Ducted air conditioning across East Sussex
In an older house in Brighton, the loft and any existing bulkheads decide whether a ducted layout will work. Ducted systems suit Brighton loft conversions and new extensions where ceilings are being boarded anyway. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.

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.
