But I can't find a supplier of small amounts (say 5m) of suitably

I think you'll find it almost impossible to get 35mm flexible conduit up a
foot *through an average width cavity unless you remove several bricks on
each side. Unless the cables are well overrated the grouping factor will be
likely to derate the cables to below protection level.

In that case I suspect I'll just let the insulation installation crew
do what they think is right. They seem to believe that there is no
problem, and that my proposals are OTT.

I'll endeavour to address any issues during the rewire.
