We set up the independent Examining Board to certify the attainment of recognised standards of competence in the practice of occupational hygiene. Find out about our internationally recognised qualifications in occupational hygiene and allied subjects.
BOHS Qualifications
Our Proficiency qualifications are designed for those working in a specialist area at a practical level with the responsibility of monitoring, managing, and controlling risk in the workplace. The qualification codes start with a 'P'.
We also offer one day refresher courses for some qualifications, which start with 'RP'.
For candidates living/working outside of the UK, UK Proficiency qualifications are updated with reference to legislation fro different countries. The qualification codes start with 'IP'.
From 1st January 2025, BOHS no longer awards for, or recognises courses of, OHTA. BOHS certificated learning for W500 and ICertOH will continue to be recognised.
International candidates can study and be awarded occupational hygiene qualifications, based on our established and globally recognised standards. Please refer to International Qualifications M-Series FAQs - British Occupational Hygiene Society (BOHS).
BOHS is the UK’s recognition body for Occupational/Industrial Hygiene qualifications from overseas. To meet UK competency standards, you should also seek registration with BOHS if you intend to work in occupational hygiene in the UK for more than 6 months- Register of Occupational Hygiene Professionals - British Occupational Hygiene Society (BOHS).
If you have an Occupational Hygiene qualification from another jurisdiction, you should check for its recognition with membership@bohs.org.
