Use of designatory letters
If you are entitled to use letters after your name through either your membership category or qualifications, please read our guidance on how to display your designatory letters.
Membership post-nominals
The table below shows you the designatory letters you may use according to your membership category:
Membership category | Post-nominal letters |
| Honorary Fellow | Hon FIET |
| Fellow | FIET |
| Member | MIET or TMIET |
| Associate | No permitted post-nominals |
| Student | No permitted post-nominals |
Professional registration (ECUK) post-nominals
Members and Fellows who are registered with ECUK and who pay their registration fee through the IET, may use the appropriate designation:
Title | Post-nominal letters |
| Chartered Engineer | CEng |
| Incorporated Engineer | IEng |
| Engineering Technician | EngTech |
How to display your designatory letters - best practice
The use of membership and registration designations applies to individual members only, and not to a firm or company to which one or more members may belong.
ECUK post-nominal letters should be used as letters denoting decorations or degrees and before letters indicating IET membership. Alternatively, the title can be used in full at the end. For example:
- A B Smith OBE MEng CEng FIET
- A B Smith OBE BSc IEng MIET
- A B Smith OBE EngTech TMIET
- A B Smith OBE MIET Incorporated Engineer
Members who pay ECUK registration fees via another licensed member body of ECUK must show the designation for the institution through which they are registered immediately after their ECUK designation. For example:
- A B Smith OBE CEng FRAeS FIET
