Solid wood floor - underlay?

[AdamD]

Which underlay for solid oak on both concrete and timber floor boards above suspended floor?

You'll need to work out if there's need for moisture control and where you're integrating that. For the timber floors I doubt you'll need any underlay, but some insulation may be of benefit.

 

Can you provide some more details of what's there / what you propose?

Suspended timber floor joists and timber floorboards in one part of the area, and solid concrete base in the other

You are a man of few words, I'll need you to use a lot more of them

 

Damp proof membranes, any? Insulation, any? Thickness of these if present? Etc.
