    However, the question remains that people have claimed The Building Regulations state requirements for fans and their operation.

    They do not


    I totally agree with your last point.  no they do not.  

    But if you choose to install one  134.1.1. states you will take into account manufacturers instructions. and I have not found one yet that does not need a 3 amp in line fuse so ,MCB won't cover it, and either a double pole or triple pole isolation.  so if fan goes in then you need isolation, But you don't have to put fan in.
