Free Traffic Legal Advice

Registered owner received a PCN via post (see link of images) on 11th March. Date of alleged contravention according to the letter was 20th February, and letter issued 5th March.

The driver of the vehicle parked in said carpark at 7.34am, and left at 12.38pm. The driver forgot to pay their parking until 8.39am, but did leave before the end time paid for. It may be important to note, that the driver paid for the parking via the RingGo app, incase this is pertinent to retrievable names on a payment list of some sort.

I am the registered keeper of the vehicle with the V5C and named on the letter received.
Im aware that cases in Northern Ireland are treated differently, however would like advice on how to proceed from here.
Would it be best for registered owner to submit an appeal or send any paragraphs I have seen on here etc or ignore all correspondence entirely?

I was not sure how to proceed as the driver paid for majority of the time, and may be identifiable through payment method used.

Any advice is appreciated. Thank you.

Thanks for that - the dates I thought were okay as it the issue date was within 14 days but thats good to know. I appreciate the help, is there any chance I could get a hand with rewording it appropriately? Feel clueless which I guess is how they make their moneh. Thanks either way!

Did you appeal as advised?
Or ignore?
In either case, ignore Debt Recovery Plus.
