Does anyone know if the requirement for seperate cables to be run for left and right lights etc, i.e off the same fuse but doubled up off the fuse connection, one to left and one to right, or am I talking nonsense.

Cheers

No legal requirement - but it's generally considered a good idea to have 1 fuse for the left sidelights (front & back together) and one fuse for the right.

This means that if one fuse goes you'll show at least one light front and back!
