If two bureau scores differ, open the underlying credit information reports and compare facts that can actually be reconciled: lender/account identity, ownership, sanctioned or credit limit, current balance, amount overdue, payment history/DPD, account status, closure date and enquiries. A concrete data mismatch is disputable evidence; a score gap by itself is not.
| What you see | What it tells you | Next step |
|---|---|---|
| Same accounts and history, different scores | Different proprietary scoring models can produce different outputs. | Do not invent an error threshold. Focus on whether the underlying data is accurate. |
| An account, balance, DPD or status differs | There may be a reporting/update mismatch. | Match the lender record and dispute the specific inaccurate field with the bureau/reporting institution. |
| An enquiry or account is unknown | Could be a partner lender, reporting-name mismatch or unauthorised activity. | Identify the legal lender and application trail; escalate quickly if you cannot match it. |
| A lender quotes a different score from yours | The lender may use another CIC, a different report date, or its own underwriting inputs. | Ask which report/date was used if that information is available; do not assume your consumer-app score is the lender’s decision score. |
