I am going to be fitting a number of sockets and in the past I have simply
used a sleeved length of the CPC from 2.5 T&E for the bond. I find making t
he connections a bit of a faff with the sleeving sliding about so I am cons
idering using some green/yellow conduit wire. With the cost being just a fe
w quid for 10m it seems justifiable for the number of sockets I will be wir
ing and the preservation of my sanity. My question is there a specification
for the bonding wire cross-section? I cannot find anything in the wiki whi
ch generally seems vague on bonding wire cross-section s.
I thought one of the points of *not* insulating the earth is that if you
put a nail or screw through the insulation of the live you are very
likely to short to the uninsulated earth. (It is possible, though not so
likely, to "nick" the live from the "outside"). Certainly it is harder
to sever the live without shorting to earth.
It does rather sound like a legislator getting involved without actually
understanding the engineering. It *might* make the installer's job a
little quicker, but at the expense of greater material cost and
environmental impact, and for no obvious technical benefit I can see.

I don't know if you have to use the same size as the circuit wires when using conduit wire? IIRC the reduced cpc size is permitted for twin and earth flat PVC cable but not necessarily for others.
