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

We bill monthly for electricity, and every two months for gas.

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 notify you in writing if we do, by no later than your next bill. 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 13 88 60 or
