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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Milford Haven can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
