True. I always forget that one, since it's not a situation I come across! There are, in fact, only three types of notifiable woek mentioned. The third is 'work in special locations' - but, as you say, that is subdivided into 'bathroom zones' and the case you mention.It would seem work in a room containing a swimming pool or sauna heater is also notifiable.Now, the only things which are notifiable (in any room) are 'replacing a CU', 'installing a new circuit' or work within the prescribed 'zones' of a bathroom.
