UK Dilemma

[Anyidea]

A recent dilema.
When inspecting some wiring in an office block,we have discovered that the previous sparkies have fed the lighting via a multicore swa cable.This has about six feeds and neutrals down it,and the common earth sheath. It is fed via six seperate mcbs at the dis board.
I know it seems bizarre but is this ok.
After all its judt the same as a common trunking etc.
As long as the cable is fit for the highest voltage present.
Opinions please.

As long as the Earth loop is good for the highest rating breaker, I can’t see a problem.

I would be wary of the N cores for each circuit being mixed up, hopefully they are all in the corresponding correct terminal of the N bar. Since they all emerge from the one cable, it would not be simple for someone to check visually.
