Ducted air conditioning in Guildford
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Ducted systems suit Guildford loft conversions and new extensions where ceilings are being boarded anyway.
For a renovation in Guildford, the best time to plan ducted cooling is before the plasterers arrive. Guildford is about 6 miles from Woking and falls within our Surrey coverage. Postcode districts we cover here include GU1.
Prices in Guildford
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. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. Typical Zoned work (motorised dampers or two units for separate floors or room groups) lands around £9,095–£13,345 in this area.
Single zone
One ducted unit serving two or three rooms from a loft or void.

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
For most houses in Guildford, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
Surveys in Guildford cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Guildford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
