Ducted air conditioning in Cowes
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 Cowes, the loft and any existing bulkheads decide whether a ducted layout will work.
Ducted systems suit Cowes loft conversions and new extensions where ceilings are being boarded anyway. Cowes is about 4 miles from Newport, Isle of Wight and falls within our Isle of Wight coverage. Postcode districts we cover here include PO31.
Prices in Cowes
In South East England, our guide range for ducted air conditioning is £6,645–£18,245 per system, including VAT. What moves a quote in Cowes up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. For reference, the Zoned option in Cowes (motorised dampers or two units for separate floors or room groups) usually comes to about £9,095–£13,345. These figures exclude travel to Cowes. Any travel, ferry or accommodation cost is quoted separately, in writing, before anything is booked.

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
In Cowes we often start with photos, room measurements and the make of any existing system, so the survey visit is focused and any travel cost can be quoted in writing first. Where travel is involved, we agree the survey arrangements and any travel cost up front. On the day, the engineer measures the rooms, checks the electrics and agrees the outdoor unit position with you.
