At Phoenix, we offer every all of the most sought-after health and safety qualifications. That includes a wide range of courses accredited by the National Examination Board in Occupational Safety and Health (NEBOSH) and the Institution of Occupational Safety and Health (IOSH). 

Some of the questions we receive most include “how long does an IOSH certificate last?” or “will my NEBOSH qualification expire?” Candidates and employers naturally want to know if they will need to do it again in a few years. 

NEBOSH and IOSH are everlasting, but always changing

The short answer is that your NEBOSH and IOSH qualifications never expire. Once you have passed the exam or assessment, your certificate is valid for life. 

However, the knowledge you gain on the course is a different matter. That evolves and requires regular updating. 

After all, the one thing everyone knows about health and safety is that it never stands still. The law continually evolves, new regulations are introduced, and the standards set by professional bodies change to keep pace with technology or culture. 

Update your knowledge

For all these reasons, both NEBOSH and IOSH strongly recommend that you enrol on a refresher course for the latest version of your qualification every 3 years. It’s the simplest way to remain fully aware of what has changed since you became qualified.

More importantly, it helps to ensure that health and safety practice within your workplace is compliant. The benefits of a positive health and safety culture are to enable everyone to work safely, stay healthy, and be as productive as possible. These goals are only achievable with a firm grasp of the latest rules, knowledge, procedures, and skills.

Health and safety legislation is constantly evolving, so the NEBOSH and IOSH syllabuses are renewed regularly to reflect any changes

If you’re unsure whether you need to refresh your knowledge or not, you can get in touch with our training and qualifications team, who will be able to advise you.

IOSH Managing Safely Refresher

Both organisations strongly recommend taking an updated course every few years. In some cases, you can take a shorter route with the IOSH Managing Safely Refresher Course.

NEBOSH Construction Conversion

At Phoenix, we also offer industry-specific courses, such as the NEBOSH Certificate in Construction Conversion. This training is suitable for construction industry candidates, who have completed the NEBOSH General Certificate in the past five years.

Ready to move up the career ladder?

Another reason you might want to update your knowledge is if you’ve taken on new responsibilities, perhaps by moving to a senior role. In that case, the first step is to check which next-level course is most suitable for your precise needs. Should you choose a NEBOSH or IOSH course, for example? 


That decision may depend on what your ambitions are and how you see your career developing. Will the NEBOSH National Certificate help to advance your health and safety career? Read our blog on what jobs you can aspire to with a NEBOSH qualification
