Before you book: air source heat pump installation in Heathfield
Most homes can run on a heat pump if the system is designed properly, and Heathfield is no different. The key is matching the heat pump and radiators to the home's heat loss.
Many homes in Heathfield have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. Homeowners across East Sussex can arrange a survey in Heathfield for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners who want one contract covering design, fitting and paperwork
- Households with room for a hot water cylinder
- Houses with reasonable insulation, or a plan to improve it
What's included
- Removal of the old boiler or heaters
- MCS registration and certificate, plus network operator notification
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
In Heathfield, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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 Heathfield 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.

Designing for Heathfield's winters
On the shortest day Heathfield gets about 7 hours 55 minutes of daylight, and the winter sun reaches only around 16° 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.

Air source heat pump installation in Heathfield: questions
How soon can you survey a home in Heathfield?
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.
How long does installation take in Heathfield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Heathfield home states the expected time.
Can you service a heat pump in Heathfield that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Heathfield, whoever fitted them. Tell us the make and model when you book.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
