Air conditioning for extensions and kitchen-diners in Cowes
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. An extension in Cowes with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Cowes, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Cowes is about 4 miles from Newport, Isle of Wight and falls within our Isle of Wight coverage. That includes the PO31 postcode district.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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.
