Complaint letter builder

Create a concise factual complaint from a chronology, supporting records and a specific requested outcome.

Do not enter passwords, full payment-card numbers or unnecessary identity information. Check every result against the original record and the relevant official source.

Your working result

Complete the form above to create a working result.

Use the draft as a checklist

Every sentence should be something you can stand behind. Replace vague claims with dates and records. Remove accusations about motive unless you have a sound reason to include them. The strongest complaint is often the easiest one to verify.

Before sending

Check the recipient’s complaint process, attachment limits and escalation route. Keep the sent version and proof of delivery. The complaint letter guide explains the structure.

Quality check before you act

  • Compare the result with the original notice, receipt, form or decision.
  • Remove any generated wording that is not accurate.
  • Verify current forms, portals, fees and deadlines at the official source.
  • Save a dated copy of what you finally submit.
