Incorporated Engineer

The Nuclear Institute holds a licence from the Engineering Council to register professionals as Incorporated Engineers:

Professional registration as an Incorporated Engineer (IEng) recognises your proven competence, commitment, skills and experience. It is an important milestone in the career of any engineer or technologist. In particular, IEng registration shows your employer and peers that you have demonstrated a commitment to professional standards, and to developing and enhancing your competence. Do you:

  • maintain and manage applications of current and developing technology?
  • apply existing and emerging technology in your work?
  • solve engineering problems?
  • contribute to continuous improvement in your business processes?
  • manage the planning, budgeting and organisation of tasks, people and resources?
  • have involvement in design, development, manufacture, construction and operation?

If the answer is yes, then you deserve to see your professionalism recognised – by gaining the title Incorporated Engineer.


  • Recognition that you are a professional
  • Identifying that you have the competences, expertise and work ethics that employers value
  • High status and self-esteem
  • Improved career prospects
  • Greater influence within your organisation and industry
  • Higher earnings potential
  • Access to life-long learning
  • Being part of a network of professional engineers
  • International recognition of your professional qualification
  • Demonstration that your competence may be compared with standards applicable in other parts of the world
  • Letters after your name eg J.Smith IEng
  • Your employer will also benefit as increasingly, tendering or post-tender contract compliance requires key members of the project team to be professionally registered.


The IEng professional qualification is attainable by anyone who can demonstrate the required professional competences and commitment (See Form MF3). These are set out in our professional standard, UK-SPEC, and are generally developed through education and working experience.
