We cover East Grinstead and nearby Crawley, Haywards Heath and the rest of West Sussex. A heat pump is a whole-system change, so the survey looks at radiators, pipework, the hot water cylinder and the best spot for the outdoor unit.

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 East Grinstead 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.

How long is the heating season in East Grinstead?
On the shortest day East Grinstead gets about 7 hours 53 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 East Grinstead: questions
Do you cover Crawley as well as East Grinstead?
Yes. We arrange surveys and installation in Crawley, which is about 8 miles west of East Grinstead, and across West Sussex.
How long does a heat pump survey take in East Grinstead?
A home survey in East Grinstead 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.
Where would the outdoor unit go on an East Grinstead 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 East Grinstead home.
What size heat pump does an East Grinstead home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your East Grinstead home.
