If you have a smart electricity meter that’s remotely read, we use real usage data to work out your monthly bill.
For customers with a basic meter that's read every two to three months, we don’t have actual data to use each month. Instead, we estimate your energy usage on a variety of factors including your historical usage and seasonal activity, then bill you on that figure. When an actual meter reading is completed, we adjust your account as needed. Customers new to AGL won't have historical data so estimates are based on averages of similar customers over the time period.
If you have a basic meter and would like to avoid estimated bills, you can submit your own meter reading in My Account.
