Are cpy statements available from the online banks?

Hi all,
Just a quick question pertaining to Rabo/NR etc. Do any/all of these banks provide original copy statements if requested? I'm thinking about the future when applying for mortgage topups etc. and the bank asks for 3 months bank statements-it would be nice to be able to show them why I've only got the bare minimum in my account by showing them the statemants from my savings account.

Thanks guys.
