Our Code of Conduct covers the fundamental behaviours which all members are expected to abide by.

As a professional body, we promote high standards of ethical conduct among our members to:

  • Protect the members of the public
  • Protect IMechE members
  • Uphold the reputation of the Institution and the wider engineering profession.

Our By-laws and Code of Conduct are our ethical standards, which apply to all IMechE members. The Code of Conduct Instructions provide further guidance to the regulations.

Members are expected to refer to the Code on a regular basis and to act in accordance with the Code throughout their membership, whether in a professional or a personal capacity, irrespective of their grade, the professional role they fulfil, or the countries in which they practise.
