Ok so assuming this cash was sent went hiddenoreo said it was sent 3.30pm yesterday. It was sent via faster payment. The cash still has not appeared in my account over night... Projects you mentioned the latest this usually takes is overnight.
Santander normally clear overnight.
If it isnt in by 11am then there definately is something wrong, I would give it a couple more hours personally, I have had payments clear between 9-11 if they do not clear overnight, but never any later.
