Setting up automatic payments to avoid late fees
Autopay is the simplest way to ensure your bill is paid on time every month without having to remember the due date. Log into your National Grid account online, go to the payment settings, and select the option to set up automatic payments from your bank account or card.
You can choose the payment date — most people pick the due date shown on their bill, but you can select any date that works with your pay schedule. National Grid will deduct the amount due automatically each billing cycle. If your bill amount varies month to month (which it does for most customers), the system will charge the actual amount due, not a fixed number.
If you need to pause or cancel autopay, you can do that anytime through your account. There is no penalty for stopping automatic payments, and you can switch back to manual payment whenever you want.
Understanding your bill due date and late payment fees
Your bill due date appears on the front of your statement, usually 20 to 25 days after the bill is issued. If you pay after that date, National Grid charges a late fee. The fee amount depends on your bill total, but it is typically a percentage of what you owe.
If your payment arrives after the due date but before National Grid disconnects your service, you will owe the late fee in addition to your regular bill. Disconnection for non-payment usually happens 30 to 45 days after the due date, though National Grid sends notices before that happens. If you are facing a disconnect, call 1-800-752-6633 immediately — the company has hardship programs that may help you avoid service loss.
Paying by mail carries timing risk because the postal service can delay delivery. If you are cutting it close to the due date, pay online or by phone instead to ensure the payment posts on time.
What to do if you cannot pay your full bill
If you cannot pay the full amount by the due date, contact National Grid before your account falls behind. The company offers budget billing, which spreads your annual energy costs into equal monthly payments so you avoid large winter or summer bills. You can request budget billing through your online account or by calling 1-800-752-6633.
National Grid also has hardship programs for customers facing financial difficulty. These programs may allow you to defer part of your bill, extend your payment deadline, or reduce your monthly payment temporarily. To learn about hardship options, call the number above and ask to speak with a representative about your situation — you do not need to wait until your account is disconnected.
If you are a low-income household, you may also be may be able to access for the Low Income Home Energy Assistance Program (LIHEAP), which is run by the state of Massachusetts. LIHEAP can pay part or all of your heating bill directly to National Grid. Contact your local community action agency or call 1-866-534-4323 to learn whether you meet the income limits.
Checking your account balance and payment history online
Log into your National Grid account at nationalgridus.com to see your current balance, recent payments, and billing history. The online portal shows when each payment posted and how much you paid, which is useful if you need to verify a payment or dispute a charge.
You can also see your estimated next bill amount and due date, which helps you plan ahead. If you notice a payment did not post within a few days of sending it, check your account online first — sometimes there is a processing delay. If the payment still does not appear after 10 business days, call National Grid to confirm it was received.
Paying by phone, mail, or third-party locations
Phone payments are processed immediately when you call 1-800-752-6633 with a debit or credit card. Have your account number and card information ready. The system will confirm the payment amount and date before charging your card. There is no fee for paying by phone.
Mail payments should be sent to the address on your bill. Write your account number on the check or money order so National Grid can match the payment to your account. Mail takes longer than other methods, so allow at least 10 business days for delivery and posting.
Some grocery stores and pharmacies in Massachusetts accept National Grid payments as a third-party service. These locations charge a small fee (usually $1 to $3) on top of your bill amount. Ask at the customer service desk whether they accept National Grid payments before you go.
Resolving payment disputes and billing errors
If you believe a charge on your bill is wrong, contact National Grid within 30 days of receiving the bill. Call 1-800-752-6633 or use the dispute option in your online account. National Grid will investigate the issue and respond within 30 to 45 days.
While a dispute is being investigated, you still owe the undisputed portion of your bill by the due date. If you do not pay the undisputed amount, late fees and disconnection risk still apply. Pay what you know is correct, and dispute only the amount you believe is wrong.
Keep copies of your bills, payment confirmations, and any correspondence with National Grid about the dispute. If you paid by check, keep the cancelled check as proof. These documents help if the dispute takes longer than expected or if you need to escalate the issue.
