Air conditioning for extensions and kitchen-diners in Willenhall
Away from the coast, West Midlands summers can turn hot quickly, and bedrooms under the roof are the first to suffer. An extension in Willenhall with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Willenhall, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Willenhall lies roughly 10 miles from Birmingham, and we cover it as part of the West Midlands. Postcode districts we cover here include WV13.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
