Air-to-air heat pumps in Llantwit Major
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. We size every heat pump in Llantwit Major for a cold winter day, then check the cooling side is right for summer.
Homes in Llantwit Major on electric, oil or LPG heating are the ones most likely to benefit from an air-to-air heat pump. We cover Llantwit Major as part of South Glamorgan, roughly 14 miles from Cardiff. We cover CF61 and the streets around them.
Prices in Llantwit Major

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
If your home in Llantwit Major is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
