The ppl I had was a CAA ppl,obtained in 1994,I had a TMG rating on it and used it with the same privileges as an EASA ppl,but with the EASA juggernaut in full swing I had to replace it with something European two years ago,I think the change over date had been April 2015 but was deferred a couple of times. During my last medical the ame asked what medical I wanted which was when the confusion started, he said he couldn't do a medical for the CAA licence,only a LAPL or EASA ppl,so I went LAPL after we discussed what type of flying I did, we decided an EASA was probably not required and the LAPL medical was going to go self certification at some point, the confusion with Brexit muddied the water a bit so I went the LAPL route which has been fine for me so far...
