Air conditioning for extensions and kitchen-diners in Gelligaer
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. An extension in Gelligaer with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Gelligaer, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Gelligaer lies roughly 18 miles from Bridgend, and we cover it as part of Mid Glamorgan. Postcode districts we cover here include CF82.

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 Gelligaer 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.
