Your letter's polite. It reads respectfully. You've hit 180 words, stayed within time, and covered everything the prompt asked for. So why'd your examiner hand you a Band 5 instead of Band 7?
Here's what most students miss: tone isn't something you either nail or don't. It's a measurable skill you can practice and control. The gap between Band 5 and Band 7 usually comes down to how well you match your register to the situation, how naturally you sound (not stiff), and whether your politeness feels genuine or forced. Most people struggle with this because they treat tone as decoration, not as something examiners actually score.
Let's be straight about this. The IELTS band descriptors for Writing Task 1 specifically mark "appropriacy of register" and "effectiveness of tone." Examiners don't ignore this. It directly impacts your score. In this guide, I'll show you exactly what separates Band 5 from Band 7 tone, with real sentence examples you can use right now. You'll also learn how a free IELTS writing checker can help you spot tone problems before submission.
Tone is how you sound when you write. It's the personality in your words. In IELTS Task 1 letters, your tone has to fit the situation. A complaint should sound firm, not hostile. A request to a friend should feel natural but clear. An application letter needs to sound respectful without sounding like a robot.
The examiner isn't judging whether you're a good person. They're checking if you picked the right register, used language structures that fit the context, and balanced formality with warmth properly. The band descriptors explicitly say "register is appropriate to the task" for Band 7-8, but "register may shift awkwardly" for Band 5-6. That's a concrete, measurable difference.
Tip: Your tone needs to stay consistent from start to finish. When you jump between formal and casual language, readers get confused and you lose points on register. One tone per letter.
The first sentence sets your tone immediately. Examiners pick up on whether you sound confident, unsure, or defensive right away. Here's how three different openings land:
The scenario: You're asking a university for a refund because you didn't finish a course.
Band 5: "I am writing this letter to you because I am unhappy with the course that I took and I want my money back."
What's broken here? The tone sounds angry and demanding, not like someone making a reasonable request. All those "I" statements make it feel self-centered. "I want my money back" sounds aggressive, not respectful.
Band 7: "I am writing to request a refund for Course XYZ, which I enrolled in last month but was unable to complete due to unexpected personal circumstances."
This works because it uses proper formal structure ("I am writing to request"). It's specific: course name, timeframe. It explains the situation without sounding emotional. The tone is professional and reasonable. You sound like someone the university should actually listen to.
Band 5 students often swing too hard the other way. They get so scared of sounding rude that they sound fake or powerless. That kills your tone because it doesn't match reality.
The scenario: You're telling a landlord the heater in your apartment is broken.
Band 5: "I am extremely sorry to bother you with such a trivial matter, but if it is not too much trouble, I would humbly request that you might perhaps consider fixing the heating system in my apartment, if you possibly can, at your earliest convenience, if that is acceptable to you."
This is painful. You're apologizing for something that's literally the landlord's legal responsibility. You sound afraid of your own rights. That phrase "if it is not too much trouble" for a broken heater makes you sound helpless. This actually works against you in IELTS letter tone evaluation.
Band 7: "I am writing to inform you that the heating system in my apartment has stopped working. As this is a maintenance issue that requires urgent attention, I would appreciate if you could arrange a repair as soon as possible."
This is direct without being rude. You state the problem clearly. You explain why it matters (urgent). You make a reasonable ask. You sound like someone who understands their rights but respects the process. The tone matches the seriousness.
Band 7 writers use specific language choices that signal the right level of formality. These aren't fancy words. They're structural choices that work.
Tip: Skip contractions in formal letters. Don't write "can't", "won't", or "I'm". Write out "cannot", "will not", "I am" in formal requests, complaints, and applications. Contractions belong in casual letters to friends.
Most Band 5 letters nail the opening tone, then fall apart in the body. Students slip into casual language, throw in "I think" or "in my opinion" when they should state facts, or suddenly get vague after being specific at the start.
The scenario: A formal complaint to a restaurant about a bad experience.
Band 5: "Opening: Dear Manager, I am writing to complain about my experience at your restaurant on 10 May. Body: The food was really bad and the service was quite slow. I think your staff could have been nicer. Also the waiter guy forgot to bring my drink."
Watch what happened. The opening sounds formal. Then "really bad" is conversational. "I think" is too personal for a formal complaint. "waiter guy" is slang. "quite slow" is vague opinion. The whole tone collapsed midway through.
Band 7: "Opening: Dear Manager, I am writing to lodge a formal complaint regarding my dining experience on 10 May. Body: The main course was served cold, which is unacceptable for a restaurant of your standard. The service was notably slow. My drink order took over 20 minutes to arrive despite the restaurant being relatively quiet."
The tone stays formal throughout. "Lodge a formal complaint" matches the opening. Specific details replace vague complaints. Objective statements ("served cold", "took 20 minutes") replace personal opinions. The reader trusts this person because it sounds credible.
Your closing is the last thing the examiner reads. It's where your tone either lands or crashes. Band 5 closings often sound awkward, too hopeful, or confused about what comes next.
Band 5: "Anyway, I hope you will help me. Thank you so much. Sincerely Yours."
Problems everywhere. "Anyway" is filler. "I hope you will help me" sounds passive and desperate. "Sincerely Yours" is outdated. This closing makes you sound uncertain about whether you'll get what you asked for.
Band 7: "I look forward to your prompt response and thank you for your attention to this matter. Yours sincerely, [Your name]"
This closes with confidence, not rudeness. "Look forward to" shows you expect a response. "Prompt response" signals you want action within a reasonable time. "Attention to this matter" respects their time. "Yours sincerely" is the correct formal sign-off. The tone ends professionally.
Band 7 doesn't mean you're rude or demanding. It means you're polite but clear, respectful but confident. Most students mess this up because they think politeness means apologizing constantly, hedging everything, or sounding uncertain.
Here's the actual shift between Band 5 and Band 7:
Band 7 versions sound more confident because they assume you have the right to make the request. You're not begging. You're communicating like a professional. This confidence is what examiners look for when scoring IELTS task 1 tone evaluation.
Tip: In formal letters, avoid apologizing for making requests unless you actually did something wrong. Replace "Sorry to bother you" with "Thank you for your time" or skip it entirely.
You can train yourself to catch tone issues before an examiner sees them. Read your letter aloud. Listen for where you sound uncertain, overly apologetic, too casual, or robotic. Circle those spots. Then rewrite using the patterns you've learned.
Ask yourself these four questions:
These four checks take two minutes. They'll catch most tone problems before submission. Alternatively, paste your letter into an IELTS writing checker to get instant feedback on register and politeness against real band descriptors.
Let's look at two complete letters side by side to see how tone shapes the entire piece. Both cover the same situation: requesting a course refund.
Band 5 Letter:
Dear Sir or Madam,
I am writing because I took your Advanced Business English course last month and I am very unhappy with it. The course was not good for me. The lessons were boring and the teacher did not explain things very well. I paid £500 and I think I deserve my money back because it was a waste of my time.
I hope you will understand my situation and give me a refund soon. I really need the money back because I have financial problems.
Thank you and I hope to hear from you very soon.
Yours sincerely,
John Smith
What's wrong: "very unhappy" is emotional. "Not good" is vague. "Boring" and "did not explain" are complaints without evidence. "I deserve my money back" sounds demanding. "I have financial problems" is too personal. The tone shifts from formal to casual multiple times. This letter relies on vague language instead of specific facts.
Band 7 Letter:
Dear Sir or Madam,
I am writing to request a full refund for the Advanced Business English course (Course Code ABE-421), which I enrolled in on 1 April and completed only two weeks of the four-week program. I would like to request this refund due to a significant change in my personal circumstances that has made it impossible for me to continue.
Upon reflection, I found that the course structure did not align with my learning objectives. Specifically, the curriculum focused heavily on written communication, whereas I required training in spoken business English for my upcoming role. This mismatch became apparent after the first two sessions, and I made the difficult decision to withdraw.
I would appreciate your consideration of this request. Should you require any additional information or documentation to process the refund, please let me know and I will provide it promptly.
Thank you for your time and attention to this matter.
Yours sincerely,
John Smith
Why this works: Specific course code and date. Clear reason for the request (circumstance change). Specific details about the mismatch (written vs. spoken focus). No unnecessary apologies. Professional structure throughout. Tone stays formal and calm. The reader takes this person seriously.
Complaint letters: Band 5 writers often sound angry or sarcastic ("I'm sure you'll understand why I'm furious"). Band 7 writers sound firm but factual ("This issue requires immediate resolution").
Request letters: Band 5 writers apologize too much ("I'm so sorry to ask, but would you possibly..."). Band 7 writers are direct ("I would appreciate if you could...").
Application letters: Band 5 writers oversell themselves ("I am the perfect candidate"). Band 7 writers state qualifications objectively ("My experience in project management includes three years in leadership roles").
Thank you letters: Band 5 writers are gushy ("Thank you SO much, you're absolutely amazing!"). Band 7 writers are warm but professional ("I am grateful for your assistance and would welcome the opportunity to discuss this further").
