But for ships where voyage is less than 19 days the PLF is filled in prior to departure from UK. But at the moment although on the PLF .gov site they have all the words to tell you a test is not required after Feb 11th, if you are leaving UK prior, the shipping companies require a completed PLF which cannot be completed since you don't have a test reference number; as no test is required.

Its a bit chicken and egg !
