Can a plumber do the bathroom electrics?

Only if they're also qualified and registered to carry out electrical work, otherwise a qualified electrician needs to be involved.

Do I get a certificate at the end of the job?

You should receive documentation for any certifiable electrical work, and it's worth confirming this is included before the job starts.

Room dimensions, the position of the window and where the waste leaves the building decide most of it. Send those and we can be specific.
