A bill shows consumption an average household couldn't plausibly generate. Real cases show faulty meters can and do cause exactly this — and there's a clear, free path to get one tested.
Start with your retailer's billing review
Requesting a bill review from your energy retailer is one of the most relied-on consumer protections in the National Energy Customer Framework. Retailers must conduct these reviews as part of their complaints and dispute resolution procedures. As part of a review, you can ask your retailer to arrange a meter reading check, request the underlying metering data, or ask the metering coordinator to test the meter directly.
Real cases where meters were the problem
State energy and water ombudsman case files document genuine faulty-meter outcomes: in one water case, a faulty dial caused a 10,000 kilolitre overbilling worth over $23,000, refunded in full once independent testing confirmed the fault, including reimbursement of the test cost itself. In another electricity case, a retailer's own app showed an implausible single-day consumption spike, which triggered a formal review of the underlying meter data.
If your retailer's review doesn't resolve it
Every state and territory has its own free, independent energy and water ombudsman scheme: Energy & Water Ombudsman NSW (EWON), Energy and Water Ombudsman Victoria (EWOV), and equivalent bodies in Queensland, South Australia, Western Australia and the ACT. These schemes can investigate billing disputes, request the retailer's meter data and test results, and order remedies — including bill corrections and refunds — at no cost to you.
How to build your case
- Request a formal billing review from your retailer, specifically asking whether the bill is based on an actual or estimated reading.
- Ask directly for a meter accuracy test if the consumption figure seems physically implausible for your household.
- Keep copies of all bills, correspondence, and any app/portal usage data showing the disputed period.
- If the retailer's review doesn't resolve it, or drags on with the metering provider unresponsive, escalate to your state's energy and water ombudsman.
- Ask the ombudsman to review both the billing and the metering data together — as case history shows, the two often need to be checked in parallel.
What this means practically
- An implausible consumption spike is a valid reason to request an independent meter test, not just accept the bill.
- If a meter is found faulty, retailers have refunded overcharges in full, including the cost of the test itself, in documented cases.
- Delays in obtaining metering data from a separate metering provider are a known friction point — don't assume silence means your dispute has been dropped.
- Every state has its own energy and water ombudsman — check which one covers your address before lodging a complaint.
