Notice and timing
How delinquency is handled
Grace period after the due date
Approximately 20 days after the billing date; the GUC deposits-and-fees page says bills are due upon receipt and become past due 20 days after billing.
Late-fee calculation
A 1% late fee is assessed on the past-due amount when the balance remains unpaid for approximately 23 days from the bill date. GUC also lists a $25 returned-check fee and gives seven days written notice after a returned item to pay the returned amount plus the service charge.
Disconnection timeline
GUC states customers should pay within approximately 30 days of the billing date to ensure continued service. If service is disconnected for nonpayment, restoration requires $37.80 during regular business hours or $70.20 after regular hours, in addition to the past-due balance and other applicable charges.
