National Grid US offers online bill payment through its website and mobile app, letting you pay from your bank account or debit card without mailing a check or calling a representative.
National Grid US serves customers in Massachusetts, New York, and Rhode Island. The company operates separate websites for each state — National Grid Massachusetts, National Grid New York, and National Grid Rhode Island — so your first step is finding the correct portal for your location.
Once you log in with your account number and password, you can schedule a one-time payment or set up automatic recurring payments. The payment reaches your account within one to two business days if you submit it before the cutoff time, which is typically 5 p.m. Eastern Time on the due date.
Key Takeaways
- National Grid US bill payment is available through state-specific websites (Massachusetts, New York, or Rhode Island) and the mobile app for each state.
- You need your account number and a password to log in; if you do not have a password, you can create one during your first visit.
- Payments made before 5 p.m. Eastern Time on your due date post within one to two business days and count as on-time.
- You can pay once or set up automatic monthly payments from a checking or savings account, or use a debit card for one-time payments.
- If you miss the online cutoff, you can still call the payment line or mail a check, though these routes take longer to process.
Finding Your State's Payment Portal
National Grid US does not operate a single national website. Instead, each state runs its own portal. Go to the website for your state: nationalgridus.com/Massachusetts, nationalgridus.com/NewYork, or nationalgridus.com/RhodeIsland. You can also search "National Grid [your state] pay bill online" to reach the correct page.
Once on the site, look for a link labeled "Pay My Bill," "Make a Payment," or "Billing & Payment." This link is usually on the homepage or in the top navigation menu. Click it to enter the payment portal.
Logging In and Setting Up Your Account
To pay online, you need to log in with your account number and password. Your account number appears on your paper bill in the upper right corner or on the first page. If you have never logged in before, you will need to create a password.
Click "Create an Account" or "Register" on the login page. Enter your account number, email address, and a new password. National Grid will send a confirmation email to verify your address. Once confirmed, you can log in and make payments when ready.
If you forget your password, use the "Forgot Password" link on the login page. National Grid will send a reset link to the email address on file. If you do not remember the email address you used to register, call National Grid's customer service line for your state — the number is on your bill — and a representative can help you recover your account.
Making a One-Time Payment
After logging in, select "Make a Payment" or "Pay Now." The portal will show your current balance and due date. Enter the amount you want to pay — you can pay the full balance, the minimum, or any amount in between.
Choose your payment method: checking account, savings account, or debit card. If you use a bank account, you will need your routing number and account number. If you use a debit card, enter the card number, expiration date, and CVV. National Grid does not charge a fee for bank account payments, but some debit card payments may incur a small fee depending on your card issuer.
Select your payment date. If you choose a date before 5 p.m. Eastern Time on your due date, the payment will post on time. If you schedule it for after that cutoff or after your due date, it will still process but may be recorded as late. Review the details and confirm the payment. You will receive a confirmation number when ready — save or print this for your records.
Setting Up Automatic Monthly Payments
If you prefer not to log in each month, you can set up automatic payments from your bank account. Log in, go to "Billing & Payment" or "Manage Payments," and look for "Autopay" or "Automatic Payment." Select this option and choose your bank account as the payment method.
You will need to decide whether to pay your full bill each month or a fixed amount. Most customers choose to pay the full balance automatically on a date they select — typically a few days before the due date. National Grid will deduct the payment automatically each month until you cancel.
To cancel automatic payments, log back in and turn off the autopay setting. You can also call National Grid's customer service line to cancel. Make sure you cancel before the next scheduled payment date if you do not want the charge to go through.
What Happens After You Submit Payment
Once you submit a payment online, National Grid sends a confirmation number to your email address. The payment typically posts to your account within one to two business days. Payments submitted before 5 p.m. Eastern Time on your due date are considered on-time, even if they do not show up in your account until the next day.
You can check the status of your payment by logging back in and viewing your account history or recent transactions. If more than two business days have passed and the payment does not appear, contact National Grid's customer service line for your state. Have your confirmation number ready.
Alternatives If Online Payment Does Not Work
If you cannot access the online portal or prefer not to use it, National Grid offers other payment methods. You can mail a check to the address on your bill — allow 7 to 10 business days for it to arrive and post. You can also call the automated phone payment line for your state, which accepts debit card or bank account payments over the phone. The phone number is on your bill.
If you are behind on your bill or facing hardship, contact National Grid's customer service to discuss payment plans or other options. Representatives can sometimes extend your due date or set up a schedule that works with your income.
Frequently Asked Questions
Do I have to create an online account to pay my bill?
No. You can pay by phone using the automated payment line, by mail, or in person at a National Grid office. Online payment is optional and offered for convenience, but you can use any method listed on your bill.
What if I pay online but my bill shows as unpaid the next day?
Online payments take one to two business days to post. If two business days have passed and the payment still does not show, contact National Grid with your confirmation number. A representative can look up the payment and confirm it went through.
Can I pay someone else's National Grid bill online?
You can pay an account if you have the account number and are authorized on the account. If you are not the account holder, contact National Grid to ask about adding yourself as an authorized payer. Otherwise, the account holder must set up the payment themselves or give you permission to use their login.
Is there a fee to pay my bill online?
National Grid does not charge a fee for online payments made from a bank account. Some debit card payments may incur a small fee from your card issuer, not from National Grid. Check with your bank if you are unsure.
What time do I need to pay to avoid a late fee?
Payments submitted before 5 p.m. Eastern Time on your due date post on time. If you submit after 5 p.m. or after your due date, the payment may be recorded as late even if it processes the next day. To be safe, submit by mid-afternoon on your due date.
