When it comes to health and safety qualifications, two names often rise to the top: IOSH Managing Safely (IOSH MS) and NEBOSH. Both are respected certifications, but they serve different audiences and purposes. At ISTC, we regularly receive questions about which course is the better fit — so here’s a clear breakdown to help you make the right choice for your career or your team.

Understanding the Basics

IOSH (Institution of Occupational Safety and Health) offers the Managing Safely course, designed for managers and supervisors across all sectors. It provides a practical understanding of health and safety responsibilities in the workplace and focuses on equipping people with the tools to apply best practices in their daily role.

NEBOSH (National Examination Board in Occupational Safety and Health), on the other hand, offers a broader range of qualifications, with the most popular being the NEBOSH General Certificate. It is aimed at those seeking to start a dedicated career in health and safety or take on specialist roles.

So, how do you choose?

Key Differences

1. Target Audience

  • IOSH Managing Safely is ideal for managers, team leaders, and supervisors who need to understand safety procedures but are not necessarily health and safety professionals.
  • NEBOSH General Certificate is suited for those who want a career in health and safety or those in senior positions with substantial H&S responsibilities.

2. Course Content and Depth

  • IOSH MS focuses on the fundamentals: identifying risks, assessing hazards, understanding legal responsibilities, and improving safety culture. It’s concise and practical.
  • NEBOSH goes much deeper, covering subjects such as health and safety management systems, detailed risk assessment procedures, legal frameworks, and workplace hazards.

3. Course Duration

  • IOSH Managing Safely typically takes 3 to 4 days to complete.
  • The NEBOSH General Certificate requires 10 to 13 days of study, depending on the provider, and includes written assessments.

4. Assessment

  • The IOSH course concludes with a short multiple-choice exam and a practical project.
  • NEBOSH involves more in-depth written examinations and a formal risk assessment report.

5. Recognition and Progression

  • IOSH MS is recognised globally as a strong introduction to safety leadership.
  • NEBOSH qualifications are internationally recognised and are often a requirement for more senior or specialist roles in health and safety.

Choosing the Right Course

Choose IOSH Managing Safely if:

  • You are a manager, supervisor, or team leader who wants to understand and apply safety practices in the workplace.
  • You need practical, accessible training that fits into a busy schedule.
  • You want to raise safety awareness and compliance within your team without becoming a full-time H&S practitioner.

Choose NEBOSH if:

  • You’re aiming for a career in health and safety.
  • Your role involves developing or overseeing safety management systems.
  • You’re seeking qualifications to support progression into specialist or senior roles in the field.
