Using your designatory letters

There’s something special about being able to use the designatory letters you’ve earned through being a member of the IET. To make sure you get the most from yours, we’ve put together this short guide of how and when to use them.

How do you use them?

You should use your Engineering Council letters after your decorations or degrees, and before your IET membership letters:

  • A B Smith OBE MEng CEng FIET
  • A B Smith OBE BSc IEng MIET
  • A B Smith OBE EngTech TMIET

Or you can use the title in full at the end, like this:

  • A B Smith OBE MIET Incorporated Engineer

If you pay your Engineering Council fees through another licensed member body, you must show the institution’s designation immediately after, like this:

  • A B Smith OBE CEng FRAeS FIET
