The ATPL theoretical knowledge examinations will remain valid for the issue of an ATPL for a period of 7 years from the last validity date of an IR entered in the license. If a UK-ATPL license holder had a valid IR on December 31 2020, he/she may have an ATPL license issued until December 31 2027 based on these examinations. E.g. for a UK-ATPL license holder (former EASA license holder), whose IR expired on June 30 2017, the last date to have an EASA ATPL license issued will be June 30th 2024.
