Have you got cables running through it?

I doubt it’s an extraneous conductive part in its own right and likely to be not accessible to touch

Behind plasterboard? Hardly likely to be accessible, so not an extraneous conductive part that is likely to come into contact with a person. As above, just ensure the circuits have RCD protection

Yes there are cables running behind the plasterboard in plastic conduit . The circuit will be on a rcbo.

Imagine water gets spilled and gets behind the skirting touches the stud work which is live due to a screw that penetrated the cables.

that's why you have the RCBO.

Sounds to me like someone is trying to get an unecessary extra.

was a case of a woman electrocuted exactly same scenario. no testing would have picked up the fault. although the report does not say, it's most likely that a RCD was not fitted to the circuit. if the metal stud had been earthed ( which is not a requirement ) it's probable that testing would have picked up a L-E short.

Worth remembering that cables concealed in walls with metallic parts and metallic frames are subject to having additional protection to them by an rcd in accordance with 415.1.1 or be mechanically protected or be installed in accordance with 522.6.204.

Earthing or bonding metallic parts in walls should not be necessary unless the metallic walls meet the definition of an extraneous conductive part

i'd never consider buying a house with studded walls, metal or wood. for me, walls should be constructed of bricks and plastered. plasterboard is for ceilings.

Welcome to the world of new builds, be it homes or commercial buildings, it’s just the way of the building trade.
If it’s not load bearing, stud it.

Wiring within metallic walls is a ball ache tho and you end up scratched to hell

Apart from the fact, that the testing was conducted by a Painter and Decorator, at the time of construction, there was no requirement for RCD protection.

No. Think thats the career going up to check up on him.
 
Plasterboard walls are one thing but when you see polystyrene blocks used for 'block and beam' construction you begin to wonder!!
