The NEBOSH National Diploma in Occupational Health and Safety is the flagship NEBOSH qualification, and is the first UK vocational qualification to be developed specifically for health and safety professionals. Since its introduction in 1988 it has become established as the most popular qualification of its kind, with over 10,000 students having successfully gained the NEBOSH Diploma. There is also a NEBOSH International Diploma for those working outside of the UK.

The NEBOSH National 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.

Who Should Enrol on the NEBOSH Diploma?

A NEBOSH 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 as a safety and health practitioner 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, approximately equivalent to Level 6 (degree level).

Achievement of the NEBOSH General Certificate or direct equivalent prior to undertaking this Diploma course is highly recommended.

A Prestigious Qualification

Holders of the NEBOSH National Diploma may use the designatory letters "DipNEBOSH" after their name.

The NEBOSH National Diploma qualification meets the academic requirements to apply for Graduate Membership (Grad IOSH) 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 NEBOSH Diploma provides a sound basis for progression to MSc level. A number of UK universities offer MSc programs that accept the NEBOSH National Diploma as a full or partial entry requirement.

How is the NEBOSH Diploma Qualification Structured?

The NEBOSH Diploma syllabus is divided into four units

The NEBOSH Diploma qualification is divided into four units, each of which is assessed separately. The units can be taken in any order, but as Unit D is a written practical assessment, it is highly advisable to have completed and passed Units A, B and C first.

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

Frequently Asked Questions

How Long Does the Classroom NEBOSH Diploma Course Take?

The NEBOSH Diploma 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 to successfully obtain a NEBOSH Diploma. NEBOSH estimate this to be 257 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.

Exams and Assessment

Units A, B and C are each assessed by a 3 hour exam held on nationally set days in January and July each year. Whilst we are able to pay NEBOSH and call exams when we want for the Certificate-level qualifications, the Diploma exams must be taken at these specific times.

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 NEBOSH Diploma qualification all units must be completed within 5 years of enrolment. We recommend exams are taken together following the course.


On successful completion of the 3 exams and project you will receive an accredited NEBOSH 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 NEBOSH 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.

NEBOSH National Diploma Distance Learning

Studying the NEBOSH Diploma by distance learning

Whilst we would always recommend a classroom course as the best option for learning the information, passing the assessments and achieving the qualification, we realise that for some people, taking seven weeks out of the workplace will simply not be an option. Therefore, we also offer an the NEBOSH National Diploma course by distance learning.

As well as the flexibility to study the course in your own time when you want to, a distance learning course also enables you to make as much or little use of the internet and a computer as you want.

The course is conducted as a typical distance learning course using textbooks, written assignments and support over the telephone. There is also, however, a whole range of additional support and study materials available online to supplement your learning. These include live webinars, video tutorials, a discussion forum, interactive materials plus much more.


Support is provided throughout, with expert tutors being available by phone, e-mail, Skype or secure messaging. Although it might not be as good as having a tutor right there with you in the room, you will still have a good support system in place as you progress with your distance learning studies. There is also an invitation-only Facebook Group where students can discuss topics with each other and NEBOSH course tutors.


The Unit A, B and C exams comprise a 3-hour written exam each. These exams are currently held in London, Birmingham and Manchester. Unit D is a written practical assessment, completed in your own time, which involves a full health and safety audit/review of a company of your choosing. There are four submission dates throughout the year for Unit D.

Revision Workshops

There are also revision workshops available to attend, which are highly recommended. These are run in London, Birmingham and Staffordshire.

Cost and Additional Fees

The distance learning NEBOSH Diploma course costs £1,295.00 + VAT. This price does not include the exams/assessments, or the NEBOSH enrolment fee. These can be booked and paid for when you are ready to take them. They are currently priced at:

  • NEBOSH enrolment fee: £60.00 + VAT
  • Written exam (Units A, B and C): £135.00 + VAT each

Accredited Courses and Exams

For accredited health and safety qualifications which require an individual to successfully pass a number of examinations and assessments at the conclusion of the training, a key component of achieving the qualification will be actually passing these exams. If they do not pass, whilst they will still have learned a great deal of useful information on the course, they will not acquire the accredited qualification which was likely to be their primary reason for enrolling on the course in the first place.

This short article looks at NEBOSH Diploma intensive courses and why they are the best option and format for this course in terms of providing the maximum potential for passing the assessments.

The NEBOSH Diploma is a Comprehensive Qualification

Of all the health and safety qualifications available in the marketplace today, one of the most comprehensive and prestigious is the NEBOSH Diploma. This course requires seven weeks of classroom training, as well as approximately 257 hours of self-study, not to mention revision time. As such, there is a tremendous amount of detailed information which needs to be learned and knowledge acquired in order to pass what are widely considered to be amongst the toughest of health and safety exams.

The NEBOSH Diploma is deliberately intended not to be an easy course, which means that those who do successfully pass all of the exams and assessments will have achieved a highly respected and prestigious qualification.

With so much course content to learn, it is easy for vital information to be forgotten. The more time that elapses between learning it and the exam, the less the candidate is likely to remember. Quite often this can be the difference between passing and failing the assessment(s), and consequently not achieving the qualification.

A full time, intensive, block training course with exams soon after not only enables delegates to achieve the qualification in a short period of time, it also ensures that they go into all exams with the information taught on the syllabus fresh in their minds.

The Benefits of an Intensive Health and Safety Course

The NEBOSH Diploma is an extremely tough course, and is a big step up even from the NEBOSH General Certificate which in itself is a fairly demanding course, comprising two full weeks of training.

Whilst it may be tiring and require a large amount of commitment, dedication and self-discipline, an intensive NEBOSH Diploma course which teaches the syllabus on a full-time basis, along with the constant presence and support of a course tutor, will provide the greatest chance of success for delegates wishing to pass the assessments and achieve the NEBOSH Diploma qualification.


Achieving the NEBOSH Diploma qualification is difficult enough at the best of times, so the last thing you want to do is create extra hurdles and challenges for yourself. Just as trying to undertake the qualification by distance or e-learning ramps up the difficulty exponentially (see above), so too does trying to spread it out over a long period of time such as a couple of years, or trying to complete the units at weekends or one day a week.

This is usually done to try and accommodate work or personal commitments, but the extremely lengthy time period involved means that so much information taught at the beginning is lost and forgotten by the time of the exams. Not passing the exams equals no qualification, and a lot of time and money spent on not actually achieving anything.

Although it can be hard to accommodate and fit in a NEBOSH Diploma course around work commitments, if at all possible it is extremely advisable to complete an intensive NEBOSH Diploma course on a full-time basis, as not only does this get the training completed much quicker, but significantly reduces the likelihood of knowledge being forgotten before exams.
