Multi-split air conditioning in Sittingbourne
Twin and triple systems suit Sittingbourne homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Multi-split is a good fit for Sittingbourne flats and maisonettes where only a balcony or one rear wall is available. We cover Sittingbourne as part of Kent, roughly 11 miles from Maidstone. We cover ME10 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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
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 Sittingbourne 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.
