What happens after applying for CEng/IEng?

Information on what will happen once your application has been submitted.

Internal review

On receipt of your application for Chartered or Incorporated Engineer, it will be:

  • reviewed by staff;
  • reviewed by experienced and trained volunteers.

They will consider whether or not you have provided sufficient evidence for your application to progress to a professional review interview. You will be advised if any further evidence is needed.

The application process includes peer assessment by trained, experienced registered engineers who are IET members. These members are not IET staff, but volunteers who have been trained for this purpose. Please familiarise yourself with how we use your data.

Your interview

All applicants for CEng or IEng will be asked to attend a professional review interview (PRI). The interview is conducted by two registered members of the IET and you will discuss many aspects of your work which demonstrate your personal contribution and competence. At the start of the interview you will be asked to make a presentation lasting no more than 15 minutes and the overall interview will last approximately an hour. For further guidance, please watch this short video which will give you an insight into the process and what to expect.

The interview aims to confirm your overall level of competence and commitment as a professional engineer and you’ll be asked to expand on the information in your application.

Interviews can be held at various locations worldwide. If you have special requirements, please let us know so that appropriate arrangements can be made.


Successful applicants will receive a letter to confirm the decision, together with notification of Engineering Council fees which are collected by the IET on their behalf. Once we have received your payment, which should be within three months, your details will be submitted to the Engineering Council for registration. You will receive a certificate from the IET confirming your category of registration and date registered. Your registration number will be sent to you by the Engineering Council once the registration process is complete. Only upon receipt of your registration number will you be entitled to use the designatory letters CEng or IEng (as appropriate). You can find a list of newly registered members on our website.

Should your application be unsuccessful you will receive a letter advising you about the additional experience or knowledge required to address before you start a new application. You will also be referred to a Professional Registration Advisor who will be able to provide you with guidance and support. In some cases a different registration category may be recommended.
