Hi All
The unloading exemption may be the only one useable here, This wasn't a case of me or a family member parked for the sake of it and sat inside, as this happen a lot in many areas, this while it all depends on the council, shows a car with tool and the tiler unloading, so hoping that adds some weight. The inspectors in these boroughs seem to have a 0 minute observation on such contraventions, hence it takes them literally 30 seconds if that to snap, print, slap and go, while it takes the tiler around 2/3 minutes to take his tools upstairs set aside and come back down to do the next unload. A bit similar to when I was loading my car on a Disabled bay, literally went in for 1 minute to get next set of items, come out to a PCN with no CEO in visible sight - This was successfully appealed at NTO stage with the help of this forum

.
Not sure how I can prove the timing of the photos other than the timestamp on iphone, but again as HC Anderson stated in the wider picture it may be of little benefit as it just proves we took a photo at that time, to us during consecutive unload but to the council doesn't literally matter as there is no way to prove the car was there for that period only or for the entire day (as the council would assume).
In respect to the wet ticket that we can discard, its dried and is viewable, so don' think we can use that as any grounds? It didn't rain instantly, while the UK weather does have a tendency to switch within seconds

, the tiler moved his car after unloading the tools, but decided to leave the PCN attached (maybe lazy), so when it rained later it became wet.
At this stage the tiler has nothing to lose, I said I'll assist him in teh appeal, but it is very likely the council will reject this and with the discount at play he may not want to go the full hog
