Here's what most students don't realize: examiners notice your letter closing before they finish reading your opening. The last words you write stick in their mind. Mess up the sign-off, and you've just handed them a reason to mark you down on Coherence and Cohesion, even if the rest of your letter is solid.
This guide shows you exactly which closing phrases work for IELTS Task 1, which ones don't, and how to catch your mistakes before you submit. Use this as your personal IELTS writing checker for one of the most overlooked elements of formal letter writing.
The IELTS band descriptors for Writing Task 1 mark you on four things: Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Your closing phrase touches at least two of these.
A Band 7 writer uses closing phrases that fit the context and are grammatically correct. A Band 5 writer either forgets to sign off properly or picks a phrase that doesn't match the formality level. The difference might seem small, but when you're aiming for 6.5 or 7, every point counts.
What examiners really want to see is that you understand register. They want proof that you know the difference between writing to your friend, your boss, and a company receptionist. Your closing phrase proves that instantly.
Formal letters dominate IELTS Task 1. You'll write to universities, councils, managers, and government offices. Here are the closings that work every single time.
Good: "Yours faithfully," — use when you don't know the recipient's name
Good: "Yours sincerely," — use when you know the recipient's name
Good: "Kind regards," — formal but slightly warmer, works in any situation
Good: "Best regards," — equally safe, works universally
These four phrases are bulletproof. They fit formal contexts. They're grammatically standard. They signal to the examiner that you know what you're doing. Any IELTS writing checker worth using will flag deviations from these as potential issues.
"Regards" on its own is acceptable but weaker. "Thank you" as a closing is casual and doesn't follow British convention. "Sincerely" without "Yours" is American and isn't standard IELTS format.
Weak: "Regards," — too casual, implies the letter is rushed
Weak: "Thank you," — confuses closing with courtesy. Examiners expect a proper sign-off
Some IELTS prompts ask you to write to a colleague or someone you have a relationship with, but it's still professional. That's where semi-formal closings shine.
Good: "Best wishes," — friendly without being unprofessional
Good: "Warm regards," — warmer than "kind regards" but still formal enough
Good: "All the best," — works when you know the person slightly
The rule: if you know the person by name and have written to them before, you can be warmer. But never slip into "Cheers" or "Talk soon." That's Band 5 territory.
This is where most students slip up. Not because they don't know the rules, but because they overthink it.
Wrong: "You're faithfully," — you're = you are. This is a grammar error on your closing line.
It's "Yours," not "You're." The examiner sees this and marks you down on Grammatical Range and Accuracy. It's a small slip with big consequences.
Wrong: "Yours very faithfully," — over-formal, sounds awkward
Wrong: "Kind and warm regards," — redundant, dilutes the phrase
Stick to one phrase. The examiner isn't scoring you on creativity here. They're scoring you on whether you can use the right phrase for the right situation.
Wrong: "Kind regards, mate," — contradicts itself. "Mate" kills the formality.
Your closing is the last thing the examiner reads. Don't sabotage yourself by switching register at the finish line.
Wrong: "Yours faithfully" (no comma)
The comma after the closing phrase is required in British English. It's a small detail, but it counts as part of Grammatical Range and Accuracy.
Your closing isn't just the phrase. It's the phrase, comma, then your name.
Here's what it looks like:
Correct:
Dear Sir or Madam,
[Body paragraphs]
Yours faithfully,
John Smith
That's it. Phrase. Comma. Name. If you've mentioned a role in the letter, you can add it below your name, but it's not required for IELTS Task 1.
Wrong:
Yours sincerely
John Smith
(Missing comma after the closing phrase)
Don't know the recipient's name? Use "Yours faithfully," or "Kind regards,". Know their name? Use "Yours sincerely," or "Best regards,". Writing to someone you have a relationship with? Use "Best wishes," or "Warm regards,". This simple decision prevents most sign off IELTS letter errors before they happen.
Quick tip: Unsure about formality? Go formal. You can't go wrong with "Yours faithfully," or "Kind regards," in any IELTS Task 1 scenario. Examiners expect formal or semi-formal. They'll never penalize you for choosing one of these.
Let's look at actual IELTS-style prompts and how to close them.
Prompt: Write a letter complaining about your recent stay at a hotel.
What you know: You don't know the hotel manager's name. Tone: Formal but direct.
Your closing: "Yours faithfully,"
Why: Standard for unknown recipient in formal complaint letters
Prompt: Write to your university requesting an extension on your application deadline.
What you know: You have the admissions officer's name from the website. Tone: Formal and polite.
Your closing: "Yours sincerely,"
Why: Standard when you know the recipient's name
Prompt: Write thanking your former employer for a job reference.
What you know: You know them and have a positive relationship. Tone: Warm but professional.
Your closing: "Best wishes," or "Warm regards,"
Why: Reflects gratitude and your existing relationship
When you're working on matching your tone and register to the prompt, your closing phrase is one of the easiest ways to signal that you understand the formality level.
Before you submit any IELTS letter, run through these four questions:
Yes to all four? Your closing is solid. No to any of them? Rewrite it now. Many students use an IELTS writing correction tool to catch these issues, but a quick manual review works just as well.
Pro tip: Many students change their closing at the last minute and introduce typos. Write it early and leave it alone. Trust that "Yours sincerely," or "Kind regards," will work. They always do.
