Thanks for the clarifying questions, and the suggestion of the email subscription alert off the Council website - i've done that now, so that's something useful learnt too.
I did not see the Suspension signs (and don't know when they went up; and I did not ignore it).
It's a residential street so apart from a couple of EV-bays whcih are marked out to a one-car size it is one long dotted area for Resident Parking (i.e. it's not like there is a series of marked out parking bays).
The nearest Suspended Notice was on a 'Resident Parking Only" council sign which is not in front of our house. The EV bay had no sign on it.
My main question is whether is established precedent around what has historically been deemed 'reasonable' for signage.
I find it a little contradictory that different departments of Camden would choose to put Official Notices (including Planning Permission notices) on the post right in front of our house, and NOT do so for Parking Suspensions for Tree-cutting when the EV-bay in front of our house would also have been suspended presumably. I see afterwards that lamposts in front of other houses pretty much all had Suspended Notices on - but ours didn't.
Thank you all for the responses. The photo below with the gate shows the post right in front of our house which include the E.V. bay as well as non-E.V..
