Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Twickenham quote.
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 pump guide prices in Twickenham
These are guide prices for Greater London, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

Designing for Twickenham's winters
Twickenham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
Heat pumps in Twickenham: questions
Where would the outdoor unit go on a Twickenham 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 Twickenham home.
What size heat pump does a Twickenham 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 Twickenham home.
How long does installation take in Twickenham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Twickenham home states the expected time.
Can you service a heat pump in Twickenham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Twickenham, whoever fitted them. Tell us the make and model when you book.
