Ducted air conditioning in Chichester
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. In an older house in Chichester, the loft and any existing bulkheads decide whether a ducted layout will work.
For a renovation in Chichester, the best time to plan ducted cooling is before the plasterers arrive. We cover Chichester as part of West Sussex, roughly 32 miles from Crawley. Coverage includes PO19.
Prices in Chichester
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. What moves a quote in Chichester up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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.

Guide prices show VAT at 20%.

Planning and permissions
For most houses in Chichester, 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
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. On a survey in Chichester 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.
