Knox Energy payment methods and where to send your money
Knox Energy operates in parts of Australia and lets you pay your bill through several channels: online via their website, by phone, by mail, or in person at a post office or authorised payment location. The fastest and most direct method is online through your Knox Energy account, where you can pay immediately with a debit or credit card. If you prefer not to use the internet, you can call their customer service line to pay by phone with a card, or mail a cheque to the address printed on your bill.
Your bill itself shows the due date and the amount owing. This date is when Knox Energy expects payment, though you can pay early without penalty. If you miss the due date, Knox Energy will typically send a reminder notice before taking further action. Paying on time keeps your account in good standing and avoids late fees or disconnection risk.

Paying online through your Knox Energy account
Log into your Knox Energy online account using your customer number and password. If you do not have an online account yet, you can create one on their website — you will need your bill or customer number to set it up. Once logged in, look for a "Pay Now" or "Make a Payment" button, which is usually on your account dashboard or bill page.
Enter the amount you want to pay and choose your payment method: debit card, credit card, or bank transfer if that option is available. Review the details, confirm the payment, and Knox Energy will process it. You should receive a confirmation number or receipt immediately. The payment typically appears in your account within one business day, though some banks may take longer to clear the transaction on their end.
Paying by phone
Call Knox Energy's customer service number, which is on your bill. Have your bill or customer number ready, along with your payment method — a debit card, credit card, or bank account details if they accept bank transfers over the phone. A customer service representative will take your payment details and process the payment while you are on the call.
Phone payments are useful if you do not have internet access or prefer to speak to someone. The payment is processed immediately, though it may take a business day to show in your account. Ask for a confirmation number before you hang up so you have a record of the transaction.
Paying by mail
Write a cheque payable to Knox Energy and include your customer number on the back of the cheque. Mail it to the address shown on your bill — this is usually a locked post office box or a payment processing centre. Include your bill or a copy of it so Knox Energy can match the payment to your account.
Cheques take time to clear: allow at least five to seven business days for the cheque to arrive, be processed, and appear in your account. If your due date is soon, mail is not the best option. Always keep a copy of your bill or write down the cheque number so you can track the payment if needed.
Paying at a post office or authorised location
Knox Energy may accept payments at Australia Post outlets or other authorised payment agents. Bring your bill or customer number and the cash or card you want to use. The staff member will process your payment and give you a receipt. Ask them how long it takes for the payment to reach Knox Energy — this varies depending on the location and the payment method.
In-person payment is useful if you prefer to handle money face-to-face or do not have a bank account or internet access. Keep your receipt as proof of payment until the amount appears in your Knox Energy account.
What to do if you cannot pay by the due date
Contact Knox Energy before the due date if you know you cannot pay the full amount. Explain your situation — they may be able to set up a payment plan, extend the due date, or discuss other options. Many energy providers have hardship programs for customers facing financial difficulty, and Knox Energy may offer one as well.
Waiting until after the due date to contact them makes the situation harder. A late payment can trigger a reminder notice, late fees, or a disconnection warning. Acting early gives you more options and shows Knox Energy you are trying to manage the bill responsibly.
Understanding payment confirmation and your account
After you pay, Knox Energy sends a confirmation — either by email, SMS, or mail depending on how you paid and what contact details they have on file. Keep this confirmation until the payment shows in your account. If you paid online or by phone, the confirmation usually arrives within minutes. If you paid by mail or at a post office, it may take several days.
Log into your online account a few days after paying to confirm the payment has been recorded. Your account should show the payment date, the amount, and your new balance. If the payment does not appear after a week, contact Knox Energy with your confirmation number or receipt to check on it.
Frequently Asked Questions
Can I set up automatic payments with Knox Energy?
Many energy providers offer automatic payment options where the bill amount is deducted from your bank account on a set date each month. Check your online account or contact Knox Energy to see if this option is available and how to set it up. Automatic payments reduce the risk of missing a due date.
What happens if I pay more than I owe?
If you overpay, Knox Energy will credit the extra amount to your next bill. You can also request a refund of the overpayment, though this may take a few weeks to process. Contact them with your account number to arrange a refund if you prefer not to carry a credit balance.
Is there a fee for paying by credit card?
Some energy providers charge a processing fee when you pay by credit card, while others do not. Check your bill or Knox Energy's website to see if a fee applies. If a fee is listed, paying by debit card, bank transfer, or cheque may be cheaper.
Can I pay someone else's Knox Energy bill?
Yes, you can pay another person's bill if you have their customer number and the amount owing. Pay online using their customer number, or call and provide their details. The payment will be credited to their account. You do not need to be the account holder to make a payment.
What should I do if my payment was rejected?
If your online or phone payment was declined, check that your card details are correct and that your card has not expired. Ensure you have sufficient funds available. If the problem persists, try a different payment method or contact your bank to check if there are any blocks on the card. Then contact Knox Energy if you need help.
