Quick Answer

EPC ratings run from A (most efficient) to G (least efficient). The rating estimates annual energy costs and CO2 emissions. Most Scottish homes rate D-E. Ratings below E may affect mortgages and rental legality. Improvements to reach C typically cost £5,000-15,000 but can add 5-10% to property value.
