Before you book: heat loss surveys in Truro
In Truro, 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.
Houses in Truro built in different eras can need very different heat pump sizes, which is why each is calculated room by room. A surveyor visits your Truro home to measure each room, window and wall before any heat pump is sized.
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
- Homes with an existing heat pump that seems undersized or expensive to run
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Room-by-room heat loss calculation using the MCS method
Design outdoor temperatures for Truro and the wider Cornwall come from local cold-weather data, not a national average.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Truro quote.
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.
Guide prices for heat loss surveys in Truro
The ranges below are typical installed prices for homes in Cornwall, including VAT. A survey sets the exact figure, because two similar-looking houses in Truro 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–£410 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Truro's winters
On the shortest day Truro gets about 8 hours 02 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 Truro: questions
Do you cover Falmouth as well as Truro?
Yes. We arrange surveys and installation in Falmouth, which is about 8 miles south of Truro, and across Cornwall.
Where would the outdoor unit go on a Truro 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 Truro home.
What size heat pump does a Truro home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Truro home.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
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.
