Air conditioning for extensions and kitchen-diners in Egham
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. An extension in Egham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Egham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Egham lies roughly 8 miles from Woking, and we cover it as part of Surrey. We cover TW20 and the streets around them.
Prices in Egham
For Egham, expect roughly £1,745 to £5,445 per space, VAT included, adjusted for typical South East England rates. 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 Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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 Egham, 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.
