National Grid bills can be paid online through your account, by phone, by mail, or in person at a payment location

National Grid serves electricity and natural gas customers across New York, Massachusetts, and Rhode Island. The fastest way to pay is through your online account at nationalgridus.com, where you can set up a one-time payment or enroll in automatic monthly payments. If you prefer not to use the website, you can call the customer service number on your bill, mail a check, or pay at authorized payment centers in your area.

The method you choose affects when your payment posts to your account and whether you incur a fee. Online and automatic payments typically post within one to two business days at no charge. Phone payments and in-person payments at authorized locations may carry a small fee, usually between $1 and $3. Mailed checks take longer — usually five to seven business days — so mail your payment early if your due date is approaching.

Key Takeaways

  • Online payment through your National Grid account is free and posts within one to two business days.
  • Automatic monthly payments remove the need to remember your due date and can be set up or canceled anytime through your account.
  • Phone payments and in-person payments at authorized locations may charge a fee of $1 to $3 per transaction.
  • Mailed checks take five to seven business days to post, so send them at least a week before your due date to avoid a late payment.
  • Your bill shows your account number, due date, and the mailing address you need for checks.

Paying online through your National Grid account

Go to nationalgridus.com and log in with your username and password. If you do not have an online account, you can create one by entering your account number (found on your bill) and your zip code. Once logged in, select "Pay My Bill" or a similar option in the main menu.

Enter the amount you want to pay — you can pay your full balance, a partial amount, or more than you owe. Choose your payment method: bank account (ACH transfer) or debit or credit card. Bank account payments are free. Card payments may charge a fee, usually $1 to $3, depending on the card type. Select your payment date. If you choose today or tomorrow, the payment posts quickly. If you choose a future date, the payment will process on that day.

Review the details and confirm. You will receive a confirmation number when ready. National Grid will send you an email receipt, and the payment will appear in your account history. Keep the confirmation number in case you need to reference the payment later.

Setting up automatic monthly payments

Automatic payments mean your bill is paid on the same day each month without you having to log in or write a check. Log into your National Grid account and look for "Autopay," "Automatic Payment," or "Recurring Payment" in the account settings or billing section.

Choose whether you want to pay your full bill each month or a set dollar amount. Select your payment method — bank account (free) or card (may have a fee). Pick the day of the month you want the payment to occur. Most people choose a date shortly after their bill arrives, so they know the amount. Confirm your enrollment.

You can change or cancel automatic payments anytime through your account settings. There is no penalty for stopping. If you cancel, you will need to pay future bills manually or set up a new automatic payment.

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. You will provide your bank account information or card details over the phone. Most phone payments charge a fee of $1 to $3.

Ask the representative when the payment will post and request a confirmation number. Write down both. Phone payments typically post within one to two business days, though some may take longer depending on your bank.

Paying by mail

Write a check or money order payable to National Grid. Do not send cash. Include your account number on the check — write it in the memo line or on the back. Place the check and your bill stub (if you have one) in an envelope and mail it to the address printed on your bill.

Mail your payment at least one week before your due date to account for postal delays. Mailed payments typically take five to seven business days to reach National Grid and post to your account. If your due date is fewer than seven days away, use online payment, phone payment, or an in-person payment location instead to avoid a late fee.

Paying in person at authorized locations

National Grid has authorized payment centers and partner locations where you can pay in cash, check, or card. These locations vary by region. Visit nationalgridus.com and search for "payment locations" or "where to pay" to find the nearest center to you, or call customer service for a list.

Bring your account number and the amount you want to pay. In-person payments at authorized locations may charge a fee of $1 to $3. Ask the cashier for a receipt and keep it for your records. The payment usually posts within one to two business days.

What to do if you miss your due date

If your payment does not arrive by the due date shown on your bill, National Grid 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 for the exact amount in your area.

Pay as soon as you realize the payment is late. Late fees accumulate, and if you remain unpaid for 30 days or more, National Grid may disconnect your service. If you are having trouble paying, contact National Grid customer service to ask about payment plans or hardship programs that may be available in your state.

Frequently Asked Questions

Is there a fee to pay my National Grid bill online?

No fee if you pay from your bank account (ACH transfer). Credit and debit card payments may charge $1 to $3. Phone and in-person payments at authorized locations also may charge a fee. Check your payment method options during checkout to see the fee before you confirm.

How long does it take for my online payment to show up?

Online payments typically post within one to two business days. Payments made on a weekend or holiday may take longer. You will receive a confirmation number when ready after you submit, and you can check your account balance online to see when the payment posts.

Can I pay someone else's National Grid bill?

Yes, if you have their account number. You can pay online, by phone, or by mail using their account number. The payment will be applied to their account. If you are paying by mail, include their account number on the check so the payment is credited correctly.

What happens if I pay too much?

The overpayment becomes a credit on your account. National Grid will explore it to your next month's bill. If you want a refund instead, contact customer service and request one. Refunds typically take one to two weeks to process.

Can I set up automatic payments if I have a budget billing plan?

Yes. Automatic payments work with budget billing. Your payment will be the budgeted amount each month, not the actual usage amount. If your actual bill differs at the end of the year, you will owe or receive a credit for the difference.
