Air conditioning for extensions and kitchen-diners in Chester-le-Street
Cold, windy North East winters favour a well-sized heat pump with an outdoor unit sheltered from the prevailing wind. An extension in Chester-le-Street with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Chester-le-Street, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Our County Durham coverage takes in Chester-le-Street, about 6 miles from Durham. Homes in DH3 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%.
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.
