What to know about air source heat pump installation in Sidmouth
Homes around Sidmouth range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Terraced streets in Sidmouth often mean a compact unit position at the rear, so siting and sound levels are checked carefully. Homeowners across Devon can arrange a survey in Sidmouth 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.
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- MCS registration and certificate, plus network operator notification
- Boiler Upgrade Scheme application in England and Wales where eligible
For older properties in Sidmouth, 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
Homes in Sidmouth 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.
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 Sidmouth and what they mean
Sidmouth sees roughly 7 hours 58 minutes of daylight in late December against 16 hours 29 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 Sidmouth: questions
Do you cover Honiton as well as Sidmouth?
Yes. We arrange surveys and installation in Honiton, which is about 8 miles north of Sidmouth, and across Devon.
How long does installation take in Sidmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sidmouth home states the expected time.
Do I need new radiators for a heat pump in Sidmouth?
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 Sidmouth home gives a room-by-room list.
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.
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.
