Draft Appeal:
Dear Sirs,
On 8/11/23 I received PCN GD64190398 while loading in a marked bay.
I work for [Redacted] and we work with [Customers Name] supplying their [Technical Terms] equipment. On the date in question they encountered a catastrophic failure of some key hardware and as a result were struggling to trade.
I attended site to deliver a replacement [Piece of Kit] at 14:49 where I was observed by one of your Officers.
There was no clear and apparent signage limiting duration of loading, so once I had completed the delivery I left site, only to be told that I had exceeded five minutes and therefore was in breach of the laws. There are no time restriction signs in the area and as a result, I felt six minutes was an appropriate and fair period of time to be in a designated Loading Bay. I did not use my time parked there to complete any other tasks or to carry out any personal errands, merely to deliver the [Equipment]. You can see details of this [Equipment] as well as the manager of [The Site] signature verifying this attached.
I am happy to provide further authorisation of the work carried out from my employer if required.
Yours faithfully
[Me]
I must not have been clear about "further stuff". The only other documentation I have is the sheet signed by the customer, from my office, which has details of my employer, the customer and the standard stuff to which I was referring - the time, date, reason I was on site and a signature from the customer confirming they'd received the new equipment.
