Writing a formal letter

It also lists the habits that turn an average letter into a convincing one.

What a formal letter is

A formal letter is written to someone you do not know personally, such as an editor, a head teacher, a council officer or a company manager. It has a clear practical purpose. You might complain, request, persuade, apply or suggest a change.

In IGCSE English the task usually grows out of a reading passage. You read the situation, take a role and write back in the form the task asks for.

A formal letter needs politeness and pressure together. The reader has power over the result, so you must be courteous. But you also need something from them, so you must be firm.

Students who understand this write letters that sound like adults. Students who forget it sound either too shy or rude.

Tone, layout, greetings and endings

The tone is formal all the way through. Do not use contractions (such as “don’t”), slang or chatty comments. Write full, controlled sentences.

Formal does not mean stiff. The best formal writing is plain, direct and confident.

The layout follows a standard order: your address, the date, the reader’s address, the greeting, the body and the sign-off.

• Greeting: “Dear Sir or Madam” if you do not know the name. “Dear Mr Tan” or “Dear Ms Lim” if you do.
• Sign-off: “Yours faithfully” after “Sir or Madam”. “Yours sincerely” after a name.

Layout rules vary by board and by whether the task is a letter or an email. Check our qualification pages for the current requirements.

A worked opening, written by our teachers

This is our own original example, made for teaching.

Dear Ms Rahman,

I am writing as a regular user of the Sungai Buloh community library to ask you to reconsider the plan to reduce its opening days. The library is more than a room of books.

For many families in our area, it is the only quiet, warm place where children can study after school. It is also where older residents can read newspapers they cannot afford to buy.

I understand that the council must save money, and I accept that some choices are difficult. But I ask you to weigh the library’s value against the saving. One closed afternoon a week may look small on a budget sheet. Yet it removes the very hours that working parents depend on.

I would therefore be grateful if the council would keep the current opening days. I look forward to your reply.

Yours sincerely, Daniel Wong

The first sentence gives the purpose. The second paragraph shows understanding of the reader’s problem before it presses a specific point.

The last paragraph says exactly what the writer wants. A strong formal letter repeats this pattern.

Checklist for a strong response

• The purpose is clear in the first two sentences.
• The tone stays formal from start to finish.
• Paragraphs build the argument and do not repeat it.
• There is a specific, reasonable request, not only a complaint.
• The greeting and sign-off match.
• You acknowledge the reader’s point of view before you push back.
• The last paragraph says what you want next.

Common mistakes

The most common mistake is a tone that slips: the letter starts formally and ends like a text message. The second is vagueness, with lots of feeling and no request the reader can act on. The third is a greeting and sign-off that do not match.

A fourth is one huge paragraph that hides the argument. A fifth is forgetting the reader halfway and writing for yourself. Knowing these traps in advance is most of the cure.

How this helps your other writing

A formal letter uses skills from other tasks. You need close reading, because your role and purpose come from the passage. You need tone control, which you also use in reports, speeches and articles.

You need accurate punctuation for addresses, dates and sentences. Explore our skills guides and grammar guides, and see the format in our annotated model responses.

Students usually get stuck keeping the tone formal while still sounding firm. They either say “sorry to bother you” too often or sound angry.

In 1-to-1 lessons, our teachers rewrite two or three weak sentences with the student into a polite but direct version. This is part of our First Language English tuition, from RM70/hr.

Bring a recent letter to a paid one-hour trial lesson, and the teacher who would continue will mark it with you.

Next, visit our original practice tasks to write this form to a real brief. Our IGCSE English tuition page explains how lessons run. When you are ready, the paid one-hour trial is the first step.
