Wall-mounted air conditioning in Sutton
A single wall-mounted unit is often all a bedroom or sunny living room in Sutton needs. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
Where a home in Sutton faces the street, the outdoor unit usually goes at the rear, out of sight. Sutton lies roughly 11 miles from central London, and we cover it as part of London. Coverage includes RH5, SM1 and SM2.
Prices in Sutton
In London, our guide range for wall-mounted air conditioning is £1,495–£3,895 per room, including VAT. London is one of the dearer parts of the UK for trades, which shows in the range. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our London figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £2,045–£2,845.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
A survey in Sutton usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. 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.
