UI's authorized payment agents are conveniently located throughout our service territory. Once you make payment on your account, it is not necessary to call in your payment and receipt information as this information is automatically posted to your account within one hour. However, making your payment on the “Due Date” at an authorized payment agent may not post until the following business day. Please pay your bill before the due date to avoid late payment charges or service interruption.
