Wall-mounted air conditioning in Esher
A single wall-mounted unit is often all a bedroom or sunny living room in Esher needs. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
Where a home in Esher faces the street, the outdoor unit usually goes at the rear, out of sight. We cover Esher as part of Surrey, roughly 9 miles from Woking. That includes the KT10 postcode district.
Prices in Esher
In South East England, our guide range for wall-mounted air conditioning is £1,395–£3,595 per room, 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. On our South East England figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £1,895–£2,595.
Essential
Reliable 2.5–3.5 kW unit for a bedroom or study, standard pipe run, basic remote.
Popular
Quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room.
Premium

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
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. 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.
