Grants and rules for heat pumps in Wales
Homes in Gorseinon can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Winter daylight and heating in Gorseinon

Heat pumps in Gorseinon: questions
What size heat pump does a Gorseinon 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 Gorseinon home.
How long does a heat pump survey take in Gorseinon?
A home survey in Gorseinon 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.
Do I need new radiators for a heat pump in Gorseinon?
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 Gorseinon home gives a room-by-room list.
Can you service a heat pump in Gorseinon that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Gorseinon, whoever fitted them. Tell us the make and model when you book.
