UCAS payment

Hi UCAS applications are due tomorrow and i have filled up everything, i am just waiting for my referee to submit the reference. So i am a bit worried as to how i will pay because the banks are closed on weekends and tomorrow is already sunday -
So when my referee has complited the reference and i will have entered all the info for payment, will i even be able to send the application or do they wait untill they get the money transaction (because in that case they would get the money on monday which is to late)?

So i guess what i am aksing is : is it possible to submit your application on UCAS if you only fill up the bank account info, but the money hasn't been transferred to their account yet???

thank you so much

Are you applying for medicine or Oxbridge?

Application fees are paid online by credit or debit card, so it doesn't matter if banks are "closed".

You need to have money on your card in order to pay , if you don't you cant pay.
