Billing & payments
Direct Debit is the set and forget way to keep on top of your bill payments:
- Pay your bill in full whenever it’s due
The total amount due will be automatically deducted from your credit or debit card or bank account on the payment due date. - Make smaller, regular payments along the way - so it's easier to budget for your energy costs
You get to choose the day, how much and how often. Chip away at your bill every week, fortnight or month. It's easier to align to your pay cycle or budget because you can choose the day to deduct the payment from your account.
If you need a little more time to pay your bill - you may be eligible for a payment extension. Select the ‘More time to pay’ button to see what payment extensions or arrangements that could be available to you.
To update an existing direct debit, including your bank account or credit card details, you will need to cancel your existing direct debit arrangement and set up a new one using the Direct Debit online form.
Outages
If everything looks ok, check the outage finder in MyAccount for updates on the latest planned and unplanned outages and when we expect to restore power. Select the ‘Outages affecting my property’ option to filter the outages relevant to you.
Please call our 24/7 hotline on 13 23 51 to report all faults and outages.
Unless it’s an emergency, we'll let you know at least three days before a planned power interruption.
Prepaid meters
To access the payment form, you can either log in to MyAccount or use the pay online form on our website.
Usage
See when you're using energy the most across the day, week, month and billing period. See how you're energy costs are tracking between bills so you know what to expect when it arrives.
We've also included some simple insights to help you get a better idea of when you're using energy the most.
Usage
If you have linked accounts, each of your meters will display together on the aggregated usage graph.
You can download up to 365 days of your usage data using the Interval data form.
We then use your current usage behaviour to predict what your next bill is likely to be. The estimated next bill is an estimate only and will become increasingly accurate as the end of the billing period approaches. Where applicable, this calculation includes solar buyback credits, concessions or rebates applied to your account and any outstanding debts.
Please note: The figure shown can vary due to factors such as actual usage and the proportion of the bill that is based on a fixed vs variable charge e.g., smaller bills will have a bigger proportional fixed charge. All amounts shown are inclusive of GST.
