Grants and rules for heat pumps in England
Homes in Bath 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 pump guide prices in Bath
The ranges below are typical installed prices for homes in Somerset, including VAT. A survey sets the exact figure, because two similar-looking houses in Bath can need quite different radiators and pipework.

Winter daylight and heating in Bath
On the shortest day Bath 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 Bath: questions
Do I need new radiators for a heat pump in Bath?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Bath home gives a room-by-room list.
What size heat pump does a Bath 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 Bath home.
Do you cover Keynsham as well as Bath?
Yes. We arrange surveys and installation in Keynsham, which is about 6 miles north-west of Bath, and across Somerset.
How soon can you survey a home in Bath?
Survey dates depend on how busy installers are in Somerset. We offer the next available dates when you enquire and confirm them in writing.
