Energy Certificates

The Energy Performance of Buildings (Certificates and Inspections) (England and Wales) 2007, requires Display Energy Certificates (DEC) to be in place for all public buildings over 1,000m2 by 1 October 2008.

Under this legislation the occupier of the building must:

  • Display a valid DEC in a prominent place clearly visible to the public at all times. 

  • Have in their possession or control a valid Advisory Report.

  • DECs must be renewed each and every year.

  • Advisory Reports must be renewed every seven years.

  • DECs must be issued by a qualified and accredited assessor.

  • DECs must be lodged with the appropriate government register.

  • All the data utilised must have an accurate auditable trail.
