LG&E and KU's online payment portal is at lge-ku.com, where you can pay your electric or gas bill immediately using a bank account or debit card
The fastest way to pay is through the LG&E and KU website itself. Go to lge-ku.com, select "Pay My Bill," and you'll be asked to enter your account number (found on your paper bill or in any previous online statement) and your ZIP code. From there you can choose to pay once, set up a recurring payment, or both.
Payment goes through instantly if you use a debit card or checking account. There's no fee for paying from a bank account, but debit card payments may carry a small charge depending on the payment processor LG&E and KU uses that day. The site will show you any fee before you confirm the payment, so you'll know the exact total before your money leaves.
Key Takeaways
- Pay online at lge-ku.com by entering your account number and ZIP code, then choosing your payment method.
- Bank account payments have no fee; debit card payments may charge a small processing fee shown before you confirm.
- You can set up a one-time payment or recurring automatic payments on the same screen.
- If you don't have your account number, you can look it up on lge-ku.com using your service address and last name.
- Payment confirmation appears immediately, and you can save or print your receipt for your records.
What information you need before you start
Have your account number ready. It's a 10-digit number printed on your bill in the upper right corner, or you can find it in your online account if you've already created one at lge-ku.com. If you don't have your bill handy, you can look up your account number on the LG&E and KU website by entering your service address and the last name on the account.
You'll also need your ZIP code and your payment method. LG&E and KU accepts checking or savings account information (you'll need your routing number and account number) or a debit card (Visa, Mastercard, American Express, or Discover). Credit cards are not accepted for bill payment on the main website, though some third-party payment services may offer that option.
Setting up automatic payments so you never miss a due date
The same payment screen where you make a one-time payment also lets you set up recurring automatic payments. After you enter your account number and payment method, look for the option to "Set Up Automatic Payments" or "Recurring Payment." You'll choose how much to pay (the full bill amount, a fixed dollar amount, or a minimum payment) and which day of the month the payment should go through.
Most people choose the full bill amount on the due date shown on their bill, which means you'll never carry a balance or face a late fee. You can change or cancel automatic payments anytime by logging into your account at lge-ku.com or by calling LG&E and KU customer service. If you set up automatic payments and then want to pay extra one month, you can still make an additional one-time payment without affecting your recurring schedule.
Creating an online account to track payments and usage
You don't need an online account to pay your bill once, but creating one at lge-ku.com makes it easier to manage payments over time. Click "Create Account" or "Sign Up," then enter your account number, service address, and email. LG&E and KU will send you a confirmation email with a link to set your password.
Once you're logged in, you can see your current bill, payment history, and estimated usage for the month. You can also set up automatic payments, change your payment method, and view your bill in PDF form. If you have multiple accounts (for example, a home and a rental property), you can add all of them to one login and switch between them.
Other ways to pay if you prefer not to use the website
LG&E and KU also accepts payment by phone at 502-589-1444 (Louisville area) or 913-881-5900 (Kansas area). You'll need your account number and payment method, and the process takes about five minutes. Phone payments are processed the same way as online payments — instantly if you use a bank account, with a possible small fee for debit cards.
You can also mail a check to the address on your bill, though mail typically takes 7 to 10 days to arrive and be processed. If your due date is coming up soon, mailing a check risks a late payment. In-person payment at LG&E and KU offices or authorized payment locations is another option; check lge-ku.com for locations near you.
What to do if your payment doesn't go through
If your payment is declined, the website will tell you why — usually because the account number doesn't match the payment method, the bank account or card has insufficient funds, or the card has expired. Fix the problem and try again immediately. Your bill won't be marked late until after the due date has passed, so you have time to correct the issue.
If you've already made a payment and want to confirm it went through, log into your account at lge-ku.com and check your payment history. You should see the payment listed with the date it was processed. If you made a payment by phone or mail and it's not showing up after three business days, call LG&E and KU customer service to confirm they received it.
Avoiding common mistakes when paying online
The most common error is entering the wrong account number. Double-check the 10-digit number on your bill before you submit payment. If you enter an incorrect number, your payment may go to the wrong account or be rejected entirely.
Another mistake is setting up automatic payments and then forgetting about them, which can lead to overpayment if your usage drops or if you move. Review your automatic payment settings every few months and adjust the amount if needed. If you're moving, contact LG&E and KU before your move date so they can close your old account and open a new one — paying the old account after you've moved won't help you.
Finally, don't assume a payment is complete just because the website doesn't show an error message. Wait for the confirmation screen and, if possible, save or print your receipt. The confirmation will include a transaction number you can reference if you ever need to dispute the payment.
Frequently Asked Questions
Is there a fee to pay my bill online at lge-ku.com?
No fee applies if you pay from a checking or savings account. Debit card payments may include a small processing fee, which LG&E and KU shows you before you confirm the payment. The exact fee varies but is typically a few dollars.
How long does it take for my online payment to show up on my account?
Online payments process instantly, and you'll see a confirmation number right away. The payment should appear in your account history within one business day. If you're paying close to your due date, confirm the payment went through before assuming your bill is paid.
Can I pay someone else's LG&E and KU bill online?
You can pay any account if you have the account number and ZIP code, but the payment will be applied to that account only. If you're paying a family member's bill, make sure you have the correct account number so the payment doesn't go to the wrong person.
What should I do if I set up automatic payments but want to skip one month?
Log into your account at lge-ku.com, go to your automatic payment settings, and pause or cancel the payment for that month. You can resume automatic payments the following month, or you can make a one-time manual payment instead if you prefer.
Can I pay my LG&E and KU bill with a credit card online?
The main LG&E and KU website does not accept credit cards for bill payment. You can use a debit card, checking account, or savings account. Some third-party payment services may offer credit card payment as an option, but they typically charge a higher fee.
