Garden room and home office air conditioning in Mitcham
Garden offices used every day in Mitcham need cooling in summer and efficient heat in winter. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
For a garden room in Mitcham, the outdoor unit usually sits on a small stand behind the building. Mitcham sits around 7 miles from central London, inside our London area. Homes in CR4 are all within our coverage.

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 Mitcham 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.
