Grants and rules for heat pumps in Wales
Homes in Caerphilly 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.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Winter daylight and heating in Caerphilly
On the shortest day Caerphilly 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 Caerphilly: questions
How soon can you survey a home in Caerphilly?
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.
What size heat pump does a Caerphilly 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 Caerphilly home.
Where would the outdoor unit go on a Caerphilly 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 Caerphilly home.
How long does installation take in Caerphilly?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Caerphilly home states the expected time.
