BOHS is the leading awarding body for qualifications in relation to health risk exposures in the workplace. As the Chartered Society for Workplace Health Assessment, we align our standards with the RQF and ISO.
BOHS awards Professional Qualifications under its Royal Charter and is responsible for the recognition of overseas professional qualifications under the Regulated Professions Act 2022. It is also the home of the UK’s Register of Occupational Hygiene Professionals, accredited by the Professional Standards Association for Health and Social Care.
As the only UK-based examining board for occupational hygiene, BOHS qualifications are internationally recognised by all leading employers and institutions. This includes the UK Health and Safety Executive (HSE), the UK Accreditation Service (UKAS) and the International Occupational Hygiene Association (IOHA).
As of December 2023, BOHS is implementing a new pathway to UK professional qualifications, replacing the OHTA W500 series. For further information on this, please see the M Series Candidate FAQs and the M Series Exam Centre FAQs.
BOHS exam systems are approved by the Construction Industry Training Board (CITB), the industry training board for the UK construction industry.
Accreditation and Endorsement
BOHS is also one of the 16 certification boards that belong to the National Accreditation Recognition (NAR) Committee. The NAR Committee exists to promote global respect for and recognition of occupational hygiene certification schemes which meet or exceed the IOHA Model Certification Programme.
To help raise standards and awareness among non-specialists and companies, we also endorse a range of partner courses on essential topics of worker health protection.
