LG&E and KU's online bill payment system lets you pay from your computer or phone without mailing a check or calling a representative

Louisville Gas and Electric Company (LG&E) and Kentucky Utilities Company (KU) operate a shared online payment portal where you can view your bill, set up automatic payments, and pay one time. The system is free to use. You can pay with a bank account (electronic check) or a debit or credit card, though card payments may carry a small fee.

The portal is called My Account, and you reach it through the LG&E and KU website. You will need your account number (printed on your bill) and a password you create when you register. Once you log in, you can see your current balance, payment history, and usage details for the past 12 months.

Key Takeaways

  • Register for My Account on the LG&E and KU website using your account number and a new password you choose.
  • You can make a one-time payment or set up automatic monthly payments from a bank account at no charge.
  • Credit and debit card payments work but may include a processing fee that varies by card type.
  • Payments made before 5 p.m. on the due date typically post the same day; payments after that time post the next business day.

How to register for My Account

Go to the LG&E and KU website and look for the My Account login link, usually near the top of the page. Click "Register" or "New User" and enter your account number. You will find this on your paper bill or in any email the company sends you.

Create a password at least 8 characters long that includes uppercase and lowercase letters, a number, and a special character (like ! or #). Write it down or use a password manager so you do not forget it. The system will ask for your email address and phone number. Use contact information you check regularly, because LG&E and KU will send payment confirmations and account alerts to these addresses.

Once you finish registering, you can log in immediately. The first time you log in, the system may ask you to verify your identity by answering security questions or confirming recent charges on your account. This step takes a few minutes and happens only once.

Making a one-time payment

Log into My Account and look for a button or link that says "Make a Payment" or "Pay Now." The system will show your current balance and due date. Enter the amount you want to pay (you can pay the full balance or a partial amount) and choose your payment method.

If you pay by bank account, you will enter your routing number and account number. Payments from a checking or savings account are free and usually post within one business day. If you pay by debit or credit card, the company charges a processing fee that depends on the card type — typically 2 to 3 percent of the payment amount. The system will show you the exact fee before you confirm.

After you submit the payment, the system gives you a confirmation number. Save this number or take a screenshot. LG&E and KU will also email a receipt to the address you registered with. If you do not see the email within a few hours, check your spam folder.

Setting up automatic monthly payments

Automatic payments remove the risk of missing a due date. In My Account, look for "Autopay," "Automatic Payment," or "Recurring Payment." Choose the date you want the payment to come out each month — most people pick the due date shown on their bill, but you can choose any date between the 1st and the 28th.

You can set up autopay only from a bank account, not from a card. Enter your routing and account number. The system will deduct the full bill amount on the date you choose each month. If your bill varies (which it usually does, especially if you use more gas or electricity in winter), the payment amount will change automatically.

You can change or cancel autopay at any time by logging back into My Account. There is no penalty for stopping it. If you want to pause autopay for one month, you can do that too — just log in and skip that month's automatic deduction.

Understanding payment timing and posting

Payments made before 5 p.m. Eastern Time on a business day usually post to your account the same day. Payments made after 5 p.m. or on a weekend or holiday post the next business day. LG&E and KU considers a payment posted when it reaches their system, not when you submit it online.

If your bill is due on a specific date and you are cutting it close, pay at least one business day before the due date to be safe. If you miss the due date, LG&E and KU may charge a late fee. The amount varies but is typically a percentage of your bill. You can still pay online after the due date — the late fee will be added to your next bill.

Troubleshooting common payment problems

If your payment is rejected, the most common reason is a mismatch between the account number you entered and the one on file, or a bank account number that is incorrect. Check your bill to confirm your account number and double-check your routing and account numbers with your bank before trying again.

If you see a payment in My Account but it has not posted to your bank account yet, wait one to two business days. Bank transfers take time to clear, especially if you paid late in the day or on a weekend. If more than two business days have passed and the money is still missing, contact your bank first — they can trace the transaction faster than LG&E and KU can.

If you forget your password, click "Forgot Password" on the login page. The system will send a reset link to your email. If you do not receive the email, check your spam folder or try registering again with a different email address. If you cannot access My Account at all, you can always call LG&E and KU's customer service line to make a payment by phone.

When to contact customer service instead

Most payment issues can be solved online, but some situations require a phone call. If you have questions about your bill amount, want to report a billing error, or need to discuss a payment plan because you cannot pay the full amount, call LG&E and KU directly. Their representatives can see your full account history and work with you on options.

If your account is in your landlord's name but you pay the bill, or if you are trying to set up a payment for someone else's account, you will need to speak with customer service. They can add you as an authorized user so you can pay online without needing the account holder's password.

Frequently Asked Questions

Is there a fee to pay my bill online?

Paying from a bank account is free. Paying with a debit or credit card includes a processing fee of roughly 2 to 3 percent, which the system shows you before you confirm the payment. The fee is added to your payment amount, not charged separately.

Can I pay my bill if I do not have a bank account?

Yes. You can use a debit card or credit card to pay online. The card payment will include a processing fee. If you do not have a card either, you can pay by phone or mail, though those methods take longer than online payment.

What happens if I set up autopay and then move?

Autopay will continue to your old account until you close it. When you move, contact LG&E and KU to open a new account at your new address. You will need to set up autopay again with your new account number. The company can help you transfer your autopay settings during the move process.

Can I pay my bill early?

Yes. You can pay any amount at any time through My Account. Paying early reduces the balance owed and can lower the amount of interest charged if your account carries a past-due balance, though LG&E and KU does not charge interest on residential bills — only late fees.

How do I know if my payment went through?

The system shows a confirmation number immediately after you submit payment. LG&E and KU also emails a receipt. You can log back into My Account anytime to see your payment history and current balance. If a payment does not appear within two business days, contact customer service.
