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

Designing for Petworth's winters
Petworth sees roughly 7 hours 55 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 Petworth: questions
How long does a heat pump survey take in Petworth?
A home survey in Petworth usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do I need new radiators for a heat pump in Petworth?
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 Petworth home gives a room-by-room list.
How long does installation take in Petworth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Petworth home states the expected time.
Do you cover Midhurst as well as Petworth?
Yes. We arrange surveys and installation in Midhurst, which is about 6 miles west of Petworth, and across West Sussex.
