That is a different cable head end from any I have seen in use in this
area, so can't give you a definitive answer. However the connection of
the (undersized!) earth connector to the side of the main cutout like
that would suggest TN-C-S.

Agreed.

If you opt for using the screen as a CPC I would be
reluctant to have the gland connection burried in a wall behind a metal
box.

Agreed. An excellent way to introduce corrosion into the CPC. In
addition, although I don't share the panic about using steel as the
CPC I think it must be easily accessible for inspection. Provided
the extra lengths are acceptable I too would look at the loft as the
place to make the joint.
