Grants and rules for heat pumps in England
Homes in Lewes 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.
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.
Heat pump guide prices in Lewes
The ranges below are typical installed prices for homes in East Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Lewes can need quite different radiators and pipework.

Winter daylight and heating in Lewes
Lewes sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 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 Lewes: questions
Can you service a heat pump in Lewes that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lewes, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Lewes?
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 Lewes home gives a room-by-room list.
Where would the outdoor unit go on a Lewes 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 Lewes home.
What size heat pump does a Lewes 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 Lewes home.
