Heat loss survey for Taunton homes
Homes around Taunton range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Houses in Taunton built in different eras can need very different heat pump sizes, which is why each is calculated room by room. Homeowners in Taunton thinking about insulation work can use the survey to see how it would change their heat pump size.
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.
- Anyone getting a heat pump quote, as the first step
- Homes with an existing heat pump that seems undersized or expensive to run
- Self-builders and architects who need emitter and system sizes early
What's included
- Recommended heat pump size and design flow temperature
- Written results in your quote, or a stand-alone report if you order one
- Radiator schedule with any upgrades needed for each room
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Taunton and the wider Somerset come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
Homes in Taunton 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
Heat loss survey costs around Taunton
These are guide prices for Somerset, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| 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.
Short winter days in Taunton and what they mean
Taunton sees roughly 7 hours 54 minutes of daylight in late December against 16 hours 33 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.

Heat loss surveys in Taunton: questions
Do I need new radiators for a heat pump in Taunton?
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 Taunton home gives a room-by-room list.
How long does a heat pump survey take in Taunton?
A home survey in Taunton 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.
Do you cover Bridgwater as well as Taunton?
Yes. We arrange surveys and installation in Bridgwater, which is about 9 miles north-east of Taunton, and across Somerset.
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.
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.
