Just came to fit some socket outlets from Toolstation and realised the
faceplate screws aren't connected to earth.

They're the top ones in this pic:

Older MK version with earth connection is below.


I thought all sockets followed the MK pattern with the result that
using either the earth connection on the faceplate or the earth
connection in the back box would result in everything being connected
to earth. But if someone made the earth connection to the back box on
the Toolstation version, any connected appliance (double insulation
and plastic earth prongs aside) wouldn't be earthed. Is that right?
Is this something new? Or something cheap?
