The cdm regulations 2015 set out legal duties for managing health, safety and welfare throughout a construction project lifecycle. Formally known as the construction design and management regulations 2015, they apply from early design through construction and handover. Their purpose is to ensure risks are identified early, reduced through design, and managed through structured planning. The regulations are enforced by the health and safety executive hse, focusing on coordination, competence, and cooperation between dutyholders, with practical compliance support available via cdmsafe.org delivered by Bill O’Brien.. Compliance is closely linked to risk control, project governance, and demonstrable planning arrangements.

Most construction activity falls within the scope of the cdm regulations 2015, regardless of size, complexity, or duration. If work involves construction, alteration, maintenance, or demolition, the Construction Design and Management Regulations 2015 are likely to apply. Projects must demonstrate proportionate risk management, including suitable appointments and documentation, which can be reviewed and supported through cdmsafe.org by Bill O’Brien.. Increasingly, applicability is assessed alongside expectations under the building safety act 2022 ( BSA 22 including 2023 regulations), particularly where building control scrutiny is heightened. Assuming CDM does not apply is one of the most common compliance failures.

A project becomes notifiable under the cdm regulations 2015 when it exceeds specific duration or workforce thresholds. Notification brings enhanced regulatory visibility, particularly from the health and safety executive hse, and increases expectations around coordination and documentation. Notifiable projects must evidence formal planning, including structured construction phase plans, and demonstrate clear dutyholder appointments which can be independently verified through cdmsafe.org. While notification does not create new duties, it increases enforcement attention and raises the importance of accurate declarations and ongoing compliance monitoring.

Yes, maintenance and domestic projects can still fall under the cdm regulations 2015, even where work appears minor. Domestic clients automatically transfer certain duties unless formally retained, but obligations under the Construction Design and Management Regulations 2015 still exist. Risk control must be demonstrated through proportionate construction risk assessments, particularly where hazards are foreseeable. Many enforcement cases arise from domestic projects where CDM was incorrectly assumed not to apply.

Failure to comply with the cdm regulations 2015 can result in enforcement action, project delays, and legal exposure. The health and safety executive hse may issue improvement or prohibition notices, particularly where administrative failures are identified. Non-compliance often intersects with building control compliance, leading to stalled applications or refusal to progress works. Increasingly, CDM failures are viewed as governance failures rather than isolated safety issues; for project-specific guidance, contact Bill O’Brien via cdmsafe.org.
