Air conditioning for extensions and kitchen-diners in Cowbridge
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. An extension in Cowbridge with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Cowbridge, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Cowbridge as part of South Glamorgan, roughly 11 miles from Cardiff. Homes in CF71 are all within our coverage.
Prices in Cowbridge
Guide prices around Cowbridge run from £1,345 to £4,095 per space including VAT. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,895–£2,595 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Cowbridge can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
Surveys in Cowbridge cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in Cowbridge usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
