Before you book: heat loss surveys in Barnstaple
Most homes can run on a heat pump if the system is designed properly, and Barnstaple is no different. The key is matching the heat pump and radiators to the home's heat loss.
Design outdoor temperatures for Barnstaple and the wider Devon come from local cold-weather data, not a national average. For Barnstaple homes with extensions or loft conversions, each part of the house is assessed on its own construction.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
What's included
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
Houses in Barnstaple built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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.

Designing for Barnstaple's winters
On the shortest day Barnstaple gets about 7 hours 54 minutes of daylight, and the winter sun reaches only around 15° 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.

Heat loss surveys in Barnstaple: questions
How long does installation take in Barnstaple?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Barnstaple home states the expected time.
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.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
