How to Pay Your ComEd Bill Online

ComEd Online Bill Pay Basics

ComEd bill pay online lets you pay your electric bill through ComEd's website or mobile app instead of mailing a check or calling. You log into your account, enter a payment amount, choose a payment date, and pick your payment method — usually a bank account or debit card. The payment posts to your account within one to two business days, though you can schedule payments up to 30 days in advance.

ComEd is the electric utility serving northern Illinois, including Chicago and surrounding areas. If you receive a ComEd bill, you have a ComEd account and can set up online bill pay through their system.

Key Takeaways

• You log into your ComEd account on their website or app and enter your payment amount, date, and payment method to pay online.
• Payments from a bank account (ACH transfer) are free, while debit or credit card payments usually charge a fee of around 2 to 3 percent.
• You can schedule a one-time payment or set up automatic recurring payments so your bill is paid the same day each month.
• Payments typically post within one to two business days, but you can schedule them up to 30 days ahead if you want to pay early.

Setting Up Your ComEd Online Account

Before you can pay online, you need a ComEd account registered to your name and address. If you just moved into a home or apartment with ComEd service, you should have received a welcome letter with your account number. If you already pay ComEd by mail or phone, your account exists — you just need to register it online.

Go to ComEd's website and click "Create Account" or "Log In". You will need your account number (found on your bill), your service address, and a valid email. ComEd will send you a verification email; click the link to confirm. Once verified, you can log in and set up bill pay.

If you cannot find your account number, look at the top right of your ComEd bill. It is usually a nine-digit number. If you have lost your bill, you can call ComEd customer service at 1-877-426-6331 and they will provide your account number over the phone.

Choosing Your Payment Method

ComEd accepts payment through a bank account (checking or savings), debit card, or credit card. Each method has different costs and timing.

Bank account (ACH transfer) is free and is the most common choice. You enter your routing number and account number, and ComEd pulls the payment directly from your bank. This method takes one to two business days to post. Debit cards and credit cards charge a convenience fee — usually around 2 to 3 percent of your payment amount. A $100 payment might cost $2 to $3 extra. These card payments also post within one to two business days.

If you are paying a large bill, the bank account method saves you money. If you want to earn credit card rewards or need to use a card for cash flow reasons, the fee may be worth it to you. Choose whichever method fits your situation.

Making a One-Time Payment

Log into your ComEd account on the website or app. Look for "Pay My Bill" or "Make a Payment" — the exact wording varies slightly between the website and app, but it is usually on the main dashboard or in a menu.

Enter the amount you want to pay. You can pay your full bill balance, a partial amount, or more than you owe (the extra will be a credit on your account). Select your payment date — you can pay today or schedule it for any day up to 30 days from now. Choose your payment method (bank account, debit card, or credit card) and enter the details if you have not saved them before. Review the payment summary and confirm.

You will receive a confirmation number on screen and via email. Keep this number for your records. The payment will post to your account within one to two business days, though the exact timing depends on your bank and the day of the week you submit it.

Setting Up Automatic Recurring Payments

If you want ComEd to withdraw your bill payment automatically each month, you can set up a recurring payment. This is useful if you want to avoid late fees or straightforward prefer not to log in each month.

In your ComEd account, look for "Autopay" or "Automatic Payments" — usually under account settings or the bill pay section. You will choose a payment date (for example, the 15th of each month), a payment method, and whether you want to pay your full bill or a fixed amount each month. ComEd will then withdraw that payment on your chosen date every month until you cancel it.

You can cancel or change your autopay settings at any time by logging back into your account. If you set autopay to pay your full bill amount, the payment will adjust automatically if your bill changes — useful during seasons when your usage varies.

What to Do If Your Payment Does Not Post

Payments usually post within one to two business days. If more than two business days have passed and your payment has not shown up on your account, log back into ComEd and check your payment history. You should see the payment listed with a status — either "pending" or "posted".

If the payment shows as pending, wait one more business day. If it shows as posted but your bill balance has not changed, contact ComEd customer service at 1-877-426-6331. Have your confirmation number ready. They can verify the payment was received and investigate any delays.

If you scheduled a payment for a future date and need to cancel it, log into your account and look for "Scheduled Payments" or "Pending Payments". You can cancel any payment that has not yet posted. Once a payment has posted, you cannot cancel it, but you can request a refund through customer service.

Frequently Asked Questions

Can I pay my ComEd bill through my bank's bill pay system instead?

Yes. Many banks let you set up bill pay to ComEd through your bank's website or app. You enter ComEd's mailing address and your account number, and your bank sends a check or electronic payment. This method is free but may take longer — usually five to seven business days. ComEd's online system is faster and gives you more control over the exact posting date.

What happens if I pay more than I owe?

The extra amount becomes a credit on your account. ComEd will explore it to your next bill. If you move or close your account, you can request a refund of any remaining credit by calling customer service.

Is it safe to enter my bank account information on ComEd's website?

ComEd's website uses encryption to protect your information. Your bank account and card details are not stored in plain text. That said, only enter your information on the official ComEd website or app — not through a link in an email or text, which could be a phishing attempt. When in doubt, go directly to ComEd.com and log in yourself.

Can I pay my ComEd bill by phone?

Yes. Call ComEd customer service at 1-877-426-6331 and a representative can take your payment over the phone using a bank account or card. This method also charges a convenience fee for card payments. Online payment is usually faster and easier if you prefer to handle it yourself.

What if I want to dispute a charge on my bill before I pay?

Contact ComEd customer service before you pay. Explain the issue and they can investigate. You are not required to pay a disputed amount while they review it. Once the dispute is resolved, you can pay the correct amount through online bill pay.
