There are regulations as to mixing extra low and low voltage cables in same tray work and in drilling holes in beams to feed cables through but very little as to extra low voltage.
The regulations don't exclude extra low voltage from requirements like RCD protection but I consider this is an error in the regulations as any separated extra low voltage can't be protected by either earthing or RCD.
Regulations as to using fire stop in holes and heights of sockets or displays (Part M) will apply but one is still allowed lift-able floor plates so not easy to work out exactly and Part M can be down loaded like Part P so easy to look up.
