How to Become a Principal Designer in the UK
Overview
The CDM Coordinator role was created by the CDM Regulations 2007 and abolished when CDM 2015 replaced it with the Principal Designer. The work itself still exists: construction health and safety professionals now practise as Principal Designers or CDM advisers, guiding clients, designers and contractors through their CDM 2015 duties. This guide covers that modern pathway, including the qualifications, experience and salaries that apply to Principal Designer and CDM adviser roles.

Frequently Asked Questions

The statutory CDM Coordinator role ended in 2015.

Many consultancies still advertise this work under the "CDM adviser" label.
How much do Principal Designers and CDM advisers earn?▼
Principal Designer and CDM adviser salaries vary by experience, project size and location. Typical employed ranges are around £35,000-£55,000, with senior consultants and freelance specialists potentially earning more.
Do I need a degree to become a Principal Designer?▼
A degree is not the only route. Construction experience, design or project knowledge, NEBOSH qualifications and recognised CDM 2015 training can all contribute. The right combination depends on the role and the employer or client.
Is there demand for Principal Designers and CDM advisers?▼
Yes, for the modern version of the role. Every project with more than one contractor must appoint a Principal Designer under CDM 2015, and clients frequently hire CDM advisers for support. Demand for qualified construction health and safety professionals remains strong.
Can I work freelance as a Principal Designer or CDM adviser?▼
Yes, some professionals work as freelance consultants. This offers flexibility but requires relevant experience, business skills and suitable professional indemnity insurance because the work carries significant responsibility.
