Air conditioning for extensions and kitchen-diners in Cumbernauld
An extension in Cumbernauld with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Mild Scottish summers mean cooling matters most in conservatories, lofts and rooms with large windows.
In Cumbernauld, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our Lanarkshire coverage takes in Cumbernauld, about 13 miles from Hamilton. Coverage includes G67.

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
Outdoor units on Scottish homes can often be installed without a planning application, but the conditions differ from England's, so we confirm the rules for your property at survey.
