Unsurprisingly the PSC information is also (to my understanding) incorrectly filed:
11863251 - has the statement "The company knows or has reasonable cause to believe that there is no registrable person or registrable relevant legal entity in relation to the company"
...but the filing history (incorporation) shows that this private limited company has 100 shares, all held by the person named as director. That's a registrable PSC, no?
Exactly the same story for the second example:
Of course there's nothing to stop bogus companies / persons filing false info in the correct form. There are also plenty of examples of apparently legitimate organisations getting the PSC filings wrong in various ways (see previous threads). It should be possible to (automatically - this appears to be an electronic filing) cross-check some basic information though?
