What depth insulation do I put down for Underfloor Heating?

There is a minimum thickness of insulation required by the building regulations, this is to achieve the required U-values. Either check with document L of the building regulations as thickness of insulation is now dependant on room size to external wall ratio, and can differ for different properties. Or consult the architect.
