IELTS Writing Task 1 Letter Format Checker: Your Band 7 Blueprint

Here's what happens: students lose 2-3 band points on Task 1 letters not because their ideas are weak, but because the format looks careless. The examiners grade on Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. You can write brilliantly and still drop points if your letter structure doesn't follow the rules that professional correspondence follows.

This guide shows you exactly what Band 7 letter formatting looks like, where students go wrong, and how to catch mistakes before you hand it in. Whether you're using an IELTS writing checker or reviewing your work manually, the same principles apply.

Why Format Actually Costs You Band Points

Format isn't just decoration. It's part of your Task Response score. The official band descriptors don't say "use proper letter format," but they do assess whether you've completed the task appropriately. When an examiner sees a formal letter crammed into paragraph blocks instead of proper structure, they mark you down for not understanding the genre.

The difference between Band 6 and Band 7? Band 7 shows "appropriate register and format for the task." Band 6 essays sometimes get the tone right but mess up the formal conventions. That gap costs you points.

You have 20 minutes. You need to write at least 150 words. You can't afford to lose marks on something you control—layout and structure.

The Five-Part Letter Structure for Band 7

Every formal IELTS Task 1 letter (General Training) needs these five sections, in this order:

1. Your address (top left)
2. Date
3. Recipient's address
4. Greeting (salutation)
5. Body paragraphs
6. Closing

Let me show you what this looks like in practice.

See the spacing? Each section sits separately. No crowding. Addresses on their own lines. This is what the examiner expects to see.

What Is IELTS Task 1 Letter Format and Why Does It Matter?

IELTS Task 1 letter format refers to the structure and layout conventions expected in formal and semi-formal correspondence. It includes proper placement of your address, the recipient's address, the date, salutation, body paragraphs, and closing signature. Getting this right signals to the examiner that you understand professional English conventions, which directly affects your Task Response and Coherence scores.

Three Common Letter Format Mistakes (And How to Fix Them)

This is where most students slip up.

Mistake 1: The Wrong Greeting

You don't know the recipient's name? Use "Dear Sir or Madam," followed by a comma. You know their name? Use "Dear Mr. Smith," or "Dear Ms. Johnson," again with a comma, not a colon.

The slash in "Sir/Madam" reads like informal text speak. The colon instead of a comma looks wrong. "Hi there" is too casual for a formal letter.

Mistake 2: Missing the Closing Line

Your letter needs a closing phrase before your signature. If you opened with "Dear Sir or Madam," use "Yours faithfully,". If you used a name, use "Yours sincerely,". Then skip a line and write your name.

Miss this closing and you signal to the examiner that you don't know formal letter writing. It's a Band 6 flag.

Mistake 3: One Dense Block of Text

Some students write the entire letter as one paragraph. This kills Coherence & Cohesion immediately. Even if your ideas connect logically, it looks unstructured and feels hard to read.

The second version isn't longer. It's just clearer. Each paragraph has one job.

The Three-Paragraph Body: Your Winning Structure

Most Task 1 letters fit into three body paragraphs after your greeting. Here's how to build them.

Paragraph 1 (Introduction): State your purpose in one or two sentences. "I am writing to apply for the position of Marketing Assistant as advertised in last Sunday's newspaper." That's enough. Don't overexplain or add background that nobody asked for.

Paragraph 2 (Details/Body): Develop your main point. If you're complaining, explain what went wrong. If you're requesting something, give context and specifics. If you're applying, mention relevant experience. Aim for 4-6 sentences here. This is where your idea lives.

Paragraph 3 (Closing/Call to Action): Wrap up and say what you want next. "I would appreciate your prompt attention to this matter," or "I look forward to hearing from you at your earliest convenience." Then move to your closing line.

The 3-Minute Format Check Before You Finish

Before you submit, run through this checklist. It takes 90 seconds and catches most formal letter structure band 7 errors.

1. Is my address at the top left, then the date, then the recipient's address? Check.
2. Is my greeting "Dear Sir or Madam," or "Dear [Name]," with a comma?
3. Are my body paragraphs separated by line breaks? (Not one dense block.)
4. Do I have a closing line like "Yours sincerely," or "Yours faithfully," before my name?
5. Is my tone formal? (No "Hi!" or "Cheers" or contractions like "can't".)

That's your format audit. Takes 60 seconds. Saves two band points. If you want real-time feedback while writing, use an IELTS writing checker to catch these errors instantly.

Formal Register: The Language Matters as Much as the Layout

Format alone won't get you to Band 7. You also need formal register. That means no contractions in formal letters. Don't write "can't" or "won't" or "doesn't". Write out the full form: cannot, will not, does not.

Notice "unable" instead of "can't", and "Would it be possible" instead of "Would you mind". The whole tone shifts.

Avoid casual words: "loads of", "got", "nice", "pretty good". Replace them with: "considerable", "acquired", "pleasant", "quite favourable".

Real IELTS Example: Putting It All Together

Let's walk through a real IELTS prompt and show how format works in context.

Prompt: "You recently stayed in a hotel and had a poor experience. Write a letter to the hotel manager complaining about your stay and asking for a refund."

What's working here? Clear structure. Proper spacing. Formal tone throughout. Specific complaints. Direct request. This reads like an actual letter, not a student guessing at format. The examiner doesn't have to squint or re-read for clarity.

If you want to understand how to strengthen your complaint letters specifically, our guide on letter tone accuracy breaks down how to maintain formality while making your point.

Your Format Checklist: Memorize This

Print this or save it. Five seconds of letter writing correction review saves you from the Band 6 ceiling.

Before you submit your letter, check all of these:

• My address is in the top left corner, with line breaks between street, city, postcode, country.
• I've written the date in full (22 August 2026, not 22/8/26 or 22.08.26).
• The recipient's address is complete with name, title, organization, location, postcode.
• My greeting is "Dear Sir or Madam," or "Dear [Name]," with a comma, not a colon.
• Each paragraph is separated by a line break (no dense blocks of text).
• My closing line is "Yours sincerely," (for named recipients) or "Yours faithfully," (for unknown recipients).
• I've left a line break before typing my name.
• I've used zero contractions (can't, won't, doesn't, haven't).
• My tone is formal throughout; no casual expressions like "loads of" or "got".

That's nine checks. Do all nine. You're ready to submit.

Why This Matters for Your Overall Score

Letter format might seem like a small thing. It's not. Format errors signal carelessness. When an examiner sees proper structure, clear spacing, correct greetings and closings, they immediately categorize you as someone who understands English business conventions. That's the difference between Band 6 and Band 7.

The five-part structure we outlined above isn't complicated. It's just a system. Once you memorize it, you don't have to think about it during the exam. You spend your 20 minutes on what actually matters: clear ideas, formal tone, and specific details.

Beyond format, if you're working on Task 1 letters, understanding how to avoid tone and register mistakes is equally critical. Examiners mark down for tone shifts just as much as format errors.

Next Steps

Practice one letter today using this structure. Don't edit as you write. Just follow the five-part layout and the three-paragraph body. Get the shape right first. Then check it against the nine-point checklist above.

Format is your Band 7 shortcut. Master it. It costs almost nothing and pays off immediately.
