Ducted air conditioning in Leatherhead
For a renovation in Leatherhead, the best time to plan ducted cooling is before the plasterers arrive. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
In an older house in Leatherhead, the loft and any existing bulkheads decide whether a ducted layout will work. We cover Leatherhead as part of Surrey, roughly 10 miles from Woking. That includes the KT22 postcode district.
Prices in Leatherhead
Ducted air conditioning in Leatherhead typically comes in at £6,645–£18,245 per system including VAT, based on South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our South East England figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £9,095–£13,345.

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
A survey in Leatherhead 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. 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.
