... did they allow you to use a statement downloaded from a 'paperless' account?
I needed to verify my ID and nominated current account details for opening a savings account at a building society. They wouldn't let me use a downloaded bank statement for this. Instead they said they wanted an "original" statement, meaning the same statement but printed by my bank, not by me. However, they also said they would accept a post-office certified copy of the bank statement. So, I took 2 printed copies of my downloaded statement to the post office, had one certified as a copy of the other (costing £12.75 ), then sent the certified copy to the building society. They accepted that ok, which just seems bonkers! 🤷
