Belt, Braces and Bootstrap solution!Don't think that this is quite accurate. Though not a 'bank' any savings deposited monies held by them are lodged in a bank and hence covered by the FCA Deposit protection of £85k.
Monies used in the 'current' account ( the front facing account) are 'safeguarded' by way of being held in a bank account collectively. If the company is 'honest' ( yes the big question!) then all money they have of customers current accounts will reside in that safeguarded account which in the case of insolvency can only be depleted by the administrator for their costs before the customers take precedence over any other creditors. Hence a worst case scenario is that you'll get a very large percentage if not all of your current account funds.....
For our part we use Barclays to hold our funds and supply a credit card ( which is rarely used and mainly for hire cars etc) as well as an emergency debit card. It is only normally used to load £ onto our Starling card which has both £ and Euro accounts. We use this for large purchases and for loading our Revolute cards which seldom hold more than a day or twos funds and are what we use for most purchases and always on line. The philosophy is that the Barclays (except in emergencies) is never exposed to cloning / copying etc etc especially as it is via PIN pad while on line and normally never used elsewhere. The Starling is good for ATM cash withdrawals and big bills like apartment rentals etc as can pay direct to euro accounts etc etc and has no credit facility. So max exposure is what is on the card. The Revolute, is most exposed but has no overdraft facility and so is in real terms expendable if scammed in anyway as it usually only has a couple of hundred euros on at most..... it all seems to work so far!
(We broadly do something similar, except we don't have the Revolut card)
