How to fix a bank error on your UK credit file
A wrong missed-payment marker, balance or account status can affect borrowing decisions. Correct it with both the organisation that supplied the data and the credit reference agency showing it.
Get a copy of the credit report showing the error, identify the exact account and month, and raise a dispute with the relevant credit reference agency and the bank or lender that supplied the information. The ICO says obvious inaccuracies should be taken up with both, with an ICO complaint possible if they will not correct them.
Capture the error before it changes
Save the report entry, including lender name, account status, balance and month. If August shows a missed payment but your statement proves the Direct Debit was received on time, keep both documents together.
Credit reports can update on cycles, so a screenshot alone is weaker than a dated statutory report or downloadable report plus the underlying bank statement.
Start with a dated baseline. Download the report that shows the wrong entry and match it against the bank statement, payment receipt or closure letter. Record the lender name, account reference, disputed month, amount and the exact status that is wrong before contacting either organisation.
Apply “Capture the error before it changes” to How to fix a bank error on your UK credit file with one simple record: the current bank rule, your account-specific fact and the next action that follows from them. If the bank later gives a different answer, you can compare like with like instead of starting the investigation again.
The bank and the credit reference agency have different roles
The credit reference agency displays information supplied by lenders and other sources. If the bank sent the wrong marker, the bank usually has to correct its data feed; the agency can also investigate a dispute on its system.
Contacting both avoids weeks of being bounced between them without a case reference.
Worked example: a lender reports a £120 payment as missed even though your statement shows the Direct Debit left on time. Mark the statement date, the credit-file month and any bank reference, then ask for that specific status to be corrected rather than sending a general request to improve your score. That is more useful than asking whether the product or process is good in general.
For how to fix a bank error on your uk credit file, cross-check the expected result against the actual result in the section 'The bank and the credit reference agency have different roles'.
Ask for a specific correction
Do not simply say your “credit score is wrong”. State that the September 2026 status should be “paid on time”, that the account should show closed, or that the balance should be £0. Attach the proof.
A consumer-facing score can change for many reasons; the factual account data is the part that can be verified and corrected.
Use a fixed sequence rather than repeated trial and error. raise the factual error with the bank, open a dispute with the credit-reference agency that displays it, attach the same evidence to both and keep each case number. Do not open repeated disputes with different descriptions because that makes the chronology harder to follow. After each step, record what changed and what did not.

If a lending decision was affected, keep that evidence too
Suppose a mortgage lender declined an application after seeing a false arrears marker. Keep the decline letter and dates. Correcting the file is the first priority, but the consequences may also matter in a complaint to the bank that supplied the inaccurate data.
Avoid repeatedly applying for new credit while a material error is unresolved, because extra hard searches can complicate the picture.
Timing can change the outcome. credit-file data is not always refreshed instantly after a bank accepts a correction. Avoid making unnecessary new credit applications while a material error is still being investigated, and check the next version of the report rather than assuming the correction has propagated everywhere.
Treat “If a lending decision was affected, keep that evidence too” as a check you should be able to prove later when dealing with How to fix a bank error on your UK credit file. Keep the relevant figure or status and the date you checked it. If support is needed, lead with that evidence and the outcome you want rather than a long reconstruction.
Escalate persistent inaccuracies
The ICO states that if you have contacted the credit reference agency and original lender and there is an obvious inaccuracy they will not correct, you may complain to the ICO. A financial complaint about loss or poor handling may also fall within the Financial Ombudsman’s remit.
Keep one chronology showing report, dispute, bank response and corrected report.
If the normal route fails, switch from retrying to evidence. if the bank accepts the evidence but the entry remains wrong, ask which reporting field was amended and when it was sent. If the bank rejects the complaint, keep the final response together with the report, statements and dispute correspondence so the disagreement can be reviewed as one evidence pack.
Before relying on “Escalate persistent inaccuracies” for How to fix a bank error on your UK credit file, capture a dated baseline. That may be a statement entry, app status, tariff figure or support reference. A dated baseline makes later changes easier to explain and gives the bank a precise issue to investigate for “Escalate persistent inaccuracies” on How to fix a bank error on your UK credit file.
Frequently asked questions
Should I dispute the error with the bank or the credit reference agency?
Usually both. The bank may be the source of the data and the agency is displaying it.
Can I get a credit report without paying?
Yes. The ICO notes that statutory credit reports can be obtained without a fee.
Should I focus on the score number?
Focus first on the inaccurate factual data - payment status, balance, account ownership or dates - because that can be evidenced and corrected.
Worked example: If a bank reports a missed payment for March even though your statement shows the Direct Debit was taken on time, assemble the evidence before arguing about your 'score'. Keep the bank statement, the lender account statement, the credit-report entry and any correspondence that identifies the disputed month and account.
Ask the bank to correct the underlying data it supplies to the credit reference agencies, not merely to reassure you that the account is fine internally. A correction can take time to flow through reporting cycles, so check the relevant credit files again after the bank says the amendment has been submitted.
If you are about to apply for a mortgage or other important credit, tell the lender or broker that a documented dispute is in progress rather than assuming the error will disappear before underwriting. Keep a dated record of every complaint reference and correction confirmation so you can show the sequence clearly if escalation becomes necessary.
Use one closing decision rule. the job is finished only when the account status, balance and payment history are correct on the report you actually use. Save a copy of the corrected report and the bank confirmation, especially if the error previously affected a mortgage, loan or tenancy decision.

A credit-file complaint is strongest when it is almost boring: one account, one wrong field, one piece of proof and one requested correction. Fix the data first; then deal with any financial consequences caused by the error.
