If you need to apply for service at an already constructed commercial building,please contact NBU Customer Service Representatives at (830) 629-8400 or (830) 606-2074 (San Anotnio metro), and an application can be sent to you to fill out and return by fax or mail. Our fax number is (830) 629-2119. NBU will calculate the average of the past 12 months utility bills and multiply that amount by two to determine the deposit. Half of that amount will be due up front and the remaining balance will be added to your utility bill in one installment. In addition to the application, you will also need to provide us with your social security number and a copy of your driver's license.

Administrative fee

An administrative fee of $45 will be charged and added to your first month's bill. If you have both electric and water service, that fee will be split between the services at a cost of $22.50 each. If you only have one of these services, the total fee will be $45.
