Ducted air conditioning across Surrey
Ducted systems suit Woking loft conversions and new extensions where ceilings are being boarded anyway. For a renovation in Woking, the best time to plan ducted cooling is before the plasterers arrive. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Prices in Surrey
In South East England, our guide range for ducted air conditioning is £6,645–£18,245 per system, including VAT. South East England is one of the dearer parts of the UK for trades, which shows in the range. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £9,095–£13,345 here.

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
On a survey in Surrey 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. A survey in Surrey 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.
