Is there any reason a circuit fed in t&e, protected by an RCBO, can not be clipped to a accessible surface feeding a socket

Conventional plastic clips probably wouldn't be acceptable these days - the regs require all cable supports to be fire resisting.

Do they ? I thought that the new requirement was to “prevent premature collapse in case of fire” A short vertical run up or down the wall to a socket outlet would seem to be self supporting if the plastic clips melted. A horizontal run along the wall likewise, it would remain close to the wall after failure of the fixings.
If the cable ran overhead which sounds unlikely, then yes sufficient of the fixings need to be fire resistant so as to prevent premature collapse.
I did say ‘probably’ - if there were something else that would support the cable if the clips failed then yes the requirement could be met in that way. The OP didn't mention the run being short though, and the requirement only applying to overhead or escape routes disappeared some time ago. Even relatively short runs would likely need additional support if it turned an internal corner or changed from vertical to horizontal. Collapsing but still remaining close to the wall, may well keep it out of escape routes, but wouldn't meet the current requirements to my mind.
