The energy consumption of an A1 BER house is about 5% of a G rated home. Preliminary results from a recent ESRI paper suggest that a one step improvement in the 15 point BER scale is associated with a 1.3% higher price and a one step improvement in the BER scale is also associated with a 0.5% increase in residential higher rent. An A rated house commands a premium of nearly 10% as compared to a D rated house and a property rated F or G trades at a 10% discount.
