How we calculate your bill
A closer look at your energy charges |
||
|
On the back of your bill, we've itemised each charge so you can see exactly how we've calculated the total amount owing. The Total is how much you currently owe. It combines any Balance Brought Forward from your previous bill with the new charges from This bill. In the example provided, the customer has an Overdue amount of $578.34 from their last bill and the current bill is $442.08. So, the Total owing is $578.34 + $442.08 = $1020.42 |

How to track your energy use
Start by comparing your usage over time |
||
|
The Consumption Comparison graph on the front of your bill shows your household’s average daily energy use so you can see how it compares to your previous bill and the same period last year – it’s a great way to see how you’re tracking. It includes the average number of kilowatt hours (kWh) you have used each day and your average electricity costs each day. This is based on your average daily use, your tariff and the number of days in this billing period. For a more detailed view, log in to MyAccount. You can view and compare your daily, weekly, monthly and yearly energy use over time and see how you're tracking before your next bill arrives. |
