The fastest way to pay Eversource is through their online account portal or mobile app, which process payments the same day you submit them

Eversource operates in Connecticut, Massachusetts, and New Hampshire. The payment method you choose affects when your payment posts and whether you pay a fee. Online and phone payments through Eversource directly are free and typically post within one business day. Mailed checks take 7 to 10 business days to arrive and clear. Third-party payment services charge convenience fees that Eversource does not charge themselves.

Before you pay, have your account number ready — it appears on your bill in the upper right corner. You will also need your service address or zip code to look up your account if you do not have the bill in front of you.

Key Takeaways

  • Eversource's website and mobile app let you pay for free and see your payment post the same business day, with no convenience fee.
  • Phone payments to Eversource's automated system are free, but speaking to a representative may involve a wait during peak hours.
  • Mailed checks should be sent to the address on your bill and take 7 to 10 business days to post, so plan ahead if your due date is near.
  • Third-party payment platforms like PayPal or your bank's bill pay service may charge fees that Eversource itself does not.

Paying online through your Eversource account

Go to eversource.com and select "Pay My Bill" or "Login" depending on whether you have already set up an online account. If you do not have an account, you can create one using your account number and service address. The setup takes about five minutes and you only do it once.

Once logged in, select the amount you want to pay — you can pay the full balance, a partial amount, or set up a recurring automatic payment. Choose your payment method: bank account (ACH transfer) or debit card. Bank account payments are free. Debit card payments are also free when you pay through Eversource directly, though some banks may charge their own fees on your end.

After you submit, you will see a confirmation number on screen. Save or screenshot it. The payment posts to your account the next business day. If you pay after 5 p.m. Eastern time on a weekday, or anytime on a weekend or holiday, it posts the following business day.

Paying through the Eversource mobile app

Download the Eversource app from the Apple App Store or Google Play Store. Log in with the same username and password you use on the website, or create a new account if you have not already. The app shows your current balance, due date, and payment history in one view.

Tap "Pay Now" or "Make a Payment" and enter the amount. Select your payment method — bank account or debit card — and confirm. You will receive a confirmation number immediately. Payments submitted through the app post on the same timeline as website payments: the next business day if submitted before 5 p.m. Eastern, or the business day after that if submitted later or on a weekend.

Paying by phone without speaking to a representative

Call Eversource's automated payment line at 1-800-752-6633 (Connecticut and Massachusetts) or 1-800-662-7764 (New Hampshire). Have your account number and bank account or debit card information ready. The system will confirm your account, ask how much you want to pay, and process the payment without connecting you to a person.

Automated phone payments are free and post the next business day, the same as online payments. The call typically takes 3 to 5 minutes. This option works 24 hours a day, 7 days a week, including holidays.

Paying by phone with a customer service representative

If you prefer to speak with someone or have questions about your bill, call the same numbers above and stay on the line instead of selecting the automated payment option. Wait times vary by time of day — mornings and early afternoons are usually shorter, while late afternoons and evenings can have 15- to 30-minute waits, especially during winter months when call volume is high.

A representative can take payment over the phone using your bank account or debit card. They can also answer questions about your balance, due date, or billing history. Payments made through a representative post on the same schedule as automated payments: the next business day if submitted before the cutoff time.

Paying by mail

Write a check or money order payable to Eversource. Do not send cash. Include your account number on the check. Mail it to the address printed on your bill — the address changes depending on which state you are in, so always use the one on your current statement.

Mail payments take 7 to 10 business days to arrive and post. If your due date is within two weeks, do not rely on mailing a check — use online, phone, or app payment instead. If you are mailing a payment and want to confirm it arrived, log into your online account after 10 business days and check your payment history.

Avoiding late fees and service interruption

Your due date appears on your bill. If you do not pay by that date, Eversource charges a late fee — the amount varies by state but is typically a percentage of your balance. After 30 days past due, Eversource may issue a disconnection notice. After 45 days past due in most cases, they can shut off your service.

If you are having trouble paying, contact Eversource before your due date. They offer budget billing plans that spread your annual costs into equal monthly payments, and hardship programs for customers facing financial difficulty. These programs do not erase what you owe, but they can make payments more manageable and prevent disconnection while you catch up.

Frequently Asked Questions

Does Eversource charge a fee to pay my bill online?

No. Eversource does not charge a fee for online, app, or phone payments made directly through their website or customer service line. If you use a third-party payment service like your bank's bill pay or PayPal, that service may charge a convenience fee, but Eversource itself does not.

How long does it take for a payment to show up on my account?

Online, app, and phone payments post the next business day if you submit them before 5 p.m. Eastern time on a weekday. Payments submitted after 5 p.m. or on weekends and holidays post the following business day. Mailed checks take 7 to 10 business days.

Can I set up automatic payments so I do not have to pay every month?

Yes. Log into your online account, go to "Billing" or "Payment Settings," and select "Automatic Payment" or "Recurring Payment." You can choose to pay the full balance, a fixed amount, or a percentage each month on a date you select. You can change or cancel automatic payments anytime.

What should I do if I cannot pay my bill on time?

Contact Eversource before your due date. They offer budget billing, which spreads your annual costs into equal monthly payments, and hardship programs for customers facing financial difficulty. Call the customer service number on your bill or log into your online account to explore these options.

Can I pay someone else's Eversource bill?

Yes, but you will need their account number and service address. You can pay through the website, app, or phone line. The payment posts to their account. If you are paying regularly for someone else, ask them to add you as an authorized user on their account so you can manage payments directly.
