Air conditioning for extensions and kitchen-diners in King's Lynn
An extension in King's Lynn with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
For a kitchen-diner in King's Lynn, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover King's Lynn as part of Norfolk, roughly 39 miles from Norwich. Homes in PE30 are all within our coverage.

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%.
