Minimise risks, ensure compliance, and focus on building success with our CDM Principal Designer service

The Construction (Design and Management) Regulations 2015 (CDM) are serious business. Every year, thousands of UK construction projects fall under their scope. If a project involves more than one contractor—which is almost all of them—the client must appoint a CDM Principal Designer.

Fail to appoint one, and you automatically take on the role and its responsibilities. Non-compliance can lead to hefty fines, project delays, and, most importantly, preventable injuries. That’s where Spectra steps in to help.

We’re not just award-winning CDM consultants with 25+ years of construction experience — we’re your project’s guardian angel.

As your CDM Principal Designer, we dive into your project to understand its intricacies and potential hazards. We collaborate closely with your design team and appointed Principal Contractor to proactively manage risks throughout the design and construction phases.

Think of us as your safety compass, guiding you through the complex CDM landscape. We make sure your project meets all legal requirements while fostering a strong culture of safety within your team.
