Highly sought after by many organisations, the NEBOSH National Diploma in Health and Safety trains delegates to competently apply key legislation and health and safety practices to the work environment.
Since its introduction in 1980, it has become the most popular qualification of its kind with over 18,000 students having successfully gained the Diploma and is the first UK vocational qualification to be developed specifically for health and safety professionals. A brand new syllabus and format for this qualification was launched in 2021, with new style updated assessments as from July 2023.
The course provides an in-depth understanding of occupational health and safety. It covers the additional management skills along with in-depth reviews of risk management techniques, human factors along with workplace health issues and key safety risks. These skills can be applied to a range of sectors including healthcare, construction and facilities management.
Cambridge Safety offers this course as either face to face in our classroom setting in Hampton, Peterborough or as distance learning.
For 2026 we have introduced a new payment plan for our classroom courses.
Our latest DN2 results from November 2025 achieved a 74% pass rate, exceeding the national pass rate!
The updated 2023 version of the qualification consists of three units : DN1 Managing Health and Safety, DN2 Workplace Health Hazards, DN3 Workplace Safety.
