Ducted air conditioning in Eastbourne
In an older house in Eastbourne, the loft and any existing bulkheads decide whether a ducted layout will work. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Ducted systems suit Eastbourne loft conversions and new extensions where ceilings are being boarded anyway. Eastbourne sits around 19 miles from Brighton, inside our East Sussex area. Postcode districts we cover here include BN21.
Prices in Eastbourne
Our South East England guide price for ducted air conditioning is £6,645–£18,245 per system, VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. On our South East England figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £9,095–£13,345.

One ducted unit serving two or three rooms from a loft or void.

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
Surveys in Eastbourne cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.

Every job in Eastbourne includes:
- Free survey with ceiling-void and loft inspection
