A PCN also needs to include certain information to ensure its validity – if any of the following information is missing, you should consider appealing:

- Information on how to pay the charge and who to pay it to.
The PCN should also inform you of the 28-day deadline for paying the fine, and the 14-day deadline that can spare you half of the bill.
