From 1 April 2018 any building that is rented on a new tenancy must have an energy rating of at least an E.  From 2020, all buildings must have an energy rating of at least an E.  There are some exemptions to this, so please speak to Kirsty for further advice and assistance.  This new legislation does put a burden on Landlords to ensure that their properties meet the energy standards.  How this effects the availability of rental properties we will have to wait to see.
