Planning low-carbon heating in Abergavenny.
An air source heat pump should be sized from evidence, not guesswork. Property heat loss, available outdoor space and the way each room is heated all matter when considering a home in Monmouthshire. Current Boiler Upgrade Scheme support is subject to the property, technology, MCS and scheme eligibility rules.
The Boiler Upgrade Scheme offers £7,500 towards an eligible air-to-water heat pump in England or Wales. Qualifying homes currently heated by oil or LPG, with no mains-gas connection, may receive an additional £1,500 (£9,000 in total) until March 2027. An MCS-certified installer must confirm eligibility and apply on your behalf; approval is not guaranteed.
Running costs and any savings depend on the property, system design, controls and energy tariff.

Coverage is organised around NP7 and neighbouring parts of Monmouthshire, including Monmouth, Usk, Blaenavon and Crickhowell. Contact the team with the property postcode and a short description of the job for a firm availability check.
Should an extension or altered layout be discussed during a Abergavenny assessment?
