Key changes of the new CDM Regulations 2015

The Construction Design and Management (CDM) Regulations came into force on 6th April 2015. Written to replace the out-dated CDM 2007, the new regulations provide guidance on the legal requirements involved in construction work. Virtually everyone involved in construction has legal duties to fulfil and when a project becomes notifiable, a CDM co-ordinator is required.


A few changes were recently made to CDM 2015

As outlined by the Construction Industry Training Board (CITB) the key changes to the Construction Design Management Regulations are as follows;

  1. All projects must have:
  1. Project where more than one contractoris involved (domestic or non-domestic) must have 1 above plus:
  • principal designer and principal contractor must be appointed
  • a health and safety file
  1. If work is scheduled to:
  • last longer than 30 working days and 
  • have more than 20 workers working simultaneously at any point in the project
  • OR exceeds 500 person days

All of 1 and 2 above plus

  • Client must notify project to HSE

CITB have also produced a useful infographic which can be printed out and used as easy reference:
