A recent article regarding the proposed revisions to the CDM Regulations 2015 (Construction Design and Management), published by HSE (Health and Safety Executive) stated that, subject to Parliamentary approval, new changes will come into force on 6th April 2015.

The new regulations effect both construction companies and domestic clients.


The draft Legal (L) Series guidance is on the legal requirements for CDM 2015.  It’s being made available in advance of the Regulations coming into force on 6th April to help people who have duties under the Regulations to make preparations in advance.

It’s worth noting that the draft Regulations featured within the guidance have been amended following extensive consultation. The Regulations and the draft Legal Series guidance could be subject to change while the Regulations are awaiting Parliamentary approval. The final version of the Legal Series guidance to support CDM 2015 will be available on the 6th April 2015.


  • Principal designer. The replacement of the CDM co-ordinator role (under CDM 2007) by principal designer. This means that the responsibility for coordination of the pre-construction phase (which is crucial to the management of any successful construction project) will rest with an existing member of the design team.
  • Client. The new Regulations recognise the influence and importance of the client as the head of the supply chain and they are best placed to set standards throughout a project.
  • CompetenceThis will be split into its component parts of: skills; knowledge; training and experience; and, if it relates to an organisation, organisational capability. This will provide clarity and help the industry to both assess and demonstrate that construction project teams have the right attributes to deliver a healthy and safe project.

The technical standards set out in Part 4 of the new Regulations will remain largely unchanged from those in the guidance related to CDM 2007. HSE’s targeting and enforcement policy, as a proportionate and modern regulator will also remain unchanged.


There are a series of draft industry guides for the five stake holders under CDM 2015, and one for workers that can be downloaded from the CITB (Construction Industry Training Board) website. These are available before the Regulations come into force and may be subject to change. They set out, in practical terms, what actions are required to deliver a safe and healthy construction project.
