Are you planning on stick building the frame? 

 

Have you considered blown insulation AKA cellulose. 

 

There's lots going for it.

No it will be open panels. Preferred the rockwool approach as we can do that ourselves

Getting the cellulose pumped isn’t cheap either. It’s good, but rockwool + DIY will be more cost effective.

And 450mm isn't enough to justify beam and block.

The very clear difference is that below a slab you can have ground, (which insulates) or insulation, whereas below beams you have a draught.
