What IEE Regulations apply to underfloor wiring?

wpqs

I am renovating a domestic house. My electrician is suggesting that the electrical wiring should be put in conduit run in screed below the underfloor heating pipes. In order to save costs he wants to run the conduit diagonally across the room. Would this conform to IEE Regs? What other regulations should I consider?

    It's the IET regs these days - more properly know as BS 7671.

    There are a whole host of things to consider - from ambient temperature to the layout of the conduit - e.g. U shapes that pass into cooler areas maybe prone to collecting condensation. No problem running diagonally as far as I recall though. The conduit probably needs to be of sufficient depth to avoid nails & screws (e.g. from floor covering fixings) or be of earthed rigid steel.
