Challenge a PCN online
If you are challenging multiple PCNs, please include all CU reference numbers in the challenge section of your PCN form.
The challenge form times out after 20 minutes. We recommend you write your comments offline and cut and paste them in to the form.
Challenges we can't accept
If your vehicle has been removed, you will need to contact the car pound directly and pay for its release. We will not accept a challenge for the removal PCN until your vehicle has been released.
If your PCN has reached Warrant stage, you will need to contact the relevant bailiff agency to pay the PCN amount and any additional bailiff fees.
What happens next?
Once you have submitted your challenge, you will receive a confirmation email. If you haven't received it, please check your spam folder.
You cannot challenge by phone. All challenges must be made in writing, in line with parking legislation.
Please note, if you can't view the CCTV PCN footage it may be that you are attempting to view it on a MAC or with IOS. Unfortunately, the footage can only be viewed via a windows operating system.
