Some people never pay back their student loan. Their income has to reach one of two levels.
Plan 1 loans will start being repaid once you earn over £18,330 a year.
Plan 2 loan repayments start once you earn over £25,000 a year.
I know people who went to university and got a degree but were working in admin with me on just £21K a year, so therefore only paying back the minimum.
I always thought the trigger income was £21 000, worth noting that you only pay back 9% of the money over that, a salary of £25 000 equates to a repayment of £30.00 per month
