This is dependent on the consumer unit and protection you have in place. if there's isn't rcd protection already in place you will need this for additional sockets and ideally for existing socket outlets, if there is space to install a new circuit onto your existing consumer unit with rcd protection then no you wouldn't need a metal unit, unless it did get upgraded then it would, hope this helps
This depends on if any circuits within the bathroom are being worked on if so to produce a minor works or installation certificate they must be rcd protected as they have been worked on. it wouldn't matter about the original house sockets if they are not touched they are not part of the electricians installation working on the bathroom, if it was me i would drop a note on the certificate to recommend a full eicr and that house sockets are not rcd protected but not worked on hope this helps
