Grants and rules for heat pumps in England
Homes in Pinner 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.
Heat pump guide prices in Pinner
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.

How long is the heating season in Pinner?
Pinner sees roughly 7 hours 49 minutes of daylight in late December against 16 hours 39 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 Pinner: questions
Do you cover Harrow as well as Pinner?
Yes. We arrange surveys and installation in Harrow, which is about 2 miles south-east of Pinner, and across Greater London.
Do I need new radiators for a heat pump in Pinner?
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 Pinner home gives a room-by-room list.
What size heat pump does a Pinner 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 Pinner home.
Where would the outdoor unit go on a Pinner 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 Pinner home.
