Smart Rules for Domestic Existing Dwellings

Information about Smart Auditing

A smart audit is a ‘risk based’ audit based on pre-defined set of criteria as shown in the table below.

  • Smart audits are designed to find potentially defective Energy Certificates.
  • Smart audit selection will focus on the data items, and associated evidence, relevant to the smart rule(s) that the lodgement has triggered.
  • If a smart audit fails for a reason other than the smart audit rule that it triggered then, where possible, the subsequent follow on audit will be based on the same criteria that caused the fail.
  • If an Energy Certificate is called for a smart audit and triggered multiple smart audit rules, then it will be audited against them all but only counted as one smart audit.
  • Should a member pass a smart audit, but, in a subsequent month, trigger the same smart audit rule, they will not need to be audited as they have already demonstrated their competence on the issue.
Important Note: An update to the Smart Rules (v1.8) will be made live on the 1st July 2025. You can view the upcoming changes to smart rules here.
