PCN code 93: parked in car park when closed
What this contravention code means, and how to appeal it · Off-Street
Code 93 means the council or TfL recorded your vehicle as parked in car park when closed. If you paid but it wasn't recorded, or the car park's signage didn't make the terms clear, that's worth challenging.
Full description on the ticket: “Parked in car park when closed.”
Can I appeal this?
Yes. This is a statutory Penalty Charge Notice from a council or TfL, not a private charge, so you have a formal right to challenge it before it escalates into a Charge Certificate.
