Is the heavily taped up cpc of the blue/brown T&E disappearing into the ceiling being used as a perm. live/switched live to the fan?

I’ve not untangled it all yet. I’ve got a number of points from this inspection and the list of remedial work keeps growing.Is the heavily taped up cpc of the blue/brown T&E disappearing into the ceiling being used as a perm. live/switched live to the fan?
....and there is a socket being spurred off the shower so far.
Sounds pretty poor.
However, open question to everyone, just what exactly would be wrong with taking a socket outlet off the shower circuit (or anything else such as ufh, or similar); if electrically it had the usual stuff right such as rcd, Zs within limits etc.
General question on people's thoughts about this.
You can’t run a 2.5mm spur from a 32A 6mm shower.Sounds pretty poor.

Not matter what the Zs is. The cable is only rated at max 27A.
So unless you ran it in 6mm, which would be some effort for a 2g socket then it’s not going to be compliant.

That is exactly what my head said at first too.
But....
Overload protection - each appliance protected by 13A fuse in plug. OK, two at once would be a bit interesting but unlikely.
(In some circumstances overload protection is allowed downstream - I'd need to read that bit again to comment further.)
Fault protection - it's RCD protected.
It's a truly horrible design but is it actually non-compliant?
That makes the upstream 32A MCB more likely to trip, and the spur is only drawing the heater current?What about shower running at same time as someone has plugged a heater in?
The breaker and 1st leg of 6mm to shower are correctly matched, so any overload here is dealt with normally by 32A breaker tripping.What about shower running at same time as someone has plugged a heater in?

If it was ran in 6mm then technically it could be safe.
But as far as I’m aware a shower has to be a dedicated circuit and nothing else on it.
I don’t know if it does. When I rang NAPIT the chap I spoke to said it should be a dedicated circuit.Which reg covers that?
As a B32 wouldn't trip at all with a load of ~46 amps, the question is how hot does the 6mm get for the duration of the shower.Im just thinking, if the shower and heater together were above the MCB rating, but not enough to trip it. Just thinking out loud.
I agree that angle needs exploring, what requires a dedicated circuit. Appendix 15 comes to mind, but I don't have book here.But as far as I’m aware a shower has to be a dedicated circuit and nothing else on it.
Last week NAPIT told me "not to worry" about an RCD taking 0.5 seconds to trip due to a PV system back-feeding and not shutting down very quickly.When I rang NAPIT
As a B32 wouldn't trip at all with a load of ~46 amps, the question is how hot does the 6mm get for the duration of the shower.
It would trip after roughly 15 minutes with a 50A load.
We need someone to plug an EV into the other side of the socket!

If it is electrically sound then to me the problem it sort of violates the "principle of least surprise" in that you might have a lone socket that is still powered when someone thinks they have isolated the RFC/radials related to that.However, open question to everyone, just what exactly would be wrong with taking a socket outlet off the shower circuit (or anything else such as ufh, or similar); if electrically it had the usual stuff right such as rcd, Zs within limits etc.

I’m not sure you can make a sweeping statement like that.If NAPIT or any scheme for that matter say it is okay then there is your answer, it probably isn't okay.
