Air conditioning for extensions and kitchen-diners in Salisbury
Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks. An extension in Salisbury with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Salisbury, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Salisbury as part of Wiltshire, roughly 34 miles from Swindon. We cover SP1 and the streets around them.

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
For most houses in Salisbury, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
A survey in Salisbury 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. Surveys in Salisbury cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
