Nicor Gas serves natural gas to nearly four million customers across Illinois, and like any utility company, they offer multiple ways to pay your monthly bill. This guide walks through the actual payment options available, how each one functions, and what you might want to consider when choosing between them. Understanding your choices matters because the method you select affects how you manage your money, when funds leave your account, and how you track your payments.

Nicor Gas structures their payment system around three main categories: online and phone payments, automatic payments, and in-person payments at authorized locations. Within each category, there are specific methods with different timing, fees, and requirements. For example, paying online through your Nicor account works differently than setting up automatic withdrawal from your bank account—one requires you to initiate payment each month, while the other happens without action on your part.
The company also distinguishes between payment methods based on speed. Some methods post to your account within one business day, while others may take several days to process. If you're close to a due date, the timing difference between methods matters significantly. A payment made by phone on a Friday might not post until Monday or Tuesday, whereas a payment made through automatic bank draft typically posts on a scheduled date you choose.
Your choice of payment method can also affect your billing flexibility. Some payment options allow you to pay partial amounts, while others work best for full monthly statements. Some methods generate immediate confirmation, while others require you to monitor your account to verify the payment posted correctly.
Practical takeaway: Before selecting a payment method, identify what matters most to you—whether that's convenience, timing, avoiding fees, or having a paper trail of payments.
Nicor Gas provides an online payment portal accessible through their website and mobile app. Creating an account is free, and once you're set up, you can log in anytime to see your current bill, payment history, and usage information. The online portal is available 24 hours a day, seven days a week, which means you're not limited to business hours when you need to make a payment.

When you pay through the online portal, you enter your bill amount or choose to pay a different amount, and you provide your payment information—typically a bank account (checking or savings) or debit card. Nicor processes these payments the same business day if submitted before a certain cutoff time, usually around 5 p.m. The payment then appears as posted within one business day. This relatively quick turnaround matters if you're paying close to your due date.
One important detail: Nicor Gas does not charge a fee for paying with a bank account through their online portal. However, if you choose to pay with a debit or credit card through their portal, a fee applies. The fee varies but typically ranges from 2% to 3% of your payment amount. This means on a $150 bill paid with a debit card, you might pay an additional $3 to $4.50. Over a year, this adds up significantly, which is why many customers reserve card payments for emergencies when a bank account isn't accessible.
The online portal also allows you to view and download your bills, set up payment reminders, and review your payment history going back several years. This documentation can be useful if you ever need to dispute a charge or verify that a payment posted correctly. You can also update your contact information, add authorized users to your account, and manage service preferences all through the same portal.
Practical takeaway: Use bank account payments through the online portal to avoid fees, and plan to submit payments before the afternoon cutoff to ensure same-day processing.
Automatic payment, often called automatic bank draft or autopay, removes the need to log in and pay each month manually. You authorize Nicor Gas to withdraw your payment directly from your checking or savings account on a date you specify—typically the same day each month or around your bill due date. Once set up, the system repeats without requiring any action from you month after month.

Nicor offers two versions of automatic payment: one where the amount withdrawn matches your current bill amount each month, and another where you set a fixed amount to be withdrawn. The fixed-amount option works well if your bills are relatively consistent, and you want predictability in your monthly budget. The variable-amount option, where Nicor withdraws whatever your actual bill is that month, requires less adjustment if your usage changes seasonally—your winter heating bills might be much higher than summer bills, and the withdrawal amount adjusts automatically.
There is no fee for automatic payment when you use a bank account. This is one of the primary reasons many households choose this method over other options. The payments process reliably, and you don't have to remember to pay each month. This structure also tends to result in fewer late payments because the system operates on a schedule you set in advance. If you travel, change jobs, or experience other life disruptions, your utility bill still gets paid on time.
Setting up automatic payment requires you to provide banking information—your account number and routing number. Nicor maintains this information securely and uses it only for the authorized withdrawals. You can modify or cancel automatic payments anytime through your online account or by calling Nicor customer service. If you need to stop a payment before it processes (for example, if you notice an error in your bill), you can typically cancel it up to a business day before the scheduled withdrawal.
One consideration with automatic payment: you need to monitor your account to ensure the correct amounts are being withdrawn and that payments are posting as expected. While the system is reliable, occasional discrepancies can occur—a bill might be calculated incorrectly, or a payment might not process due to insufficient funds. Reviewing your account monthly takes just a few minutes and catches problems early.
Practical takeaway: Automatic payment works best if you have a stable checking or savings account, check your account monthly to verify payments, and want a hands-off approach to paying your utility bill.
Not everyone prefers paying online, and Nicor Gas recognizes this by offering phone and mail payment options. Paying by phone means calling Nicor's customer service line, speaking with a representative, and providing your payment information over the phone. This method works for customers who don't use online systems regularly or prefer human interaction when handling financial transactions.

When you call to pay, have your bill or account number ready, along with your payment method information. Representatives can process payments from bank accounts or debit/credit cards. Like online payments, paying with a bank account over the phone carries no fee, while card payments incur a processing fee. The payment posts within one to two business days. Calling during business hours ensures you reach a representative quickly, though Nicor also offers automated phone payment systems that operate 24/7—these systems guide you through payment using your phone keypad without requiring a representative.
Mailing a check or money order represents the most traditional payment method. You write a check, include it with your bill stub (or at minimum your account number), and mail it to the address printed on your bill. The payment arrival time depends on postal service speed—typically three to seven business days. Because of this delay, you need to mail checks well before your due date to avoid late fees. Unlike digital payments, checks create a physical record; when the check clears your bank, you have documentation of the transaction.
Mail payments involve a slight inconvenience factor that some customers don't mind and others want to avoid. You need stamps, envelopes, and time to write and mail the check. You also need to track whether the payment arrived and posted, since there's no instant confirmation. However, mail payments carry no fee and work for customers without bank accounts or regular internet access. Some customers choose mail payment specifically for the paper trail and control—you know exactly when you sent the payment and have your cancelled check as proof.
Nicor also offers in-person payment locations in certain areas where customers can pay directly at authorized payment centers. Availability varies by region, so you'd need to check Nicor's website or call to find locations near you. In-person payments typically post the same business day and involve no fees.
Practical takeaway: Phone payments work for occasional or urgent needs; mail payments require planning ahead but create a paper record; in-person payments offer same-day posting without fees if a location is convenient.
