IELTS Writing Task 1 Letter Closing Mistakes Checker: Band 5 to 7

Your letter closing is often the last thing an examiner reads. Yet it's where most Band 5 and Band 6 writers throw away points without even realizing it.

The closing affects two major scoring areas: Task Response (did you end the letter appropriately?) and Grammatical Range & Accuracy (is your sign-off spelled correctly?). A weak closing can drag you from Band 7 down to Band 6. A strong one signals you're in control.

In this guide, you'll learn what examiners actually look for in your letter closing, which mistakes cost you marks, and exactly how to upgrade from a forgettable sign-off to Band 7 material.

Why Your IELTS Letter Closing Matters More Than You Think

IELTS examiners read hundreds of letters. They're checking three things in your closing: Does it fit the letter type? Is it grammatically clean? Is your final message clear?

Band 7 requires you to "write with appropriate register and tone" throughout the entire letter—and that includes those final lines. Band 5 and 6 closings often feel awkward or unclear. The reader pauses and thinks, "Wait, what exactly are they asking for here?"

Be honest with yourself: an examiner expects your closing to be flawless. It's only 15-30 words. A typo in your name or sign-off? That signals a Band 6 ceiling or lower. You simply don't have room for careless errors here.

The Classic Band 5-6 Closing Mistake: Trying Too Hard to Sound Formal

Band 5 and 6 writers often panic about formality and produce closings that sound stiff or even broken.

The grammar is fine, but "regarding this matter" is vague and disconnected from what the letter actually asked for. The writer also repeats language used earlier—a sign they're padding instead of wrapping up cleanly.

This closing is specific, polite, and short. No filler. No repetition. It signals the end without awkwardness.

Sign-Off Conventions: How to Get Your Letter Ending Right

A correct sign-off is the foundation of a Band 7 task 1 letter ending. Examiners check this carefully because it's a standard convention that separates polished writing from careless work.

Here are the standard sign-offs for IELTS General Training letters:

• Yours sincerely (use when you know the person's name)
• Yours faithfully (use when you don't know the person's name, like "Dear Sir or Madam")
• Kind regards (less formal, still Band 7)
• Best regards (slightly less formal than "Yours sincerely")

Common misspellings and errors in Band 5-6 letters that cost you marks:

• "Your sincerely" (missing the "s"—this one kills your score)
• "Sincerely yours" (wrong word order for British English)
• "Yours truly" (American English, not standard for IELTS)
• "Respectfully yours" (American, too formal)
• No comma after the sign-off: "Yours sincerely" (modern convention includes one)

The correct format is:

• Yours sincerely,
• [Your full name]

Leave one blank line between the sign-off and your name. This is standard IELTS letter formatting.

Match Your Closing to the Letter Type

Task Response includes appropriateness. Your closing must fit what you're writing.

Complaint letter: You're requesting a fix, not demanding one. A weak closing sounds frustrated or desperate.

The second version stays polite while still being firm. That's the Band 7 balance.

Request or application letter: You're asking for something. Express hope or thanks, not demands.

Inquiry or informational letter: Keep it warm but professional.

The Band 6 Trap: Generic or Incomplete Closings

Band 6 writers often rush the closing or make it so generic it could fit any letter.

Nothing's wrong here grammatically, but it's forgettable. "Consider my request" is vague—it doesn't remind the reader what you actually asked for.

This echoes the letter's purpose (resolving an issue) without copying earlier sentences word-for-word. It's specific and polished.

Grammar Mistakes That Keep You at Band 6

The entire closing paragraph counts for Grammatical Range & Accuracy. Here are the mistakes that trap writers below Band 7.

Mistake 1: Tense shifts

"Will have resolved" is future perfect. It's awkward here. Stick with simple future.

Mistake 2: Casual language in formal letters

Too casual. The all-caps is inappropriate. Band 5 energy.

Mistake 3: Sentence fragments

This is a fragment—no main verb. It reads like informal texting.

Build Your Band 7 Closing in Three Simple Steps

Step 1: Write your closing statement (2-3 sentences, max)

Reference the letter's main purpose without copy-pasting earlier paragraphs. Use synonyms instead.

Say your letter asks to change a booking date. Here's what not to do:

Weak: "I am asking to change my booking date." (Pure repetition.)

Strong: "I would be grateful if you could accommodate this change to my booking." (You've rephrased it, stayed polite, and stayed clear.)

Step 2: Pick the right sign-off

Know the person's name? Use "Yours sincerely". Don't? Use "Yours faithfully". Either choice gets Band 7. Don't overthink this part.

Step 3: Write your full name

Write your complete first and last name. Not "John" or "JS" or a nickname. Write "John Smith".

Real IELTS Letter Closing Examples

Example 1: Complaint about restaurant service

Letter opens: "Dear Manager, I am writing to lodge a complaint about my recent experience at your restaurant."

Strong closing: "I trust you will take this matter seriously and ensure your staff receive proper training. Yours sincerely, Rachel Foster"

Example 2: Request for accommodation extension

Letter opens: "Dear Sir or Madam, I am writing to request an extension to my current booking."

Strong closing: "I would be grateful if you could accommodate this request at your earliest convenience. Yours faithfully, Priya Kapoor"

Example 3: Inquiry about job opportunities

Letter opens: "Dear Mrs. Jensen, I am writing to express my interest in potential vacancies at your organisation."

Strong closing: "Thank you for considering my application. I would welcome the opportunity to discuss this further. Yours sincerely, Lucas Bauer"

Notice the pattern: each closing is 1-2 sentences, uses the correct sign-off, and echoes (without copying) the letter's main point. When you're working on your letter opening, keep this balance in mind for the whole letter.

Common Questions About IELTS Letter Closings
