Please note the draft Regulations within the guidance have been amended following consultation. The Regulations and this draft Legal series guidance may 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 6 April 2015.

What will change?

  • 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 essentially unchanged from those in guidance related to CDM 2007. HSE’s targeting and enforcement policy, as a proportionate and modern regulator, also remains unchanged.

Draft industry guidance

There are a series of draft industry guides link to external website for the five dutyholders under CDM 2015, and one for workers. 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.

HSE will also be working with stakeholders in the entertainments industry to provide specific guidance for these sectors. An update letter PDF on their progress ia available.

Transitional arrangements

When CDM 2015 comes into force on 6 April 2015, there are  transitional arrangements in place that will run for six months from 6 April 2015 to 6 October 2015.
