Since 21st May 2010 every property placed on to the market for sale of for let requires an Energy Performance Certificate.
What is the purpose of an Energy Performance Certificate?
Energy Performance Certificates (EPC) were introduced to help improve the energy efficiency of buildings.
From October 2008 EPCs have been required whenever a building is built, sold or rented out. The certificate provides 'A' to 'G' ratings for the building, with 'A' being the most energy efficient and 'G' being the least, with the average up to now being 'D'.
Accredited energy assessors produce EPCs alongside an associated report which suggests improvements to make a building more energy efficient.
