Hi, am buildinga new extension and doing a concrete floor instead of an elevated wood floor that I have in the current house. Will have the concrete floor screeded. Do building regs require a layer of insulation of some sort before or after screeding or is the use of a waterproof membrane enough to satisfy regs? thanks

As mentioned you will need insulation, somthing like 90mm of rigid insulation Kingspan or Celotex or similar below the screed. Exact thickness will depend on the floor area/perimeter http://www.insulation.kingspan.com/uk/pdf/tf70.pdf
To be frank, if you need to ask such a basic question you should really do a bit of research on the regs before you become unstuck.

I've often wondered that too.
I would have thought that people either have a detailed drawing or alternatively have a clue, and have done a bit of planning prior to starting to dig!
But I applaud the enthusiasm to just get stuck in
I recall a guy on uk.d-i-y (google groups) who literally asked hundreds of questions at each stage of the extension build, and built his extension off the back of everyones answers. It got a bit tiresome, but fairplay, he now posts and helps others out following his experience.
At least he remembered the membrane!
You saved me a lot of bother looking through the build. regs online with the link to the Type of kingspan to look for. I needed similar info for my boy`s ( tiny) extension and tho` I`ve been around building work for years, you don`t get all the lowdown if you`re a services fitter (plumber). Genuine Thanks.
