Air conditioning for extensions and kitchen-diners across Mid Glamorgan
For a kitchen-diner in Bridgend, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. An extension in Bridgend with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.

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.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. Surveys in Mid Glamorgan cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
