150mm hardcore, 25mm sand, 1200g DPM, 50 mm insulation, 20mm insulation to sides to avoid cold bridge, wire fabrication on spacers, install manufactures underfloor heating pipes/kit and pressure test, ST4 concrete. DPM suppose to overlap DPC on walls but can't do unless new build.
Thought the conversion would have to go through building regs and this would be detailed on the plans.
The above has come back from the local council for a current planned extension. Thought it would be the same for a conversion.
The heating pipes will come out of the floor in one area to a manifold.

Most local energy codes are pretty much the same. You have to have perimeter insulation under the slab edge as noted in the previous answer. That's hard to detail without a foundation wall since the standard detail is for the insulation to turn up at the foundation wall to isolate the slab from the cold exterior. You could install insulation and some sort of perimeter finish to the slab edge if there is no foundation wall to die into. Also, if you are installing underslab heating, you need to install the insulation continuous under the slab. Otherwise you are trying to heat the soil below that is always about 50 degrees/

Depending on where you live, a new 4" concrete slab with 6" wire mesh poured onto compacted gravel will be acceptable. You will need to install 2" board insulation below the slab around the perimeter of the foundation for frost protection before pouring. Radiant heat piping is installed and attached to the wire mesh before pouring. Concrete bearing footings will also have to be poured to carry any interior building loads.
You should consult with a construction designer/contractor to provide you the appropriate code and structural requirements, integrity of the existing conditions, design options, feasibility and cost estimates.
Sounds like a fun project!

U have to consult some consultant for that to get exact quotation. U must already be having some idea about it. It should cost u anything between 40-50 pounds per sq. ft.
