How can I improve my credit score if I am not paying bills or rent?
Any kind of credit contract such as a mobile phone contract (could be SIM only or with a handset) would also help increase your number of accounts and demonstrate a track record of responsible management and repayments. If you have a Pay As You Go phone at present consider a SIM only contract with the same network, and if your parents currently pay for your phone consider if it would be worth switching it into your own name. Also make sure that you are registered on the Electoral Role at your permanent address and have at least a minimum payment direct debit set up on your credit card (even though you state you intend to repay in full) to make sure you don't forget a payment as this will disproportionately affect your score when combined with young age and few other accounts. Lastly ensure that you have a decent amount of "head room" on your rolling credit accounts like credit cards and aren't using more than 80% of the credit available to you through your monthly spending, if necessary by asking for an increased limit from your company (and then not using it).
