Where to Pay Your National Grid Bill

National Grid operates in New York and Massachusetts, and the way you pay depends on which state you're in and which payment method you choose. You can pay online through your account, by phone with a representative, by mail, or in person at a payment location. The fastest and most common route is online through the National Grid website or mobile app, where you can see your balance when ready and choose when the payment posts.

If you don't have internet access or prefer to speak with someone, you can call National Grid's customer service line. The phone number appears on your bill. Payment by mail takes longer — typically 7 to 10 business days — so use this method only if you're paying well before your due date.

Key Takeaways

  • Online payment through the National Grid website or app is the fastest method and lets you schedule payments in advance or pay when ready.
  • Phone payment requires your account number and a debit card or bank account, and a representative can walk you through the process.
  • Mail payments should be sent at least 10 business days before your due date to avoid late fees.
  • National Grid does not charge a fee for online or phone payments made with a bank account, but some payment methods may carry a small fee.

Paying Online Through Your National Grid Account

Go to the National Grid website for your state — either nationalgridus.com (for New York) or the Massachusetts site. Click "Pay My Bill" or "Make a Payment" in the top menu. You'll be asked to log in with your account number and password, or to create an account if you don't have one yet.

Once logged in, your current balance and due date will appear on the screen. You can pay the full amount, a partial amount, or set up a recurring payment that happens on the same day each month. Choose your payment method — bank account (no fee), debit card (may have a small fee), or credit card (may have a fee). Enter the payment amount and confirm the date you want it to post. The payment will be processed when ready if you choose today's date, or on the date you specify if you schedule it ahead.

Keep your confirmation number. National Grid will send you an email receipt, but the confirmation number on the screen is proof the payment was submitted if you need it later.

Paying by Phone

Call the customer service number on your bill. A representative will ask for your account number and the amount you want to pay. Have your debit card or bank account information ready. The representative will process the payment over the phone and give you a confirmation number before the call ends.

Phone payments are processed the same day if you call during business hours. If you call after hours, the payment will be queued and processed the next business day. There is no fee for paying by phone with a bank account, though some payment methods may carry a charge.

Paying by Mail

Write a check or money order for the amount due. Include your account number on the check. Mail it to the address printed on your bill — this address is different for New York and Massachusetts customers, so check your specific bill.

Mail payments typically take 7 to 10 business days to reach National Grid and post to your account. To avoid a late fee, mail your payment at least 10 business days before the due date shown on your bill. If you're cutting it close, use online or phone payment instead.

Setting Up Automatic Payments

If you want your bill paid the same day each month without having to remember, you can set up autopay through your online account. Log in, go to "Billing" or "Payment Settings," and select "Enroll in AutoPay." Choose the day of the month you want the payment to come out — many people choose the day after they get paid — and confirm your bank account or card information.

You can change or cancel autopay at any time through your account. National Grid will send you a reminder email a few days before each automatic payment is scheduled. If your balance changes month to month, you can set autopay to pay the full statement balance, or you can set a fixed amount and adjust it manually when needed.

What to Do If You Can't Pay the Full Amount

If your bill is due but you can't pay it all at once, call National Grid's customer service number. You may be able to set up a payment plan that breaks the balance into smaller amounts due on different dates. The representative can explain what options are available based on your account history and the amount owed.

If you're struggling with your bill because of a hardship — job loss, medical emergency, or other crisis — ask about hardship programs. National Grid has programs in both New York and Massachusetts that may help lower your bill or give you more time to pay. The representative can tell you whether you might be may be able to access and how to proceed.

Late Payments and Reconnection

If your payment doesn't arrive by the due date, National Grid will charge a late fee. The amount varies but is shown on your bill. If you're more than a certain number of days late — typically 20 to 30 days depending on your state — National Grid may disconnect your service. You'll receive a notice before disconnection happens, usually giving you several days to pay or contact them.

If your service is disconnected, you'll need to pay the full past-due balance plus a reconnection fee to have power restored. Reconnection can take 24 to 48 hours. If you receive a disconnection notice, call National Grid when ready rather than waiting — a representative may be able to work out a payment plan that stops the disconnection.
