Air source heat pump installation for Alton homes
A heat pump suits most Alton 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 Alton plan the order of work so heating and hot water are off for as short a time as practical. For older properties in Alton, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- MCS registration and certificate, plus network operator notification
- Removal of the old boiler or heaters
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- Boiler Upgrade Scheme application in England and Wales where eligible
Terraced streets in Alton often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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 Alton quote.
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.

Short winter days in Alton and what they mean
Alton sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 34 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.

Air source heat pump installation in Alton: questions
Do I need new radiators for a heat pump in Alton?
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 Alton home gives a room-by-room list.
How long does installation take in Alton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Alton home states the expected time.
Do you cover Bordon as well as Alton?
Yes. We arrange surveys and installation in Bordon, which is about 5 miles south-east of Alton, and across Hampshire.
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.
