TNC-Separeted after the meter

[kropaske]

So I went to see a job yesterday, its a house converted to 3 flat. Fairly good install, dual rcd board feed directly from tncs cut out. I ask where the meter is and she pointed me to the cabinet in common area downstairs where main incomer is located along with 3 meters for each flat. As you can see in pics there is no earth provided there and they separated pen at consumer side of the installation. My understanding is that it should be separated before the meter. I am going to call dno to check what records of this install they have.
Property is in London so earth should be provided by dno.
Black meter belongs to the client
Any thoughts on this one?

What is at the other end of the cables.

Another cut out tncs type with tails and earth coming out to CU. Did not took pic of that sadly

From the shrouds on the cables it is almost definitely DNO work, typical London.

It does look genuine dno, perhaps not the tidiest.

Can’t quite get my head around this.
3 meter supplies to flats each having a DB.

What about the wallpaper...

Yes that is a issue

What about the wallpaper...

Was wondering when someone will mention that, given that most members of this forum have great attention to details and very sophisticated taste - ;
