Ducted air conditioning in Sevenoaks
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. For a renovation in Sevenoaks, the best time to plan ducted cooling is before the plasterers arrive.
In an older house in Sevenoaks, the loft and any existing bulkheads decide whether a ducted layout will work. Sevenoaks is about 14 miles from Maidstone and falls within our Kent coverage. Homes in TN13 are all within our coverage.
Prices in Sevenoaks
Our South East England guide price for ducted air conditioning is £6,645–£18,245 per system, VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Zoned option in Sevenoaks (motorised dampers or two units for separate floors or room groups) usually comes to about £9,095–£13,345.

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
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. A survey in Sevenoaks 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.
