Log in to your National Grid account to pay your bill
National Grid's online portal lets you view your bill, make a one-time payment, or set up automatic payments from your computer or phone. To get your free guide, go to the National Grid website for your state — the login page differs depending on whether you're a customer in New York, Massachusetts, or Rhode Island.
You'll need your account number (found on your paper bill) and a password. If you don't have an online account yet, you can create one in a few minutes using your account number and email address. Once you're logged in, your bill and payment options appear on your dashboard.
Key Takeaways
- National Grid's website is state-specific, so you must use the login portal for New York, Massachusetts, or Rhode Island depending on where you receive service.
- You can pay a bill when ready with a debit card, credit card, or bank account, or set up automatic monthly payments to avoid late fees.
- Your account number appears on your paper bill and is required to create an online account if you don't already have one.
- Payment processing takes one to two business days for bank transfers and is when ready for credit or debit card payments.
Finding the correct National Grid login page for your state
National Grid operates in three states, and each has its own login portal. If you use the wrong one, you won't find your account. Check your paper bill to see which state you're in, then visit that state's website.
For New York customers, the login is at the main National Grid website. Massachusetts customers log in through a separate portal, and Rhode Island customers use a third portal. Each one asks for the same information — your account number and password — but the websites themselves are different. Bookmarking the correct one saves time on future payments.
Creating a new online account if you don't have one yet
If you've never logged in before, you'll see a "Create Account" or "Register" link on the login page. Click it and enter your account number, which is printed on your bill. You'll also provide an email address and create a password.
National Grid will send a confirmation email to verify your address. Click the link in that email to set up your account. This usually takes a few minutes, though it can take up to an hour during high-traffic times. Once confirmed, you can log in and see your bill when ready.
Paying your bill with a one-time payment
After you log in, look for a "Pay Now" or "Make a Payment" button on your dashboard. Click it and you'll see your current bill amount and due date. You can pay the full amount or a partial payment.
National Grid accepts debit cards, credit cards, and bank account transfers. Credit and debit card payments process when ready, though they may take one business day to show on your account. Bank account payments (ACH transfers) take one to two business days to process. There is no fee for paying by bank account, but credit and debit card payments may include a processing fee — the website will show you the fee before you confirm.
Setting up automatic monthly payments
If you want to stop logging in each month, you can set up automatic payments from your bank account. After you log in, find the "Autopay" or "Automatic Payment" section. Choose your payment date (usually between the 1st and the 28th of the month) and the account you want to pay from.
Automatic payments pull money directly from your checking or savings account on the date you choose. You can change or cancel autopay anytime by logging back in. This method has no fee and ensures you never miss a due date, which helps you avoid late charges.
What to do if you can't log in or forgot your password
If you've forgotten your password, click the "Forgot Password" link on the login page. Enter your account number and email address, and National Grid will send a password reset link to your email. Click that link and create a new password.
If you don't receive the reset email within a few minutes, check your spam folder. If the email never arrives or you can't remember your account number, you'll need to call National Grid's customer service. They can verify your identity and help you regain access. The phone number is on your paper bill.
Payment timing and when your bill is considered paid
National Grid considers your bill paid on the date the payment is processed, not the date you submit it. Credit and debit card payments process when ready, so your payment counts as received the same day. Bank account transfers take one to two business days, so if you pay on a Friday, it may not process until Monday or Tuesday.
Your due date is printed on your bill. As long as your payment is processed by that date, you won't be charged a late fee. If you're cutting it close, use a credit or debit card to may support same-day processing. If you mail a check instead, National Grid needs to receive it by the due date, which is why online or phone payments are faster and more reliable.
Frequently Asked Questions
Can I pay my National Grid bill without creating an online account?
Yes. You can pay by phone by calling the number on your bill, by mail by sending a check, or in person at a payment location. Online accounts are optional but convenient because you can see your bill anytime and set up automatic payments.
Is there a fee to pay my bill online?
There is no fee for paying by bank account transfer. Credit and debit card payments may include a processing fee, which National Grid shows you before you confirm the payment. The fee is usually a small percentage of your bill.
What if I pay my bill but it still shows as unpaid on my account?
Bank account payments take one to two business days to process, so your account may not update when ready. If you paid by credit or debit card, it should show within a few hours. If more than two business days have passed and a bank transfer still hasn't posted, contact National Grid customer service.
Can I change my automatic payment date or amount?
You can change the date anytime by logging in and editing your autopay settings. The amount is set to your full bill each month, so it adjusts automatically. You can pause or cancel autopay at any time without penalty.
What happens if I overpay my bill?
If you pay more than you owe, the extra amount becomes a credit on your account. National Grid will explore it to your next bill, or you can request a refund by calling customer service.
