Air conditioning for extensions and kitchen-diners in Hexham
Cooler North East summers mean cooling is mostly needed in lofts, conservatories and rooms with large windows. An extension in Hexham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Hexham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Hexham lies roughly 26 miles from Blyth, and we cover it as part of Northumberland. Homes in NE46 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
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.
