- ✔ The Principal of a school
- ✔ A newspaper editor
- ✔ A government official
- ✔ A company or organization
- ✔ A municipal authority
- ✔ A public representative
ICSE Formal Letter Format
A formal letter should follow a clear structure. The main components include the sender's address, date, receiver's address, salutation, subject, body, complimentary close, and signature.
- Sender's Address
- Date
- Receiver's Address
- Salutation
- Subject
- Introduction
- Main Body
- Conclusion
- Complimentary Close
- Name and Signature
1. Sender's Address
Write your address at the top of the letter. In an examination, use a fictional address rather than your personal home address.
Example:
24, Lake View Road
Kolkata – 700029
2. Date
Write the date below the sender's address. Avoid unnecessary abbreviations.
Example:
25th July 2026
3. Receiver's Address
Write the name or designation of the person receiving the letter, followed by the organization's address.
Example:
The Editor
The Daily Chronicle
Kolkata – 700001
4. Salutation
Use an appropriate formal salutation.
- Dear Sir,
- Dear Madam,
- Sir,
- Madam,
5. Subject
A subject line briefly explains the purpose of your letter. Keep it short and specific.
Example:
Subject: Request for Improvement of Road Safety Near Our School
6. Introduction
The first paragraph should clearly explain why you are writing the letter. Avoid unnecessary details and get directly to the purpose.
Example:
I am writing to draw your attention to the increasing traffic congestion and lack of proper pedestrian facilities near our school.
7. Main Body
The main body should provide relevant details about the issue. Explain the situation clearly and support your points with appropriate examples.
Divide longer letters into separate paragraphs. Each paragraph should focus on one main idea.
8. Conclusion
The final paragraph should summarize your request or explain the action you expect from the recipient.
Example:
I sincerely hope that you will look into this matter and take the necessary steps at the earliest.
9. Complimentary Close
Use a polite closing appropriate for a formal letter.
Examples:
- Yours faithfully,
- Yours sincerely,
10. Name and Signature

Sample ICSE Formal Letter
Question: Write a letter to the Municipal Commissioner complaining about poor road conditions in your locality.
24, Lake View Road
Kolkata – 700029
25th July 2026
The Municipal Commissioner
Kolkata Municipal Corporation
Kolkata – 700001
Dear Sir,
Subject: Complaint Regarding the Poor Condition of Roads in Our Locality
I am writing to draw your attention to the poor condition of the roads in our locality. Several roads have developed large potholes, making it difficult for pedestrians and vehicles to travel safely.
The problem becomes particularly serious during the monsoon season, when the potholes fill with water and become difficult to identify. This has already resulted in several minor accidents and has caused considerable inconvenience to local residents.
I kindly request you to arrange for the immediate repair of the damaged roads and ensure proper maintenance in the future. This would greatly improve the safety and convenience of everyone living in the area.
I sincerely hope that you will look into this matter and take the necessary action at the earliest.
Yours faithfully,
A Concerned Resident
