Air conditioning for extensions and kitchen-diners in Woking
In Woking, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
For a kitchen-diner in Woking, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. As well as Woking itself, our Surrey coverage takes in Guildford, Esher and the towns around them. We cover GU22 and the streets around them.
Prices in Woking
Guide prices around Woking run from £1,745 to £5,445 per space including VAT. 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. For reference, the Large single option in Woking (one 5–7 kW unit for a large glazed space) usually comes to about £2,495–£3,495.
Single unit
One 3.5–5 kW unit for a medium extension.

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
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. Surveys in Woking cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
