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.
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 pumps in Westbury-on-Trym: questions
How long does a heat pump survey take in Westbury-on-Trym?
A home survey in Westbury-on-Trym 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 Bishopston as well as Westbury-on-Trym?
Yes. We arrange surveys and installation in Bishopston, which is about a mile south-east of Westbury-on-Trym, and across Bristol.
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.
Where would the outdoor unit go on a Westbury-on-Trym 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 Westbury-on-Trym home.
