Most people know that you need a good credit score to be able to borrow money, but how to start building one is a mystery. First aired in June 2022, in this episode of Money Clinic, host and FT consumer editor Claer Barrett sits down with listener Emma, 22, who has never been in debt before, aside from her student loans. Emma has heard that getting a credit card could increase her chances of taking out a mortgage in the future, but before she applies for one, what does she need to consider? In this episode, Claer gives Emma’s credit score an MOT with help from Katie Watts, a consumer expert at moneysavingexpert.com, and debt adviser Sara Williams, who runs the Debt Camel blog. Together, they explain the hidden world of credit scores, credit files and tips on how to use credit responsibly, as well as offer tips on how to improve your credit score — and why this might be worth doing.
