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.
