Air conditioning for extensions and kitchen-diners in Leatherhead
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. For a kitchen-diner in Leatherhead, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Leatherhead with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Leatherhead as part of Surrey, roughly 10 miles from Woking. Coverage includes KT22.
Prices in Leatherhead
Budget around £1,745–£5,445 per space including VAT for air conditioning for extensions and kitchen-diners in and around Leatherhead. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Leatherhead up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical Large single work (one 5–7 kW unit for a large glazed space) lands around £2,495–£3,495 in this area.

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
For most houses in Leatherhead, 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
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. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
