Re-doing an initial first class medical
 

Looking for some advice on what to do. Currently I have 1st class medical from the UK that expires in February. I am looking to start my PPL/CPL flight training in Poland.

Would it be better to just wait until the UK medical expires and re do a first class initial medical in Poland and get all my license's from there or is there another process I must go through? The reason for the change is because of the brexit uncertainty. Any advice here is greatly appreciated.
