Home Energy Rating for existing homes

The assessment is $300 + GST, or $330 including GST. It includes the onsite assessment, the accredited existing-home rating and property-specific improvement guidance. Rebates or discounts are not assumed in this fixed price, and appointment availability is confirmed for your address.

Home Energy Rating is the current public name for the national framework. The existing-home service follows its own accredited assessment pathway, using information about the home as it stands. Accreditation for new-home work alone does not establish accreditation for the existing-home stream.

The assessor collects the measurements, construction and appliance information needed for the rating, supported by accessible observations and evidence. You can explain comfort issues and planned upgrades. The findings are then modelled through the accredited process; the onsite visit is one part of producing the final rating.

Provide available plans, renovation details, insulation or glazing information and appliance specifications. Arrange safe access to the areas the assessor needs to inspect and tell us about access limitations beforehand. Unknown or inaccessible features must be handled under the assessment method rather than treated as verified facts.

The scheme requires the official Client Information and Consent Form for each existing-home assessment. It explains how assessment information and rating records are used, including the scheme's publication and opt-out arrangements. Consent to the rating is separate from permission to share your details for another service or trade referral.

You receive the applicable Home Energy Rating and Star Rating documentation, together with property-specific energy and comfort improvement guidance. The final documents are provided through a secure shareable link with a downloadable PDF. They describe the assessed home and the modelled result, rather than certifying rental safety.

The final documentation is emailed the same day that the modelling and certification are complete. Some work takes place after the onsite visit, and missing evidence may need to be resolved before the rating can be issued. We do not describe the inspection date as the certificate issue date unless the assessment is actually complete.

The rating and guidance help identify improvement opportunities, but modelled performance is not a guaranteed bill reduction. Actual energy use depends on occupancy, weather, tariffs, appliance settings and how the home is used. Any proposed upgrade should be considered against your circumstances and the assessment findings.

An existing-home energy rating is distinct from new-home building-approval assessments and rental safety checks. It does not replace an electrical, gas, smoke alarm or minimum standards report. Tell us the purpose of the assessment so the correct service is selected.

Choose the existing-home rating when you want formal accredited rating documentation and the associated modelling. Choose the onsite energy visit for practical observations and improvement advice without a certificate. Both can help identify priorities, but only the accredited rating service provides the applicable formal rating documents.

The official consumer service is Home Energy Rating. People still search for a NatHERS existing home assessment or NatHERS rating for an existing home, but the result for a completed home should use the current Home Energy Rating and Star Rating names.

Residential Efficiency Scorecard is a legacy search term for the former service. Home Energy Rating launched nationally on 1 July 2026 and is the current official consumer pathway for rating an existing home.

It provides a Home Energy Rating from 0 to 100+, a Star Rating from 0 to 10, estimated annual energy use and upgrade guidance for the assessed home.

Official guidance says an existing-home visit usually takes about two to three hours. A larger or more complex home can take longer, and safe access to the relevant areas matters.

The existing-home assessment is $300 + GST ($330 including GST). Australian Energy Assessments confirms location, access and the service before booking. Funding eligibility is checked separately and is not assumed in this price.

It can be useful when you want an independent picture of how the home performs and a sensible order for upgrades. It is not a promise of lower bills, a building approval or a construction quote.

No. An existing-home rating cannot demonstrate National Construction Code compliance. If a major renovation must demonstrate compliance, official guidance says it needs the relevant new-home certificate pathway. The approval authority determines the evidence required for the project.
