American with German Licenses - EASA?

[LTCTerry]

While stationed in Germany 2011-2013 I earned a power license (easier because I had an American one, but it's "real" not "on the basis of") and a gliding license.

I also have a "BGA Gliding Lisense".

I'm looking for advice on how to turn these licenses from 2012 into EASA Part-FCL ones so I don't lose the effort/money I put into them.

Can/should I transfer the German paperwork to the UK so I can do all this ine English?

Thanks for your advice.
