Air source heat pump installation for Exmouth homes
In Exmouth, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Terraced streets in Exmouth often mean a compact unit position at the rear, so siting and sound levels are checked carefully. For older properties in Exmouth, 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.
- Households with room for a hot water cylinder
- Homes replacing a gas, oil, LPG or electric heating system
- 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
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
Homeowners across Devon can arrange a survey in Exmouth for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
Homes in Exmouth 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.

Air source heat pump installation in Exmouth: questions
Can you service a heat pump in Exmouth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Exmouth, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on an Exmouth 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 Exmouth home.
How soon can you survey a home in Exmouth?
Survey dates depend on how busy installers are in Devon. We offer the next available dates when you enquire and confirm them in writing.
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.
