And, a piece of 2.5 T&E has two different thickness wires - the L&N and
earth. Do you use the same size crimp on all three? Or drop a size for
the earth? And if you drop a size, what do you do when crimping 1.5mm
(and there isn't a next size down readily available)?

It's a shame these haven't been answered. My experience of screw
terminal isn't that good in that copper appears to creep and things can
get hot as a result of the loosening.

Then you're not tightening them correctly - it's as simple as that.

Use a screwdriver with the same blade width as the screw, and tighten
firmly. If a single cable into a terminal designed for three, double it
over. If you're worried about stripping threads, practice first. And use a
screwdriver in good condition to avoid damaging the slot.
