Air source heat pump installation for Sandown homes
A heat pump suits most Sandown homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Many homes in Sandown 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 the Isle of Wight can arrange a survey in Sandown 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 and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
What's included
- System design, unit sizing and a written quote
- Outdoor unit, hot water cylinder and weather compensation controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
For older properties in Sandown, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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 Sandown 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 Sandown?
On the shortest day Sandown gets about 7 hours 58 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.

- Tell us about your home: postcode, property type and current heating.
- We book a survey in Sandown; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air source heat pump installation in Sandown: questions
Do I need new radiators for a heat pump in Sandown?
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 Sandown home gives a room-by-room list.
How long does installation take in Sandown?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sandown home states the expected time.
Do you cover Shanklin as well as Sandown?
Yes. We arrange surveys and installation in Shanklin, which is about 2 miles south-west of Sandown, and across the Isle of Wight.
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.
