Data cables in thermal insulation

I am not aware of any such regulation that specifically prohibits this, and in general the absence of prohibition implies permission.

In the vast majority of cases such cables carry minute currents and will not be vulnerable to heat damage if installed within insulation. My only concern would be if numerous data cables bundled together are used for power over ethernet or POE.

In such a situation I would want to estimate the heat production, probably negligible, but needs checking rather than just hoping for the best.

I wouldn't interpret it like that.

The absence of a particular aspect in a standard might still have to pass the test the test of whether an hazard were reasonably foreseeable but usually most of the reasonably foreseeable issues are addressed in a standard.

There have been cases where the HSE issue notices of a particular instance, where new considerations are to be taken into account before standards and guidance is updated.
