Professional Affiliates

A Professional Affiliate is an incorporated body or engineering institution closely associated with the Engineering Council. Professional Affiliates are influential and often work to further the knowledge and understanding of a particular area or aspect of engineering and technology. In addition to having access to key Engineering Council guidance, Professional Affiliates are also able to provide a pathway to professional registration for their members through setting up an agreement with a licensed professional engineering institution.

Information for potential members

The value of membership of a Professional Affiliate is similar to that of a professional engineering institution.  The difference is that Professional Affiliates are not licensed to assess candidates for professional registration.  However, many of them are able to offer their members the opportunity to become professionally registered, through an agreement with a licensed institution

For more information on any of the Professional Affiliates please contact them directly.

Information for eligible organisations

Professional Affiliate GuideThe value of Affiliation, for which you pay an annual fee, includes the opportunity to offer professional registration for your members through an agreement with an existing licensed institution.  Access to information becomes available for staff and members, through our Extranet, networks and annual seminars.  You also have the opportunity to contribute to industry developments.  Several Professional Affiliates have progressed to licensed institution status. 

Affiliation recognises the contribution your organisation makes in its fields of expertise.  It also provides the opportunity to see how your procedures and standards for membership are aligned with the UK Standard for Professional Engineering Competence (UK-SPEC).

More details on becoming a Professional Affiliate are available in the Professional Affiliate Guide.
