Ameren UE offers three main ways to pay your electric and gas bill: online through their website, by phone, or by mailing a check

Ameren UE is the electric and gas utility serving central and southern Illinois. You can pay your bill the same day you receive it or wait until the due date printed on your statement — the method you choose depends on what works best for your schedule and how quickly you want the payment processed.

The fastest way is online through Ameren UE's website or mobile app, where payment posts within one business day. Phone payment is also same-day if you call before their cutoff time. Mailing a check takes longer — typically 7 to 10 business days — so plan ahead if you use that method.

Key Takeaways

  • Online payment through the Ameren UE website or app is the fastest method and posts within one business day.
  • Phone payment is available by calling Ameren UE's customer service line, and you can pay with a debit or credit card the same day you call.
  • Mailing a check requires 7 to 10 business days to process, so send it at least two weeks before your due date to avoid a late payment.
  • You can set up automatic recurring payments through your bank or Ameren UE's website so you never miss a due date.
  • Ameren UE does not charge a fee for online or phone payments made with a bank account, but credit card payments may carry a processing fee.

Paying online through the Ameren UE website or app

Log into your account on the Ameren UE website (ameren.com) or read the Ameren mobile app on your phone. Enter your account number and password, then select the "Pay My Bill" or "Make a Payment" option. You will see your current balance and due date.

Choose your payment method: bank account (no fee) or debit or credit card (a processing fee applies). Enter the amount you want to pay — you can pay the full balance, a partial amount, or set a one-time payment for a future date. Review the details and confirm. Your payment posts within one business day.

If you do not have an online account yet, you can create one on the Ameren UE website using your account number and service address. You will receive a confirmation email once your account is set up.

Paying by phone

Call Ameren UE's customer service line at 1-800-755-5000. A representative will ask for your account number and the amount you want to pay. You can pay with a debit card, credit card, or bank account information.

Phone payments are processed the same day you call, as long as you call before the cutoff time (usually 5 p.m. central time on business days). If you call after hours or on a weekend, your payment will be processed the next business day. There is no fee for paying with a bank account, but credit card payments may include a processing fee.

Paying by mail

Write a check or money order payable to Ameren UE and include your account number on the check. Mail it to the address printed on your bill — this address is specific to your region and ensures your payment reaches the right processing center.

Mail payments typically take 7 to 10 business days to process after Ameren UE receives them. The postal service itself can add 3 to 5 days depending on where you live. To avoid a late payment, mail your check at least two weeks before your due date. Keep a copy of your check or note the check number for your records.

Setting up automatic payments

Automatic payments remove the risk of forgetting a due date. You can set them up through Ameren UE's website or by calling customer service. Choose whether you want the full balance paid automatically each month or a fixed amount.

Ameren UE will deduct the payment from your bank account on or shortly after your due date each month. You can change or cancel automatic payments anytime through your online account or by calling customer service. If your bill amount changes significantly, you may want to adjust your automatic payment to match.

Payment fees and what they cover

Ameren UE does not charge a fee when you pay with a bank account (checking or savings) online or by phone. Credit card and debit card payments include a processing fee set by the payment processor, not by Ameren UE. The fee is usually 2 to 3 percent of your payment amount and is added to your bill or deducted from your payment.

Mailed checks and money orders have no fee. If you pay in person at an Ameren UE office or authorized payment location, there is no fee for cash or check payments, but some locations may charge a fee for credit card payments.

What to do if your payment is late

If your payment does not arrive by the due date, Ameren UE may charge a late fee and report the late payment to your credit history. Contact Ameren UE when ready if you know your payment will be late — they may be able to work out a payment plan or delay reporting the late payment while they investigate.

If you are struggling to pay your bill, Ameren UE offers budget billing (which spreads your annual costs into equal monthly payments) and information programs for customers with low income. Call customer service to learn about these options.
