Bailiffs must provide evidence of their identification upon request by the debtor, as a well as sight of the warrant providing them with authority to enter. They must also legally give the debtor an enforcement notice seven days before they visit. In contrast, private sector debt collectors can chase a debtor to pay what is owed to a creditor, but they cannot levy distress. Debt collectors are not allowed to pretend to be a bailiff. Debtors can also check the register of certificated bailiffs if they are unsure about whether a bailiff is certificated or not.
