Grants and rules for heat pumps in England

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 Wandsworth 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.

On the shortest day Wandsworth gets about 7 hours 50 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 Wandsworth: questions

Do I need new radiators for a heat pump in Wandsworth?

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 Wandsworth home gives a room-by-room list.

How long does installation take in Wandsworth?

Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wandsworth home states the expected time.

How long does a heat pump survey take in Wandsworth?

A home survey in Wandsworth 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.

Can you service a heat pump in Wandsworth that someone else installed?

Yes. We arrange servicing and repairs for most air source heat pumps in Wandsworth, whoever fitted them. Tell us the make and model when you book.
