Rates, programme terms, incentives and eligibility can change; consult the named official source and current provider terms. A scenario does not establish household eligibility. Australian vehicle references are dated, exact vehicle examples, not a live Green Vehicle Guide feed. Public energy plan data is separate from private meter or customer data. VEU model extracts are historical reference data, not complete live registers: the retained hot-water export is dated 19 August 2025. Confirm current product status with the ESC registry and an accredited provider. Archived articles retain their publication dates and review status. Only guides explicitly marked “Sources checked” have completed the displayed source review; copy corrections elsewhere do not mean every archived fact has been revalidated. - [Editorial review records](https://www.voltarocks.com/editorial/reviews.json): Article-level status and checked sources. - [Sitemap](https://www.voltarocks.com/sitemap.xml): Canonical public pages.
