The requirements have been removed from Part B, but they have now been included in BS9991

regards burn

That will be
BS 9991:2024 Fire safety in the design, management and use of residential buildings.

In a commercial building, the companion standard  is probably

BS 9999:2017: Code of practice for fire safety in the design, management and use of buildings.

I don't have a current copy to hand here, but I'd be most surprised if it was not very similar.

Data cables incuding fibre oprtic cables, are covered by BS 7671 see 110.1.2 (vi). It does not surprise me that data installers are unaware of the need to comply with BS 7671 from the installations I commonly see escecialy in respect of the need to support cables just like any other cable. As for this particular case the cables should be prevented from premature collapse with metalic cable ties not nylon ties.
