with electrics, if you're replacing like for like, you're entitled within the new laws to do this without having to get a qualified spark in. so if you are taking one shower unit out and putting a brand new one in exactly the same place without changing any of the wiring etc, you don't need a spark.
however, if you're ever unsure how to do anything with electrics, it always pays to get a professional in first to do the job. saves time, aggro and money later :yesnod:
Thanks for clarifying that point GRR
