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

Short winter days in Monmouth and what they mean
On the shortest day Monmouth gets about 7 hours 46 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 Monmouth: questions
How long does installation take in Monmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Monmouth home states the expected time.
Where would the outdoor unit go on a Monmouth 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 Monmouth home.
What size heat pump does a Monmouth 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 Monmouth home.
Do you cover Chepstow as well as Monmouth?
Yes. We arrange surveys and installation in Chepstow, which is about 12 miles south of Monmouth, and across Gwent.
