CDM 2015 - Notifiable Projects

08 February 2015


On the 6th April 2015 the CDM 2015 Regulations came in to force. We've been asked what projects are notifiable under the new regulations, so here's a summary.


When is a project notifiable?


Regulation 6 of CDM 2015 sets out the duty that a Client has to notify the relevant enforcing authority of certain construction projects.

A project is notifiable if the construction work on a construction site is scheduled to last longer than 30 working days and have more than 20 workers working simultaneously at any point in the project or it exceeds 500 person days.

Where a project is notifiable, the client must give notice in writing to the Executive as soon as is practicable before the construction phase begins. The notice must contain:

  1. The date of forwarding the notice.
  2. The address of the construction site or precise description of its location.
  3. The name of the local authority where the construction site is located.
  4. A brief description of the project and the construction work it entails.
  5. Client contact details: name, address, phone number and email address.
  6. Principal Designer contact details: name, address, phone number and email address.
  7. Principal  Contractor contact  details : name,  address, phone number and email address.
  8. The date planned for the start of the construction phase.
  9. The time allocated by the client under regulation 4(1) for the construction work.
  10. The planned duration of the construction phase.
  11. The estimated maximum number of people at work on the construction site.
  12. The planned number of contractors on the construction site.
  13. The name and address of any Contractor already appointed.
  14. The name and address of any Designer already appointed.
  15. A declaration signed by or on behalf of the Client that the Client is aware of the Client duties under these Regulations.


The notice must be clearly displayed, and updated when needed, in the construction site office in a comprehensible form where it can be read by any Worker engaged in the construction work.
