Before you book: air source heat pump installation in Barnstaple
A heat pump suits most Barnstaple homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For older properties in Barnstaple, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Terraced streets in Barnstaple 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.
- Households with room for a hot water cylinder
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
What's included
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
Installers working in Barnstaple plan the order of work so heating and hot water are off for as short a time as practical.
Grants and rules for heat pumps in England
Homes in Barnstaple 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 Barnstaple: questions
Do I need new radiators for a heat pump in Barnstaple?
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 Barnstaple home gives a room-by-room list.
Where would the outdoor unit go on a Barnstaple 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 Barnstaple home.
How long does a heat pump survey take in Barnstaple?
A home survey in Barnstaple usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
