Finding a mistake on your credit report can be a frustrating experience. A single error can cause a lender to reject your mortgage application or charge you significantly higher interest rates. Unfortunately, credit report errors happen frequently, and the responsibility for spotting them falls on you.

Credit reference agencies process millions of pieces of data every month. With such a vast volume of information flowing in from hundreds of lenders, administrative mistakes are inevitable. Sometimes a lender fails to update an account after you have paid it off. Other times, your file might be mixed up with someone who has a similar name or has previously lived at your address.

The Most Common Credit Report Mistakes

When reviewing your report, pay close attention to your personal details first. Ensure your full name, date of birth, and complete address history are entirely accurate. Even a minor typo in your postcode can cause significant problems because lenders use this information to verify your identity against the electoral roll.

Next, examine every financial account listed on your file. Check that all open accounts genuinely belong to you. Look for late payment markers on accounts where you know you paid on time. Verify that closed accounts are marked as settled with a zero balance. If you see a default or a County Court Judgment (CCJ) that you do not recognise, you must act immediately as these are the most damaging entries a credit file can contain.

Financial associations are another area to scrutinise carefully. If you have ever held a joint account or taken out a joint mortgage with someone who has poor credit, their financial behaviour can affect your score. If that relationship has ended, you can apply to have the financial association removed.

How to Correct an Error on Your Credit File

If you find a mistake, do not panic. You have a legal right to challenge it. The first step is to contact the credit reference agency directly and raise a dispute. They are legally obligated to investigate your claim within 28 days. During this period, they will mark the disputed entry on your file so lenders can see it is under review.

You should also contact the lender responsible for the incorrect data. Provide them with any supporting evidence you have, such as bank statements showing a payment was made on time, or a letter confirming an account was settled. If the lender agrees an error was made, they will instruct the credit reference agency to update your file.

If the lender insists the information is correct but you disagree, you can add a Notice of Correction to your file. This is a short statement of up to 200 words explaining your side of the story. Any lender who checks your file in the future must read this notice before making a lending decision. You can also escalate the matter to the Financial Ombudsman Service if you believe the lender is acting unreasonably.
