Ducted air conditioning across Wiltshire
Ducted systems suit Swindon loft conversions and new extensions where ceilings are being boarded anyway. For a renovation in Swindon, the best time to plan ducted cooling is before the plasterers arrive. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
Prices in Wiltshire
Budget around £5,450–£14,950 per system including VAT for ducted air conditioning in and around Wiltshire. It sits near the middle of UK prices. What moves a quote in Wiltshire up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our South West England figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £7,450–£10,950.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
A survey in Wiltshire 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. On a survey in Wiltshire the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
