SUMMARY The government wants all non-domestic rented buildings to meet an EPC B by 2030 (currently the requirement is EPC E). It is consulting on how to implement this and to improve the compliance and enforcement process for EPCs. The change will affect one million properties. WHAT IS AN EPC? An EPC shows the energy efficiency levels of a property, so for example a prospective tenant can find out and compare the relative running costs of renting a property. The certificate will give each building a Standard Assessment Procedure (known as a SAP) and then there is a rating, which is graded from A to G (A is very efficient and G is very inefficient). The certificate contains information including, an estimation of the energy the property potentially uses, fuel costs i.e. an indication of how much it will cost to heat a property, details of savings that could be made if energy efficiency improvements are made, and CO2 emissions.
