Ring mains are parallel, not series. Which means that more than one thing going out is a clue to where the fault is, and an indicator that the job is definitely per the regs one for a qualified electrician. Conversely, only one device going out points the other way. Although IP-rated fittings inside one of the zones is still a qualified electrician job. But bringing a mains powered non-IP-rated portable substitute into the room in the interim is a truly terrible idea. The regs also specify that there's a minimum distance that stuff should have from baths, sinks, showers, cisterns, and whatnot; and that they should not be reachable at all by a wet human being.
