The Royal Environmental Health Institute of Scotland, often referred to as REHIS, was established in 1983 following the merger of the Royal Sanitary Association of Scotland (founded 1875) and the Scottish Institute of Environmental Health (founded 1973).  The Institute was incorporated by Royal Charter in 2001.

The Institute is a registered Scottish charity No. SC009406.

The Institute awards the qualification which allows a person to practice as an Environmental Health Officer (EHO) in Scotland. Under the Royal Charter and Scheme of Continuing Professional Development it awards Chartered Environmental Health Officer status to eligible members.

The Institute is a long established awarding body in Scotland for a variety of REHIS qualifications, many of which have been independently credit rated on the Scottish Credit and Qualifications Framework (SCQF).

The Institute is a founder Member of the International Federation of Environmental Health.

The objects for which the Institute is established, which are contained in its Royal Charter, are, for the benefit of the community to promote the advancement of Environmental Health by

  • stimulating general interest in and disseminating knowledge concerning Environmental Health;
  • promoting education and training in matters relating to Environmental Health;
  • maintaining, by examination or otherwise, high standards of professional practice and conduct on the part of Environmental Health Officers in Scotland.

Membership is open to all persons with an interest in Environmental Health in its widest sense.

The affairs of the Institute are managed by a Council, elected annually by members.
