While lifting some boards to install pipework we found a few cables
that had been nibbled, in one case they had exposed the neutral
conductor and several others where they'd gone through the outer PVC
to expose the red insulation. I've replaced the runs where possible
but had to splice-in a length of new cable (using crimps) when the
cable dropped into a plastered wall. These splices are half a metre
at the longest. In one case the new T&E went to the ceiling rose but
was spliced to a cable without an earth, in others the T&E is
inserted into a length of T. I cut the earth back in the rose but I
haven't encountered T(no E) before so it got me wondering whether
there is any convention when splicing twin+earth into twin (no
earth)? What's the jury's opinion of insulated crimps (with the
correct tool, and either covered with heat shrink or
self-amalgamating tape) for solid lighting wiring?

If a mouse can get at it, it is accessible. So use a junction box.

Why? I've always thought that crimps or/and soldering were the "weapon
of choice"

They might give some advantages if done properly using quality materials,
and skill. But far more chance of cocking it up than a JB. Crimps vary
wildly in quality. I've seen some made out of baking foil. And seen some
results of attempts to solder things.
