Convenient Payment Centers

Through Western Union, we offer the convenience of walk-in utility bill payment at a number of store locations.  When you wish to make a payment, simply bring your monthly bill and your payment in cash or check to one of these locations and allow 1 to 3 business days for the payment to be posted to your account. The store's representative will process your payment, transmit it to our processing system and will provide you with a receipt validating your payment.

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!

List of approved payment locations


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 begun using 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 us.
  • 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.
