Heat pump grants for Lewes homes
A heat pump suits most Lewes homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installation dates in Lewes are fixed around any funding confirmation, so work does not start too early. Homeowners in Lewes get a clear written quote showing the full price and any funding that applies.
Heat pump funding depends on which UK nation you live in, so we confirm what applies to your home and handle the grant steps alongside your quote.
- Homes in England and Wales on oil or LPG, where a higher grant applies between set dates
- Homeowners in England and Wales replacing gas, oil, LPG or electric heating
- Anyone unsure which scheme applies and wanting it checked before committing
What's included
- MCS certificate and handover documents after installation
- Boiler Upgrade Scheme application made by the MCS-certified installer (England and Wales)
- Eligibility check for the scheme that covers your nation
- Written quote showing the full price and any grant deduction
- Installation scheduled around your grant confirmation or funding offer
For landlords with property in Lewes, we explain the funding position for each home before quoting.
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 Lewes 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.

How long is the heating season 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.
How installation works in Lewes
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Lewes home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump grants in Lewes: questions
Do you cover Peacehaven as well as Lewes?
Yes. We arrange surveys and installation in Peacehaven, which is about 6 miles south of Lewes, and across East Sussex.
How soon can you survey a home in Lewes?
Survey dates depend on how busy installers are in East Sussex. We offer the next available dates when you enquire and confirm them in writing.
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.
How much is the heat pump grant?
It depends on where you live. In England and Wales, the Boiler Upgrade Scheme pays £7,500 towards an air-to-water heat pump, or £9,000 when replacing oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers up to £7,500, plus a rural uplift and an optional loan. Northern Ireland has no dedicated grant at present.
Do I need an EPC for the Boiler Upgrade Scheme?
No longer. Since 28 April 2026, a valid EPC is not required for the Boiler Upgrade Scheme in England and Wales. The system must still meet the home's full heating and hot water needs, which the room-by-room heat loss calculation confirms. The other eligibility rules, such as owning the property, still apply.
