I am doing an enhanced MEng Undergraduate Degree


If you are doing a MEng that begins in the UK you do not need an ATAS certificate regardless of the JACS code.

However, if you are joining a MEng part-way through and have done the rest of your studies outside the UK then you may need an ATAS certificate. Please check to see if your JACS code is one of the ones on the Taught Masters list. If it is you need to apply for ATAS clearance.

Taught Masters JACS Code:

  • F2 – Materials Science
  • F3 – Physics (including Nuclear Physics)
  • H3 – Mechanical Engineering
  • H4 – Aerospace Engineering
  • J5 – Materials Technology not otherwise specified.

JACS Code:


To confirm whether you need an ATAS certificate or not, you will need the relevant JACS code that applies to your course. Your University will either include this on your official letter or will be able to confirm it separately. Please do not contact us to ask which JACS code applies to your course. Only your University will be able to tell you this information.

Do not guess at which JACS code is relevant your studies. If you register with the wrong JACS code you cannot change. Please ensure you have the right JACS code before you start your application.

What Next if you need to apply for an ATAS certificate?

If you are a new student:


You should only apply for an ATAS certificate AFTER you have received either a conditional or unconditional offer from a UK University. Please do not apply without this your application will be rejected.

Please also have details of your modules you will be studying to hand as you will need this to make your application.
