How to Pay Your LG&E-KU Bill Online

LG&E-KU's online bill pay portal lets you make one-time payments or set up automatic recurring payments from your bank account or debit card

Louisville Gas and Electric Company and Kentucky Utilities Company (LG&E-KU) operate a combined online payment system where you can pay your electric or gas bill without calling or visiting a payment location. You log in with your account number and create a payment through their website or mobile app. Payments typically post within one to two business days, though the exact timing depends on your bank and the payment method you choose.

The system accepts payments from a checking or savings account (ACH transfer) or from a debit card. Credit card payments are not accepted through LG&E-KU's direct portal, though third-party payment processors may offer that option for an additional fee. You can pay the full balance, a partial amount, or set up automatic payments that recur on a schedule you select.

Key Takeaways

  • You need your LG&E-KU account number and online portal login credentials to make a payment through their website or mobile app.
  • ACH transfers from your bank account typically post within one to two business days and carry no fee.
  • Debit card payments process faster but may carry a convenience fee depending on the payment processor LG&E-KU uses.
  • You can set up automatic recurring payments on a monthly schedule so you do not have to log in each billing cycle.
  • If you do not have online access, LG&E-KU also accepts payments by phone, mail, or at authorized payment locations.

Setting up your LG&E-KU online account

Before you can pay online, you need to create or access an account on LG&E-KU's website. Go to lge-ku.com and look for the login or "My Account" section. If you do not already have an online account, you will need to register using your account number (found on your bill) and personal information such as your name, address, and phone number.

Once registered, you can log in anytime to view your current balance, billing history, and payment options. LG&E-KU also offers a mobile app for iOS and Android devices, which provides the same payment functions as the website. Having an account set up in advance means you can pay quickly when your bill arrives, rather than scrambling to register during a payment important date.

Making a one-time payment online

After logging into your account, navigate to the "Pay Bill" or "Make a Payment" section. You will see your current balance and due date. Enter the amount you want to pay—you can pay in full, pay a partial amount, or pay more than the balance if you want to prepay toward next month's bill.

Select your payment method: ACH transfer from your bank account or debit card. If you choose ACH, provide your routing number and account number. If you choose debit card, enter the card number, expiration date, and CVV. Review the payment details, confirm the posting date (usually one to two business days out), and submit. You will receive a confirmation number when ready; save this for your records.

Understanding ACH transfers versus debit card payments

ACH transfers pull money directly from your checking or savings account and typically carry no fee. The trade-off is timing: ACH payments usually take one to two business days to post to your LG&E-KU account. If your bill is due in two days and you initiate an ACH payment today, it may not post in time to prevent a late fee, depending on your bank's processing speed.

Debit card payments process faster—often the same day or next business day—but LG&E-KU or their payment processor may charge a convenience fee (typically $1 to $3 or a small percentage of the payment amount). Check the fee disclosure before you confirm a debit card payment; the exact amount will be shown on the payment review screen.

If you are paying close to your due date, a debit card payment gives you more certainty that the payment will post on time, even though it costs more. If you have a few days before the due date, ACH is the cheaper option.

Setting up automatic recurring payments

If you want to avoid logging in each month, you can set up automatic payments that deduct from your account on a schedule you choose. In your online account, look for "Autopay," "Automatic Payments," or "Recurring Payments." Select the amount (usually your full bill balance), the payment method (ACH or debit card), and the day of the month you want the payment to occur.

Most customers choose a date shortly after their bill arrives or a few days before the due date. Once set up, the payment will recur each billing cycle unless you cancel it. You can modify or stop automatic payments anytime through your online account, so there is no lock-in period. If your bill amount varies significantly month to month, you may prefer to pay manually each time rather than set a fixed automatic amount.

What to do if your payment does not post on time

If you submitted a payment but it has not appeared in your account after the stated posting time, log back into your account and check the payment status. Most portals show whether a payment is pending, processed, or failed. If the payment failed (for example, due to insufficient funds or an incorrect account number), you will see an error message and can attempt the payment again with corrected information.

If the payment shows as processed but your balance has not updated, wait one additional business day. Bank processing delays can extend the timeline, especially if you paid late on a Friday or holiday. If more than three business days have passed since you submitted the payment and your account still shows the old balance, contact LG&E-KU customer service with your confirmation number to investigate.

Payment options if you cannot pay online

Not everyone has internet access or prefers to pay online. LG&E-KU accepts payments by phone at their customer service number (listed on your bill). You can also mail a check or money order to the address shown on your bill, though mail payments take longer to post and should be sent at least one week before your due date to arrive on time.

Some areas have authorized payment locations—utility offices, grocery stores, or check-cashing services—where you can pay in person with cash, check, or debit card. Call LG&E-KU or check their website to find a location near you. In-person payments usually post the same day or next business day.

Frequently Asked Questions

Can I pay my LG&E-KU bill with a credit card online?

LG&E-KU's direct online portal does not accept credit cards. You can only pay with ACH transfer or debit card through their website or app. Some third-party payment processors may allow credit card payments, but they typically charge a fee for that service.

What happens if I pay after my due date?

A late fee will be added to your next bill if you pay after the due date shown on your statement. The amount varies by your service area. Paying online does not waive the late fee; only paying by the due date prevents it. If you are unable to pay by the due date, contact LG&E-KU to discuss payment arrangements or hardship programs that may be available.

How do I know if my online payment went through?

You will receive a confirmation number when ready after submitting your payment. Log back into your account within one to two business days to verify the payment has posted and your balance has been reduced. You can also check your bank account to confirm the money left your account.

Can I cancel an automatic payment if I need to?

Yes. Log into your account, find the automatic payment settings, and cancel or modify the payment before the next scheduled date. If you cancel after the payment has already been processed, contact LG&E-KU customer service to request a refund or credit to your account.

What if I overpay my bill online?

If you pay more than your current balance, the extra amount becomes a credit on your account and will be applied to your next bill. You can also request a refund of the overpayment by contacting LG&E-KU customer service.
