Grants and rules for heat pumps in England
Homes in Trowbridge 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.

Short winter days in Trowbridge and what they mean
On the shortest day Trowbridge gets about 7 hours 51 minutes of daylight, and the winter sun reaches only around 15° 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 pumps in Trowbridge: questions
Where would the outdoor unit go on a Trowbridge 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 Trowbridge home.
How soon can you survey a home in Trowbridge?
Survey dates depend on how busy installers are in Wiltshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Bradford-on-Avon as well as Trowbridge?
Yes. We arrange surveys and installation in Bradford-on-Avon, which is about 3 miles north-west of Trowbridge, and across Wiltshire.
What size heat pump does a Trowbridge 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 Trowbridge home.
