Air conditioning for extensions and kitchen-diners across Lanarkshire
An extension in Hamilton with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. In Hamilton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In central and southern Scotland, heat pump heating is usually the main reason to install, especially in homes on electric heating.

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
Scotland has its own permitted development rules for heat pumps and outdoor units, with stricter treatment of listed buildings and conservation areas. We check the current position for your property with you and, if needed, with the council.
