Term of the Agreement and termination notification requirements

Your Agreement with us starts when you accept our offer (the acceptance date) and continues until you or we end it. We will only start selling you energy under this Agreement after your cooling off period ends and, if we are not already the retailer responsible for the sale of energy at the Premises, once the transfer to us is complete.

Any benefits (such as credits) will apply for the duration set out in the Energy Plan. We will notify you of your options before this period ends.

You must notify us at least 4 business days before moving out of the Premises. If you move out and we can read your meter, the Agreement will end after we take the reading.

Billing and payment arrangements

For electricity customers, if you have a smart meter, Sumo bills monthly. If you have a basic meter or manually read interval meter, Sumo offers products that are billed every three months. Some existing Sumo customers with a basic meter or manually read interval meter may continue to be billed monthly based on estimates of usage.

We bill Victorian gas customers every two months, and NSW gas customers quarterly.

The amount you pay for energy will include usage charges (which vary depending on how much energy you use) and a daily supply charge. The initial prices are set out in the Important Details section of the Agreement.

In certain circumstances, we may also charge other fees. These fees are also set out in the Important Details.

We may vary your energy prices or impose additional charges in accordance with the Terms and Conditions. We will give you 5 business  days’ notice if we do (or 10 business days if you are in Queensland). Your prices, and variations to them, are specific to you. They may be different to prices we charge other customers.

Payment options will be detailed on your bill, and include BPAY, direct debit, MasterCard, VISA and AMEX.

Concessions and rebates (only applicable to residential customers)

If you are a residential customer and hold a valid Government concession card, you may be eligible for a rebate on your energy bills. More information about concessions is available at

Electronic transactions

We will send bills and other notices to you by email (and you will be recognised as having received them) if you agreed for us to do so. If you haven’t already, we encourage you to arrange to receive bills and notices from us by email. Just contact us on 03 9102 8400
