What Are SMSTS Certificates?
An SMSTS (Site Management Safety Training Scheme) certificate proves that a construction site manager or supervisor has completed the 5-day CITB course covering health and safety management on construction sites. The course covers legal responsibilities, risk identification and management, CDM duties, accident prevention, and working with the supply chain on safety matters. SMSTS is not a formal legal requirement, but it is considered essential evidence of competence for anyone managing construction work under the CDM Regulations 2015. Most main contractors and clients require SMSTS as a minimum qualification for site managers.
Why SMSTS Certificates Matter
SMSTS has become the baseline qualification expected of anyone managing a construction site. Without it, site managers struggle to demonstrate the competence required by CDM 2015, and principal contractors will not accept them in management roles on their sites. The 5-day course is a significant time investment, and letting the certificate expire (after 5 years) means taking a 2-day refresher before it lapses. For contractors, having SMSTS-certified managers is essential for winning work and satisfying pre-qualification requirements.

Frequently Asked Questions — SMSTS Certificates
What does the SMSTS course cover?
The 5-day SMSTS course covers health and safety law, CDM 2015 duties and responsibilities, risk identification and management, method statement preparation, managing subcontractor safety, accident investigation, environmental management, and leadership in health and safety. It includes practical exercises and a final examination.
Is SMSTS legally required for site managers?
SMSTS is not explicitly required by law. However, the CDM Regulations 2015 require everyone involved in construction work to be competent, and SMSTS is the industry-recognised standard for demonstrating site management competence. In practice, it is required by virtually every main contractor and client as a condition of appointment.
What is the difference between SMSTS and SSSTS?
SMSTS (Site Management Safety Training Scheme) is the 5-day course for site managers and supervisors with management responsibilities. SSSTS (Site Supervisors' Safety Training Scheme) is a 2-day course for supervisors and forepersons who do not have full site management responsibility. SMSTS covers a broader range of management topics and is the higher-level qualification.
