Cables routes over doorways

[chocolate]

I have a door way and on either side, a wall light is to be installed. Above the door way of a flat roof into which there is no access.

The clients are removing the existing door and replacing it , whilst at the same time, they are having the walls dot-and-dabbed with plasterboard to cover up some brickwork.

The floor is also solid concrete.

So the option of going down and under, or up and over are not available. So the cable has to run up the wall from the left hand light, across the wall and then down to the second wall light.

The cable ( T&E ) will be behind the plasterboard but do I have no other option but to install it in metal conduit to provide the necessary earthed mechanical protection as the cable will be in the part of the wall that is not within expected zones ( especially above the door ) ?

It will have RCD protection because it is less than 50mm below surface.

And advice ?

run it up the wall from one light across the wall within 150mm from ceiling and down to the right hand light, surface on the brick in capping and the boarded over no chasing sounds brill
