Do you have a feel for which of these banks will expect, and to what degree? As someone that lives in two places (parent's home and rented accommodation) and has bills at the latter, and is a postgraduate student (i.e. on the fuzzy line between student and employee), but meets the other two points, I'm wondering if I fall between too many lines to be useful on the initial board.
I'm going to drop in on a few banks tomorrow (as a couple of people have already done, but the more we know the better) and will either talk to someone that knows about charity accounts or make an appointment for another time with each. One of the key things I'll be asking is about their requirements for trustees/signatories, so hopefully I'll be able to post a report with more info tomorrow evening. I'm in a similar position to you (although I'm actually back at my parents now and living in uni accommodation during term time). It sounds like WER only got as far as applying to one bank (Co-op), so others may have less stringent requirements, we'll see. If it turns out the elected board are unable to open a bank account, they do as much of the other stuff as they can and call an AGM and a new board with better credit histories can take over. It will delay things by a few months, but it's not the end of the world.
