Will they be open tomorrow?
I need to open a new account for my new job.
If I can open one tomorrow would they be able to give me the account number and sort code for payroll or would I have to wait for the paperwork? x

you usually need to wait for the paper work to come through. Banks will be open tomorrow yes though may not be normal opening hours

it depends which bank you go to, santander will give you an account number there and then
