How billing works

Sometimes we need to estimate your energy usage rather than bill you on actual data. This could be because:

• the meter reader couldn't access your meter (maybe because of a locked gate, an overgrown shrub or a pet guarding your property)

• you're on monthly billing with a basic meter

• your meter is broken or faulty.

Find out more about Estimated bills.

To avoid receiving estimated bills, you should always make sure there's safe and unhindered access to your meter. You can also submit your own meter reading in the AGL app or in My Account.

A billing period can be one, two or three months.

We generate and send your bill to you on the same date each month. For example, if your billing date is on the 15th, we’ll always generate and send your bill on the 15th of the month.

Monthly billing for smaller bills

You can choose to get monthly bills to break bills into smaller payments and make budgeting easier.

If you have a smart electricity meter, we use real usage data to work out your monthly bill. For basic meter customers on monthly billing, up to two out of every three bills can be from an estimate of your usage, based on your usage history and seasonal data. When we receive an actual reading, we adjust your account.

1. To set up monthly billing in My Account:
2. Log in to My Account:
3. Select your name in the top right corner, then Account Settings.
4. In the Billing and payments menu, go to Monthly billing and select Edit.
5. Select your account, then choose your preferred bill issue date.
6. Select Switch to monthly billing to finish.

A tariff is how you’re charged for your electricity usage. There are different tariff types, and you may be on one or a combination of the following:

• Single rate - You’re charged at the same rate for the electricity you use no matter what time of day.
• Time of use - You’re charged different rates depending on the time of day. Peak times are when electricity is in high demand, off-peak times are periods of lower demand, and shoulder rates are between peak and off-peak. You can find your specific tariff times in your bill under New charges and credits, and Usage and supply charges.
• Controlled load - You may be charged for electricity supplied to a specific appliance, such as an electric hot water system, at a different rate to your other electricity usage.
• Demand - Demand charges are based on the load you place on the electricity network when there’s high customer demand. The most common demand charges involve measuring your usage over 30-minute intervals during a demand time period (for example, 5 to 9 pm). The highest usage measure for the billing month is used to calculate your demand charge for the entire month.

Your bill projection in My Account and the AGL app helps you understand the future costs of your next bill.

It's an estimate of what your bill will be at the end of your billing period. It’s based on your electricity or gas usage for the same period last year.

If you’ve recently joined AGL, you’ll only get bill projections if you have a digital meter. Your bill projection will be based on your most recent bill or the average of similar households in your state.

If you have a basic meter, you can improve the accuracy of your bill projection by submitting a meter read.

You can also keep an eye on your cost to date in My Account, or the AGL app. This will tell you the estimated cost from your last bill up until today.

Find out more about how we calculate bill projection and cost to date by visiting Usage calculations.

Meters are usually located in a common area such as a hallway cupboard, garage, basement, or behind a ceiling or wall access panel in the foyer or corridor. In some cases, the builder may have installed the meter in your apartment under the sink in the bathroom or behind a hidden access panel in the wall.

On most hot water meters, you’ll see a series of numbers. The black numbers measure whole units and the red numbers measure decimals.

By reading the meter at two different points in time (such as at the beginning of the day and at the end) you can determine what your water usage is for that amount of time. Learn more about How to read your meter.
