Thanks for your reply.
So I've now read that the signs on red routes don't actually run parallel to the road (where you intuitively look for them) but actually face the traffic (perpendicular to road), so once you've pulled up the signs aren't very obvious. So annoying, try your best to find a loading bay and still get done.
In the pictures provided the sign was maybe there, you can maybe see the back of it. Do their images not need to show the front of the sign though? I recently had this with Hackney council, they made a lot of effort in proving I drove through school street signs, not realising I had a permit to go through them. One fight after another driving in London!
Thanks again.
