High electricity bill? Check usage, tariffs and the meter

The total on the front page cannot explain the increase

An electricity bill that doubles can feel like proof that something has gone wrong. The total alone does not tell you what changed. It may contain an old balance, cover more days or use a different price. It can also contain an error. The useful first step is to break the total into smaller questions.

Gather the current bill, the previous bill and, if available, a comparable bill from a similar season. Keep the full pages, because meter information, rate changes and adjustments may sit behind the headline amount. If you use an online portal, download a copy for your private records before the information changes.

Do not post the full bill publicly to crowdsource an answer. It can expose your address, account identifiers, usage patterns and payment details. A short private comparison with the retailer is usually more useful than a screenshot with sensitive information still visible.

Compare days and daily usage before dollars

Find the number of days in each billing period and the energy used, usually expressed in kilowatt-hours for electricity. Divide usage by days to compare like with like. A longer bill can have a higher total even when daily consumption barely changes.

Here is a fictional example. A previous bill covers 60 days and records 600 kWh, or 10 kWh a day. A new bill covers 90 days and records 1,080 kWh, or 12 kWh a day. Usage has increased by 80% across the whole bill but by 20% on a daily basis. The household still needs to investigate the rise, but those are different questions.

Now compare the prices and fixed supply charges. Do not divide the whole bill by kWh and assume the result is the usage tariff. Fixed charges, different time bands, credits and adjustments can make that shortcut misleading. Use the actual line items.

Check whether the bill is estimated, actual or adjusted

Energy Made Easy recommends checking whether the bill uses an estimated or actual meter reading. An estimate can be above or below eventual measured use. A later bill may then contain an adjustment. A smart meter does not make every possible data or billing problem impossible.

Ask the retailer which readings or interval data were used, what period an adjustment covers and whether an earlier estimate explains the change. Keep the answer with the relevant bills. If the explanation uses a meter number or service identifier, ask the provider to confirm it matches your property through its secure process.

For a basic accumulation meter, there may be a self-read option. Follow the retailer’s instructions about eligibility and timing. Do not assume the same process applies to a smart meter. Never open a meter enclosure, break a seal or touch equipment to obtain evidence.

Use local guidance for backbilling and payment protections

Energy rules and complaint arrangements are not identical everywhere. For example, EWOV’s Victorian estimated-bill factsheet discusses local backbilling limits and exceptions. Western Australia has its own framework. A limit mentioned in a Victorian article should not be repeated as a national rule.

Ask which rule applies to your account and the reason for the adjustment. Relevant questions include the period covered, why the original amount was wrong, what caused the delay and what payment options are available. If you receive a collection or disconnection warning, tell the retailer and appropriate dispute service about the urgency rather than waiting for a routine email reply.

Do not assume that opening a complaint automatically cancels the entire bill or every payment obligation. Ask the retailer or local ombudsman what to pay while the dispute is considered and what protections apply in your circumstances. Get a clear record of the instruction.

Separate a tariff problem from a consumption problem

A tariff is the pricing structure used for your energy. Check whether your rates changed, an introductory discount ended, a time-of-use structure began or a concession or solar credit is missing. Ask for the date and basis of any change you cannot reconcile with your documents.

If the rates are correct but consumption increased, list what changed at home. Heating or cooling, an extra person, a new appliance, altered work patterns or lower solar output can affect the picture. Energy & Water Ombudsman NSW identifies these as possible explanations alongside billing errors and longer billing periods.

You do not need to diagnose every appliance yourself before asking for help. Record observations rather than conclusions: “heating used more evenings” is stronger than “the heater caused all of the increase” unless you have evidence. If equipment appears unsafe, stop treating it as a budgeting experiment and use a suitable professional.

A fictional tariff comparison that avoids a false conclusion

Suppose a household’s entered flat usage rate rises from 30 cents to 33 cents per kWh. At 900 kWh, that line would rise from $270 to $297, a $27 difference before considering any fixed charge, credit or other item. If the whole bill rose by $200, the rate change alone does not explain it.

The household then checks a longer billing period and an old balance included on the front page. Those may explain some or all of the remaining difference. Alternatively, the arithmetic may reveal an unresolved charge to ask about. The point is to reconcile the parts rather than deciding in advance that the retailer or meter must be wrong.

These rates are fictional, not current market offers. Do not use them to judge whether your own tariff is competitive. For a genuine plan comparison, use the applicable official comparison service and current verified offers for your address and usage.

Ask for a bill review with a short, specific question

A useful request identifies the disputed bill, the item you cannot explain and the evidence you checked. For example: “The new bill records 18 kWh a day compared with 10 in the previous period. Please confirm whether the reading is actual, the meter data used and whether an earlier estimate was adjusted.”

Ask for a complaint reference and the expected next step. Keep a brief contact log with dates and outcomes. If the retailer requests evidence, provide it through the approved channel and retain a copy. Avoid sending repeated long accounts that obscure the original question.

Ask separately about affordability if the bill cannot be paid on time. A technically correct bill can still be difficult to manage. A payment arrangement should be clear about amount, frequency, review and any effect on the dispute. Do not agree to a schedule that your own budget cannot support without discussing the difficulty.

Escalate to the right energy dispute service

The Australian Government’s energy-rights directory lists the relevant dispute bodies by state or territory. It recommends contacting the retailer first, then the local independent dispute service if the issue cannot be resolved. The directory is a better route than assuming every jurisdiction has the same organisation name.

Prepare a compact file: the bill, comparison bills, a chronology, the retailer’s answer and the outcome you want. Say whether the issue concerns the amount, meter data, tariff, concession, payment handling or lack of response. Include urgent warnings through the service’s appropriate process.

An ombudsman complaint is not a promise that the bill will be reduced. It is a way to have the issue considered within that service’s role. Keep checking correspondence and do not let the complaint reference become a reason to ignore new information.

Keep the budget and the dispute in separate columns

Record the billed amount, the amount you accept, the amount queried and any agreed payment arrangement. This makes the household’s cash position visible without pretending the disputed amount has disappeared. Update the record after an actual correction or written outcome.

Cognivo’s bill tracker can help with dates and recurring costs. It cannot inspect meter data, compare live tariffs or decide an energy complaint. If you are comparing a replacement offer, use verified inputs and remember that switching providers does not itself resolve a historical bill.

After the issue closes, keep the corrected bill and check the next one. A fixed error should appear in the account records, and an agreed credit needs to be visible. That final reconciliation is more useful than ending the task when someone says the problem should be sorted.

FAQ: Does an estimated bill mean I do not have to pay?

No general conclusion follows from the word “estimated”. Ask the retailer how the estimate was calculated and what review or self-read options apply. Confirm payment requirements and any dispute protections through your local rules. Do not treat an estimate as automatic proof of either a correct amount or an invalid bill.

FAQ: Can I send a photo of my meter?

A retailer may accept a self-read for eligible basic meters. Ask how to submit it, what details are required and when it must be received. Follow safe access instructions and do not touch equipment. Smart-meter accounts can involve a different process, so confirm what applies before trying to reproduce a neighbour’s approach.

FAQ: Should I switch providers before the complaint is finished?

A price comparison and an unresolved bill are separate tasks. Ask what a switch would do to your current account, final bill and any payment arrangement. Keep the historical dispute records. A cheaper future offer does not establish whether the past bill was right, and it does not automatically remove a legitimate outstanding balance.

FAQ: What if I cannot afford the bill even if it is correct?

Tell the retailer promptly and ask about available payment assistance or hardship options. Use your actual household budget to discuss a sustainable amount. If you cannot resolve the difficulty, ask the relevant local energy dispute service about its role. Keep affordability and bill accuracy clear so both issues receive attention.
