Bank question and documents

I remember reading that with everything digitized, we only need to send copies of items. However now I’m seeing we also have to send them in via the mail? Is that the case? If so I’ve got a ton of printing to do.

Also my partner has been using Starling for his business and I wasn’t aware of this. I know we need to get print outs signed as we’re using our businesses as our income. However, Starling is a bank but doesn’t have any in person branches. What can we do? (We have an accountant doing our CT600s.)

Ah it looks like they send certified statements by mail.
