Before you book: heat loss surveys in Honiton
A heat pump suits most Honiton homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Design outdoor temperatures for Honiton and the wider Devon come from local cold-weather data, not a national average. Houses in Honiton built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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.
- Self-builders and architects who need emitter and system sizes early
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
What's included
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
Homeowners in Honiton thinking about insulation work can use the survey to see how it would change their heat pump size.
Grants and rules for heat pumps in England
Homes in Honiton 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.
Heat loss survey prices in Honiton
The ranges below are typical installed prices for homes in Devon, including VAT. A survey sets the exact figure, because two similar-looking houses in Honiton can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Honiton?
On the shortest day Honiton gets about 7 hours 57 minutes of daylight, and the winter sun reaches only around 16° 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 Honiton: questions
Do I need new radiators for a heat pump in Honiton?
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 Honiton home gives a room-by-room list.
Do you cover Sidmouth as well as Honiton?
Yes. We arrange surveys and installation in Sidmouth, which is about 8 miles south of Honiton, and across Devon.
How long does installation take in Honiton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Honiton home states the expected time.
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.
