NEBOSH Diploma in Occupational Health and Safety

The NEBOSH National Diploma Qualification

The NEBOSH National Diploma in Occupational Health and Safety is one of the most comprehensive NEBOSH qualifications available, and is the first UK vocational qualification to be developed specifically for health and safety professionals. Since its introduction in 1988, this accredited health and safety training course has become established as the most popular qualification of its kind, with over 10,000 students having successfully gained the Diploma.

A NEBOSH Diploma provides the core health and safety knowledge (transferable across industry, commerce and the public sector) which, combined with understanding and appropriate application, underpins the competent performance of an occupational health and safety practitioner.

The qualification is divided into four units, each of which is assessed separately:

  • Unit A: Managing health and safety
  • Unit B: Hazardous agents in the workplace
  • Unit C: Workplace and work equipment safety
  • Unit D: Application of health and safety theory and practice

  • Units A, B and C are each assessed by a 3 hour exam held on nationally set days in January and July each year. Unit D is assessed by an 8,000 word workplace-based project which is submitted to NEBOSH in March or September of each year. You can take your exams together or spread them over a period, but to achieve the full qualification all units must be completed within 5 years of enrolment. We recommend Diploma exams are taken together following the course.

    Holders of the NEBOSH National Diploma in Occupational Health and Safety may use the designatory letters "DipNEBOSH" after their name.

    The qualification meets the academic requirements to apply for Graduate Membership (GradIOSH) of the Institution of Occupational Safety and Health (IOSH). This is the first step to becoming a chartered health and safety practitioner as a Chartered Member of IOSH (CMIOSH). It also accepted by the International Institute of Risk and Safety Management (IIRSM) as meeting the academic requirements for full membership (MIIRSM). The National Diploma provides a sound basis for progression to MSc level: A number of UK universities offer MSc programs that accept the National Diploma as a full or partial entry requirement.

    Holders of the NEBOSH Diploma qualification are highly regarded by potential employers, with many high-level health and safety jobs requiring candidates to hold a NEBOSH Diploma before being considered. Achieving this qualification can therefore provide a tremendous boost to you future career prospects in the health and safety industry.

    Who Should Attend?

    The NEBOSH National Diploma is the qualification for aspiring health and safety professionals, building directly upon the foundation of knowledge provided by the NEBOSH General Certificate. It is designed to provide students with the expertise required to undertake a career in health and safety and also provides a sound basis for progression to postgraduate study.

    There are no formal entry requirements for the NEBOSH National Diploma, however candidates should consider that this is professional level qualification, and one of the most comprehensive and prestigious of all health and safety training courses, approximately equivalent to Level 6 (degree level). Achievement of the NEBOSH General Certificate or direct equivalent prior to undertaking the Diploma course is highly recommended.

    Need a health and safety qualification that isn't as comprehensive or extensive as the NEBOSH Diploma? Why not consider a NEBOSH General Certificate, IOSH Managing Safely or CITB SMSTS course?

    Course Material

    Delegates are issued with 3 official NEBOSH study books to use during the course and take away and keep for future reference. The course and materials are designed to be highly interactive, allowing delegates the opportunity to develop their skills with the support of the course tutor.

    Course Tutor

    Our health and safety consultants are highly qualified and experienced professionals with a background in delivering engaging and effective health and safety training. All trainers hold Chartered or Graduate membership of the Institution of Occupational Safety and Health (IOSH).


    The course will be delivered over 35 days in total, delivered in blocks of one week (a total of 7 weeks spread over 4 months).

    As well as the 35 tuition days, candidates should be aware there is a significant element of private self study required. NEBOSH estimate this to be 225 hours spread over the duration of the course; however this will vary from candidate to candidate depending on past experience and knowledge.

    There is an optional 3 day revision module held at the completion of the course and prior to the exams, which can be booked either at the time of booking or at any time during your course.


    On successful completion of the 3 exams and project you will receive a NEBOSH accredited qualification: the NEBOSH National Diploma in Occupational Health and Safety. All exams are marked externally by NEBOSH appointed examiners.

    To acknowledge the achievements of successful Diploma candidates, NEBOSH hold an annual graduation and awards ceremony. Eligible Diplomates will be invited to book a place at this prestigious event in April or shortly after your results are issued.

    Is the NEBOSH Diploma suitable as an online or distance learning course?

    No. A NEBOSH Diploma is one of the most comprehensive health and safety qualifications available in the world, which means that there is a tremendous amount of detailed information which needs to be absorbed in order to pass the assessment at the end. The NEBOSH National Diploma classroom course comprises 35 days of training with a recommendation of approximately 225 hours of self-study required throughout the duration of the training.

    At ATC Risk Management we trialled different forms of learning and thought long and hard about offering the NEBOSH National Diploma qualification as an online or distance learning course but decided firmly against it in the end. This is because the pass rates are so much lower as many people struggle to not only take in all of the required information without the support of a course tutor, but also to understand how this knowledge needs to be used in order to pass the assessment. It can also be a tough ask to learn the information with all the distractions that are likely to be present when not in a dedicated learning environment (see picture above for an example!).

    At ATC Risk Management we care more about delegates passing the assessment and gaining the qualification than taking their money off them. With over 30 years of experience, we are one of the UK's most trusted health and safety training providers which is a key factor in us being at the top of the Google organic search results for many health and safety searches. You will often find other providers, particularly those in the expensive advertising positions on Google who are desperate to take your money no matter what so that they can cover their advertising costs, who will offer e-learning or distance learning NEBOSH Diploma courses at extremely low rates. We have lost count of the number of people who have spent money on an e-learning or distance learning course only to find out once it is too late that it would be far better to attend a classroom-based course. Please do not become one of them.


    We run the NEBOSH Diploma as a full-time, classroom course as this provides the highest pass rates for this difficult and comprehensive qualification. The course comprises 35 days of training followed by 3 days revision (optional) and 3 exams (of 3 hours each) spread over 3 days (exams are held on NEBOSH nationally set dates in January or July). A project is completed in the candidates own workplace and submitted in March or September.

    Unit A, B, and C are assessed by a 3 hour exam each held on a separate day.

    Unit D (the project) is an 8,000 word report completed in the candidates own workplace and submitted to NEBOSH for marking in March or September. There is a fee for this unit (included in the examination fees below).

    Scheduled NEBOSH National Diploma Dates

    We currently run NEBOSH National Diploma courses at our Nottingham head office in the East Midlands. Please see below for scheduled dates.

    Delegates need to complete Units A, B, C and the Unit D project/report in order to obtain the NEBOSH Diploma qualification, however it is not necessary to start with Unit A as each are separate modules. This means that those wishing to enrol on the NEBOSH Diploma course do not need to wait until the first Unit A date to begin.
