Wall-mounted air conditioning in Windsor
A single wall-mounted unit is often all a bedroom or sunny living room in Windsor needs. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Where a home in Windsor faces the street, the outdoor unit usually goes at the rear, out of sight. Windsor sits around 16 miles from Reading, inside our Berkshire area. Homes in SL4 are all within our coverage.
Prices in Windsor
Our South East England guide price for wall-mounted air conditioning is £1,395–£3,595 per room, VAT included. South East England is one of the dearer parts of the UK for trades, which shows in the range. 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. 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.

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
On a survey in Windsor 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. 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.
