Multi-split air conditioning in Sevenoaks
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. Twin and triple systems suit Sevenoaks homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit.
In a house in Sevenoaks with a usable loft, multi-split pipes can often run through it so the front stays clear. Sevenoaks is about 14 miles from Maidstone and falls within our Kent coverage. That includes the TN13 postcode district.

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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. A survey in Sevenoaks 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.
