Energy Performance Certificates

An Energy Performance Certificate (EPC) grades the energy efficiency of a property (with A representing the most efficient grade). Hollis Hockley recommend appointing accredited assessors.


When must an Energy Performance Certificate be commissioned?

Since 2008 it has been a legal requirement to have an EPC if:

  • A property is marketed to let or for sale
  • A building under construction is completed
  • There are changes to the number of parts used for separate occupation and these changes involve providing or extending fixed heating, air conditioning, or mechanical ventilation systems
