Per ICC regulations, the due dates for bills issued by Peoples Gas (and other Illinois regulated utilities) are:

  • 21 days after the billing date for residential accounts
  • 14 days after the billing date for non-residential accounts
  • 31 days for special accounts (customers with exceptional circumstances such as welfare or Social Security recipients)
  • 45 or 60 days for certain governmental accounts

If payment is not received by the due date, customers are normally charged a Late Payment Charge (LPC) of 1.5% of the unpaid bill before taxes (not inclusive of Supplier Charges).
