Your score can be found on your credit report, which is a document you can access through any of the Credit Reference Agencies (CRAs). There are three main Credit Reference Agencies in the UK: Experian, Equifax and TransUnion. They each have different tools and apps to help you access your credit report and understand your score.
Experian’s is called CreditExpert, Equifax data powers ClearScore, and TransUnion give you access to the information they hold on you through Credit Karma. Each of the CRAs will assign you a credit score based on your credit history and their calculations. Each Credit Reference Agency uses a different scoring system, so you’ll have a different score with each provider. You should find, that if one agency says your score is “good”, the others will say the same, even though their scoring systems are each a little different.
