The fastest way to pay National Grid is through their online portal, which lets you pay immediately from your bank account or credit card without calling or visiting an office.
National Grid operates in New York and Massachusetts. To pay online, you log into your account on the National Grid website, enter your bill number or service address, and choose your payment method. The payment posts within one to two business days. You can also set up automatic payments so the bill comes out on the same day each month, which stops late fees from catching you by surprise.
If you do not have an online account yet, you will need to create one first. This takes about five minutes and requires your bill number, which appears on your paper bill or in any email from National Grid.
Key Takeaways
- You can pay your National Grid bill online through their website using a bank account or credit card, and the payment posts within one to two business days.
- Setting up automatic payments prevents late fees and removes the need to remember your due date each month.
- You need your bill number to create an online account, which you can find on your paper bill or in National Grid emails.
- If you cannot pay the full amount, contact National Grid about payment plans before your bill becomes overdue.
Creating your National Grid online account
Go to the National Grid website and select "Log In" or "Create Account" — the button location varies slightly depending on whether you are a gas or electric customer. You will be asked for your bill number, which is a unique identifier printed on your bill. If you cannot find it, you can also use your service address instead.
After you enter your bill number or address, National Grid sends a verification code to the email or phone number on file. Enter that code to confirm your identity. Once verified, you create a username and password. Write these down somewhere safe, because you will use them every time you log in to pay.
The account creation process takes about five minutes. You do not need to do anything else — your account is active immediately and you can pay your next bill right away.
Paying a bill through your online account
Log in with your username and password. Your current bill amount and due date appear on the dashboard. Click "Pay Now" or "Make a Payment" — the exact wording depends on your region and whether you are a gas or electric customer.
You will see a payment form asking for the amount you want to pay. You can pay the full amount due, a partial amount, or more than you owe (the extra goes toward your next bill). Choose your payment method: bank account (which is free and takes one to two business days) or credit or debit card (which posts the same day but may charge a fee). Enter the payment details and confirm.
National Grid sends a confirmation email with your payment reference number. Keep this for your records. The payment posts within one to two business days if you use a bank account, or the same day if you use a card.
Setting up automatic payments to avoid late fees
Automatic payments mean National Grid withdraws your bill amount from your bank account on the same day each month, so you never miss a due date. This is the easiest way to stay current, especially if you have trouble remembering when bills are due.
Log into your account and look for "Autopay," "Automatic Payment," or "Recurring Payment" in the settings or billing section. You will enter your bank account number and routing number (both appear on the bottom left of your checks). Choose the day of the month you want the payment to come out — many people pick the day after they get paid.
You can change or cancel automatic payments anytime through your account. If your bill amount changes, National Grid automatically withdraws the new amount, so you do not have to update anything manually.
What to do if you cannot pay the full amount
If you cannot afford the full bill, do not ignore it. Contact National Grid before your due date and ask about a payment plan. Most utilities offer plans that let you spread the balance over two to four months, and they will not charge a late fee if you stick to the plan.
You can call National Grid's customer service number (on your bill) or ask about payment plans through your online account. Have your bill number ready. Be honest about how much you can pay each month — the company will work with you to set a realistic schedule.
Some states also offer bill assistance programs for households that struggle to pay. National Grid's website has information about programs in your area, or you can call 211 to find local resources.
Payment methods and fees
National Grid accepts bank account payments (free, one to two business days), credit cards (may charge a fee, same-day posting), and debit cards (may charge a fee, same-day posting). Some regions also accept checks by mail, though this is slower and requires you to write your account number on the check.
The fee for credit and debit card payments varies by region and payment processor. National Grid's website shows the exact fee before you confirm your payment, so you know the cost upfront. Bank account payments never have a fee.
If you pay by check, mail it to the address on your bill at least one week before the due date. National Grid's processing time is slower for mailed checks, so paying online is faster and safer.
Troubleshooting common online payment problems
If you forgot your password, click "Forgot Password" on the login page. National Grid sends a reset link to your email. If you do not receive it within a few minutes, check your spam folder or try again with the email address on your account.
If your payment is rejected, the most common reasons are a wrong bank account number, insufficient funds, or an expired card. Check that your bank account or card information is correct and that you have enough money in the account. If the problem persists, call National Grid's customer service line — they can process the payment over the phone or help you fix the account information.
If you see a payment on your bill that you did not make, contact National Grid immediately. Provide your payment reference number (from your confirmation email) and the date the payment was made. National Grid can investigate and reverse unauthorized charges.
Frequently Asked Questions
How long does it take for an online payment to show up on my bill?
Bank account payments take one to two business days. Credit and debit card payments post the same day. Once the payment posts, your bill balance updates and your next due date adjusts accordingly.
Can I pay someone else's National Grid bill online?
You can pay a bill if you have the account number and the account is registered to you or you are an authorized user. If you want to pay for a family member or friend, ask them to add you as an authorized user through their account settings, or contact National Grid's customer service to arrange it.
What happens if I set up automatic payments and then move?
Contact National Grid before you move to close your old account and open a new one at your new address. Your automatic payment will stop when the old account closes. You will need to set up automatic payments again on your new account.
Is it safe to pay my National Grid bill online?
National Grid uses encryption and security measures to protect your payment information. Your bank account and card details are not stored on the website — they are processed through a secure payment gateway. Never share your login credentials with anyone, and always log out after paying.
Can I get a receipt for my online payment?
Yes. National Grid sends a confirmation email immediately after you pay, and you can view your payment history anytime by logging into your account. Print the confirmation email or take a screenshot if you need a paper record.
