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.
