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?

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?

I recently installed a length of SWA outdoors. I cut short sections of steel band and moulded them inside the cleat - and then put the fixing screw through the whole lot. Not all of them, just at sufficient intervals to prevent it causing problems in a fire. Got the idea of doing that from another forum. My point being that I couldn't find any other good way of doing it. Haven't got round to all the indoor cabling that needs doing, but all I've seen so far is some rather pricey cable clips - https://www.tlc-direct.co.uk/Products/TCFC1.html - I presume that if a cable runs through the middle of a joist it doesn't need protecting (what would you clip it to if the joist is burned through!). Similarly running a cable in a vertical chase seems pretty low risk. If people think differently, then I'm surprised there isn't more choice of protection available.
