Air source heat pump installation in Crowborough: what to expect
A heat pump suits most Crowborough homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers working in Crowborough plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Crowborough often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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 and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
What's included
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- Commissioning, handover and a walk-through of the controls
- Outdoor unit, hot water cylinder and weather compensation controls
- Boiler Upgrade Scheme application in England and Wales where eligible
In Crowborough, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Crowborough 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.

Short winter days in Crowborough and what they mean
On the shortest day Crowborough gets about 7 hours 54 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.

Air source heat pump installation in Crowborough: questions
Where would the outdoor unit go on a Crowborough 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 Crowborough home.
How soon can you survey a home in Crowborough?
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 Crowborough?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Crowborough home states the expected time.
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.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
