Garden room and home office air conditioning across County Antrim

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
Planning rules for outdoor units in Northern Ireland differ from Great Britain's, so we check your property with you and the council where needed.
