It is also important to note that a FRTOL License can only be issued if a language endorsement (of at least ICAO Level 4) is held. The UK CAA can only endorse with ICAO English after formal or informal assessment, though. Specifically people whose English proficiency falls below ICAO Level 4 cannot be issued with the FRTOL license. ICAO English ICAO Level 4 needs to be renewed every 4 years; ICAO English ICAO Level 5 needs to be renewed every 6 years.

ICAO English ICAO Level 6, on the other hand, is granted to pilots for life (and to Air Traffic Controllers for 7 years) - but it requires native or near-native proficiency.  https://www.caa.co.uk/General-aviation/Pilot-licences/Applications/Documentation/Language-proficiency/ * ICAO English Level 4 (OPERATIONAL): http://www.lab-106.eu/language-proficiency-level-4.php* ICAO English Level 5 (EXTENDED): http://www.lab-106.eu/language-proficiency-level-5.php* ICAO English Level 6 (EXPERT): http://www.lab-106.eu/language-proficiency-level-6.php
