A Postgraduate Doctoral Loan has to be repaid. Interest will be charged from the day the first payment is made to the student. Interest will normally be charged at the Retail Price Index (RPI) plus 3%. RPI is a measure of UK inflation. It measures changes to the cost of living in the UK. During some periods, we may apply an interest cap to ensure that customers are not being charged a higher interest rate than the average found in the commercial market.
They’ll be due to start making repayments the April after they finish or leave their course, or the April four years after the beginning of their course, whichever is sooner. They’ll only start repaying when their income is over £21,000 per year, £1,750 a month, or £403 a week. But, if they’re overpaid they may be asked to make repayments earlier, including whilst they're in study and earning under the threshold.
If students have had a previous loan from SLC, they’ll continue to repay these loans at the same time. How much they’ll repay depends on when they started their undergraduate course.
