Where to pay National Grid and what you need

National Grid operates in New York and Massachusetts, and the company offers several ways to pay your bill. You can pay online through your account, by phone, by mail, or in person at a payment location. The fastest way is usually online — you can set it up in a few minutes and see the payment post within one to two business days.

Before you pay, have your bill in front of you. You will need your account number, which appears in the upper right corner of your bill. If you are paying by mail, you can send a check to the address printed on your bill. If you are paying online or by phone, National Grid will ask for your account number and the amount you want to pay.

Key Takeaways

  • National Grid serves customers in New York and Massachusetts, and you can pay online, by phone, by mail, or at authorized payment locations.
  • Online payment through your National Grid account is the fastest method and usually posts within one to two business days.
  • You will need your account number, which is printed on your bill, to pay by any method.
  • If you set up automatic payments, your bill will be paid on the same day each month without you having to remember.
  • Late payments may result in a late fee and can affect your service, so paying by your due date matters.

Paying online through your National Grid account

Go to the National Grid website for your state — either nationalgridus.com/ny or nationalgridus.com/ma — and log into your account. If you do not have an online account yet, you can create one by entering your account number and other identifying information. Once you are logged in, look for "Pay My Bill" or a similar option in the main menu.

Enter the amount you want to pay and choose your payment date. National Grid will show you the processing time — usually one to two business days. You can pay with a debit card, credit card, or bank account. If you use a credit card, National Grid may charge a convenience fee, so check before you confirm. Bank account payments typically have no fee.

After you submit your payment, you will see a confirmation number. Write this down or take a screenshot. The payment will show as pending for a day or two, then post to your account. You can check the status by logging back into your account.

Setting up automatic payments

If you want your bill paid the same day each month without having to remember, you can set up automatic payments through your online account. Log in, find the autopay or automatic payment option, and choose the day you want the payment to come out. You can use your bank account or a debit card.

Automatic payments are useful if your bill amount stays roughly the same each month. You can change or cancel the autopay at any time through your account. If your bill varies a lot — for example, if you use much more electricity in summer — you may want to pay manually each month so you can see what you owe before the money leaves your account.

Paying by phone

Call National Grid's customer service line. The phone number is on your bill. Have your account number ready. A representative will ask you how much you want to pay and what payment method you want to use — debit card, credit card, or bank account. They will process the payment over the phone and give you a confirmation number.

Phone payments usually post within one to two business days, the same as online payments. There may be a convenience fee if you pay with a credit card. Ask the representative about the fee before you give your card number.

Paying by mail

Write a check for the amount you owe. Do not send cash. On the check, write your account number in the memo line so National Grid knows which account to credit. Put the check in an envelope with the payment stub from your bill — the stub has the mailing address printed on it.

Mail payments take longer than other methods because of postal time. Send your check at least one week before your due date to make sure it arrives on time. National Grid will not consider your payment late if it is postmarked by the due date, but it may take several more days to process after it arrives.

Paying at a walk-in location

National Grid has authorized payment locations in some areas where you can pay in person with cash, check, or debit card. These are often at grocery stores, check-cashing services, or utility payment centers. Call National Grid or check their website to find a location near you.

In-person payments usually post to your account within one business day. This method is useful if you prefer to pay with cash or if you want to see your payment processed right away. Bring your account number or your bill so the payment center can credit the right account.

What happens if you pay late

Your due date is printed on your bill. If your payment does not arrive by that date, National Grid will charge a late fee. The amount of the late fee varies, but it is usually a percentage of your bill or a flat amount — check your bill or account for the exact fee.

If you are more than a certain number of days late — usually 30 days — National Grid may shut off your service. Before that happens, you will receive a notice. If you cannot pay the full amount, contact National Grid right away to ask about payment plans or other options. Many utility companies will work with you if you reach out before your service is cut off.
