National Grid's Online Payment Portal
National Grid operates separate online bill payment systems depending on which utility service you use and which state you're in. If you receive a National Grid electric or gas bill, you can pay online through the company's website by logging into your account or paying as a guest without creating an account. The payment goes through when ready, though it may take one to two business days to appear on your account record.
National Grid serves customers in Massachusetts, New York, and Rhode Island for electricity, and in Massachusetts and New York for natural gas. Each state's system works similarly, but you'll need to access the correct regional portal for your service area. You can find the right link by entering your zip code on the National Grid homepage, which directs you to your local utility company's site.
Payments made online are processed the same day if submitted before the cutoff time, typically around 5 p.m. Eastern Time on business days. Weekend and holiday payments are queued for processing the next business day. National Grid does not charge a fee for paying online through their website, though some third-party payment processors may add a convenience fee if you choose to use them instead.

Setting Up Your Online Account
Creating a National Grid online account is optional — you can pay as a guest every time — but an account lets you view your bill history, set up automatic payments, and receive email reminders. To create an account, visit your regional National Grid website and select "Create Account" or "Sign Up." You'll need your account number, which appears on your paper bill or in any recent correspondence from National Grid.
During account setup, you'll create a username and password, then verify your identity by answering security questions or confirming information National Grid has on file. The process takes about five minutes. Once your account is active, you can log in anytime to check your balance, view past bills, and update your contact information.
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 associated with your account. If you no longer have access to that email, you can call National Grid's customer service line for your region to verify your identity and regain access.
Paying as a Guest Without an Account
The guest payment option lets you pay your bill in minutes without logging in or creating an account. On your regional National Grid website, select "Pay as Guest" or "One-Time Payment." You'll enter your account number and zip code to locate your account, then review your current balance.
After confirming the amount you want to pay, you'll enter your payment method — debit card, credit card, or bank account. National Grid accepts Visa, Mastercard, American Express, and Discover for card payments. For bank account payments, you'll provide your routing number and account number. Guest payments are processed when ready, though the transaction may not show on your account for one to two business days.
Guest payments do not save your information for future use. If you pay this way regularly, creating an account or setting up automatic payments will save you time.
Automatic Payments and Recurring Billing
National Grid offers automatic payment options that deduct your bill from a bank account or charge a card on your due date each month. To set up automatic payments, log into your account, navigate to the payment settings or billing section, and select "Enroll in Automatic Payments." You'll choose your payment method and confirm the due date.
Automatic payments reduce the risk of late fees because the payment is scheduled before your due date. You can change or cancel automatic payments anytime through your account settings. If you need to stop a payment before it processes, contact National Grid at least three business days before your due date.
If you're on a budget billing plan — where National Grid averages your annual usage and charges you the same amount each month — automatic payments work the same way. The fixed amount will be deducted on your chosen due date.
Payment Methods and Processing Times
National Grid accepts multiple payment methods online: debit cards, credit cards, and bank account transfers. Debit and credit card payments are processed when ready when you submit them, though they may take one to two business days to post to your account. Bank account payments (ACH transfers) also process the same day if submitted before the cutoff, with posting typically within one to two business days.
If you pay by phone instead of online, National Grid charges a fee for credit card payments but not for bank account payments. Online payments through the National Grid website carry no fee regardless of payment method. Third-party payment services that appear in search results may charge convenience fees; these are not National Grid fees and are set by the third party.
If you need your payment to reach National Grid by a specific date to avoid a late fee, submit it at least one business day before your due date. Payments submitted on your due date may not post in time to prevent a late charge.
Troubleshooting Common Payment Issues
If your payment is declined, the most common reasons are an incorrect card number, an expired card, insufficient funds in your bank account, or a mismatch between the billing address on file and the address you entered. Check that your card details are correct and that your account has sufficient funds. If you're paying from a bank account, confirm that the account is active and has no holds or restrictions.
If you submitted a payment but it doesn't appear on your account after two business days, log into your account and check the payment history section. Payments sometimes show as "pending" before they post. If the payment still doesn't appear after three business days, contact National Grid customer service with your confirmation number (provided when you completed the payment) and they can investigate.
If you accidentally paid twice or paid the wrong amount, contact National Grid within a few days. They can often reverse a duplicate payment or adjust your account for an overpayment. Refunds are typically issued to your original payment method within one to two billing cycles.
Contacting National Grid for Payment Help
National Grid's customer service phone numbers vary by state and service type. You can find the correct number for your region by entering your zip code on the National Grid website. Massachusetts electric customers can reach National Grid Massachusetts at 1-800-322-3223. New York electric customers can reach Con Edison or Rochester Gas and Electric depending on their service area. Rhode Island customers can reach National Grid Rhode Island at 1-800-322-3223.
If you're having trouble with your online payment, customer service can walk you through the process or process a payment over the phone. They can also help if you need to set up a payment plan due to a large bill or financial hardship. National Grid offers budget billing and hardship programs in some cases, which customer service can explain.
You can also reach National Grid through their website's chat feature or by mail if you prefer not to call. Response times vary by method, but phone calls are usually answered within a few minutes during business hours.
