Air conditioning for extensions and kitchen-diners across the Isle of Wight
An extension in Newport with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Newport, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Prices on the Isle of Wight
Guide prices around the Isle of Wight run from £1,745 to £5,445 per space including VAT. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our South East England figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £2,495–£3,495. Travel, ferry or accommodation costs are not in these figures; they are quoted as a fixed amount in writing before you book.

Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
On the Isle of Wight 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. Surveys on the Isle of Wight are arranged around travel. We confirm the date and any travel, ferry or accommodation cost in writing before you commit, then the survey covers rooms, pipe routes, electrics and noise as normal.
