Ducted air conditioning in Swanley
For a renovation in Swanley, 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.
In an older house in Swanley, the loft and any existing bulkheads decide whether a ducted layout will work. Swanley lies roughly 17 miles from Maidstone, and we cover it as part of Kent. Homes in BR8 are all within our coverage.
Prices in Swanley
Budget around £6,645–£18,245 per system including VAT for ducted air conditioning in and around Swanley. That is above the UK middle, mainly because labour and access cost more in South East England. 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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

We book surveys in Swanley 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.
