Where to pay your New Jersey Natural Gas bill
New Jersey Natural Gas (NJNG) lets you pay through their website, by phone, by mail, or in person at a payment center. The fastest route is online at ninjgas.com — you can pay when ready with a bank account or debit card, and the payment posts the same day if you submit before 5 p.m. Eastern time on a business day.
If you prefer not to use the website, you can call NJNG's automated payment line at 1-800-221-0051 to pay by phone with a debit card or bank account. A live representative can also take your payment over the phone if you call during business hours, though you may wait longer than the automated system.
Mail payments to the address on your bill — typically the lockbox address listed under "Payment Information." Mail takes 7 to 10 business days to arrive and post, so send it well before your due date if you want to avoid a late fee. You can also pay in person at an NJNG payment center, though these are limited to certain locations; call 1-800-221-0051 to find the nearest one to you.
Key Takeaways
- Online payment at ninjgas.com is the fastest method and posts the same day if submitted before 5 p.m. on a business day.
- Phone payment through the automated line (1-800-221-0051) works with a debit card or bank account and takes a few minutes.
- Mail payments take 7 to 10 business days to post, so send them at least two weeks before your due date to avoid late fees.
- You will need your account number (found on your bill) and a payment method ready before you start, regardless of which route you choose.
Paying online through your NJNG account
Go to ninjgas.com and click "Pay My Bill" or "Make a Payment" on the homepage. You will be asked to log in with your account number and either your password or the last four digits of your phone number on file. If you do not have an online account yet, you can create one by clicking "Register" and following the prompts — this takes about five minutes and requires your account number and service address.
Once logged in, your current balance and due date appear on the screen. Enter the amount you want to pay (you can pay the full balance, a partial amount, or set up a recurring payment). Choose your payment method: bank account (which takes 1 to 3 business days to post) or debit card (which posts the same day). Review the details and submit. You will receive a confirmation number when ready — save or print this for your records.
If you pay by bank account, NJNG will deduct the funds within 1 to 3 business days. If you pay by debit card, the charge posts the same day. Either way, your account will reflect the payment within the timeframe shown on the confirmation screen. If you do not see the payment posted by the date promised, log back in and check your account status, or call 1-800-221-0051 to verify.
Setting up automatic payments
Automatic payments (also called "budget billing" or "recurring payments" depending on the program) let NJNG withdraw your bill amount from your bank account on a date you choose each month. This prevents missed payments and late fees, though you remain responsible for reviewing your bill to catch errors.
To set up automatic payments online, log into your account at ninjgas.com, go to "Billing & Payment," and select "Enroll in AutoPay" or "Set Up Recurring Payment." Choose the date you want the payment to come out each month (typically between the 1st and the 28th), confirm your bank account details, and submit. The first automatic payment will process on the date you selected in the following month.
You can change or cancel automatic payments anytime by logging back into your account or calling 1-800-221-0051. If you cancel, you will need to resume paying manually. If a payment fails because your bank account is closed or has insufficient funds, NJNG will attempt to contact you and may charge a returned-payment fee.
What happens if you miss a payment
If your payment does not arrive by the due date on your bill, NJNG will charge a late fee. The amount varies but is typically a percentage of your bill or a flat fee — check your bill or account online to see what NJNG charges. A late payment also appears on your account and may affect your credit report if it remains unpaid for 30 days or more.
If you fall behind, NJNG will send you a notice warning that service may be disconnected if you do not pay within a set timeframe (usually 10 to 15 days). You can avoid disconnection by paying the full past-due amount, setting up a payment plan, or contacting NJNG to discuss hardship options. Call 1-800-221-0051 to speak with a representative about your options before your service is shut off.
New Jersey has rules that limit when NJNG can disconnect service during winter months (November through March), even if you are behind on payments. If you cannot pay your full bill, ask about a winter protection plan or payment arrangement when you call.
Payment methods and fees
NJNG accepts payment by bank account (no fee), debit card (no fee online, though some third-party payment processors may charge a small fee if you use their service), and check or money order by mail (no fee). Paying by credit card through a third-party processor typically costs 2 to 3 percent of your bill amount, so most people avoid this unless they need the credit card rewards.
There is no fee to pay online, by phone, or by mail directly to NJNG. If you use a third-party bill-pay service (such as your bank's bill-pay feature), check whether that service charges a fee — most do not, but some banks charge a small amount for expedited delivery.
Late fees explore only if your payment does not arrive by the due date. Returned-check fees explore if a check you mail bounces. Reconnection fees explore if your service is disconnected and you later pay to have it restored. None of these fees are charged if you pay on time.
Checking your payment status
Log into your account at ninjgas.com anytime to see your current balance, due date, and payment history. Your account shows all payments received in the past 12 months, the date each payment posted, and the amount. If you paid online or by phone, the payment usually appears within 24 hours; if you mailed a check, it may take 7 to 10 business days.
If you do not see a payment you made, check the confirmation number or receipt you received when you submitted it. The confirmation shows the expected posting date. If the payment has not appeared by that date, call 1-800-221-0051 with your confirmation number and account number, and a representative can look up the payment in their system.
You can also request a payment history by mail or email if you need documentation for a dispute or for your records. Ask for this when you call customer service.
Frequently Asked Questions
Can I pay my bill with a credit card?
NJNG does not directly accept credit cards on their website or by phone. However, you can use a third-party payment processor to pay by credit card — these typically charge 2 to 3 percent of your bill as a convenience fee. Most people pay by bank account or debit card instead to avoid the fee.
What if I pay online but my payment does not show up?
Online payments usually post within 24 hours if you pay by debit card, or within 1 to 3 business days if you pay by bank account. Check your confirmation number and the expected posting date shown on your receipt. If the payment has not appeared by that date, call 1-800-221-0051 with your confirmation number and account number.
Can I set up a payment plan if I cannot pay my full bill?
Yes. Call 1-800-221-0051 and ask about a payment arrangement. NJNG can spread your past-due balance over several months. You must continue paying your current bill on time while you pay down the past-due amount, or the arrangement may be cancelled.
Is there a grace period after the due date?
No. Late fees explore if your payment is not received by the due date shown on your bill. Mail payments take 7 to 10 days to arrive, so send them well in advance. Online and phone payments post the same day or within a few business days, so use those methods if your due date is approaching.
What if I overpay my bill?
The overpayment will be credited to your account and applied to your next bill. You can request a refund of the overpayment by calling 1-800-221-0051, though NJNG may keep the credit on your account instead to cover future bills.
