Thankyou for the guide - very helpful
The situation is as below - pretty much as the example on the guide which is handy.
Upon entering the car park, the driver found a space, parked up, and went for their appointment. The appointment ran over, and when they left the car park they had exceeded the maximum parking period. On 20th Nov 24, I, the registered keeper, received a PCN through the post.
Below is the link for the LoC

Many thanks
