The wide range reflects real differences in what you are actually getting, and understanding those differences helps you make a smarter decision before you engage anyone. What Is a NatHERS Certificate and Why Do You Need One? NatHERS stands for Nationwide House Energy Rating Scheme. It is Australia's framework for assessing the thermal performance of residential buildings. An accredited assessor creates a 3D model of your home using approved software, simulates how the building heats and cools across a full year of climate data, and produces a star rating from zero to ten based on the energy required for heating and cooling. The certificate confirms three ...

The NatHERS Existing Homes Scheme: A New Tool for Energy Ratings

Australia’s housing landscape is undergoing a transformative shift with the expansion of the Nationwide House Energy Rating Scheme (NatHERS ) to include existing homes.  This landmark initiative, set for full rollout by mid-2025, aims to improve energy efficiency, reduce household costs, and support Australia’s transition to net-zero emissions.  For homeowners, renters, and industry professionals, this marks a pivotal step toward sustainable living.

Most Australian homes were built before modern energy standards, with over 10.8 million dwellings averaging below three stars in energy performance.  The new NatHERS Existing Homes Scheme addresses this gap by introducing standardised energy assessments that evaluate a home’s thermal performance, fixed appliances (e.g., heating/cooling systems), a...
