Principal Designer Role 

  • Are you running a busy design practice but need to ‘do’ Principal Design as an ‘add on?’

  • Do you want to offer a rounded service but don’t have the time to deliver Principal Design duties?

  • Are you unsure about what the duties of Principal Designer are and need help to fulfil them?

The CDM regulations (CDM 15) introduced the role of Principal Designer, which partly replaces the previous CDM Coordinator duties. The Principal Designer is responsible for the planning, monitoring and coordination aspects of designing health and safety into a construction project.  This includes considerations of the principles of prevention for:

Design | Construction | Handover | In use | Demolition

The Principal Designer is stated as being “the individual or business in control of the Pre-construction phase” and will usually, but not always, be passed to the lead designer of the construction project during the early stages such as RIBA 0 – 2.


It is common for Principal Designer duties to pass to the Design and Build Principal Contractor following award of the build contract.

How Better Safety can help

We can fulfil the duties of Principal Designer for your practice. The Health and Safety Executive (HSE) recognise many Principal Designers may not have the necessary skills or experience within their practice to take on various projects and could choose to appoint an external organisation to support them in carrying out their duties.

We have extensive experience of supporting principal designers with the new CDM 15 requirements.
Our projects range from Major Civils works with a value of £320 Million to Minor Repair works with a value of £10,000.
We apply our Three Core Principles to every project we undertake:

TIME | COST | QUALITY
