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

Winter daylight and heating in Southall
On the shortest day Southall gets about 7 hours 49 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 Southall: questions
What size heat pump does a Southall 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 Southall home.
How long does installation take in Southall?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Southall home states the expected time.
Do you cover Hayes as well as Southall?
Yes. We arrange surveys and installation in Hayes, which is about 2 miles west of Southall, and across Greater London.
Can you service a heat pump in Southall that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Southall, whoever fitted them. Tell us the make and model when you book.
