This is quite interesting. For someone like me (and by the sounds of it you) who uses their credit card for most of my spending, what makes me choose my current account provider?
I have 4 current accounts (+ some that I use for savings as they offer high rates on small amounts), and each of them is chosen for a specific purpose (cashback, interest, insurance).
But frankly the account that I consider my main account is with Barclays purely by historical accident. Yes, they also pay healthy cashback, and I actually quite like them, but my current account is so boring (1 salary a month in, 4 dd + 1 so a month out) that it really isn’t important enough for me to change, even if one day I stopped liking them, or they stopped paying cashback (in that case I’d just move my DD elsewhere) - I just don’t care cuz I hardly interface with my main current account
And I suspect that will apply to a large number of people. Particularly if you are doing most of your spending through credit cards, your current account becomes kinda boring.
