Does anyone know of a readily available connector to directly connect
some 10mm T&E to 2.5mm T&E, that will go in a reasonably small box? I
suppose I could use just some of the strands, but that would be rather
poor practice. The best I have thought of (and have) is a surplus DIN
main switch, left on of course. Any superior ideas?

60A chocblock might do it - strip both cables the full width of the
block, back the screws right off and stick the 2.5mm through and out
the other side. Take a bradawl or similar and make a hole in the end
of the 10mm so you can push the 2.5mm into it, then squeeze it back
carefully with pliers so the 10mm will fit into the block.

I like that idea. 60A chocblocks will take 10mm but I do like the idea of
embedding the 2.5mm in the 10mm and having 2 screws over it all.

Having discovered after buying one that 60A junction boxes are rated for
only 4-25mm wire (and 2.5mm could presumably slip out beside the screws
even if folded over) I think I am going for that solution. The
connections will go in a metal box, along with a block connector to
terminate the redundant meter tails, so I think chocblock is acceptably
safe.

I've got to connect 10mm to 4mm (10mm is from SWA), I reckon 60A choc bloc with 10mm on one side and folded over 4mm on the other will be just fine.
But 2.5mm in those size terminals, as you say could slip out of the screw.
