Also just to add, the NtK arrived after a period of 28 days (april 15th) from the alleged contravention. Does that nullify the entire ticket? Or is the time period longer as a paper PCN was initially issued (marcg 15th)? I tried to understand the PoFa legislation but getting confused by the wording!
And another point (probably moot) - i was anticipaing the NtK to arrive at my previous address as i have not yet updated the V5c. I did update my DL however to my current address last year. I was under the impression the DVLA would only provide the details from the V5c, but looks like they've provided details from my license, is that an issue?
