An EPC informs you about the energy performance of a property. It is a legal requirement for the landlord to prepare and provide an EPC prior to the property to be marketed.
Energy ratings on an EPC vary from A (most energy sufficient) to G (most energy inefficient). The EPC ratings should be better for newer properties than older buildings. You may want to negotiate your proposed rental level with your landlord if the property has a poor rating.
You should seek advice from a professional EPC consultant on how to lower your carbon footprint and reduce your utility bills.
