What National Grid is and where to send your payment

National Grid is the company that delivers electricity and natural gas to homes and businesses across New York, Massachusetts, and Rhode Island. When you receive a bill from National Grid, you are paying for the energy delivered to your address, not for the company's services themselves — the delivery charge and the energy charge are separate line items on your statement.

Your payment goes to National Grid's billing department, not to a third party. The company operates regional divisions: National Grid USA (which handles New York and Massachusetts) and National Grid Rhode Island. Your bill will show which division serves your account based on your service address.

National Grid accepts payments through several methods, and the fastest routes depend on whether you want to pay online, by phone, or by mail. Each method has different processing times, so choosing the right one matters if your bill is due soon.

Key Takeaways

  • National Grid bills for electricity and natural gas delivery in New York, Massachusetts, and Rhode Island, and you pay the company directly.
  • Online payments through the National Grid website or mobile app typically post within one business day, while mail payments take 7 to 10 days.
  • Phone payments are processed when ready but may carry a fee depending on the payment method you use.
  • If you cannot pay your full bill, National Grid offers budget billing and hardship programs that spread costs over time or reduce what you owe.
  • Late payments trigger a reconnection fee and may result in service disconnection after 30 days of non-payment.

Paying online through the National Grid website or app

The fastest way to pay National Grid is through their official website or mobile app. Go to nationalgridus.com (for New York and Massachusetts) or nationalgridri.com (for Rhode Island). You will need your account number, which appears on your bill, and your online account login. If you do not have an online account yet, you can create one by entering your account number and service address.

Once logged in, select "Pay My Bill" and choose your payment method: bank account (ACH), debit card, or credit card. Bank account payments are free and post within one business day. Debit and credit card payments may carry a fee — National Grid charges a percentage of the payment amount, typically between 2 and 3 percent, though this varies. The website will show you the exact fee before you confirm.

The National Grid mobile app offers the same payment options and speed. You can also set up automatic recurring payments so your bill is paid on the same date each month without you having to log in again. Automatic payments reduce the risk of missing a due date.

Paying by phone

You can pay National Grid over the phone by calling their customer service line. For New York and Massachusetts, call 1-800-752-6633. For Rhode Island, call 1-800-322-3223. Have your account number and payment method ready — the company accepts debit cards, credit cards, and bank account information.

Phone payments are processed when ready, so your payment is recorded the same day you call. However, phone payments typically carry a fee unless you pay from a bank account. Credit and debit card payments over the phone usually cost 2 to 3 percent of the amount paid. Ask the representative for the exact fee before you provide your card information.

National Grid's phone lines are open during business hours and some evenings. Wait times can be long during peak billing periods, so calling early in the day or mid-week may be faster.

Paying by mail

You can mail a check or money order to National Grid. Your bill statement includes a payment coupon with the mailing address for your region. Do not send cash through the mail. Write your account number on the check or money order so the payment is matched to your account correctly.

Mail payments take 7 to 10 business days to reach National Grid's processing center and post to your account. If your bill is due in fewer than 10 days, mailing a payment risks a late fee. For this reason, mail is the slowest option and should be used only if you have time before the due date.

Keep a copy of the payment coupon or take a photo of your check before mailing it. If your payment does not appear on your account within 10 business days, contact National Grid with your check number and mailing date so they can locate it.

What happens if you cannot pay the full amount

National Grid offers budget billing, which spreads your annual energy costs evenly across 12 months so your bill is the same amount each month. This helps if your winter heating bills are much higher than summer bills. You can request budget billing through your online account or by calling customer service. National Grid recalculates your budget amount once a year based on your actual usage.

If you are struggling to pay your bill, National Grid has a hardship program for customers with low income or temporary financial difficulty. The program may reduce your bill, extend your payment important date, or waive late fees. To learn about hardship options, call the number on your bill and ask to speak with a representative about payment information. You may need to provide proof of income or documentation of your hardship.

Some states also offer energy information programs through community action agencies or local government. These programs pay part or all of your National Grid bill if you meet income requirements. You can search for programs in your area through the National Energy information Referral (NEAR) project at neada.org or by calling 211.

Late payments and reconnection fees

National Grid bills are typically due 20 to 25 days after the bill date. If you do not pay by the due date, a late fee is added to your account — the amount varies by state but is usually a percentage of your bill or a flat fee. Your bill will show the exact late fee amount.

If your account remains unpaid for 30 days after the due date, National Grid may disconnect your service. Before disconnection, the company sends a notice warning you of the date service will be shut off. If your service is disconnected, you must pay the full past-due balance plus a reconnection fee to have service restored. Reconnection fees vary by state and region but typically range from $50 to $150 or more. Reconnection may take one to three business days after payment is received.

If you receive a disconnection notice, contact National Grid when ready. Even if you cannot pay the full amount, the company may negotiate a payment plan or connect you with hardship resources before shutting off service.
