Air conditioning for extensions and kitchen-diners in Ventnor
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. An extension in Ventnor with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Ventnor, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Ventnor is about 8 miles from Newport, Isle of Wight and falls within our Isle of Wight coverage. We cover PO38 and the streets around them.

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
For most houses in Ventnor, 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
Surveys in Ventnor 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. 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.
