Yeah as Tayub said, there's no way to defer this payment. It sucks I know, I also won't be getting my money through until the 17th. I was lucky enough to have just enough to cover my £250 damages deposit and the first four weeks, but for fresher's week i'll be skint! If you can't borrow from friends/family, ask in your bank about a student account. If I recall correctly barclays offer a £2000 interest free overdraft on student accounts, which should be more than enough to cover you until your loans come through.
