The video is shot head on so we can't see the signage from the driver's point of view.

Here's how it looks on street view - which definitely looks clear. Not sure how old the Google images are, but are the two keep left signs no longer present?

There's a single round blue keep left sign, and the bollard. The GSV is from 2025, so is accurate.

I may just appeal stating the driver rarely drives in London and made a genuine mistake (which is all 100% true), expecting a rejection but you never know.
