JohnD said:grouping for two multicore cables, enclosed method 3 or 4, is 0.8
so capacity is 20A x 0.8 =16A
I can't find conduit capacities for T&E
But on a 32A type B MCB it gives no leeway for an unbalanced ring.
Just use 2 conduits,one in and one out

I would clip it.Just bear in mind it should not be covered by the loft insulation and that some time in the future you may add more insulation
...but doesn't provide the freedom...
