Multi-split air conditioning in Mitcham
Twin and triple systems suit Mitcham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
In a house in Mitcham with a usable loft, multi-split pipes can often run through it so the front stays clear. Mitcham sits around 7 miles from central London, inside our London area. We cover CR4 and the streets around them.

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
For most houses in Mitcham, 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
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. On a survey in Mitcham 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.
