realistically, you know the cables are there. you're not a plumber, so in the real world, it's not too big a deal.

With your Electrical Installation Certificate there should be a page titled Schedule of Inspections, essentially a tick sheet.
On here you should find a comment Segregation/separation of Band I (ELV) and Band II (LV) circuits, and electrical and non-electrical services, if this has been ticked then this claim is incorrect.
Another comment will state Cables concealed under floors, above ceilings or in walls/partitions, adequately protected against damage, again if this has been ticked then this claim is incorrect.
