Residential Efficiency Scorecard tool to be trialed nationally

The Residential Efficiency Scorecard (the Scorecard) provides an energy star rating for homes. Assessments and information on ways to reduce energy costs and increase home comfort are tailored specifically for each home and are delivered by accredited assessors.

Scorecard assessments are available in Victoria now and a national version of the Scorecard tool (the National Scorecard) and assessor processes will be field tested during 2021. This means there are opportunities for assessors and householders across Australia to participate.

For potential assessors outside of Victoria, round 1 of an Expression of Interest process is open from 1 December 2020 until close of business on 15 December 2020. If sufficient successful applications are received in Round 1, there will be no additional rounds at this stage.

The Commonwealth, State and Territory Governments are funding the extension of the Nationwide House Energy Rating Scheme (NatHERS) to include existing homes. The NatHERS Administrator is examining the Scorecard program to inform how NatHERS could be extended to support in-home assessments for existing homes.

The results of the field trial will inform the work to extend NatHERS and include consideration of a national rollout of the National Scorecard tool from mid-2021, ahead of the National Scorecard seeking accreditation under NatHERS for existing homes.

The National Scorecard covers Australia and is based on the Victorian Scorecard and previous national pilots.

Frequently Asked Questions (FAQ's)

The field trial will test a nationally available and voluntary National Scorecard rating. From early 2021, assessments will be available across Australia from accredited assessors and participants will be surveyed on their experience.

The field trial will include:

  • nationally available assessor training and accreditation
  • use of the expanded National Scorecard tool covering all climate zones
  • nationally branded Scorecard supporting materials available for use by assessors. This includes fact sheets and promotional materials. (The branding on these materials are likely to change after the National Scorecard tool seeks accreditation under NatHERS and will be part of the transition period).

If you are interested in becoming an assessor and are located in Victoria, see the ‘I want to become an assessor’ page. To support quality and protect consumers, only accredited assessors can deliver Scorecard assessments.

Opportunities to become an accredited assessor are available across Australia.

Round 1 of an expression of interest process for potential new assessors located outside Victoria, which ran from 1 December 2020 until 15 December 2020 is now closed.

Before you can sit the Scorecard examination and become an accredited assessor, you will need to:

  • Occupational Health & Safety (OH&S) course:  Complete and pass the course, “CPPHSA4005A - Minimise health, safety and security risks when assessing home sustainability” at your expense (if you have not previously completed the course).
  • Public liability insurance cover (minimum $10 million):  Provide proof of public liability insurance with a minimum cover of $10 million.  This insurance cover should be for any death, injury, damage or loss to other persons arising from the carrying out of Scorecard ratings for an amount of not less than ten (10) million dollars for any single occurrence.
  • Professional indemnity insurance cover (minimum $2 million):  Provide proof of professional indemnity insurance with a minimum cover of $2 million. Assessors must maintain such insurance current for the duration of the Scorecard Assessor Agreement [MS Word Document - 84.4 KB] and six (6) years thereafter, and for an amount of not less than two (2) million dollars for any single occurrence.  If you are working through a business or not-for profit organisation, you may provide evidence of the insurance that they hold, showing that it covers you. This should include a copy of the policies and a letter or email that identifies each of the policies, the level of coverage in dollar amount for that policy, the policy number and a statement that the named assessor is covered by that policy.

It is proposed that the national version of the Residential Efficiency Scorecard, (the National Scorecard) will seek accreditation under the Nationwide House Energy Rating Scheme (NatHERS) for voluntary use. For more information visit

If you are an accredited assessor within Victoria, you can now participate in the trial and deliver assessments across Australia as well as Victoria. Some assessment materials, such as fact sheets, may change to become more relevant to a national audience and you will be informed of these changes. If you are an accredited assessor outside of Victoria, you are invited to participate in the national trial.

All assessments completed during the national trial period will be included in the evaluation and you are also encouraged to provide feedback on the field trial. Accredited assessors do not need to submit an expression of interest to participate in the trial.

National assessments are available across Australia from January 2021. Find a Scorecard assessor here. All National Scorecard assessors are accredited against six quality principles to ensure you receive the best service.

Households pay for a Scorecard assessment with fees set by the Scorecard assessor. In some cases home assessments under the National Scorecard field trial may be partly funded and offered at a reduced rate.

Extending NatHERS to existing homes will include establishing the software accreditation processes (for the National Scorecard and any future tools), assessor accreditation processes (for in-home assessments), and elements of scheme management such as NatHERS trademarks, certificates and logos.

The Scorecard tool and program will inform this work, along with work from the New South Wales Government to identify future markets that could utilise energy ratings and tools for existing homes. A draft of the NatHERS requirements will be released in mid-2021, with the final requirements and Scheme design to be delivered in early 2022.

The Scorecard cannot be used for regulatory purposes under the Building Code of Australia. It is proposed that in future the National Scorecard will be accredited under the Nationwide House Energy Rating Scheme (NatHERS) as a voluntary tool. Some NatHERS tools are accredited for regulatory purposes under the Building Code of Australia. At this stage it is not intended that the Scorecard will seek accreditation for regulatory purposes under the Building Code of Australia.
