It’s sad what’s happened there too (Co-op Bank). I felt uneasy after the hedge funds took them over - but as long as they have their ethical policy I think they’re legit.
The reason I left them in the end was because their on-line banking was so incredibly basic and bad. Until really recently you had to phone them to delete a payee. It was pretty much like a text-only website with about 2 functions (look at a list and ‘pay someone’). Now they’ve revamped it, it’s like a teenagers first attempt at Shockwave Flash.
I wanted to stay with them out of principle - just couldn’t hack it in the end. Their app was terrible and basic too, plus they still haven’t released Android Pay support more than a year after they released Apple Pay and a year or more of ‘we’re looking into it’ and ‘soon’.
All my insurance is with the Co-op - it’s such a chore, nothing is online. I’m sticking with that though because it’s all only once a year.
