CDM 2015

The CDM Regulations 2015; and what they mean for your business.

The new Construction (Design & Management) Regulations 2015 came into force on 6th April 2015 and replaced the CDM Regulations 2007; these being the main set of regulations for managing the health, safety and welfare on construction projects.

The CDM Regulations applies to all building and construction work and includes new build, demolition, refurbishment, extensions, conversions, repair and maintenance. The CDM Regulations place responsibility for managing health and safety of a construction project on three main duty holders, these being the Client, Principal Designer (responsible for co-ordinating the pre construction phase) and the Principal Contractor (responsible for co-ordinating the construction phase).

The overall aim of the regulations is to make health and safety an essential and integral part of the planning and management of projects, so as to reduce the health and safety risks of those who work on the structure, those who will use it as a work place, or others who work on the structure once it’s complete.


A Client under the CDM Regulations 2015 is defined as anyone for whom a construction project is carried out. The definition includes both commercial and domestic Clients; however, the Regulations apply in full for Commercial Clients.

Commercial Clients are those whose project is associated with a business or other undertaking; whether for profit or not. If you are having construction work done, the CDM Regulations 2015 place a number of specific duties on you, as a Construction Client. The extent of these duties will be dependent upon the type, nature and complexity of the project. For many projects you will need a CDM Advisor/Consultant such as Marpal, to help you comply with these duties.

Principal Designers

One of the significant changes to the CDM Regulations is the replacement of the CDM Co-ordinator and the introduction of a new role of “Principal Designer”. The Principal Designer is not the new CDM Co-ordinator. The Principal Designer has a significant role to manage, plan, coordinate and monitor health and safety information during the pre-construction phase. Under the CDM Regulations 2015, it is expected that the Architect/Lead Designer will become the Principal Designer.
