Principal Designer CDM vs Principal Designer Building Regulations

Principal Designer CDM vs Principal Designer Building Regulations: What’s the Difference? 

If you’re planning a construction project in the UK, you’ve likely come across the term ‘Principal Designer’. But did you know there are now two different roles with this title? One is appointed under the CDM Regulations 2015 and the other under the Building Regulations following the Building Safety Act 2022. This guide explains the difference between the Principal Designer (CDM) and the Principal Designer (Building Regulations), helping you understand when each is required and what their duties involve. 

What is a Principal Designer under CDM Regulations 2015? 

The Principal Designer (CDM) is a duty holder under the Construction (Design and Management) Regulations 2015. This role focuses on planning, managing, and coordinating health and safety during the pre-construction phase of a project. If a project involves more than one contractor, the client must appoint a Principal Designer (CDM). 

Key duties include: 

– Managing health and safety risks in design.
– Ensuring cooperation between designers and contractors.
– Providing relevant information to other duty holders.
– Advising the client on their CDM duties. 

What is a Principal Designer under Building Regulations? 

Introduced through the Building Safety Act 2022, the Principal Designer (Building Regulations) is responsible for ensuring that building designs comply with the Building Regulations. This role is required for any project involving design work subject to Building Regulations approval. 

Key duties include: 

– Ensuring compliance with all relevant parts of the Building Regulations.
– Managing and coordinating the work of all designers on the project.
– Providing compliance declarations to the Building Safety Regulator for higher-risk buildings.
– Maintaining design records and documentation. 

Key Differences Between the Two Roles 

Although the job title is the same, the responsibilities, legal basis, and project triggers for each Principal Designer role differ significantly. 

Can One Organisation Fulfil Both Roles? 

Yes – provided they are competent in both areas. Many architectural and surveying practices are able to take on both responsibilities, but they must clearly distinguish and fulfil the specific duties of each role. 

Why Appointing the Right Principal Designer Matters 

Failure to appoint the appropriate Principal Designer, or confusing the two roles, can lead to serious project delays, enforcement action, or regulatory breaches. With increased focus on building safety, it’s crucial to ensure the right appointments are made early in the project lifecycle.
