Ducted air conditioning in Horley
Ducted systems suit Horley loft conversions and new extensions where ceilings are being boarded anyway. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
For a renovation in Horley, the best time to plan ducted cooling is before the plasterers arrive. We cover Horley as part of Surrey, roughly 20 miles from Woking. That includes the RH6 postcode district.
Prices in Horley
Our South East England guide price for ducted air conditioning is £6,645–£18,245 per system, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. 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.
The survey
Surveys in Horley cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Horley 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.
