The thing is, even you have a fully-trained, competent and experienced inspector, who can use their skill to, for example, determine that a shower is not RCD protected but is otherwise soundly installed, you still have a problem. Obviously this doesn't comply with the current regs, but how should it be coded? It has basic and fault protection. This is very subjective, and there is currently no right answer. So different inspectors could reasonably come to different codings for the same installation. So you either need informal guidelines like NAPIT codebreakers, or statutory minimums.
And, how many of us take a shower cover off to check earthing and tightness of the terminals. Many electric shower units have no exposed conductive parts, and the water outlet fitting is made of nylon so a loop test can not be undertaken easily.
