Introduction

Letter writing remains a crucial part of the English curriculum in CBSE schools, especially for classes 9 to 12. Among various types of formal letters, the Letter of Complaint is frequently asked in exams and practical writing tasks.

A Letter of Complaint is written to express dissatisfaction or concern over an issue, product, service, or behavior. Whether it's a faulty product, poor service, or unethical conduct, this type of letter serves as a medium for students to learn how to voice their concerns effectively and formally. Understanding how to write it with correct format, tone, and structure is essential for scoring well and for real-life applications.

What is Letter of Complaint Writing?

A Letter of Complaint is a formal letter written to report a problem, express dissatisfaction, or seek redressal from an individual, company, school authority, or government agency. It highlights the issue clearly, provides necessary details, and often suggests or demands corrective action.

In CBSE exams, this letter type helps students build real-life communication skills while following a formal format.

Key Characteristics of a Complaint Letter:

  • Formal and respectful tone: Even while expressing dissatisfaction, the tone should remain polite and professional.
  • Specific issue addressed: Clear mention of the problem with details like date, product/service, etc.
  • Logical and factual information: Avoid emotional language; focus on facts and expected resolution.
  • Action-oriented: The letter should include a request or suggestion for action or compensation.

When Do Students Write Complaint Letters?

  • To the principal regarding classroom or campus issues.
  • To the editor about a civic issue.
  • To a company about defective products or services.
  • To municipal authorities regarding public inconvenience.

This letter-writing format is common in CBSE Class 9, 10, 11, and 12 English curriculum, appearing in both writing skills and comprehension sections.
