- simpler to manage a UK limited from anywhere (we tend as a family to move quite a lot, so the limited is a fixed point for my customers.
- the German limited is not "limited" if you run it alone. If something goes wrong, as you run it alone, you lose defacto the limited liability.
So, all in all, better to go this way even if sometimes it costs more (2 accountants one in UK and one in Germany). As said, for me the goal was and is not to pay less taxes. I am happily paying taxes. If I pay a lot it means I make a lot :)
