Credit score myths debunked in the UK

Credit scores are widely misunderstood. Many commonly repeated beliefs about credit scores are simply wrong — and acting on them can lead to poor decisions. Here are the most common UK myths, debunked.

Myth 1: There is a universal UK credit score

False. Each of the three credit reference agencies — Experian, Equifax and TransUnion — produces its own score using its own model and scale. Lenders also apply their own internal scoring on top. Your score will be different on each platform, and there is no single "official" UK credit score that exists across all lenders.

Myth 2: Checking your credit score damages it

False. Checking your own credit report or score is a soft search and has no impact on your score whatsoever. You can check as often as you like through your credit reference agency or free services like ClearScore or Credit Karma without any negative effect.

Myth 3: Income and savings affect your credit score

False. Your credit score is calculated from your credit behaviour — borrowing history, payment record, utilisation. Income and savings are not part of your credit file. They are often requested by lenders separately as part of affordability assessment, but they do not directly affect the credit score number.

Myth 4: Your partner's credit score affects yours (unless you have joint products)

Mostly false. Living with someone, being married, or being in a civil partnership does not link your credit files. Credit files are only linked when you have a joint financial product — a joint bank account, joint mortgage or joint loan. If you have no joint products, your scores remain completely independent.

Myth 5: Closing old accounts improves your score

Usually false. Closing old, well-managed credit accounts often reduces your credit score because it shortens your credit history and reduces your total available credit (increasing your utilisation percentage). Unless an account has fees or is associated with problems, leaving it open (even unused) is generally better for your score.

Myth 6: Paying off a default removes it from your file

False. Paying a default marks it as satisfied, which lenders view more favourably — but it does not remove it from your credit file. The default remains for six years from the date it was recorded, regardless of when or whether you paid. The only way to remove accurate negative information early is if it was recorded in error.

Myth 7: Debit card usage builds your credit score

False. Debit card transactions are not reported to credit reference agencies and have no effect on your credit score. Only credit products — credit cards, loans, overdrafts, mortgages — appear on your credit file. Using a debit card responsibly says nothing to lenders about your creditworthiness.
