CDM Regs 2015

HSE CDM Regulations 2015

The Construction Design and Management Regulations 2015 (CDM Regs 2015) are legal documents produced by the HSE. These set out what people involved in construction work need to do protect themselves from harm and anyone else the work affects

Where do the rules apply?

These rules do not only apply to large construction sites but to anyone engaged in commercial activity

You may be buying a property to do a quick flip, or to create an HMO or to renovate and extend to rent out. If so then these apply to you

Do not make the mistake of thinking that because you have appointed a builder to complete the works that he will take care of everything as it is not his responsibility

Also a lot of consultants and Project Managers will state in their terms and conditions that they will take no responsibility for CDM liabilities

Its essential you are aware of these when setting up a site

In 2018 there were 95 prosecutions under the CDM Regs and the average fine was £71,150

Here is what the HSE say


For all projects, commercial clients must:

  • Make suitable arrangements for managing their project. Enabling those carrying it out to manage health and safety risks in a proportionate way. These arrangements include:
  • appointing the contractors and designers to the project (including the principal designer and principal contractor on projects involving more then one contractor) while making sure they have the skills,knowledge,experience and organisational capability
  • allowing sufficient time and resources for each stage of the project
  • making sure that any principal designer and principal contractor appointed carry out their duties in managing the project
  • making sure suitable welfare facilities are provided for the duration of the construction work
  • Maintain and review the management arrangements for the duration of the project
  • Provide pre-construction information to every designer and contractor either bidding for the work or already appointed to the project
  • Ensure that the principal designer prepares a health and safety file for the project. Check that it is revised as necessary and made available to anyone who needs it for subsequent work at the site

For notifiable projects  (where planned construction work will last longer than 30 working days and involves more than 20 workers at any one time; or where the work exceeds 500 individual worker days)   commercial clients must:

  • Notify HSE in writing with details of the project
  • Ensure a copy of the notification is displayed in the construction site office
