Where to pay your Eversource gas bill

Eversource Energy (formerly Northeast Utilities) is the main gas supplier in Connecticut. You can pay your bill online through their website, by phone, by mail, or in person at a payment location. The fastest and most convenient method for most people is online through your Eversource account.

To pay online, log into your Eversource account at eversource.com using your account number and password. If you don't have an online account yet, you can create one for free. Once logged in, select "Pay My Bill" and choose your payment method — debit card, credit card, or bank account transfer. Online payments typically process within one business day.

If you prefer not to use the website, you can call Eversource's payment line at 1-800-286-2000 to pay by phone with a debit or credit card. There is no fee for paying by phone. Payments made before 5 p.m. on a business day are usually applied the same day.

Key Takeaways

  • Eversource's website (eversource.com) is the fastest way to pay — log in with your account number and pay by card or bank transfer with no fee.
  • Phone payments at 1-800-286-2000 process the same day if you call before 5 p.m. on a weekday, and there is no charge for this method.
  • Mail payments should be sent at least 10 days before your due date to arrive on time, and you should include your account number on the check.
  • Late fees apply if payment is not received by the due date shown on your bill, so set a reminder if you pay by mail.

Paying by mail or automatic withdrawal

If you prefer to mail a check, write your account number on the check and send it to the address printed on your bill. Mail payments take 7 to 10 days to reach Eversource, so send your payment at least 10 days before the due date to avoid a late fee. Do not send cash through the mail.

The easiest way to never miss a payment is to set up automatic withdrawal from your bank account. You can enroll in this service through your online Eversource account or by calling 1-800-286-2000. Eversource will deduct your bill amount on or shortly after your due date each month. There is no fee for automatic payments, and you can change or cancel the arrangement at any time.

Understanding your bill due date and late fees

Your bill shows a due date, usually 20 to 25 days after the bill is mailed. Payment is considered on time if Eversource receives it by that date. If you pay online or by phone, the payment posts immediately. If you mail a check, the postmark date does not matter — only the date Eversource receives it counts.

If your payment arrives after the due date, Eversource will add a late fee to your next bill. The amount varies but is typically a percentage of your bill or a flat fee, whichever is greater. If you know you will be late, call Eversource before the due date to discuss your options. Some customers may be able to arrange a payment plan or extension.

What to do if you cannot pay your full bill

If you cannot afford to pay your full bill by the due date, contact Eversource immediately at 1-800-286-2000. Do not wait until after the due date passes. Eversource offers payment plans that let you spread your bill over several months. You may also be able to defer part of your payment to your next bill.

Connecticut residents may also be may be able to access for the Connecticut Energy Assistance Program (CEAP), which provides grants to help with heating and cooling costs. This program is run by the Connecticut Department of Social Services and is separate from Eversource. You can learn more about CEAP through your local Community Action Agency or by calling 211.

Avoiding common payment mistakes

The most common mistake is not including your account number on a mailed check. Without it, Eversource may not know which account to credit, and your payment could be delayed. Always write your account number clearly on the check itself, not just on the envelope.

Another mistake is paying through a third-party bill payment service without checking the fee. Some banks and payment apps charge a fee to send money to utilities. Paying directly through Eversource's website or by phone costs nothing. If you use a third-party service, confirm the fee before you authorize the payment.

Do not assume that a payment made a few days before the due date will definitely arrive on time if you mail it. Mail can be delayed, and Eversource only counts the date they receive it. If you are close to the due date, use online or phone payment instead.

Finding your account number and bill information

Your Eversource account number appears on the front of your bill, usually in the upper right corner. You will need this number to pay by phone, set up automatic withdrawal, or create an online account. If you cannot find your bill, you can look up your account number on the Eversource website by entering your service address and last name.

Your bill also shows your current balance, the amount due, and the due date. If you have questions about charges on your bill or want to understand how your rate is calculated, you can call Eversource's customer service at 1-800-286-2000 and ask to speak with a representative. They can explain individual line items and answer questions about your service.
