That looks like bell wire, but if it really is sheathed singles
(which were sometimes used for wiring lighting circuits), then
that's OK. I suggest running them into the bottom of a junction
box, without trying to seal. You would be able to find a gland
for the single neutral, but it would be harder for the profile
of the sheathed live and earth cable.

1988 Build.

That's quite late for sheathed singles installations.
It was done so the neutral just ran between the fittings and the
live ran between the switches, with a switched live hopping from
each switch to a light fitting.

It stopped being used because separation of the live and neutral
creates lots of 1-turn magnetic coils, which cause interference
with anything which might pick this up - hearing aid induction
loops being such an example, but when light dimmers were used,
AM radio bands become unusable too.


It is not the way the whole house is wired - only the feed out through the
wall to this light.
