Assessors and Assessor Accrediting Organisations
NatHERS Accredited Assessors
NatHERS Accredited Assessors are professionally recognised energy assessors who are qualified in conducting house energy ratings using NatHERS Accredited Software. They follow an Assessor Code of Practice and are provided ongoing support and guidance to ensure they provide high standards of quality and service delivery.
It is recommended that owners and builders use a NatHERS Accredited Assessor when getting a home’s energy rating determined.

Assessor Accrediting Organisations
Assessor Accrediting Organisations (AAOs) are professional organisations with responsibility for accrediting assessors and ensuring they deliver reliable and consistent energy ratings.
There are three AAOs currently operating in Australia:
|ABSA||Design Matters National||HERA|
AAOs operate in accordance with the Protocol for Assessor Accrediting Organisations.
The 2016 AAO Protocol was released in March 2016, with effect from 1 July 2016.
In mid-2020, Section 3 of the Protocol was amended and Appendix B was added. These changes reflect updates in registered training courses and the new process to obtain accreditation in additional NatHERS software tools. This changes are effective as of 7 July 2020.
The entire AAO Protocol (2016) is under review and expected to be released in November 2020 after stakeholder consultation.
