Overview

What is a Home Energy Rating assessment?

A home energy assessment looks at how your home uses and loses energy, using the House Energy Rating Scheme (HERS), the framework used across Australia to rate home energy performance. Home Energy Rating has long been used to rate the design of new homes, and has recently been expanded to rate existing homes as well.

The assessment is carried out by an accredited assessor. It is one of the options available through Home Energy Saver, and it takes the guesswork out of choosing upgrades by showing you which improvements will help your home the most.

Existing home assessments use the same national scheme and star scale as new homes, but are a newer, separate pathway suited to homes that are already built and lived in.
