I only had online account/statements but a quick call to the halifax/bank of scotland and they printed out all of my transactions in the usual statement format and sent to me in the post.
I also asked them for a letter confirming when my account was opened and the balance at the end of each month for the past year. That serves as confirmation in itself of what the statements contain.
I did the same sort of thing with Western union: Got a letter confirming all of my transfers from W Union in the States. (if you do it online/at the Dublin call centre they try and charge you).
