Would this be a classic slab over insulation affair or are there gains to be had in insulation terms by using block and beam or suspended wood? I ask because the house is in quite an exposed location and I'm keen to make it a warm house from the outset else the heating bills will be crippling. .
what slab arrangement for a 3 storey timber frame house?

Personally I prefer concrete over timber, however you would only use B&B if you have a large void to cover ie; your damp course being high! Insulated concrete/screed slab with UFH would work well - 2 great conductors of heat.
Essentially the B&B is a suspended concrete slab.

OK, so here's the floor/building construction I have at the moment:
Industrial building, engineering brick walls with no DPC, 2 layers of brick with no appreciable cavity that I can see though there may be odd voids( Some ventilation ducts are built in). Some wall skins are coursed or rubble stone. Finished in a roughcast cement render
The floor is predominantly an existing concrete slab, and I'm presuming cast directly onto a hardcore base with no insulation
Would it thus be easiest to slab on top of this, subject to it being firm enough? (it used to have many water filtration tanks sat on it at an estimated 15 tons each so hopefully so) and if so, would it be OK to DPC, insulate and slab it, or would I need to break the concrete out, hardcode, sandblind.. ?
There is no apparent DPC in the existing walls - can the BC make me install one? I don't find any evidence of damp either - seems these walls breathe weoll enough as they are..

I'm pretty sure they can't make you fit a proper one, or even inject one. I don't believe (though I stand to be corrected) it will even be the slightest issue with them.
Floor - no idea. It might well be strong enough, but...?
