Wow,

Thank you both for your answers, the roof space in question is only ever
going to carry lighting and the max loading at present is 800w therefore
3and a bit Amps max under normal conditions, so will apply regs/OSG as
suggested, but expect you are both right and I can put cables under
insulation. Will probably tack to side of joists as well.

Happiness is a bank holiday spent wiring!!!!!

In my loft there wasn't too much cable leeway so I insulated between
the joists, then insulated over the top with a second layer leaving a
small channel for the cable runs to go along. Where there were
bathroom halogen lights, I left this bit uncovered. It's now pretty
obvious where the cable runs are if I need to trace one.
