When a court says something is "final" that means that it will not be revisited at that level. It does not mean you can't appeal. However, you can only appeal to the UK Supreme Court if you get permission from the Court of Appeals or the Supreme Court, and I doubt this is the sort of thing where such permission will be forthcoming.
The EU is not one country and does not have a unified judicial system like in the U.S. The decisions of the Court of Appeals of England and Wales (not the UK) have little precedential value in Germany and vice versa.
