Energy stars vs labelled kWh
Understand how Australian appliance energy stars differ from labelled annual kWh, when comparisons are valid and why neither predicts your exact bill.
Read evidence guideRead the record.
Keep its limits.
Six practical guides explain what official appliance evidence can support, where comparisons break down and which questions require a different source.
Published by Lasting Index editorial operation · Reviewed 23 August 2026Australian appliance registrations
Read Australian GEMS appliance registrations correctly: model identity, registration number, family coverage, dates, energy fields and important limits.
Read evidence guideFrench durability vs repairability
Understand France's durability and repairability indices, how reliability changes the durability score and why exact model and calculation date matter.
Read evidence guideRecall matching limitations
Learn how appliance recall matching works, why exact model and market matter, what a missing match means and when to follow an official safety notice.
Read evidence guideRepair-or-replace methodology
See the assumptions, formulas, safety gates and exclusions behind the Lasting Index repair-or-replace annualised-cost comparison.
Read evidence guideExact models and regional variants
Why exact appliance model codes, market and source scope must stay together, and why similar regional variants are not merged without evidence.
Read evidence guideWhich record answers your question?
Start with the decision you need to make, then use only evidence collected for that purpose. These records are complementary; they are not interchangeable scores.
| Question | Evidence to inspect | What it cannot prove | Market |
|---|---|---|---|
| How much labelled energy does this model use? | Energy stars and labelled kWh | Your household bill, repair rate or lifespan | Australia |
| Is this the registered appliance identity? | Registration number, model and supplier record | Current retail availability or reliability | Australia |
| What does the statutory durability score contain? | Durability, reliability and repairability components | A Lasting Index test or guaranteed service life | France |
| Does an official notice cover this exact model? | Recall identity and affected scope | That no match means the appliance is safe | Notice jurisdiction |
| Should I compare a repair quote with replacement? | Transparent annualised cost assumptions | A safety verdict or reliability prediction | User scenario |
| Can two regional model records be treated as one? | Exact identity and manual relationship evidence | Equivalence from a similar name alone | Market locked |
Editorial boundary
No rankings hidden inside a guide.
Each guide separates official facts, Lasting Index interpretation and unresolved evidence. No guide turns registration into reliability, absence of a recall into safety, or a user-entered cost scenario into a recommendation.
