snipped
service headend, which is under the black main fuse block, and properly
clamped to the outer braiding of the supply cable.

This bit was really the reason for my post, cos I'm not clear about the
main
'supply' earth. The other issues I'm Ok with. So I take it that it's
possible to confirm that mine is definitely a TN-S system (he says, having
just looked at the FAQ again!)? If I scrape away the black crap which
seems
to cover the electrical service headend, I should find braid there, then?
(As you'll appreciate, this is well-nigh impossible to get at to even
check,
right now).


The service mains cable you have, by what is showing in the pictures, is an
older wire armoured type, so it will have a braiding around it. Wither it
is properly earth bonded further down the line is another matter, but best
to bond it anyway to make sure. Both water and gas services need to be
bonded on the consumer side of the installation. This means on the parts of
the pipework that go into the house and not on the parts that comes from the
outside of the building.

Good luck with it.
