Or just fly without one!
My old lifetime one was replaced with a 5 or 10 year validity one at the time of JAR. Letter from CAA said there would be no charge for re-issue in 10 years. Once 10 years were up, contacted them for re-issue.
Yes, CAA has lost my Level 5 English. Yes, CAA wanted to charge me, and .... to gold-plate it, wanted proof that I had actually used it! When I asked how, they suggested a letter from my local ATC - Glasgow Airport!
I filed the correspondence and carried on, and will take my chances in front of the very wise Scottish sheriffs if ever needs be!
