What to check on your credit reports before a mortgage application

How can I get my credit reports for free?

You can request a free statutory report from each credit reference agency. MoneyHelper currently lists Experian, Equifax, TransUnion and Crediva; their files can differ. The direct routes are linked below. A free score-only service is not necessarily the full report. Checking your own report does not lower your credit score. Keep the date and agency alongside each copy so you know which record you are discussing.

• Use the agency's statutory-report route if you only need the file, rather than assuming a paid subscription is required.
• If a previous lender identified the agency it used, include that report in your checks.
• Compare the underlying entries across reports instead of comparing score numbers on different scales.

What should I check in my address history?

Build a simple chronology of where you actually lived, with move-in and move-out dates, flat or house numbers and postcodes. Use the history requested by the application, not a guessed universal look-back period. Check that the application, reports and supporting documents are consistent. A genuine previous address link is not automatically an error and should not be removed simply to make the file look cleaner.

• Check spelling, previous names and full addresses, particularly flat numbers and similar postcodes.
• Explain temporary accommodation, overseas periods or gaps accurately if they are relevant to the history requested.
• Investigate an address you do not recognise: ask the agency where the link came from.
• Correct genuinely wrong information; keep an explanation for genuine history that may be confusing.

Check accounts, payment history and financial links

Work through each entry rather than stopping at the summary score. Create a short list of anything you cannot reconcile with your own records. A joint account or borrowing can create a financial association; sharing an address alone does not establish that all of someone else's borrowing is yours. Ask the relevant agency about any association you believe is wrong or no longer appropriate.

• Accounts you do not recognise, duplicated entries or details that appear to belong to someone else.
• Balances and account status that do not match your latest records, allowing for the report's update date.
• Missed-payment, default or court information you believe is inaccurate, with evidence of why.
• Credit commitments and associations that need to be explained alongside your mortgage application.

How do I correct an error on a credit report?

Identify the exact entry, agency and reporting organisation. The ICO explains that you can raise an inaccuracy with the agency, although the original information provider may need to correct it. Keep supporting evidence and the complaint reference. Ask what happens next and recheck the entry afterwards. Accurate adverse information does not become inaccurate because it is inconvenient for an application.

• Describe the specific error and the correction you are requesting.
• Keep copies of relevant correspondence and a dated record of the response.
• Use the organisation's complaint route if the matter remains unresolved.
• For an unresolved personal-data accuracy issue, see the ICO guidance linked below; a separate dispute about whether a debt is owed may need another complaints route.

Worked example: a linked address you do not recognise

Imagine that your report lists Flat 2 while your records show you lived in Flat 12 at the same building. First check whether the link comes from your own account, a joint account or an incorrect entry. Compare the address with dated tenancy or account correspondence. Ask the agency to explain the source and request a correction if the link is wrong. Keep the reference and recheck the file before treating the issue as resolved. This is a fictional preparation example, not evidence that an address mismatch caused a mortgage decline.

• The fact to resolve: which flat number was recorded, by whom and for what period?
• Useful evidence: the dated document supporting the correct address.
• A useful outcome: corrected information or a clear explanation of a genuine link, recorded with the agency's response.

Which searches and recent applications should I review?

Your own report check is different from applying for new borrowing. Review recent application searches and accounts you have opened, and query searches you do not recognise. Before a mortgage quotation or agreement in principle, ask whether the particular process involves a soft or hard search. Do not assume that every lender uses the same process or make extra applications simply to test acceptance.

Prepare a factual summary before discussing a mortgage

Separate confirmed facts, unresolved errors and genuine history requiring explanation. A concise chronology gives an adviser a more useful starting point than a statement that your score is low. If an application is urgent while an important discrepancy remains unresolved, explain that before proceeding; a report correction does not guarantee acceptance or determine a lender's criteria.

• Report agency and date, with the entries you want to discuss.
• A consistent address and name history for the period requested.
• Current commitments, recent applications and expected changes.
• For genuine adverse history: what happened, when, the amount and the current status.
• For disputed entries: the evidence, complaint reference and latest response.
