26 Del. Admin. Code § 3002-4.0
All covered utilities shall inform all of their customers of the availability of any third party notification program offered by the utility, whereby the customer can designate, in writing, a third person to receive notice of past due bills and written notice of termination of service. The third party so designated must indicate, in writing, willingness to receive such notice and shall not be held, in any way, liable to the utility by reason of acceptance of third party status.
No covered utility without a third party notice program, shall terminate service to a dwelling unit during the heating or cooling season without first having given the written notice required by § 3.1 and, in addition, having made actual contact on a face-to-face basis with an occupant over the age of 15 years of such dwelling unit, giving the minimum notice set forth in § 3.3.
If a covered utility adopts such a program, the utility shall take appropriate steps to see that all customers are aware of the existence of the third party notice program.
