I’m straight up front, I’m doing it entirely for the switch bonus.
I find it incredibly funny that they consider me ineligible for their £250 overdraft facility 
When they do the CASS and carry over the money I have currently sat in my RBS account, they’ll see I’m more than financially viable. But then I couldn’t care less about an overdraft facility anyway and I’m glad they’ve rejected me on that score because it makes zero difference to me personally. The one thing about FD that is truly making me smile, is how they’re pushing their 1 percent interest on a savings account, save £300 a month for 12 months for a measly £19 interest, yeah, no thanks!
It could be that once in there with FD, because they are app only, I’ll stick with them. I’ve proved to myself over the last decade I have no requirement whatsoever for branch banking.
As for Chase, I know what I just recently said in the Chase thread, but now I’m seriously looking at when/if they introduce direct debits, I’ll manually swap over the two active d/d’s from my Starling account to Chase and then if Nationwide are still offering their own account holders to CASS into a new account for £125 or whatever, I might just bin Chase on a CASS, assuming of course they join the CASS scheme, and take the free money from Nationwide.
