By this time we all know that payment protection on loans is charged as a one-time premium at the time when the loan is originated. In other words, if you take out a loan for £100,000 and you are charged payment protection cover at the rate of 23% then you would actually be taking out a loan for £123k. It’s quite noticeable and something easy to detect, but payment protection cover on credit cards is a bit trickier because it is only charged on an outstanding balance carried forth from the previous month. As a result, that amount changes from month-to-month even though the percentage being charged remains the same. This is one of the most difficult types of PPI to calculate when requesting a refund on mis-sold PPI. Contact The Payment Protection Claims Company the find out more.
