How to Log In to Your National Grid Bill Pay Account

Where to find the National Grid login page

National Grid's bill pay login is located at nationalgridus.com. On the homepage, look for a link labeled "Pay My Bill" or "Login" — this is usually in the upper right corner or under a "Customer Service" section. Clicking it takes you to the login portal where you enter your account number and password.

If you have never logged in before, you will need to create an account first. National Grid calls this process "registering" rather than signing up. You can register on the same login page by selecting an option like "New User" or "Register Now." You will need your account number, which appears on your paper bill or in any recent National Grid correspondence.

National Grid serves different regions under slightly different names — National Grid USA, Niagara Mohawk, Massachusetts Electric, or Narragansett Electric, depending on your state. The login portal works the same way across all of them, but make sure you are on the correct regional website for your service area.

Key Takeaways

• The National Grid bill pay login is at nationalgridus.com, where you enter your account number and password.
• New users must register first by providing their account number, which is printed on their paper bill.
• You can pay your bill, view your balance, and set up automatic payments once you are logged in.
• If you forget your password, use the "Forgot Password" link on the login page to reset it using your email address or account number.
• National Grid's website works on phones and computers, so you can log in from anywhere you have internet access.

What information you need to log in

To log in for the first time, gather your account number before you start. This number is on your paper bill, usually near the top or in a box labeled "Account Number" or "Service Account Number." It typically looks like a series of numbers and may include letters. Do not confuse it with your meter number or service address — the account number is what National Grid uses to identify your bill.

When you register, you will also create a username and password of your own choosing. The username can be your email address or a custom name you make up. The password should be something you can remember but that is not obvious — National Grid recommends mixing uppercase and lowercase letters, numbers, and symbols. Write it down somewhere safe, or use a password manager if you have one.

After registration, you will receive a confirmation email. Check your inbox and spam folder both — sometimes the confirmation lands in spam by mistake. Click the link in that email to set up your account. Only then can you log in and pay your bill.

Steps to pay your bill after logging in

Once you are logged in, the dashboard shows your current balance and due date. To pay right away, look for a button labeled "Pay Now," "Make a Payment," or "Pay My Bill." Click it and you will see options for how much to pay — you can pay the full balance, a partial amount, or a different amount you choose.

National Grid accepts payment by bank account (ACH transfer), debit card, or credit card. Bank account payments usually have no fee and take one to two business days to process. Debit and credit card payments process faster but may include a fee — National Grid's website will show you the fee amount before you confirm the payment.

After you choose your payment method and amount, review the details on the confirmation screen. Make sure the due date, amount, and account number are correct. Then click "Confirm" or "Submit Payment." You will see a confirmation number on the next screen — write this down or take a screenshot. National Grid will also email you a receipt.

Setting up automatic payments

If you want National Grid to withdraw your payment automatically each month, you can set this up in your account settings. Log in, then look for a menu option called "Autopay," "Automatic Payments," or "Recurring Payments." Click it and choose the amount you want to pay each month and the day you want it to come out of your account.

Automatic payments must come from a bank account — you cannot use a credit or debit card for recurring payments. National Grid will ask you to provide your routing number and account number. These are the same numbers on the bottom left of your checks. You can stop automatic payments at any time by logging back in and turning off the setting.

Many people set automatic payments for the full bill amount, so they never have to think about it. Others set it for a fixed amount slightly less than their average bill, then pay the remainder manually when the bill arrives. Both approaches work — choose whatever fits your budget.

What to do if you forget your password

On the National Grid login page, look for a link that says "Forgot Password" or "Forgot Username." Click it. National Grid will ask you to enter either your account number or the email address you used when you registered. You will then receive an email with a link to reset your password.

Click the link in that email and you will be taken to a page where you can create a new password. Make sure you are using the same email account you registered with — if you registered with one email and are now checking a different one, you will not see the reset email. If you cannot find it, check your spam folder.

If you do not remember your email address or account number, or if you do not receive the reset email after waiting 10 minutes, contact National Grid's customer service by phone. The number is on your paper bill. A representative can verify your identity and help you regain access to your account.

Troubleshooting common login problems

Account locked after too many login attempts: If you enter the wrong password several times in a row, National Grid will lock your account temporarily for security. Wait 15 to 30 minutes, then try again. If it stays locked, use the "Forgot Password" link to reset it.

Login page will not load: Try clearing your browser's cache and cookies, then refresh the page. If you are using an older browser, try a newer one like Chrome or Firefox. National Grid's website works best on current versions of major browsers. If the page still will not load, the website may be down for maintenance — try again in an hour.

You registered but cannot log in: Check your email for the confirmation message from National Grid. If you did not receive it, log back into the registration page and request a new confirmation email. You cannot log in until you click the confirmation link.

Payment went through but your bill still shows a balance: This is normal. Payments take one to two business days to post to your account. Check back in a few days and the balance should update. If it does not, contact National Grid to confirm the payment was received.

Viewing your bill and payment history

After you log in, you can see your current bill and all past bills. Look for a section called "Billing," "My Bills," or "Bill History." Click on any month to view the charges, your usage, and a breakdown of what you were charged for. This is useful if you want to understand why your bill went up or down.

You can also see every payment you have made. This section is usually called "Payment History" or "Account History." It shows the date you paid, the amount, and the payment method. If you need a record of a payment for your records or taxes, you can print or read this page.

National Grid also lets you read your bills as PDF files. This is helpful if you want to keep copies for your records or if you need to share your bill with someone else — for example, a landlord or a government program. Look for a read button or link next to each bill.

Frequently Asked Questions

Can I pay my National Grid bill without logging in?

Yes. National Grid accepts payments by phone, mail, and in person at payment centers. You can also pay through their automated phone system without speaking to a representative. The account number on your bill is all you need. However, logging in online is usually the fastest way to pay and gives you an when ready confirmation number.

Is it safe to enter my bank account information on the National Grid website?

National Grid's website uses encryption to protect your information, the same technology banks use. Your bank account and payment details are not stored in a way that lets National Grid withdraw money without your permission. If you are still uncomfortable, you can pay by debit or credit card instead, though there may be a fee.

What if I pay online but my bill is not marked as paid right away?

Online payments take one to two business days to process, depending on your payment method. Bank account payments are slower than card payments. Your bill will update once the payment clears. If more than three business days have passed and your account still shows the old balance, contact National Grid with your confirmation number.

Can I change my password after I log in?

Yes. Look for "Account Settings," "Security," or "Change Password" in your account menu. Click it and enter your current password, then create a new one. You will need to log in again with your new password the next time you visit.

What should I do if I see charges on my bill that I do not recognize?

Log in and view your detailed bill to see what each charge is for. National Grid breaks down charges by service type — electricity, gas, delivery, taxes, and fees. If you still do not understand a charge, contact National Grid's customer service. They can explain what it is and whether it is correct.
