Displaying of energy performance certificates

Since 25 February 2014, there has been a requirement for some commercial buildings that are visited by the public to display an Energy Performance Certificate (EPC). For more information on EPCs see our page on Energy Performance Certificates.

Which buildings are required to display an EPC?

You must display an EPC if: 

  • the total useful floor area is over 500m2 
  • the building is frequently visited by the public 
  • an EPC has already been produced for the building’s sale, rental or construction 

What if I haven’t got an EPC for the building?

If a building does not have a valid EPC, there is no need to have an EPC prepared.

How should the EPC be displayed? 

The EPC must be displayed in colour and at least A4 in size. It needs to be located in a prominent place that is clearly visible to members of the public who visit the building. 

Whose responsibility is it to display the EPC? 

It is the duty of the building occupier to display an EPC. 

How do I get an energy performance certificate? 

For more information on how to obtain an EPC, see our page on Energy Performance Certificates.

Are there any penalties for non-display of an EPC? 

Yes, the penalty is £500 for failing to display an EPC. For more information about penalties see our Enforcement policy page
