Everything you need to know about the SMSTS course (Site Management Safety Training Scheme). Covers content, duration, cost, exam format, and renewal requirements.
The Site Management Safety Training Scheme (SMSTS) is a 5-day training course developed by CITB (Construction Industry Training Board). It is the most widely recognised health and safety qualification for construction site managers and supervisors in the UK. Virtually every contractor, client, and principal contractor expects site managers to hold a valid SMSTS certificate.
The SMSTS course covers the legal and practical aspects of managing health and safety on construction sites:
The course runs over 5 consecutive days (Monday to Friday), typically 08:00-17:00. It combines classroom teaching, group exercises, case studies, and practical scenarios. Attendance for all 5 days is mandatory — missing any sessions means you cannot take the final assessment. Most providers offer both in-person and online (virtual classroom) options, though in-person is generally considered more engaging and easier to learn from.
SMSTS course fees typically range from GBP 350 to GBP 550 depending on the provider and location. London and South East providers tend to charge at the higher end. CITB Levy Grant: if your employer is registered with CITB and pays the levy, they can claim a grant of GBP 120 per delegate towards the cost. Some employers pay the full cost as professional development.
The final assessment takes place on Day 5. It consists of a core knowledge multiple-choice test (approximately 25 questions, 45 minutes) and a case study exercise where you must identify hazards and recommend control measures. The pass rate is high — typically 95%+ for delegates who have attended all sessions and engaged with the material. If you fail, most providers offer one free resit within 6 months.
The SMSTS certificate is valid for 5 years from the date of issue. Before it expires, you must complete the SMSTS Refresher Course (2 days) to maintain your certification. If you allow your certificate to lapse, you must retake the full 5-day course. Set a reminder for 6 months before expiry to book the refresher — popular providers book up quickly.
SSSTS (Site Supervisors Safety Training Scheme) is the 2-day equivalent for supervisors. SMSTS is for site managers and senior supervisors. If you currently hold SSSTS and want to progress to a site management role, SMSTS is the next step. You do not need SSSTS before taking SMSTS — you can go directly to SMSTS if your role requires it.
