You can pay an LG&E bill as a guest by visiting their payment portal, entering your account number and ZIP code, and completing the transaction without signing up

LG&E (Louisville Gas and Electric Company) and KU (Kansas City Power and Light) allow one-time payments through their guest checkout option. You do not need to create a username or password. The process takes about five minutes and works for both electric and gas bills.

Guest payment is useful if you pay infrequently, want to avoid storing payment information online, or prefer not to manage another login. The trade-off is that you cannot set up automatic payments or view your payment history through the portal — each payment is separate.

Key Takeaways

  • Guest payment requires your account number (found on your bill) and the ZIP code associated with your account.
  • You can pay by debit card, credit card, or bank account transfer, though fees vary by method.
  • The payment processes immediately, but it may take one to two business days to appear on your account.
  • Guest payments do not set up recurring billing — you must return to the portal each time you want to pay.
  • If you lose your bill, you can still pay by calling LG&E customer service at 502-589-1444 (Louisville area) or 816-654-3210 (Kansas City area).

Steps to Pay as a Guest Online

Start by going to the LG&E payment portal. The exact URL depends on your location: Louisville customers use one portal, Kansas City customers use another. If you are unsure which one applies to you, check your bill — it will list your service area.

Once you reach the portal, look for a link or button labeled "Pay as Guest" or "Guest Payment." Click it. You will be asked for your account number and the ZIP code on file. Your account number appears on the front of your bill, usually near the top. Enter both pieces of information exactly as they appear.

The system will pull up your account and show your current balance. Review the amount to make sure it matches your bill. Then select your payment method: credit card, debit card, or bank account. Enter the payment amount (you can pay the full balance or a partial amount) and proceed to checkout.

After you submit the payment, you will receive a confirmation number on screen. Write it down or take a screenshot. The transaction is complete, but the payment may not show as posted on your account for one to two business days.

Payment Methods and Fees

LG&E accepts three payment methods for guest transactions. Credit and debit cards carry a convenience fee, usually between 2 and 3 percent of the payment amount — the exact percentage is shown before you confirm. Bank account transfers (ACH) typically have no fee or a flat fee of around $1, depending on your bank.

If the fee matters to you, bank account transfer is the cheapest option. You will need your routing number and account number, which you can find at the bottom of a check or by logging into your bank's website. The payment takes the same one to two business days to post.

Do not use a guest payment if you are trying to dispute a charge or need to set up a payment plan — those require you to contact customer service directly or create an account.

What Happens After You Pay

Your confirmation number proves the payment was submitted. Keep it for your records. The money leaves your bank account or card immediately, but LG&E's system may not show it as posted for one to two business days.

If you do not see the payment reflected on your account after two business days, call customer service. Have your confirmation number ready. They can look up the transaction and tell you the status.

Guest payments do not generate a receipt in your online account history because you have no account login. If you need proof of payment later, your confirmation number and your bank or credit card statement are your evidence.

When to Create an Account Instead

Guest payment works for occasional, one-time payments. If you pay your bill every month, creating a free account saves time and eliminates the need to enter your account number repeatedly. An account also lets you set up automatic payments, view your bill history, and report outages online.

To create an account, go to the same payment portal and select "Create Account" or "Sign Up." You will need your account number, ZIP code, and an email address. The account is free and takes about five minutes to set up.

If you already have an account but forgot your password, use the "Forgot Password" link on the login page. You will receive a reset link by email.

Troubleshooting Common Issues

If the system says your account number or ZIP code is incorrect, double-check both against your bill. Account numbers can be long and include letters or dashes — make sure you are entering them exactly. If your ZIP code does not match what is on file, your account may be registered to a different address (for example, a business office or a previous address).

If you cannot find the guest payment option, you may be on the wrong portal. Louisville and Kansas City have separate systems. Check your bill to confirm your service area, then search for "[Your City] LG&E payment" to find the correct link.

If your payment is rejected, the most common reasons are an incorrect card number, an expired card, or insufficient funds in your bank account. Try again with a different payment method, or call customer service to pay over the phone.

Paying by Phone or Mail if Online Does Not Work

If you cannot pay online, you have two other options. Call LG&E customer service at 502-589-1444 (Louisville) or 816-654-3210 (Kansas City) and provide your account number and payment method. A representative will process the payment over the phone. This method also works if you do not have internet access.

You can also mail a check to the address on your bill. Write your account number on the check and mail it to the address listed under "Payment" or "Make Checks Payable To." Mailed payments take longer to process — typically five to seven business days — so plan ahead if your due date is soon.

Frequently Asked Questions

Do I need to create an account to pay my LG&E bill online?

No. The guest payment option lets you pay without signing up. However, if you pay regularly, an account saves time and lets you set up automatic payments.

What if I do not have my bill and do not know my account number?

Call customer service with your name and service address. They will look up your account number and can process a payment over the phone or give you the number so you can pay online as a guest.

Is there a fee for paying online as a guest?

Credit and debit card payments carry a convenience fee of 2 to 3 percent. Bank account transfers usually have no fee or a small flat fee. Paying by phone or mail has no fee.

How long does it take for my payment to show up on my account?

One to two business days. Your confirmation number is proof the payment was submitted. If it does not appear after two business days, contact customer service with your confirmation number.

Can I set up automatic payments as a guest?

No. Automatic payments require you to create an account. Guest payments are one-time only — you must return to the portal each time you want to pay.
