The fastest way to pay ComEd is through their website or mobile app, where you can set up a one-time payment or enroll in autopay

ComEd's website at ComEd.com is the quickest route. Log into your account, select "Pay My Bill," and choose your payment method — debit card, credit card, or bank account. You'll see your balance and due date before you confirm. Payment posts within one business day for bank transfers and usually the same day for cards.

If you prefer not to log in each time, autopay removes the step entirely. You authorize ComEd to withdraw the amount due on your due date from a bank account or card you choose. You can change or cancel autopay anytime through your account settings. Many people use this to avoid late fees, since the payment happens automatically.

The ComEd mobile app (available on iOS and Android) works the same way as the website. You can pay, view your bill, check your usage, and manage autopay from your phone.

Key Takeaways

  • ComEd's website and mobile app let you pay immediately with a debit card, credit card, or bank account transfer, with no fees added by ComEd.
  • Autopay withdraws your bill amount automatically on the due date, which prevents late fees and removes the need to remember to pay each month.
  • Phone and mail payments are slower — phone takes one to two business days, and mail can take up to two weeks depending on postal delivery.
  • Late fees apply if payment is not received by the due date shown on your bill, regardless of when you send it.
  • If you cannot pay the full amount, contact ComEd before the due date to discuss payment plans or hardship programs in your area.

Paying by phone or through the mail

If you do not have internet access or prefer to speak with someone, you can pay by phone at 1-877-426-6331. Have your account number and payment method ready. A representative will process your payment over the phone using a debit card, credit card, or bank account. This method takes one to two business days to post to your account.

Mailing a check or money order is an option, but it is the slowest method. Address your payment to the address shown on your bill under "Payment Address" — this is different from your service address. Include your account number on the check or money order. Mail can take one to two weeks to arrive and be processed, so send it well before your due date if you want to avoid a late fee.

Understanding due dates and late fees

Your due date appears on your bill. ComEd considers a payment late if it is not received by that date. "Received" means the payment has arrived at ComEd's processing center, not the date you sent it. This is why mailing a check close to the due date is risky — it may not arrive in time.

If your payment is late, ComEd adds a late fee to your next bill. The amount varies but is typically a percentage of your balance or a flat fee, depending on your account type. You can avoid this by paying online (fastest), setting up autopay, or calling to make a phone payment at least two business days before the due date.

What to do if you cannot pay the full amount

If you cannot pay your full bill by the due date, contact ComEd before that date. You have options that do not require you to wait until you are behind. ComEd offers budget billing, which spreads your annual costs into equal monthly payments so bills are more predictable. You can also request a payment arrangement, which lets you pay part of the bill now and the rest over a set number of weeks.

ComEd also administers the Low Income Home Energy Assistance Program (LIHEAP) in Illinois, which provides bill assistance to households that meet income limits. You apply through your local Community Action Agency, not through ComEd directly. If you are struggling with your bill, ask ComEd's customer service which Community Action Agency serves your area.

Checking your payment status

After you pay, log into your ComEd account to confirm the payment posted. Online and phone payments usually show within one business day. If you mailed a check, it may take longer. Your account will show the payment date and the new balance owed.

If a payment does not appear after the expected time, contact ComEd at 1-877-426-6331 with your confirmation number or the date you paid. They can look up the payment in their system and tell you when it will post.

Setting up autopay to avoid missed payments

Autopay is the most reliable way to ensure your bill is paid on time every month. Once you enroll, ComEd withdraws the amount due from your chosen bank account or card on your due date. You receive a confirmation email after each payment.

You control autopay completely. You can pause it for a month, change the payment method, or cancel it anytime through your account settings. If your bill amount changes (which it does seasonally for most households), autopay adjusts to the new amount. There is no fee to use autopay, and ComEd does not charge extra for paying by bank account versus a card.

Frequently Asked Questions

Does ComEd charge a fee to pay online or by phone?

No. ComEd does not charge a fee for online payments, mobile app payments, or phone payments made directly through their system. Some third-party payment processors may charge a fee, but ComEd's own channels are free.

What happens if I pay after the due date?

ComEd adds a late fee to your next bill. The exact amount depends on your account type and balance. If you are more than 30 days late, ComEd may disconnect your service. Contact them immediately if you know you will be late — they may be able to set up a payment plan to prevent disconnection.

Can I pay someone else's ComEd bill?

Yes, if you have their account number. You can pay online, by phone, or by mail using their account number. The payment will be applied to that account. You do not need to be the account holder to make a payment.

How do I know if my check payment arrived?

Log into your ComEd account and check your payment history. If the check has been processed, it will appear with the date received. If you mailed it more than two weeks ago and it does not show, call ComEd at 1-877-426-6331 to investigate.

What if I want to change my due date?

You can request a different due date by logging into your account or calling ComEd at 1-877-426-6331. ComEd will try to accommodate your request, though the date you choose must fall within their billing cycle. This is useful if your due date falls before you typically receive income.
