Tick off the eligibility, quote, contract, VPP and installation-day checks before you accept a home battery quote.

Work through this checklist with each quote in front of you. It follows the conditions the Clean Energy Regulator sets for battery STCs, the obligations it places on solar and battery retailers, and your rights under the Australian Consumer Law.
How to use it. Tick an item only when you can point to it in writing: on the quote, the contract, the product's spec sheet or an official lookup. A verbal promise does not count. Unticked items are the questions to send back to the installer before you accept.
Why it matters. The STC discount depends on eligibility conditions that the installer and retailer must meet; if a battery is not on the approved list, the installer is not accredited, or a battery has already been claimed at your address, the discount you were quoted may not be available. Missing line items such as switchboard work are the most common reason a final invoice differs from the quote.
Limits. This checklist is general information. It does not replace an installer's site assessment or advice from your state fair trading agency. For detail, read the quote comparison guide, the eligibility rules and where to get help.
