Grants and rules for heat pumps in England
Homes in Hatfield 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 Hatfield
On the shortest day Hatfield gets about 7 hours 47 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.
Heat pumps in Hatfield: questions
Do you cover Welwyn Garden City as well as Hatfield?
Yes. We arrange surveys and installation in Welwyn Garden City, which is about 3 miles north of Hatfield, and across Hertfordshire.
Can you service a heat pump in Hatfield that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hatfield, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Hatfield 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 Hatfield home.
How long does installation take in Hatfield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hatfield home states the expected time.
