Up to you. The plaster won't hurt it, and it's not mains nor gas nor

Though to be honest for LV stuff like this I'd be looking at a larger duct,
say 3" square in a hidden corner somewhere even if it extends cable runs
considerably.

Indeed. After an exploratory vertical chase, I pulled off the skirting
and chased horizontally to the corner.

Then I went out and bought a reel of Cat-5e.

I'll put a vertical conduit in the corner where no-one will notice.

Thanks for the lateral thinking !

Cheers,

Paul.
