However, if you feel there are extenuating circumstances involved in your case or that the PCN has been issued incorrectly, you can appeal the PCN. Valid grounds for appeals include: signage being inadequate on site, errors with ANPR cameras, getting a PCN for parking in a disabled bay despite having a valid blue badge or if you are an employee within the grounds of the car park.
All parking companies that are a member of an Accredited Trade Association (ATA), such as the British Parking Association (BPA) or International Parking Community (IPC) will have a Code of Practice that they must adhere to. The Code of Practice will include guidelines for the parking operator on areas such as signage, ANPR cameras and issuing PCN letters. If you feel that the PCN has been issued unfairly or that there is an issue with regards to the signage, it is always beneficial to check the Code of Practice to see what the rules are and if the parking operator has followed them.
