An Energy Efficiency Rating (EER) is a standardised measure of a home’s passive energy performance, used to show how well the property manages heating and cooling energy compared with other homes. In the ACT, it is a mandatory disclosure requirement when selling a property — meaning sellers must provide an accredited assessor’s EER to buyers as part of the sales documentation.

This rating system has been in place since 1999, making the ACT’s scheme one of the longest-running mandatory energy disclosure systems for residential property.

The EER process involves a qualified building assessor evaluating the property using specialised energy modelling software. The outcome is an EER report that helps owners and prospective buyers understand the expected energy performance of the home.

ACT Building Approvals provides property inspections conducted by NatHERS accredited and licenced Cola Class A Building Assessors that are endorsed to use all first- & second-generation Energy Efficiency software.

*Sellers should exercise caution when using non-accredited NatHERS Assessors, NatHERS Assessors undergo Continuing Professional Development (CPD) training throughout their professional lives unlike Cola Licenced Building Assessors. Energy efficiency rating statement that are false or misleading can cost the seller .5% of the sale price.
