If you've signed up for new service recently, you will need to wait one billing cycle (approximately 30 days) for your account information to be available online. 

If you are an existing customer, please call us toll-free and we'll assist you.

If you or a family member uses electrically-operated life support systems, we encourage you to notify Unitil in advance of any outages by submitting our Physician’s Certification Form found here via email, fax or mail. Once we receive this form, your account will be noted and we will include a notification to you in the event that we anticipate adverse weather or a scheduled outage which may result in a power outage.

Generally, your budget billing monthly payment amount will change once or twice within the year. These adjustments are made to your payment amount to prevent you from having a large amount due or credit balance at the end of the program year. Prior to our changing your payment amount, you will be notified by mail of the new amount, which will appear on your next bill. The decision to change your payment amount is based on several factors. While we try to limit the number of adjustments, your payment amount may change when:

• The price of electricity and/or natural gas changes
• Warmer or colder temperatures mean you will use more or less energy to heat or cool your home
• Your monthly usage has changed compared to prior usage history that was used for calculating your payment amount
• You have purchased or replaced appliances

To mail in a payment, please address it to:

P.O. Box 981010

A number of payment locations are conveniently located throughout our MaineMassachusettsNew Hampshire service area.

Please be aware that some locations may require a bill in order to make a payment or process a security deposit. Federal requirements limit the maximum payment amount at $2,500 per transaction. Use only authorized payment agents to facilitate timely payment posting!

Many of our customers pay their bill directly to us or use a payment agent that we've authorized to collect customer payments. However, some customers have used bill payment services that do not have any arrangements with us to process payments. We cannot ensure that payments made through one of these unauthorized bill payment services will be forwarded to us in a timely manner or even ensure that payment will be forwarded at all.

To protect yourself and your utility service, be sure to follow these steps:

• Use caution when making your payment through a third-party bill payment service that is not authorized by Unitil.
• Be sure to bring both portions (top and bottom) of your bill or provide your 14-digit Unitil account number.
• The payment agent might charge a service fee for each transaction. Check your local phone directory and contact the payment agent for specifics. Most importantly, always keep your receipt.

If you have received a termination notice, call us immediately at 800-852-3339 for Capital-region electric service, 800-582-7276 for Seacoast-region electric service or 866-933-3820 for New Hampshire gas service.  If you are calling on the date of termination, we cannot guarantee your service will not be shut off.

Avoid shut-off by taking these steps:

Late Charges: Your payment is credited to your account on the date Unitil receives the payment. If payment is not received by the due date of your current bill, a late payment charge will be added to your account. The late payment charge for gas service is 1%. The late payment charge for residential electric service is 1%. The late payment charge for commercial electric service is 1.5%.

Your meter could be one of several models we use in our service areas. Digital and odometer displays are the most straightforward to read because they present your energy usage directly; dial meters can be a little more difficult. Click here to learn how to read your dial meter.

There are two primary reasons you would see differences in these values.

First, the customer receives their services through a primary metered service, providing your facility with a higher voltage (typically 13.8 kV or 34.5 Kv). Due to the reduction of equipment required to provide this service, we extend a discount.

The second, less likely reason for the difference between the two values could be attributed to a customer’s substantial load variations throughout the year.  For instance, our NH G-1 (Large General Service Rate) customers could fall under our ratchet demand clause for large services, where customers are charged 80% of their highest demand over the last 13 months to compensate for additional resources required to serve those loads. Most customers are not affected by this situation, however.  

Typically a day or so prior to when you would normally receive them in the mail. You will receive an email reminder if your bill goes unviewed for more than 4 days after your initial receipt.

Your bill can be paid by selecting the "Pay" button. The payment date is automatically populated to match the due date and the amount on your bill. You may change the payment date or amount by highlighting the appopriate fields and entering the new information.

Our e-bill program is offered through our partner, Checkfree. You can call Checkfree's support team toll-free at 800-564-9184.
