I'll never understand how someone could deem this safe???
I mean judging by the over-soldering of the pipes under the bath the plumber must have thought of future leak-proofing or am I being equally as daft? Joking....
In my opinion the plumber could be brought to rights if they can locate him, regardless of who's regulation it comes under he has created a death trap and as mentioned before once the seal goes on the bath or the tap fittings leak then it will run directly into the cutout. Building regs, DNO's regs and basic H&S have all been breached here and regardless of where exactly there is a reg against it it still comes down to a serious danger and should be brought up with the owner and reported to the DNO... its your duty as an Electrician to ensure this danger is at least looked into by the DNO with thought on re-siting the cutout to an outside wall and/or a plumber to see if alterations can be made to resolve the obvious danger.
Ignoring this could be costly and although its DNOs property and the plumber fault the fact you are doing electricals on the installation means its your responsibilty to take steps to see a solution for the hazard.
