Ducted air conditioning in Gravesend
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In an older house in Gravesend, the loft and any existing bulkheads decide whether a ducted layout will work.
For a renovation in Gravesend, the best time to plan ducted cooling is before the plasterers arrive. Gravesend sits around 14 miles from Maidstone, inside our Kent area. Coverage includes DA12.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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. On a survey in Gravesend 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.
