NatHERS Certificate Samples
Across Australia, all Nationwide House Energy Rating Scheme (NatHERS) ratings are presented on a certificate or a non-accredited report.
These show key details about the dwelling, and from 2022, will also provide new information for households on the greenhouse gas emissions of their home, the costs and energy used by all its major appliances, and the impact of solar and batteries.
The certificate will be in one of two formats:
- A certificate that displays the NatHERS logo and can be printed in colour –produced by accredited assessors
- A non-accredited report without the NatHERS logo and only available in black and white – produced by non-accredited assessors.
They have been designed so that owners, builders, certifiers and regulatory authorities can understand and easily check the home’s rating. The QR code, in particular, is important. When scanned, it takes the user to the original certificate that is stored on a secure website.
The data from these certificates go into the CSIRO Australian Housing Data portal (AHD). Furthermore, the fees from the certificates contribute to funding the NatHERS Scheme.

NatHERS Whole of Home Guidance Note
The Whole of Home Guidance Note contains advice to assist assessors undertaking a Whole of Home assessment. It should be read in conjunction with the NatHERS Technical Note.
The Guidance Note is initially issued as a separate document with the intention of incorporating it as a chapter into the NatHERS Assessor Handbook in the future. This strategy will allow the Guidance Note to be rapidly updated to address any issues that arise once assessors start to undertake Whole of Home assessments.
