Be mindful of your overdraft
Every student has heard an overdraft horror story. Your flatmate is £1999 in debt with a mere £1 to spend on dinner with no prospect of exceeding 0 with their next payday, or a night out is cancelled at the last minute because a pint would break the bank. However, there are two types of overdrafts, and only one can significantly harm your credit score.
Unarranged overdrafts occur when you spend more money than you have, but some accounts have a pre-arranged agreement for situations like this. Many banks offer student current accounts that have a pre-arranged overdraft of various limits. Santander, for example, offers £1800.
This arrangement means that banks are more forgiving of overspending, as long as it is within the limit, and credit scores don’t drop quite as much. Make sure you do pay your overdraft off eventually, though, whether that be with your student loan or when you get your first grad job, as you can quickly find yourself in an endless cycle of debt.
