Once an Accredited Assessor has submitted the rating for your premises, our technical officers or independent parties will perform a Level 1 and Level 2 (if selected) audit on the submitted rating.
A Level 1 audit is conducted in 100% of NABERS rating applications. Our technical team carry out these audits to ensure NABERS Assessors have correctly applied the rules, and not made any data-entry errors.
Please allow 10 working days for our team to conduct a Level 1 audit, as well as the time required for responding to any questions.
A Level 2 Audit is conducted in 5% of all NABERS submitted ratings as well as 5% of ratings used to obtain a Building Energy Efficiency Certificate (BEEC) under the Commercial Building Disclosure. A panel of external Auditors conduct the Level 2 audits.
The Level 2 audit process involves re-rating the premises, using documentation provided by the Assessor who conducted the original rating. From time to time, this can lead to a NABERS rating being revised or withdrawn. Assessors can also receive sanctions for unsatisfactory performance as identified through this process.
Occasionally, Assessors will be notified of a Level 2 audit for one of their ratings, and will be expected to provide their complete supporting documentation within 10 working days. Following their review, the Auditor will report their findings, and the Assessor given a Right of Reply if any contentious issues are raised. NABERS will complete the final determination of the audit outcome.
The time taken to complete a Level 2 audit can vary because of several factors including:
Type and level of complexity of the original rating
Quality and completeness of the documentation provided for audit
The Assessor’s level of cooperation with the external auditors during different stages of the audit process.
