Air conditioning for extensions and kitchen-diners in Esher
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In Esher, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Esher, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Esher is about 9 miles from Woking and falls within our Surrey coverage. Coverage includes KT10.
Prices in Esher
For Esher, 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. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. 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%.

Planning and permissions
For most houses in Esher, 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 Esher cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Esher 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.
