home.
How soon can you survey a home in Horsham?
Survey dates depend on how busy installers are in West Sussex. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Crawley as well as Horsham?
Yes. We arrange surveys and installation in Crawley, which is about 7 miles north-east of Horsham, and across West Sussex.
How long does installation take in Horsham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Horsham home states the expected time.
