You get priority support for telephone banking and you get a dedicated account manager (not sure if it's a fully accredited banker). You are automatically classified as one of the highest tiered customers for them and can get preferred rates etc. on many other services. Aside from HNW individuals, they also traditionally cater to "expats", which is a fancy British word for high income white collar professionals/digital nomads who either travel frequently or have foreign residencies for business. You can easily create accounts at overseas branches with same Premier privileges and (possibly credit history transfer too) and fund transfers between accounts are free, though I believe their conversion rates are not necessarily as competitive as a proper brokerage like Interactive Brokers. HSBC's premier service has been around long before the likes of Transferwise.
