NatHERS Assessors

NatHERS Assessors are professionals who have completed relevant training and belong to an Assessor Accrediting Organisation (AAO). They must have a basic understanding of construction, building thermal performance and applicable regulations.

Accredited assessors receive ongoing technical support, access to Continuing Professional Development (CPD) training, and regular newsletters. They can also list their services on AAO websites to help generate business.

Learn more about AAOs and assessor training, including becoming accredited for Whole of Home assessments on the Assessor Toolkit page.
