Multi-split air conditioning across Wiltshire
Multi-split is a good fit for Swindon flats and maisonettes where only a balcony or one rear wall is available. In a house in Swindon with a usable loft, multi-split pipes can often run through it so the front stays clear. 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
Our South West England guide price for multi-split air conditioning is £2,450–£7,750 for 2–4 rooms, VAT included. It sits near the middle of UK prices. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the Triple option in Wiltshire (three rooms with mixed indoor styles and Wi-Fi control throughout) usually comes to about £3,350–£5,450.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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.
The survey
We book surveys in Wiltshire at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
