It’s not unusual to be eligible for revolving credit (where there is no fixed repayment plan e.g. overdraft, credit card) but not be eligible for the equivalent on a fixed term if the fixed term is sufficiently short that our affordability logic doesn’t think you can afford it. In addition to this we are more conservative on loans than on overdrafts (our credit risk models are trained on a min £3k limit).
Our loan decisioning is using our internal model for credit risk trained for giving out loans – we are currently doing a lot of work on overdrafts to move it across to our “new platform” and use an internal model for this as well. Once this is complete many people that are not eligible for overdrafts but are eligible for loans should become eligible for overdrafts.
