Set up electronic payments today. I'm a FTB, just had an offer accepted and I'm being asked for proof of funds. I have the majority of my deposit saved in a Nationwide instant access cash ISA. My parents have asked me to show my bank statement. I have some transactions that I don't want them to know about. Branch, mini and online statements and Nationwide Bank Statements are all acceptable proofs but can't be used for proof of name or address. Nationwide is a building society rather than a bank but that doesn't stop it from stamping its own statements.
