Our CDM online course provides essential training on the Construction (Design and Management) Regulations 2015 (CDM 2015). The course explains where the CDM Regulations apply, the responsibilities of different duty holders and how health, safety and welfare should be managed throughout a construction project.
Designed for clients, designers, principal designers, contractors and principal contractors, the CDM training explains the key duties placed on organisations and individuals involved in construction work and how they can meet their responsibilities under CDM 2015.
Our online CDM course is CPD accredited and RoSPA assured and takes approximately 2 hours to complete.
Why is CDM training important?
Construction work can expose workers and others to significant health and safety risks. CDM training helps duty holders understand their responsibilities and how to plan, manage and coordinate construction work safely.
The Construction (Design and Management) Regulations 2015 (CDM 2015) set out health, safety and welfare requirements for construction projects in Great Britain. Understanding the CDM Regulations helps duty holders know what is expected of them throughout a project.

The CDM training helps duty holders understand their roles and responsibilities for managing health, safety and welfare throughout a construction project.
