The fastest way to pay LG&E is online through their website or mobile app, which processes payments the same day you submit them
LG&E (Louisville Gas and Electric Company) and KU (Kansas City Power and Light) let you pay through multiple channels. Online payment through their website or the LG&E mobile app is the quickest option — your payment posts immediately, and you get a confirmation number right away. You can also pay by phone, mail, or in person at a payment location. The method you choose depends on how quickly you need the payment to reach them and whether you want a paper record.
Your bill shows a due date, not a payment deadline. If you pay after the due date, LG&E may charge a late fee. The amount varies, but you can see it listed on your bill. Payments made online or by phone typically post within one business day; payments by mail take longer depending on postal delivery time.
Key Takeaways
- Online payment through LG&E's website or mobile app posts the same day and requires your account number and a bank account or debit card.
- Phone payments go through an automated system or a representative and cost the same as online payment with no additional fee.
- Mail payments take 7 to 10 business days to arrive and post, so send them at least two weeks before your due date to avoid a late fee.
- In-person payment at a payment center or authorized retailer (like a grocery store) posts the next business day and requires no online access.
- Setting up automatic payments through your bank account removes the risk of forgetting and typically costs nothing.
Paying online through the LG&E website or app
Go to lge-ku.com and log into your account using your account number and password. If you do not have an online account, you can create one by entering your account number and the zip code associated with your service address. Once logged in, select "Pay My Bill" or a similar option in the menu.
You will be asked to choose a payment amount and a payment method. LG&E accepts bank account transfers (which cost nothing) and debit or credit cards (which may carry a processing fee — the website will show the fee before you confirm). Enter the payment date you want (same day or a future date), review the details, and submit. You will receive a confirmation number immediately. Save or print this number in case you need to reference the payment later.
The LG&E mobile app works the same way. Download it from the Apple App Store or Google Play, log in with your account credentials, and follow the same steps. Mobile payments post just as quickly as website payments.
Paying by phone
Call LG&E's automated payment line at 1-800-331-7661. You will need your account number and a bank account or debit card ready. The system will walk you through entering the payment amount, the date you want to pay, and your payment method. You will receive a confirmation number at the end of the call.
If you prefer to speak with a representative, you can also call the same number and ask to be transferred. A representative can answer questions about your account or payment options, though the process takes longer. The phone line is available 24 hours a day, 7 days a week.
Paying by mail
Write a check or money order payable to LG&E. Include your account number on the check. Mail it to the address printed on your bill — this address is different depending on whether you are an LG&E or KU customer, so always use the address on your specific bill.
Mail payments typically take 7 to 10 business days to arrive and post to your account. To avoid a late fee, mail your payment at least two weeks before the due date. If you are close to the due date, use online or phone payment instead. Keep a copy of the check or the envelope for your records.
Paying in person at a payment location
LG&E has payment centers in Louisville and surrounding areas where you can pay in cash, check, or debit card. You can also pay at authorized retailers like grocery stores or convenience stores that accept utility bill payments. Bring your bill or account number with you.
In-person payments typically post the next business day. Call LG&E at 1-502-627-2700 (for LG&E customers) or 1-816-654-3100 (for KU customers) to find a payment location near you, or check their website for a list of authorized retailers in your area.
Setting up automatic payments from your bank account
Automatic payments remove the risk of missing a due date. You can set this up through LG&E's website by logging into your account, going to "Billing and Payment," and selecting "Autopay" or "Automatic Payment." Choose the amount (your full bill or a fixed amount), the date each month you want it to come out, and your bank account. LG&E will deduct the payment automatically on that date each month.
You can change or cancel automatic payments anytime through your online account. If your bill amount varies significantly month to month, you can set the payment to a fixed amount and pay any remaining balance manually, or you can update the automatic amount each month before the payment date.
What to do if your payment does not post
If you paid online or by phone and do not see the payment on your account within one business day, log back into your account and check the payment history. Look for your confirmation number and the status of the payment. If the status shows "pending," wait another business day.
If the payment shows as completed but your account balance has not changed, contact LG&E customer service at 1-502-627-2700 (LG&E) or 1-816-654-3100 (KU) with your confirmation number. They can trace the payment and confirm when it will post. If you paid by mail and it has been more than 10 business days, call to report it so they can investigate.

How do I know if my payment went through?
