Multi-split air conditioning in Whitstable
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In a house in Whitstable with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Whitstable flats and maisonettes where only a balcony or one rear wall is available. We cover Whitstable as part of Kent, roughly 23 miles from Maidstone. Postcode districts we cover here include CT5.

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 Whitstable, 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
We book surveys in Whitstable at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Whitstable 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.
