However the NICEIC link from the reference section:

Why do these two electricians say shouldn't and must not, where as the NICEIC say is not required?
Is this just a case of Chinese Whispers where "is not required" becomes "don't" which becomes "mustn't"?
Also what are the extra problems associated with having this seperate earth?

NICEIC said:The NICEIC is regularly asked whether BS 7671 requires a separately-run, independent, protective conductor to link the supplementary equipotential bonding in a bathroom or shower room with the Main Earthing Terminal (MET) of the installation. The answer is that no such independent protective conductor connection is required by BS 7671.
