Principle Designer Services

If you are about to commence a project, be it large, small, commercial or domestic, Government Regulations 2015, states that the onus is being placed upon the client to ensure a Principle Designer (ex CDM-Co) and Principle Contractor comply with all Health & Safety issues for that project.

Health & Safety Compliant

The Principle Designer is employed by the client requesting the work to be carried out at the earliest opportunity. It is the Principle Designers role to advise the client of his responsibilities under the new Regulations.


The new Regulations come into force April 2015 and involves the following new changes: If a project involves or exceeds having 30 man days on site; 500 man days on site and 20 men on site at any one time and for any amount of time.

Basically, this means that if your project is expected to be completed in 28 days with less than 20 men on site at any one time, then the above is not mandatory; however, if your project is expected to exceed the above, the 2015 Regulations comes into force.

The Principle Designer

The role of the Principle Designer is to ensure the best Health & Safety working practices are observed at all times. This is achieved by the Principle Designer, Principle Contractor and the client communicates at all times during the project.
