In Brief
The Residential Efficiency Scorecard has been used in Australia to help assess the energy performance and comfort of existing homes. However, the official Scorecard program is closing on 23 June 2026 as Australia transitions toward NatHERS for existing homes and the broader Home Energy Rating framework.
This does not mean the underlying idea is disappearing. The need to understand existing home comfort, household energy use and practical upgrade pathways is becoming more important. What is changing is the language, framework and future assessment pathway.
Understanding the Transition
The Residential Efficiency Scorecard has played an important role in helping homeowners understand how existing homes perform. It has provided a way to look at energy use, comfort and improvement opportunities in homes that have already been built.
Australia is now moving toward a more nationally consistent approach through NatHERS for existing homes and Home Energy Rating language. NatHERS has historically been best known for new home energy ratings, but it is expanding to include existing homes.
For homeowners, this can feel like a terminology shift. The familiar Scorecard name is winding down, while Home Energy Rating and NatHERS for existing homes are becoming more central. The practical question remains the same: how does this home perform, and what improvements may help it become more comfortable and efficient?
Why It Matters
The transition matters because many people still search for Residential Efficiency Scorecard when they want to understand existing home performance. Homeowners, buyers, lenders, real estate professionals and project teams may all use slightly different language for the same broad need.
If the terminology is unclear, people may not know whether they need a Scorecard, a Home Energy Rating, a NatHERS existing homes assessment or general energy efficiency advice. This is why a clear bridge page is useful. It helps explain what is changing without losing the practical purpose of the original Scorecard idea.
The shift also reflects a broader change in the housing market. Existing homes are increasingly being viewed through the lens of comfort, energy use, upgrade planning, emissions reduction, finance readiness and long term resilience.
How It Relates to the Residential Efficiency Scorecard
The Residential Efficiency Scorecard remains important as a public facing term because it describes the problem in simple language. It tells homeowners that the home’s efficiency can be assessed and improved.
Even as the formal program closes, the Scorecard language still helps people understand the relationship between comfort, energy use and practical upgrades. A cold home, a hot home or a home with high energy bills may not need one isolated product. It may need a clearer understanding of building fabric, services, air leakage, glazing and household energy demand.
The Residential Efficiency Scorecard Knowledge Hub uses this language as a bridge. It helps visitors who are searching for Scorecard information move into the newer conversation around Home Energy Rating, existing home performance and future ready upgrade pathways.
How It Relates to Home Energy Rating or Existing Home Energy Assessments
Home Energy Rating is becoming the broader language for understanding the energy performance of existing homes. It is connected to the expansion of NatHERS into established housing and the development of clearer rating information for homes that are already built.
This matters because existing homes are different from new homes. A new home rating assesses a proposed design before construction. An existing home rating or assessment looks at a real property with real materials, services, renovation history and comfort issues.
As the Scorecard program closes, the future pathway is expected to sit more clearly with NatHERS for existing homes and Home Energy Rating. For homeowners, the most important step is to understand which current pathway applies at the time they need an assessment.
Practical Considerations for Australian Homes
For homeowners, the first practical consideration is timing. If someone is specifically looking for a Residential Efficiency Scorecard, they should be aware that the official program closes on 23 June 2026 and that transition arrangements may affect assessment availability.
The second consideration is terminology. A homeowner may search for Scorecard, but the current industry pathway may use Home Energy Rating or NatHERS for existing homes language. This can be confusing, but the underlying purpose remains focused on existing home performance.
The third consideration is the home itself. Regardless of the program name, the assessment conversation will usually involve comfort, building fabric, insulation, glazing, draughts, heating, cooling, hot water, appliances and upgrade opportunities.
The fourth consideration is future use. Existing home energy ratings may become increasingly relevant for renovation planning, household energy upgrades, finance conversations, property transactions and government programs. This makes it useful to understand the shift early rather than treating it as a technical naming change.
How Certified Energy Can Help
Certified Energy helps homeowners, property professionals and project teams understand residential energy performance in clear, practical and technically credible language. Our work sits across Residential Efficiency Scorecard knowledge, Home Energy Rating, NatHERS, Whole of Home, BASIX and broader residential performance advice.
As the industry language changes, our role is to help translate the transition into practical meaning. We help clarify what the Scorecard has represented, how it connects to existing home performance and where Home Energy Rating and NatHERS for existing homes fit into the future.
If you are trying to understand whether the Residential Efficiency Scorecard is still relevant, the most useful starting point is the wider existing homes conversation: how the home performs now, what affects comfort and energy use and which upgrade pathway makes sense next.

FAQ Section
Is the Residential Efficiency Scorecard still used in Australia?
The Residential Efficiency Scorecard program is closing on 23 June 2026. During the transition period, Scorecard assessments have continued to be available, but projects and programs will need to move toward NatHERS for existing homes after closure.
Why is the Residential Efficiency Scorecard closing?
The Scorecard is being phased out as Australia moves toward NatHERS for existing homes and the broader Home Energy Rating framework.
What is replacing the Residential Efficiency Scorecard?
NatHERS for existing homes and Home Energy Rating are becoming the future pathway for existing home energy performance ratings in Australia.
Does the Scorecard language still matter?
Yes. Many homeowners and property professionals still recognise or search for Residential Efficiency Scorecard, so the language remains useful for explaining existing home performance and connecting people to the newer rating framework.
Is this the same as a new home NatHERS rating?
No. A new home NatHERS rating assesses a proposed residential design before construction. Existing home ratings focus on homes that have already been built.
How can Certified Energy help with the transition?
Certified Energy can help homeowners and project teams understand the changing language around Residential Efficiency Scorecard, Home Energy Rating and NatHERS for existing homes, and how these relate to comfort, energy use and practical upgrade planning.
