Two layers of protection
Two frameworks govern energy billing in Australia:
- The Australian Consumer Law (ACL) applies nationwide. It requires services to be provided with due care and skill and bills to be accurate.
- The National Energy Customer Framework (NECF) adds detailed retailer obligations on top. NECF applies in the ACT, Tasmania, South Australia, New South Wales, and Queensland.
Victoria has its own harmonised Energy Retail Code with similar protections. Western Australia and the Northern Territory use local legislation (the WA Code of Conduct and the NT Electricity Reform Act). Your rights are broadly equivalent; only the specific regulator differs.
Common billing issues
Estimated versus actual meter reads
Retailers can estimate a read when they can't access the meter, but they must correct the bill once an actual read is obtained. If you have a smart meter, your usage data is transmitted remotely and estimates should be rare. Submit your own read via your retailer's app or website and ask for a recalculation.
Wrong tariff applied
Check your bill against the Reference Price published by the AER (or the ESC in Victoria). If your retailer has moved you off a promotional rate without adequate notice, or applied a time-of-use tariff to a meter that doesn't support it, that is a retailer error — not your overpayment.
Solar feed-in errors
Solar feed-in tariff rates and export caps are a common source of errors. Your bill must show exported kWh and the feed-in rate applied. Cross-check against your inverter's monitoring app.
Disconnection and late fees
Retailers must follow strict notice and hardship procedures before disconnecting. Charges for disconnection or late payment after an inadequate notice period can be reversed.
How to dispute
- Contact your retailer in writing. Describe the disputed charges and ask for a detailed explanation and a recalculation where appropriate.
- Keep paying the undisputed portion of the bill so you stay current on amounts you agree you owe.
- If unresolved after a reasonable period (usually 20 business days), escalate to the state Ombudsman.
Energy and Water Ombudsman by state
- NSW — EWON
- VIC — EWOV
- QLD — EWOQ
- SA — EWOSA
- WA — Energy and Water Ombudsman WA
- TAS — Energy Ombudsman Tasmania
- ACT / NT — ACAT (ACT) and the NT Ombudsman respectively
The Ombudsman service is free for consumers and its decisions are binding on the retailer up to a monetary limit that varies by state.
