This. My old gaffer had an account there. Even if you have the coin to be considered as a client they have your eyes out for fees, and the back office functions / online banking etc are just NatWest (and shite) with the designer label on top. One of many financial services designed for the stupid and insecure segment of the high net worth market.Coutts are expensive and rubbish imo
I use transferwise for forex transfers and they're great. You can also get a debit card with them and hold balances in each currency with them now, but it is not covered by FSCS, and there's a fee for holding euros due to negative interest rates.
I've always been with Barclays and they are nothing special but totally fine. I have heard nothing but good things about First Direct, Metro Bank and Handelsbanken from friends who are outside the big high street banks.
