Any question answered...

That's a private car park. I can't find any contact details for it on-line, but this suggests that there probably aren't any cycle parking spaces. I may be out of date here, but I think cycle parking has only been installed in some (underused) public car parks in the City.

I think you mean that all the city if London car parks have cycle parking. In all the examples I've seen there is bike parking opposite the security guard room so there is someone overlooking the bike almost all the time.
