Assessor Register

This register lists assessors with an active accreditation to undertake NatHERS for existing homes assessments. It enables assessor credentials to be verified by the public. Individuals will be removed if their accreditation is cancelled or currently suspended.

The register is maintained by the NatHERS Administrator and published in accordance with the Privacy Act 1988 (Cth), DCCEEW’s Privacy Policy, the NatHERS Information Collection, Storage and Dissemination Policy, and the consent of each assessor. For more information about privacy, please email admin@nathers.gov.au.

Contacting assessors

If an assessor has opted in, details may include contacts, and the states and/or territories they work in. 

The register is not intended to act as a booking or advertising service. However, the public may use the register to contact assessors independently for assessments and are encouraged to seek multiple quotes when engaging professional services. 

For questions about accreditation or use of this register, please contact the NatHERS Administrator: admin@nathers.gov.au
