In the DIY FAQ it says:-
There are new requirements for all wiring support to not fail as a
result of fire (i.e. this no longer just in escape routes). So cables
supported in plastic trunking or in plastic conduit will also need
additional metal clips.
Does this mean that metal clips are required in *all* plastic trunking
or only where the wire can fall out? I.e. does trunking running along
the floor or on a rafter/ceiling require metal clips?
Anywhere that failure of the support from the trunking could cause an
entanglement hazard...
So that would be vertical horizontal runs on walls or overhead
certainly. IMO whether that also applies on floors will depend on
circumstances.
It does make using trunking a bit of a pain and self-adhesive trunking
becomes pretty useless as you still have to knock nails or screw
screws through it.
Apart from the D-Line clips no one seems to be producing hardware to
provide this cable support, are there any well thought out systems
available that provide the required support, are easy to install and
look reasonable?
Lots of places seem to have:

They're OK but have the same problem as anything else mounted inside
the conduit, you have to drill and fix the clip before putting the
cables in. The above do have the significant advantage of making it
fairly easy (by the look of it) to get cables in and out after fixing
the clip.
Also, can you get them for all sizes of mini-trunking, in particular
the small sizes.

Yes, they're the ones I referred to, lots of people sell them but it's
not very clear how they work.

The D line trunking clips are fine but you need to use the correct trunking, for instance Tower trunking is incompatible as it has a ridge down the centre to enable a divider to be clipped on just where the screw needs to go. I made the mistake of using it and ended splitting the D line clips and used two screws instead of one it was a real PITA.
