Before you book: heat loss surveys in Westbury-on-Trym
A heat pump suits most Westbury-on-Trym homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For Westbury-on-Trym homes with extensions or loft conversions, each part of the house is assessed on its own construction. A surveyor visits your Westbury-on-Trym 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.
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
What's included
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
The survey in Westbury-on-Trym includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Westbury-on-Trym 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 surveys in Westbury-on-Trym: questions
Can you service a heat pump in Westbury-on-Trym that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Westbury-on-Trym, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Westbury-on-Trym?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Westbury-on-Trym home states the expected time.
What size heat pump does a Westbury-on-Trym 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 Westbury-on-Trym 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.
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.
