Health and Safety The Construction (Design and Management) Regulations 2015

The Health & Safety Executive (HSE) consultation on the replacement of the CDM Regulations 2007 commenced on 31 March 2014 and ended on 6 June 2014. The new regulations came into force on Monday 6th April 2015. The draft Legal (L) Series guidance was published on 9th January in order to help anyone who has duties under the Regulations to prepare in advance.


  1. Removal of the CDMC role and the introduction of a new role of the Principal Designer
    The 2015 CDM Regulations will see the introduction of a new role that of Principal Designer, who will undertake the majority of duties of the CDM Coordinator (Who will no longer exist after October 2015), with the one exception that the Client will be responsible for the collation of relevant pre-construction information and making sure it is communicated to all roles. The role of principal designer could be an organisation providing the Principal Designer role, the architect, clients’ agent, or a project manager.
  2. Domestic clients (homeowners) no longer exempt
    The 2015 CDM Regulations will apply to domestic client projects (homeowners having construction work carried out on their homes), however, domestic Clients have the option to transfer their duties to the contractor or principal contractor (If more than one contractor working on the project). Alternatively, the homeowner may choose to have a written agreement with a principal designer to carry out the duties.
  3. Removal of the Approved Code of Practice (ACOP)
    The HSE have published their guidance which is intended to replace the requirement for an Approved Code of Practice.  In addition CONIAC (Construction Industry Advisory Committee) have issued a set of Industry Guidance for each of the Roles under the 2015 Regulations. (Copies on our web site)
  4. Threshold for Notification Amended
    The current requirement is for notification to the HSE whenever a project is expected to last (a) more than 30 days, or (b) will involve more than 500 person-days of labour. The 2015 Regulations have been amended to align with EU Directive requirements and amend the wording to: “more than 30 working days and more than 20 workers simultaneously”.
  5. Appointment of Duty Holders (Principal Designer & Principal Contractor)
    The Client must formally appointment, soon as is practicable, a Principal Designer and Principal Contractor respectively when there is, or will be, more than one contractor on site and in any event before the construction phase begins.
  6. Replacement of the competency requirements.
    Under the 2015 regulations the explicit competence requirements have been removed and replaced with a requirement for appropriate skills, knowledge and experience.
  7. Transitional arrangements

    A transitional period will run for six months from 6 April 2015 to 6 October 2015.

    For projects starting before 6 April 2015, where the construction phase has not yet started and the client has not yet appointed a CDM coordinator, the client must appoint a principal designer as soon as it is practicable.

    If the CDM coordinator has already been appointed, a principal designer must be appointed to replace the CDM coordinator by 6 October 2015, unless the project comes to an end before then.
