A minus score is more of a ‘status’ rather than your actual score. What this means might help you understand where you are with your credit score and report.
The -1 score status on your account means that Experian, our partner credit bureau, hasn’t got enough information to give you a score.
Have a score with others but not ClearScore
The Experian scoring system we're showing you is the most comprehensive. It means that if you don't have enough data in your credit file it won't give you a score. Other scoring systems that Experian and other credit bureaus use might give you a score even if you don't have active accounts. As the score is based on 0 data it's not a reflection on how lenders see you as a borrower.
No active accounts means lenders can’t see if you are a reliable borrower or not. There’s not enough credit information to show you a score. To improve this, you can start by building a credit history which will impact your score.
