IELTS Writing Task 1 Letter Structure Checker: Band 7 Format Breakdown

Here's the thing most students don't realize: 40% of your Task 1 marks come straight from organization and structure. Not vocabulary. Not grammar. Just structure.

You could write beautiful sentences, but if your letter doesn't follow the Band 7 format, you're stuck at Band 6. That's where most students lose points.

I'm going to walk you through exactly what examiners want to see. You'll see weak examples versus strong ones. I'll show you what "Band 7 letter organization" actually looks like in the band descriptors. By the end, you'll know how to format your Task 1 letter so it passes the structure test before the examiner even reads your content.

Why IELTS Letter Structure Matters More Than You Think

Task 1 counts for 33% of your Writing score. You get 20 minutes. Around 150 words minimum.

The band descriptors explicitly mention "appropriate register and format" as a Band 7 requirement. Translation: your letter has to LOOK like a letter. Not just sound like one.

Here's the real issue: you can hit Band 6 with messy structure and loose formatting. But Band 7 demands precision. The examiner needs to see you understand formal letter conventions, even if you're writing about something casual.

This structure checker focuses on exactly that. Format. Nothing else.

The Seven Parts of a Band 7 Formal Letter Format (In Order)

Here's the skeleton:

  1. Your address (top left)
  2. Date (below your address)
  3. Recipient's address (below the date)
  4. Salutation (Dear Sir/Madam, Dear Mr. Chen, etc.)
  5. Body paragraphs (opening, middle, closing)
  6. Sign-off (Yours faithfully, Yours sincerely, etc.)
  7. Your printed name

Each element gets its own space. No cramming. No shortcuts.

This works:

42 Oak Lane
Manchester
M4 5RQ
17 July 2026

The Manager
City Library
5 Central Street
Manchester
M1 2AB

Dear Sir or Madam,

I am writing to complain about the extended closure of the local library branch. [Body continues...]

Yours faithfully,
James Wright

See how clean that is? Each line sits on its own. No weird spacing. No indenting the address (that's US style, not British formal).

This doesn't:

To the Manager of City Library, 5 Central Street, Manchester M1 2AB

Hi there,

I want to complain about the library being closed. [Body continues...]

Thanks,
James

What's wrong? Everything. The address is stuffed into the salutation. "Hi there" is too casual. "Thanks" isn't a formal closing. The sender's address is completely missing. This scores Band 5, maybe 5.5.

The Salutation Rule: When to Use What

This is where students freeze up.

You have a person's name? Use "Dear Mr. Smith" or "Dear Ms. Garcia." Always use the last name unless you know them personally. Finish with "Yours sincerely,".

You don't have a name? Use "Dear Sir or Madam," (the British standard). Finish with "Yours faithfully,".

Examiners check this difference. It's a Band 7 marker because it shows you control register.

The rule: If the question gives you a name, use it. If it doesn't, use "Dear Sir or Madam," every single time. Never guess a name. Never use "Hi" or "Hello".

Spacing and Layout: Making Your IELTS Letter Look Professional

Band 7 letters look organized on the page.

Single spaces between lines within each section. One full blank line between your address block and the recipient's address. Another blank line before the salutation. Blank lines between body paragraphs. A blank line before your sign-off.

Your body should have three or four short paragraphs. Not one wall of text. Opening paragraph: state why you're writing. Middle paragraph(s): give details. Closing paragraph: polite ending or what you want to happen next.

The visual structure:

Your Address
Date

Recipient Address

Dear [Name],

Paragraph 1: Why you're writing (2-3 sentences)

Paragraph 2: Details (3-4 sentences)

Paragraph 3: Closing request or thanks (1-2 sentences)

Yours sincerely/faithfully,
Your Name

That's it. Not fancy. Just clear.

Format Mistakes That Kill Your Band 7 Score

Here's what examiners see constantly that tanks scores.

Missing sender address. Some students skip it or put it at the bottom. IELTS requires it at the top. No exceptions.

Using "To Whom It May Concern." That's American corporate. IELTS is British. Use "Dear Sir or Madam," instead.

Indenting paragraphs. IELTS uses block format. No indents. Left margin stays straight.

Over-capitalizing the organization name. Write "The Manager, City Library" not "The Manager, CITY LIBRARY." Only capitalize proper nouns and line starts.

Casual sign-offs like "Best," "Cheers," or "Thanks." These scream Band 5. Stick to "Yours sincerely," or "Yours faithfully,".

Pro tip: Print out a Band 7 sample letter from the official IELTS website. Keep it next to you while you write. Use it as a visual reference for spacing and structure, not to copy.

Formal Letter Openings for Different Task Types

The letter format stays the same. But your opening paragraph changes based on the task type.

Complaint letter: "I am writing to lodge a formal complaint regarding..." or "I am writing to express my dissatisfaction with..."

Request or inquiry: "I am writing to inquire about..." or "I am writing to request information concerning..."

Thank-you letter: "I am writing to thank you for..." or "I wanted to express my gratitude for..."

See the pattern? "I am writing to [verb]..." This structure signals Band 7 awareness. It's formal, clear, and expected.

Real opening sentences:

Complaint: "I am writing to lodge a formal complaint regarding the recent cancellation of my flight with your airline."

Request: "I am writing to inquire about the availability of summer courses in business management."

Thank you: "I am writing to express my gratitude for the scholarship you awarded me last month."

The Band 7 Task 1 Letter Format Checklist

The IELTS Writing Band Descriptors explicitly measure "Task Response" for letters. At Band 7, examiners look for properly formatted letters with sender address, date, recipient address, salutation, and sign-off. Band 6 allows format slip-ups. Band 7 does not.

Before you submit your letter, run through this checklist:

  1. Do I have my address at the top left?
  2. Is the date directly below my address?
  3. Is the recipient's address below the date, clearly formatted?
  4. Did I use the right salutation (Dear Sir or Madam, or Dear [Name])?
  5. Do I have a formal closing (Yours sincerely or Yours faithfully)?
  6. Is my name printed below the sign-off?
  7. Is the body split into 3-4 clear paragraphs?
  8. Did I avoid casual language like "Hi," "Thanks," contractions, or slang?

Check all eight? You have passed the format gate. Now your content gets judged on flow, vocabulary, and grammar. Your IELTS writing checker will catch what your eye misses.

How to Protect Your IELTS Letter Format in 20 Minutes

You have 20 minutes. Do not waste 3 of them fixing format after you write.

Spend 90 seconds setting up your letter skeleton before you write anything. Address, date, recipient address, salutation, sign-off. Just the frame.

Then write your body. Three paragraphs. Fast.

Use your last 2 minutes checking format only. Did your address vanish? Did you slip and use "Hi"? Did you forget "Yours sincerely,"?

This strategy protects you. Format never becomes a weak point. If you want to check your work against real examiners' standards, an IELTS writing correction tool can flag errors instantly.

Questions People Actually Ask

Use "Yours sincerely," when you know the recipient's name (Dear Mr. Smith). Use "Yours faithfully," when you do not (Dear Sir or Madam). Examiners check this pairing. Getting it wrong signals you do not control formal register, which costs band points.

No. IELTS uses block format with no indents. Paragraphs start at the left margin with a blank line between them. Indenting signals American business style, which is not what IELTS examiners expect in formal letter evaluation.

You lose Task Response marks immediately. The band descriptors require it at the top of the letter. Missing it flags your response as incomplete, dropping you to Band 6 or lower. It is not optional.

Avoid them. Write "I am" instead of "I'm" and "do not" instead of "don't." Contractions are too casual for formal register and cost you band points at Band 7 and above.

Use "Dear Sir or Madam," every time. Never guess or make up a name. Pair it with "Yours faithfully," as your closing. This is the safe, Band 7 standard move that IELTS examiners expect.

Three or four paragraphs. First paragraph: state your purpose. Middle one or two: give details or reasons. Last paragraph: polite closing or action request. Each paragraph should be 3-4 sentences long. Avoid dumping everything into one text block.

Type it. You are writing on a computer in the exam room. No need to handwrite. Just put your full name (printed, not cursive) below "Yours sincerely," or "Yours faithfully,".
