Re: Rental deposit account to incur a fee
I'd think that, sadly, the bank is probably within it's legal rights, in that the fine print of big companies often says, in effect, that they may change their terms and conditions unilaterally, at any point. And they have informed you correctly.
Having said that, I can certainly understand that you're not happy about it! I wouldn't be, either.
Whether or not the landlord has any obligation to ameliorate the situation? I don't know, but I'd recommend:
a) talking to your neighbours who rent from the same landlord and asking them if they already have come up with alternative arrangements
b) making a few enquiries with other banks, as to their charges for the same sort of account
c) asking your landlord (perhaps together with your neighbours, and definitely in writing) to work with you to transfer the deposit to bank X or bank Y that you've already found out about (= you save the landlord the work).
