IELTS Writing Task 1 Letter Format Checker: Your Band Score Guide

Here's the thing: most students lose 2-3 band points on Task 1 letters before they even write a single sentence of body content. Why? Because they either ignore letter format rules entirely or apply them inconsistently. You might have brilliant ideas and solid grammar, but if your salutation looks sloppy or your closing doesn't match your opening, examiners notice. They notice hard.

This guide shows you exactly what the IELTS General Training examiners are looking for in your formal letter structure, with a focus on the specific layouts that separate Band 6 writers from Band 8 writers. You'll see weak examples next to strong ones, and you'll learn the exact rules that an IELTS letter format checker evaluates.

What IELTS Examiners Actually Check in Your Letter Format

Let me be blunt: format isn't just decoration. The IELTS band descriptors for Writing Task 1 include "Task Response," which specifically measures whether you've written a letter at all, and whether it's the right type of letter. Format is part of that.

Examiners scan for five core elements in the first 10 seconds:

• Correct salutation (Dear Sir or Madam, Dear Mr. Smith, etc.)
• Clear paragraph breaks and structure
• Appropriate tone and register for the letter type
• Correct closing (Yours faithfully, Yours sincerely, etc.)
• A signature or name below the closing

If even one of these is missing or wrong, you're signaling to the examiner that you don't understand the genre. That costs you points in Task Response, a weighting area that's worth up to 40% of your score on this task.

How Do Salutation and Closing Need to Match?

This is where most students mess up. You need to match your salutation to how you sign off. It's not optional. If you don't know the person's name, use "Dear Sir or Madam" and close with "Yours faithfully." If you do know their name, use "Dear Mr./Ms./Dr. [Name]" and close with "Yours sincerely." This consistency matters because register control is part of your band score for lexical resource.

Watch what happens when students ignore this rule:

Why is this weak? Because "Best regards" is semi-formal. You've opened formally but closed casually. Examiners see inconsistency, and inconsistency equals lower marks.

Now you've matched the register. The opening and closing sit at the same formality level. This is what Band 7+ looks like.

The Anatomy of a Proper Letter: Step-by-Step Layout

You have about 20 minutes for Task 1. Spending 30 seconds on letter format is worth it because it sets you up for success.

Here's the exact structure you need:

1. Your address (optional but common): Top left. Single line or stacked. Example: "42 Oak Street, Manchester, UK" or "42 Oak Street / Manchester / UK"
2. The date: One line below your address, left-aligned. Format: "22 August 2026" or "August 22, 2026" (both are acceptable).
3. Recipient's address (formal letters only): One line below the date. Left-aligned. Example: "The Manager / City Hospital / London"
4. Salutation: One line below, left-aligned. "Dear Sir or Madam," or "Dear Mr. Jones,"
5. Body paragraphs: Indent the first line of each paragraph or leave a blank line between them. Pick one method and stick with it.
6. Closing: One line below the last body paragraph. "Yours faithfully," or "Yours sincerely,"
7. Your signature or name: One line below the closing. If handwritten, write your signature above your typed name.

That's it. You don't need to overthink it. Just be consistent.

Three Letter Types You'll See: Format Differences You Must Know

Task 1 gives you one of three letter types. Each has a slightly different feel, and examiners know when you've misread the prompt.

Type 1: Complaint or Request Letter

You're writing to a company, local government office, or organization you don't know personally. Use "Dear Sir or Madam" and close "Yours faithfully." The tone is professional but can be slightly firmer. Example prompt: "Write a letter to the manager of a hotel where you had a bad experience."

Type 2: Personal Request Letter

You're writing to someone you know (a friend, family member, or acquaintance), but the topic is still reasonably formal. You might use "Dear [First Name]" and close with "Best wishes" or "Yours sincerely." Example prompt: "Write a letter to a friend asking them to help you with a project."

Type 3: Semi-Formal or Informational Letter

You're writing to someone you may or may not know, but the subject is friendly or informational rather than a complaint. Use "Dear [Name]" and close "Best wishes" or "Yours sincerely." Example prompt: "Write a letter to a prospective landlord introducing yourself."

Closing Phrases That Actually Work (And Which Ones Don't)

This is where students go wrong constantly. You have about five acceptable closings for IELTS Task 1. Use anything else, and you're signaling unfamiliarity with formal English.

Acceptable formal closings:

• Yours faithfully (when you've used "Dear Sir or Madam")
• Yours sincerely (when you've used a person's name)
• Best wishes (semi-formal, works when you know the person)
• Kind regards (semi-formal, safe choice)
• Yours truly (less common, but acceptable)

Closings that cost you marks:

Why do examiners care? Because register control is part of your Lexical Resource band descriptor. You need to show you can shift your tone based on context. Using "Cheers" in a formal complaint letter tells the examiner you can't.

Common Format Mistakes That Sink Band Scores

You don't have time to redo your entire letter during the exam. But you can avoid these traps from the start.

Mistake 1: Inconsistent Salutation and Closing

You write "Dear Sir or Madam" but close with "Yours sincerely." That's a mismatch. Examiners dock you for inconsistency. The rule is mechanical, not flexible: same register in and out.

Mistake 2: No Name Under the Closing

You sign off with "Yours sincerely," then leave a gap and write nothing. Incomplete. You must have your signature or your typed name below the closing phrase. Best practice: leave three blank lines, then type your name in full.

Mistake 3: Wrong Punctuation on Salutation and Closing

In British English (which IELTS uses), the correct format is "Dear Mr. Jones," with a comma. Some students write "Dear Mr. Jones:" with a colon. That's American style and will mark you as less familiar with British conventions. Similarly, "Yours sincerely," always has a comma after it, never a period.

Mistake 4: No Paragraph Breaks

You write the entire body as one block of text. This immediately signals you don't understand letter structure. Your examiner expects: opening paragraph (purpose of letter), middle paragraphs (details and explanation), closing paragraph (summary or next steps). Separate them visually. That's part of Coherence and Cohesion.

Mistake 5: Incorrect Date Format

Writing "22/08/2026" looks too abbreviated for a formal letter. Write it out: "22 August 2026" or "August 22, 2026." Both work. Abbreviated dates feel sloppy in formal correspondence.

How to Self-Check Your Letter Format in 60 Seconds

Before you move on to your next task or finish your exam, run through this checklist. It takes one minute and catches most mistakes.

• Salutation and closing match: "Dear Sir or Madam" + "Yours faithfully"? Or "Dear [Name]" + "Yours sincerely"? Check.
• Your name is below the closing: Is there a name or signature line after "Yours sincerely,"? Check.
• Commas are in the right places: "Dear Mr. Jones," and "Yours sincerely," both have commas, not colons or periods? Check.
• You have a clear date: Is it written out (e.g., "22 August 2026"), not abbreviated? Check.
• Paragraph breaks are visible: Can you count at least two or three body paragraphs, separate from each other? Check.

If you check all five, you've protected yourself from the most common format errors. You're not guaranteed a higher band, but you're no longer handing the examiner easy reasons to dock points.

Real IELTS Task 1 Letter Example with Format Annotated

Let's look at how this works in context. Here's a sample prompt and a properly formatted response:

Prompt: "You lost a valuable item on a bus. Write a letter to the bus company asking them to help you locate it. You do not know the person you are writing to."

Notice what's working here: the salutation and closing match ("Sir or Madam" plus "Yours faithfully"), there's a clear date, the body has three separate paragraphs with distinct purposes (opening, details, closing), and the name appears below the closing. This is Band 7-8 format.

Now compare it to what weak format looks like:

What's broken here? No salutation. No closing. No name below (it's just signed "James"). No paragraph breaks. The date is abbreviated. The tone is casual. This would score Band 4 or lower on Task Response alone because it doesn't even look like a letter. The format failure cascades into other scoring areas.
