Air conditioning for extensions and kitchen-diners in Shaftesbury
For a kitchen-diner in Shaftesbury, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
An extension in Shaftesbury with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Dorset coverage takes in Shaftesbury, about 24 miles from Bournemouth. Coverage includes SP7.

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.
