I think we've seen this location before, but I may be wrong. However I did a quick search on London Tribunals Statutory Register going back over 12 months, but nothing comes up, so it looks like everybody just coughs-up ! With GSV out of date, we really need to see photos of the approach from a driver point of view. Are you able to take them ?
We really need to also see the PCN, and the video too, please. The video is their sole evidence, BTW. If you can't do the video just give us car reg.number and PCN number and we'll look ourselvs
