National Grid's Online Payment Portal

National Grid customers can pay their bill through the company's website by logging into their account at nationalgridus.com. You will need your account number (found on your bill) and a password to access the portal. Once logged in, you can view your current balance, payment history, and make a one-time payment or set up automatic recurring payments.

The login process is straightforward: enter your account number in the username field, then your password. If you do not have an account set up yet, you can create one by selecting "Create Account" on the login page and following the registration steps. National Grid will ask for your account number, email address, and a new password during setup.

Payments made through the online portal are typically processed the same business day if submitted before 5 p.m. Eastern Time. The system accepts payments via bank account (ACH transfer) or debit card. Credit card payments are not accepted through the National Grid website, though some third-party payment processors may offer that option for an additional fee.

Key Takeaways

  • Log in at nationalgridus.com using your account number and password to view your bill and make payments.
  • You can set up automatic monthly payments through the online portal so you do not have to log in each month.
  • Same-day processing is available for payments submitted before 5 p.m. Eastern Time on business days.
  • The portal accepts bank account transfers and debit card payments, but not credit cards.
  • If you forget your password, use the "Forgot Password" link on the login page to reset it using your email address.

Creating and Managing Your Account

Setting up an online account with National Grid takes about five minutes. Go to nationalgridus.com and click "Create Account." You will need your account number (the reference number on your bill), an email address, and a phone number. National Grid will send a verification code to your email; enter that code to confirm your identity and complete registration.

Once your account is active, you can update your contact information, view 24 months of billing history, and read past bills as PDF files. The portal also shows your current usage and estimated next bill amount. If you have multiple properties served by National Grid, you can link all accounts to a single login and switch between them without logging out.

If you forget your password, click "Forgot Password" on the login page and enter your account number and email address. National Grid will send a password reset link to your email within a few minutes. The reset link expires after 24 hours, so complete the process promptly if you need to regain access.

Setting Up Automatic Payments

Automatic payments remove the need to log in and pay manually each month. From your account dashboard, select "Autopay" or "Automatic Payments" and choose your payment method: bank account or debit card. You will need to provide your routing number and account number for bank transfers, or your debit card number and expiration date for card payments.

National Grid offers two autopay options: pay the full bill amount each month, or pay a fixed amount you set yourself. If you choose a fixed amount, you remain responsible for any balance that exceeds that payment. Most customers choose full-bill autopay to avoid carrying a balance month to month.

You can change or cancel autopay at any time through your account settings. Changes take effect on your next billing cycle. If you cancel autopay and forget to pay manually, National Grid will send you a past-due notice; paying within 10 days of that notice typically avoids service interruption, though timing varies by state and local rules.

Payment Methods and Processing Times

National Grid accepts two payment methods through its online portal: ACH bank transfers (direct debit from your checking or savings account) and debit cards. ACH transfers usually have no fee and process within one business day. Debit card payments may carry a small fee depending on your card issuer and are processed the same business day.

If you pay after 5 p.m. Eastern Time or on a weekend or holiday, your payment will be processed the next business day. National Grid does not accept credit cards through its website, though some third-party bill payment services (like your bank's bill pay feature) may process National Grid payments using a credit card for a fee.

You can also pay by phone by calling National Grid's customer service line (the number is on your bill) and providing your account number and payment method. Phone payments are processed the same day if made before 5 p.m. Eastern Time on a business day. Mail-in checks are also accepted; send them to the address listed on your bill, allowing 7 to 10 business days for processing.

Troubleshooting Login and Payment Issues

If you cannot log in, first check that you are using your account number (not your name) as your username. Account numbers are typically 10 to 12 digits and appear at the top of your bill. If you are still locked out, use the "Forgot Password" link to reset your credentials. If that does not work, contact National Grid customer service by phone or through the "Contact Us" page on their website.

If your payment is rejected, the most common reasons are an expired debit card, insufficient funds in your bank account, or a mismatch between the name on your account and the name on your payment method. Check that the name, account number, and routing number (for bank transfers) are entered correctly. If the problem persists, call customer service to verify your account details.

If you see a payment on your account that you did not make, contact National Grid when ready. Fraudulent activity is rare on utility accounts, but if your login credentials were compromised, the company can help you find your account and reverse unauthorized charges. Keep your password strong and do not share it with anyone.

National Grid Service Areas and Regional Differences

National Grid operates in New York, Massachusetts, and Rhode Island. The login process and payment portal are the same across all three states, but billing cycles, payment due dates, and late-payment policies vary slightly by state and local utility commission rules. Check your bill for your specific due date and any state-specific payment options.

Some National Grid customers in New York may also be served by subsidiary companies like Niagara Mohawk or Brooklyn Union Gas; these accounts use the same nationalgridus.com portal and login system. If you are unsure which company serves your address, check your bill or enter your zip code on the National Grid website.

Frequently Asked Questions

What if I do not have an email address to create an account?

You will need an email address to set up an online account, as National Grid uses it to verify your identity and send password reset links. If you do not have one, you can create a free email account through Gmail, Yahoo, or Outlook in a few minutes. Once you have an email address, return to nationalgridus.com and complete the registration process.

Can I pay my National Grid bill through my bank's bill pay service?

Yes. Most banks offer bill pay features that allow you to send a check to National Grid's mailing address on your behalf. This typically takes 7 to 10 business days. Some banks also offer electronic bill pay directly to utilities; check with your bank to see if National Grid is available through their system. Processing times and fees vary by bank.

What happens if I miss a payment important date?

National Grid will send you a past-due notice if your payment is not received by the due date. You typically have 10 days from that notice to pay before the company considers disconnecting your service. The exact grace period depends on your state and local regulations. If you receive a past-due notice, pay as soon as possible and contact National Grid if you need to discuss a payment plan.

Is my payment information find on the National Grid website?

National Grid uses encryption and security protocols to protect your login credentials and payment information. The website uses HTTPS (indicated by a padlock icon in your browser), which means data sent between your computer and National Grid's servers is encrypted. Do not share your password with anyone, and log out after each session, especially on shared computers.

Can I change my autopay amount or payment date?

Yes. Log into your account, go to the Autopay section, and update your payment amount or the date the payment should be deducted each month. Changes take effect on your next billing cycle. If you need to change the payment date for the current month, contact National Grid customer service by phone to make the adjustment manually.
