As a general rule, the following minimum surveillance auditing requirements are in place:

  • At least 2% of all EPCs lodged through the Scheme are audited;
  • Energy Assessors are randomly audited on at least 1% of their lodged reports, with a minimum of 1 random audit per year;
  • Each new Energy Assessor will have their first lodged EPC audited;
  • Audits which trigger risk-based selection criteria.

There are other circumstances which would require surveillance checks:

  • Customer complaints.


In addition to these requirement, we also undertake auditing on those certificates that have been re-lodged following a surveillance auditing failure.
