Grants and rules for heat pumps in England
Homes in Letchworth Garden City 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 grants in Letchworth Garden City: questions
Do I need new radiators for a heat pump in Letchworth Garden City?
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 Letchworth Garden City home gives a room-by-room list.
What size heat pump does a Letchworth Garden City 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 Letchworth Garden City home.
Do you cover Hitchin as well as Letchworth Garden City?
Yes. We arrange surveys and installation in Hitchin, which is about 3 miles south-west of Letchworth Garden City, and across Hertfordshire.
How much is the heat pump grant?
It depends on where you live. In England and Wales, the Boiler Upgrade Scheme pays £7,500 towards an air-to-water heat pump, or £9,000 when replacing oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers up to £7,500, plus a rural uplift and an optional loan. Northern Ireland has no dedicated grant at present.
Who applies for the Boiler Upgrade Scheme?
In England and Wales, the MCS-certified installer applies to Ofgem for the Boiler Upgrade Scheme on your behalf, and the grant is deducted from your quote. Ofgem then contacts you as the property owner to confirm the details. Your quote names the MCS-certified installer for your job, so you know who is making the application.
