A sudden fall in an app score is a signal to inspect your credit report, not proof that you have become a bad borrower overnight. The change may reflect a new balance, account update, search, missed payment, address issue or an alteration to the agency’s scoring model.
Common explanations
- A card balance or credit utilisation increased.
- A payment was reported late or missed.
- A new hard search or account appeared.
- An older account was closed.
- Electoral-register or address data changed.
- A default, County Court Judgment (CCJ) or financial association appeared.
- The agency changed its score scale or model.
What to do first
Open the full report and compare it with the previous version if available. Then check the other Credit Reference Agencies (CRAs). Focus on new or changed records rather than the headline number.
If nothing looks different
The displayed score can change even when no negative event is obvious. Ask the provider to explain its stated factors, but remember lenders do not simply buy the score shown to you. They use their own policies, information and affordability assessments.
If you find an error
Save the report, gather evidence and complain to the data supplier and agency. The Information Commissioner’s Office (ICO) explains the right to correct inaccurate personal data. Do not pay a third party to challenge an error you can dispute yourself.
