Refund in case of double affiliation

In order to get a refund in case of a double social security affiliation (for example, fees paid at the University at the start of the semester, and a compulsory affiliation in regards to a student employment contract), you need to wait until the end of the semester.

• • For Winter Semester refunds, you have to wait until 15/02
  • For Summer Semester refunds, you have to wait until 15/09
• Email cns@secu.lu and ask for a “certificat d ’affiliation” from
  • “15/09 to 14/02” for Winter Semester fees
  • “14/02 to 15/09” for Summer Semester fees
• Forward us the document you received, within 2 months.
  • For Winter Semester refunds, request must be submitted to SEVE before 15/04.
  • For Summer Semester refunds, request must be submitted to SEVE before 15/11.
• Add your bank details : IBAN / BIC.
• We will then calculate the refund amount.

No late request or early certificate will be accepted.

You can then create a ticket on the Student Portal, under the "Social Security" tab and add the document to the request.

We will then calculate the amount of the refund and add you to the list.

Calculation rules :

• Minimum refund is 1 month.
• Winter Semester length is 5 months – 4 full months (October, November, December, January) and 1 “composite month” (last half of September and first half of February).
• Summer Semester length is 7 months – 6 full months (March, April, May, June, July, August) and 1 “composite month” (first half of September and last half of February).
• “Composite month” cannot be split.
• If the start of your work contract does not cover a full month, this month will not be refunded.

• • Example : A student who paid for CNS at Uni.lu for the full Winter Semester 15/09 to 14/02 and was covered by a job contract from 03/10 to 14/02 will receive the following refund :
    • 3 months (November, December and January).
    • October is not a full double affiliated month, so it will not be refunded.

We can not take the first half of February into account, as it must be calculated with the last half of September to be refunded as a “composite” month.
