As you say it is normal for the lighting and fan to be linked with the double isolator (which must go outside the wet room – normally high above doorway). You can obey / get around the 50mm rule by taking your lighting and extractor fan wiring vertically up to the top of the joist (rather than run over the surface of your plasterboard ceiling) and run under P clips. Then as you say you easily lose that horrible plastic trunking at least for the ceiling (which would only collect condensation and mould anyway). Its all an easy and low cost fix except for the wall tiles.
I would not assume that because they work for the council that they will work to spec. many of the trades will do whatever they think they can get away with without a foreman or customer looking over their shoulder.
What is a bit legally mad is that now its installed if you or anyone electrically technically competent want to reroute it (even if you don’t have Part P) I believe you are now legally allowed to do so as you are not extending or adding to a circuit! (but check this). Obviously if you decide to DIY then remove your trip or at minimum tape it up when you work.
Very best of luck with your call to the council . (sorry Im so far away or i would have come and at min made it safe for your parents - its only a 30minute job to fix the overhead wires - slice then add a loop up to over the joist to lose that horizontal trunking - Im a bit worried that those overhead plastic channels have created the equivelent of a drip loop into your fan if its underslung, please get it sorted asap or if your folks need to use it until you get it sorted snap the channel covers off and squirt blobs of silicon at the end of the channels )
