Grants and rules for heat pumps in Wales
Homes in Llantrisant 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.

Designing for Llantrisant's winters
On the shortest day Llantrisant gets about 7 hours 49 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 Llantrisant: questions
Do I need new radiators for a heat pump in Llantrisant?
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 Llantrisant home gives a room-by-room list.
Do you cover Pontypridd as well as Llantrisant?
Yes. We arrange surveys and installation in Pontypridd, which is about 4 miles north of Llantrisant, and across Mid Glamorgan.
How long does a heat pump survey take in Llantrisant?
A home survey in Llantrisant 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.
How soon can you survey a home in Llantrisant?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
