What is the Register of Occupational Hygiene Professionals?

The Register of Occupational Hygiene Professionals is administered by the Faculty of Occupational Hygiene, the Professional Standards Body for the British Occupational Hygiene Profession.

Whether you are employing someone to provide occupational hygiene advice in-house or have employed the services of a company, you need to check that the person giving you advice is  competent to do so. 

The Register enables you to check an individual’s level of expertise and to see whether they have been independently verified as meeting the requirements outlined in Regulation 7 of the Management of Health and Safety at Work Regs 1999'. If they are not on the Register, even if they are registered with another professional body, then there has not been an independent check of their training, experience and other attributes. It is your duty to ensure that you have undertaken appropriate due diligence to verify these matters yourself.

The Register is a voluntary statutory register. That means that the Register is maintained under strict conditions. It is possible for a person to provide services without being registered and without it being unlawful, but such an individual would need to be able to evidence their competence, training, and attributes. A user of their services would need to demonstrate that they undertook due diligence to ensure that they were a competent person in accordance with Regulation 7 of the Management of Health and Safety at Work Regulations 1999.
