Grants and rules for heat pumps in England
Homes in Crawley 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.

Short winter days in Crawley and what they mean
Crawley sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 34 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 Crawley: questions
Can you service a heat pump in Crawley that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Crawley, whoever fitted them. Tell us the make and model when you book.
Do you cover Horley as well as Crawley?
Yes. We arrange surveys and installation in Horley, which is about 4 miles north of Crawley, and across West Sussex.
Where would the outdoor unit go on a Crawley 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 Crawley home.
How long does installation take in Crawley?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Crawley home states the expected time.
