Electricity Bill Doubled? How to Force a Bill Review and Meter Test (and Stop Disconnection While You Dispute It)

Last quarter was $480. This quarter is $1,140, with the same two adults, the same fridge and no pool. The retailer’s answer, after 35 minutes on hold, is “your usage has increased” and an offer to spread it over six months. The bill itself shows an estimated read, a tariff you don’t remember agreeing to, and no sign of the concession you registered last year.

You don’t have to accept “usage” as an explanation. Energy retailers in Australia operate under rules that give you the right to have the bill reviewed, the meter tested, and the calculation explained line by line, and that prohibit disconnection while a genuine dispute is unresolved. The retailer’s internal complaint is the mandatory first step; the state energy ombudsman is the second, and it’s free and binding on the retailer.

Your rights

In New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory, the National Energy Retail Law and the National Energy Retail Rules (NERR) apply. Victoria, Western Australia and the Northern Territory have their own codes with similar protections (see By state). Under the NERR:

• Bill review (r 29). You can ask the retailer to review a bill. While it does, you must pay the lesser of the disputed bill’s undisputed portion or an amount equal to your average bill, and the retailer can’t treat the disputed amount as overdue.
• Meter test. As part of a review you can require the meter to be tested. If the meter is faulty, the bill is corrected and the test is free; if it’s accurate, the retailer may pass on the reasonable cost of the test, so ask for the cost up front.
• Bills must be based on actual reads where possible. Estimated bills must be clearly marked, and you can supply a self-read to correct an estimate.
• Overcharging (r 31). If you’ve been overcharged, the retailer must refund or credit the amount within a set period once identified.
• No disconnection while a complaint is open (r 116). A retailer must not arrange disconnection for non-payment while you have an unresolved complaint about the bill with the retailer or with the ombudsman, or while you’re complying with a payment plan.
• Payment plans and hardship. If you’re struggling to pay, you’re entitled to a payment plan based on your capacity to pay, and access to the retailer’s hardship program with protections from disconnection.

By state

• New South Wales. NERR applies. Complaint to the retailer, then the Energy & Water Ombudsman NSW (EWON). New South Wales Energy Accounts Payment Assistance vouchers via the retailer for hardship.
• Victoria. Outside the national framework. The Essential Services Commission’s Energy Retail Code of Practice covers billing, bill review, meter testing, the payment difficulty framework and disconnection limits; the Victorian Default Offer caps standing-offer prices. Complaint to the retailer, then the Energy and Water Ombudsman (Victoria) (EWOV).
• Queensland. NERR applies. Retailer first, then the Energy and Water Ombudsman Queensland (EWOQ).
• Western Australia. Outside the national framework. The Code of Conduct for the Supply of Electricity to Small Use Customers 2022 covers billing accuracy, bill review, meter testing, payment difficulty and disconnection. Retailer first, then the Energy and Water Ombudsman Western Australia.
• South Australia. NERR applies. Retailer first, then the Energy and Water Ombudsman SA (EWOSA).
• Tasmania. NERR applies (with Tasmanian modifications). Retailer first, then the Energy Ombudsman Tasmania.
• Australian Capital Territory. NERR applies. Retailer first, then the ACT Civil and Administrative Tribunal (ACAT), which performs the energy ombudsman function in the Territory.
• Northern Territory. Outside the national framework. The Utilities Commission’s Electricity Retail Supply Code and your retailer’s customer contract govern billing and disconnection. Retailer first, then the Ombudsman Northern Territory.

The Claim Done document asks your state first and drafts the dispute to the NERR, the Victorian Code, the Western Australia Code or the Northern Territory Code, and names the right ombudsman.

What to do right now

1. Read the bill properly. Is the read actual or estimated? What are the start and end reads and the number of days? Has the tariff, the daily supply charge or the meter type changed? Is your concession applied? Is there a “catch-up” or “adjustment” line?
2. Take your own meter read and a photo today. Compare it to the bill’s end read. A big gap in either direction is a finding on its own.
3. Pull the last four bills and lay the usage (kWh) side by side. Usage that doubled with no change in occupancy or appliances is the case for a meter test.
4. Lodge a written complaint with the retailer (not a phone call). Request a formal bill review, a meter test with the cost disclosed in advance, an itemised explanation of the calculation, confirmation that the disputed amount will not be treated as overdue, and written confirmation that no disconnection will be arranged while the complaint is open. Ask for a complaint reference number.
5. Give a deadline and escalate. Retailers have their own complaint timeframes; if you don’t have a substantive answer within a reasonable period, or you don’t accept it, go to the ombudsman with the reference number and your letter.

The things that actually cause a doubled bill

Most doubled bills turn out to be one of a handful of things: a string of estimated reads followed by an actual read (the “catch-up”); a smart meter installed mid-period with the old and new meter both billed; a wrong tariff after a plan change or a transfer you didn’t authorise; a concession dropped when your card was renewed; a solar feed-in credit that stopped when the inverter tripped; or, occasionally, a meter fault or a neighbour’s circuit wired through your meter. Each has a paper trail the retailer holds and you don’t, which is why the written request for an itemised explanation matters more than the phone call. A meter test is the right ask when usage rose with nothing else changing; a tariff and read history is the right ask when the kWh are the same but the dollars aren’t.

Who to complain to

Your retailer in writing first. Then your state energy ombudsman: EWON, EWOV, EWOQ, EWOWA, EWOSA, Energy Ombudsman Tasmania, ACAT (Australian Capital Territory) or Ombudsman Northern Territory. The Australian Energy Regulator (national framework states) or the Essential Services Commission (Victoria) for systemic rule breaches, though they don’t resolve individual bills. A financial counsellor (National Debt Helpline 1800 007 007) for hardship arrangements.
