Protected corridor lighting cabling compliance

One of my daughters bought a flat in a converted warehouse, I was never happy about the standard of construction as it has internal access balconies built out of timber decking boards, however my daughters flat directly accessed one of the original internal fire escape stairways across a concrete landing and the stairwell is a sterile area with the electrical installation installed in steel conduit, along suitable fittings.

On the fifth June last year the Fire Brigade put a closure order on the building, luckily my daughter had sold her flat as there is still 24/7 security patrols stopping people from entering their own homes.

Since the Grenfell disaster there’s far less tolerance of what may be considered minor issues and my insurance like many others have capped the cover provided for fire related claims, indeed some insurance companies have stopped providing electricians with professional indemnity insurance because of it..

The “it’s only 600 mm of cable, so it can be ignored” approach would not be enough for me, I would want reassurance that the whole fitting is suitable, including the cable.

I agree, everyone is far more cautious and rightly so. I also agree that as the designer responsible I'd like reassurance that the whole fitting is compliant, which I'm struggling to do as the fittings don't appear to be covered specifically anywhere that I can see. But if it's all one void, the luminaire is a plastic fitting does the type of cable make that much difference and as they allow socket outlets in the space which could have anything plugged in I'm struggling to "interpret" the requirements. The suppliers I've spoken to have recommended using a fire resistance hood and ensuring the cable is contained within it.
