What to know about heat loss surveys in Bradford-on-Avon
Every property in Bradford-on-Avon is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Design outdoor temperatures for Bradford-on-Avon and the wider Wiltshire come from local cold-weather data, not a national average. The survey in Bradford-on-Avon includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- 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
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Homeowners in Bradford-on-Avon 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
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 Bradford-on-Avon 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.

Heat loss surveys in Bradford-on-Avon: questions
Do you cover Trowbridge as well as Bradford-on-Avon?
Yes. We arrange surveys and installation in Trowbridge, which is about 3 miles south-east of Bradford-on-Avon, and across Wiltshire.
Where would the outdoor unit go on a Bradford-on-Avon 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 Bradford-on-Avon home.
How long does installation take in Bradford-on-Avon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Bradford-on-Avon home states the expected time.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
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.
