We've seen this location before, so you need to study the succesful cases on the London Tribunals statutory register carefully.
There is an advance warning sign on the approach on Winston Way, and GSV shows it has been there since 2018, so this is not a new restriction.
https://maps.app.goo.gl/sBVt5LjPPCX5XbVa6The video show you "charging past" the two blue restriction signs as if they weren't there. Did you know that these signs meant, because they look pretty prominent to me, plus there is text on the carriageway as well, and in very good condition too. I have to say I don't see the basis for a robust appeal at the moment, sorry to have to say it.
