Statutory basis, cited on the form

Guidance and standards relied on

These are not law. HSE guidance carries no statutory force in itself, British Standards and NASC technical guidance are industry documents, and the Joint Code of Practice is an insurers' code. They are what the document is built to — and where a court would look for the standard of the reasonable contractor.

  • BS 8204-1:2003+A1:2009 (concrete bases and cementitious levelling screeds) and BS 8204-7:2003 (pumpable self-smoothing screeds)
  • BS 8203:2017 (resilient floor coverings — the 75 % RH substrate moisture test)
  • BS EN 1264-4:2021 (embedded water-based underfloor heating — installation)

What it is not

It is not a completed document and it is not health and safety advice. You must adapt it to your site and have a competent person complete and sign it off. See why we don't say "compliant".
