I think I have gleaned sufficiently from other posts that it is acceptable to use good quality inline crimps to extend cables for terminatingwithin a newly installed CU. Invariably,for 2.5mm T&E and 1.5mm T&E these crimps will be red in colour. I ask the experienced electricians on this forum: is it best to cover the crimp with suitably coloured insulating tape or left as it is?

Blue for 2.5mm and Red for the 1.5mm.

Insulation tape is best left in the wholesalers - pointless. You can heat shrink if you like but no need

No, ...Never use PVC tape on crimp connections always use heat shrink!!! For an even neater job you could use bare crimps with 2 layers of heat shrink to insulate them. Or you can buy heat shrinkable insulated crimps. For aesthetics sake, i always like to see the appropriate core coloured heat shrink over crimp connections...
 
If you use the uninsulated ferrules crimped with a decent indent crimper and put 2 layers of heatshrink over it makes for a more streamlined joint.

Unfortunately there's no way to 'like' someones signature on this board but I did try Biff :)

I'm probably just oldschool but I much prefer crimped ferrules. Great mechanical strength (assuming you use a good crimper) and a very low profile and neat form factor when used with heatshrink; the joints are almost invisible when they're in a wiring run. I've used Wagos (once or twice) but you hardly ever see them in this country. They're convenient but they're helluva bulky especially if there's a few of them in the same area, I can't really comment on their reliability because I haven't sufficient experience with them.

That's what I think too. I would either crimp & heat shrink like you say, or solder and heat shrink, but that's cos a) I'm an old gadgee and old fashioned and b) I know how to solder properly !!
