What's it like?

Commercial energy assessors test how energy-efficient commercial buildings are – like shopping centres, cinemas and offices.

They create Non-Domestic Energy Performance Certificates that can recommend how businesses can be more energy efficient. This can make a big difference to the environment around us and make sure the public are safe while out and about. 

As a commercial energy assessor, you could:

  • inspect commercial buildings to collect information on their age, number of floors, building type, and heating and hot water systems
  • note the number and sizes of rooms and windows
  • record the information into a computer software programme
  • produce Non-Domestic Energy Performance Certificates (NDEPCs)
  • explain the information collected to clients and businesses owners
  • give practical advice and recommendations that can save businesses money while improving energy efficiency
  • as you get more experience as a commercial energy assessor you’ll generally assess larger buildings. This could mean improving your salary too.

You could also consult on energy efficiency to investors and people looking to build commercial properties.
