What are the CDM Regulations?

The Construction (Design and Management) Regulations (CDM) are the main set of regulations for managing the health, safety and welfare of construction projects in the United Kingdom. In April 2015 the Construction (Design and Management) Regulations 2015 replaced the 2007 regulations, bringing about a substantial change in the defined duty holders and their responsibilities to ensure the health, safety and welfare of their construction projects.

CDM applies to all building and construction work and includes new build, demolition, refurbishment, extensions, conversions, repair and maintenance

The replacement of the CDM regulations in 2015 saw the removal of the CDM Coordinators role, and the introduction of the Principal Designer. Creating three main roles for managing health and safety of a construction projects, with the client having overall responsibility for the successful execution of the projects, and the Principal Designer (PD) and Principal Contractor (PC) leading during the different phases of the project.

​All projects must have workers with the right skills, knowledge, training and experience (competency). Contractors providing the appropriate supervision, instruction and information, and a written construction phase plan

Projects with more than one contractor involved must have a principal designer and a principal contractor appointed and a health and safety file If the planned work is scheduled to be longer than 30 working days, have more than 20 workers, working simultaneously at any point, or exceed 500 person days. Then the client is responsible to notify the Health and Safety Executive using the F10 notification.
