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 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.

A survey in Merthyr Tydfil usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
