Where to pay your National Grid bill
National Grid accepts bill payments through their website at nationalgrid.com, by phone, by mail, and in person at authorized payment locations. The fastest and most convenient method is online through your National Grid account, where you can pay immediately without waiting for mail delivery or phone hold times.
If you do not have online access or prefer not to use it, you can call National Grid's customer service line (the number is on your bill), mail a check to the address printed on your statement, or visit a payment center in your service area. Each method has different processing times, so choose based on when your payment is due.

Paying online through your National Grid account
Log into your account at nationalgrid.com using 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 other identifying information. Once logged in, select "Pay My Bill" or a similar option in the menu.
Enter the amount you want to pay—you can pay the full balance, a partial amount, or a set-up a recurring payment for the same amount each month. Choose your payment method: bank account (checking or savings) or debit card. Bank account payments are free; debit card payments may carry a small fee depending on your bank. Review the payment details and confirm. The payment posts within one business day.
If you set up a recurring payment, National Grid will charge your account on the same day each month. You can change or cancel this arrangement anytime through your online account. Keep a record of your confirmation number for your records.
Paying by phone
Call the customer service number on your bill. Have your account number ready. A representative will ask you to confirm your identity and the amount you want to pay. You will need to provide either a bank account number and routing number, or a debit card number.
Phone payments are processed immediately and post within one business day. National Grid does not charge a fee for bank account payments made by phone, though debit card payments may incur a fee. Ask the representative for a confirmation number before you hang up.
Paying by mail
Write a check or money order payable to National Grid. Do not send cash. Include your account number on the check. Place the check and your bill stub (or a copy of it) in an envelope and mail it to the address printed on your bill statement.
Mail payments take five to ten business days to arrive and be processed. To avoid a late fee, your payment must be received by the due date on your bill, not postmarked by that date. If your due date is soon, mail is not a reliable option—use online or phone payment instead. Keep a copy of your check or a photo of it for your records.
In-person payment locations
National Grid has authorized payment centers in some service areas where you can pay in person with cash, check, or debit card. Visit nationalgrid.com and search for "payment locations" or call customer service to find the nearest center to you. Hours and accepted payment methods vary by location.
In-person payments are processed on the day you make them. This option is useful if you do not have online or phone access, or if you need to pay with cash. Bring your account number or bill statement with you.
What to do if you cannot pay on time
If you cannot pay your bill by the due date, contact National Grid before the due date passes. Customer service representatives can discuss payment arrangements, such as a short extension or a payment plan spread over several months. These arrangements may help you avoid a late fee or service disconnection.
National Grid may also have hardship programs available if you are struggling with energy costs. Ask about budget billing, which spreads your annual costs evenly across twelve months, or income-based assistance programs. The representative can explain what programs you may be able to use and how to learn more about them.
Understanding your bill due date and late fees
Your due date is printed on your bill statement, usually 20 to 30 days after the bill is issued. If you do not pay by that date, National Grid charges a late fee—the amount varies by state and by how much you owe. The late fee is added to your next bill.
If your payment is more than 30 days late, National Grid may disconnect your service. The company must provide notice before disconnection, but the timeline varies. If you receive a disconnection notice, call immediately to make a payment or arrange a plan. Reconnection may require a deposit or reconnection fee in addition to your overdue balance.
Frequently Asked Questions
Is there a fee to pay my National Grid bill online?
No fee is charged if you pay from a bank account. Debit card payments may carry a small fee depending on your bank's policies. The fee, if any, is shown before you confirm the payment, so you can choose a different payment method if you prefer.
How long does it take for my online payment to show up?
Online payments post to your account within one business day. If you pay after 5 p.m. on a weekday or anytime on a weekend, it may post the next business day. You will receive a confirmation number immediately after you submit the payment.
Can I set up automatic payments so I do not have to pay every month?
Yes. Through your online account, you can set up a recurring payment for the same amount each month on a date you choose. National Grid will charge your bank account or debit card automatically. You can change or stop the recurring payment anytime through your account settings.
What if I pay too much or overpay my bill?
If you overpay, the extra amount becomes a credit on your account. National Grid will apply the credit to your next bill. If you want a refund instead, contact customer service to request one. Refunds are usually processed within two to four weeks.
Can I pay someone else's National Grid bill?
You can pay online or by phone if you have the account number and the account holder's permission. For security reasons, National Grid does not allow third-party payments by mail. If you are paying for someone else regularly, ask them to add you as an authorized user on their account so you can manage payments directly.
