As of 13 August 2026, AI can challenge a default on your credit file.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open each of your current UK credit reports and save the page or document showing the default, including the lender name, balance and default date.
   2. Gather the relevant credit agreement, statements, payment confirmations, bank records, notices, debt-collection letters and previous complaints, and redact passwords and unnecessary personal information.
   3. Paste the prompt into a chatbot and add the report entry, evidence and correspondence in separate labelled sections, asking it to mark anything unsupported as [CHECK].
   4. Compare the chronology and every factual statement in the two drafted disputes against the saved reports and original documents, correcting names, balances, dates and account references.
   5. Send the factual dispute to the lender and separately to the credit reference agency using its current official dispute route, attaching only the evidence needed to support the point.
   6. Save the submissions, attachments and acknowledgement, then take the response and your evidence to a solicitor or debt adviser if the case is serious, disputed or unresolved.

   Prompt

   Help me prepare a factual complaint about a default recorded on my UK credit file. This is not professional advice, so do not make a definitive legal finding or tell me that the default must be removed. Use only the evidence I provide and mark every missing fact or unsupported claim as [CHECK].
   
   My objective: [WHAT I WANT CORRECTED]
   Credit reference agency: [NAME]
   Lender or creditor: [NAME]
   Account details, with unnecessary personal information redacted: [ACCOUNT DETAILS]
   What the credit report says, including the default date and balance: [REPORT ENTRY]
   What I believe is wrong: [EXPLANATION]
   Relevant agreement, statements, payment records and notices: [EVIDENCE]
   Correspondence and responses so far: [CORRESPONDENCE]
   Any change of address, payment arrangement, dispute, illness, fraud or other relevant context: [CONTEXT]
   
   Produce:
   1. A short chronology with each event tied to a source document.
   2. A list of the strongest factual points and the evidence supporting each one.
   3. A list of gaps, contradictions and documents I should obtain.
   4. A calm complaint to the lender asking it to investigate and correct any inaccurate data, without exaggerating or inventing facts.
   5. A separate, shorter dispute for the credit reference agency, explaining which entry is disputed and referring to the evidence.
   6. A checklist of what I must verify before sending, including names, dates, balances, account references and attachments.
   7. A plain explanation of when I should seek help from a solicitor, debt adviser or the Financial Ombudsman Service, without claiming that any particular route will succeed.
   Do not include my full account number, passwords or unnecessary special-category personal data. Do not cite a rule unless you can identify the official UK source I should check.
