Ship or ship portable radio licence: terms and conditions

There is no end date on the "lifetime" ship radio licence but Ofcom will revoke the licence unless the licence is either amended or validated at least once every 10 years.

Although the licence "disc" is no longer issued, the licence, relevant Maritime Radio Operator’s Certificate of Competence and valid Authority to operate must be kept with or near to the licensed radio equipment where it is physically practicable to do so. These documents must accompany the radio equipment when the vessel is taken abroad.
