I am young Brit, beginning my career as a scientist in Germany. Over the last few years I have accrued a sum which I wish to invest as long term savings, however the life of a scientist is one of regularly changing country (every 1-2 years). For this reason I wish to keep my savings in the UK as to avoid regularly paying fees for moving the money. This said, when looking for banks to invest with, it seems to be difficult to find those that will accept accounts for non-residents/ex-pats.
As someone living outside of the UK, how do I get started with investment in the UK?
