Some decide in hours and pay out within a day or two, especially if you connect your bank account through open banking. Speed usually costs more, so compare the total amount repayable.

What speed costs
Fast lenders take more risk with less information, so they usually charge more. A short term also means larger repayments. Always compare the total amount repayable, not just the monthly cost or the speed.
