Here's what examiners won't tell you: most Band 6 letters fail not because of grammar errors or spelling mistakes, but because they sound rude, abrupt, or inappropriately casual. You can have perfect punctuation and still lose marks because your tone feels off. This is where most students mess up.
The difference between a Band 6 and a Band 7 letter often comes down to one thing: politeness. Not excessive politeness. Not fake politeness. But intentional, strategic politeness that shows you understand your audience and can adapt your register. The IELTS band descriptors for Task Response at Band 7 specifically mention "appropriate register," and your tone carries that weight.
This guide walks you through exactly how to audit your own letters for tone, shows you the specific phrases that separate Band 6 from Band 7, and gives you a framework you can use right now on your next practice letter.
Task 1 letters aren't just about information. They're about communication. You're writing to a real person (in the scenario), and that person deserves respect. An examiner reads thousands of letters. A polite one stands out because it shows maturity and awareness.
Here's the thing: politeness isn't just morally right. It's scored. The IELTS Writing band descriptors include "appropriate register" as part of the Grammatical Range and Accuracy criterion. Register means the formality level and tone you use. Get it wrong, and you lose points. Get it right, and you unlock marks even with slightly weaker grammar elsewhere.
Band 6 writers often focus on completing the task: "I need to complain. Let me complain." Band 7 writers focus on how they complete the task: "I need to complain respectfully while keeping the door open for a solution."
Let's look at actual sentences and see where the politeness gap lives.
Scenario: You're writing to a hotel about a booking problem.
Band 6 (too blunt): "I made a booking with your hotel and you messed it up. This is unacceptable. I want my money back immediately."
Band 7 (appropriately direct): "I am writing to bring a matter to your attention regarding my recent booking. Unfortunately, there appears to be a discrepancy that I would appreciate your help in resolving."
Same message. Different tone. The Band 7 version uses "unfortunately," "appears to be," and "would appreciate" to soften the criticism while remaining clear about the problem. It shows you're human, not angry.
Scenario: You're requesting information from a course provider.
Band 6 (too casual/demanding): "Send me information about your courses ASAP. I need to know costs and dates."
Band 7 (polite and clear): "I would be grateful if you could provide me with information regarding your course offerings, including fees and upcoming start dates."
The Band 7 version uses conditional language ("would be grateful if you could") instead of commands. It's more formal without being stuffy. Notice "upcoming" is also more precise than "dates."
Scenario: You're making a complaint to a local council.
Band 6 (too emotional): "The noise from the construction site next door is driving me crazy! You need to do something about this now!"
Band 7 (respectful but firm): "I am writing to lodge a complaint regarding the noise levels from the construction site adjacent to my residence. The disruption is affecting my quality of life, and I would appreciate your attention to this matter."
See the difference? The Band 7 version replaces emotion words ("driving me crazy") with factual ones ("affecting my quality of life"). It uses institutional language ("lodge a complaint") that fits the register. The examiners see someone in control of their tone, not just their anger.
You don't need 100 new phrases. You need about 15, and you need to know when to use them. Here they are, organized by function.
For opening politely:
For softening requests or complaints:
For acknowledging the other person's position:
For closing professionally:
Tip: Don't memorize these phrases and robotically insert them. The key is using them where they fit naturally. A Band 7 letter sounds human, not like a template. Read it aloud. Does it sound like something you would actually say in a formal context? If not, rewrite it.
After you draft a letter, run through this checklist. Each "no" is a point where politeness might be slipping.
If you answered "no" to questions 1, 2, or 5, your tone is drifting toward Band 6 territory. Rewrite those sections.
Mistake 1: Using all caps or exclamation marks for emphasis. "I NEED THIS RESOLVED IMMEDIATELY!" sounds like you are shouting. Examiners notice. Instead: "I would appreciate your prompt attention to this matter." Calm, clear, professional. Same urgency, better register.
Mistake 2: Sounding accusatory when you should sound confused. Band 6 writers often blame: "Your company failed to send my package." Band 7 writers report: "I notice my package has not yet arrived as expected." The second version invites a solution. The first invites a defensive response.
Mistake 3: Switching registers mid-letter. You open formally ("I am writing to request") but then get casual ("I really need this" or "anyway, can you also..."). Examiners see inconsistency. They mark it down under "Grammatical Range and Accuracy" because register is part of that criterion. Stay formal throughout. This consistency matters more than you would think.
Mistake 4: Forgetting to buffer criticism with courtesy words. "This is poor service" hits harder than "I was disappointed by the level of service." Both say the same thing. One sounds professional; the other sounds rude. Band 7 writers know this distinction.
Mistake 5: Writing run-on sentences that feel angry or breathless. "I am furious because I paid for this service and you did not deliver and now I have no solution and I do not know what to do." That is emotionally honest but tonally wrong for a formal letter. Break it into smaller, controlled sentences: "I paid for this service in good faith. Unfortunately, I have not received what was promised. I am now in a difficult situation and would value your guidance on how to resolve this."
Complaint Letters: Your job is to be firm without being hostile. Open by explaining the situation objectively. Use "unfortunately," "regrettably," or "I was disappointed to find" before describing the problem. Close with what you want to happen, not threats. "I trust you will resolve this promptly" is Band 7. "Fix this or I will sue" is Band 3.
Request/Inquiry Letters: Politeness here means acknowledging the inconvenience to them. "I recognize you may be busy, but I would be grateful if..." shows you are not just thinking of yourself. The examiner notes this as "appropriate register." It costs you almost nothing and gains you points.
Application/Apology Letters: Use "I recognize," "I understand," and "I sincerely apologize." These phrases show accountability without groveling. Band 7 is not about being submissive. It is about being honest and respectful. "I was wrong because [reason]" is better than "I am so sorry, so sorry, so sorry."
Suggestion/Recommendation Letters: Frame your ideas as possibilities, not facts. "You might consider," "It could be beneficial to," or "I would suggest that" are all Band 7 friendly. "You should" or "The answer is obviously" sounds arrogant and loses marks.
Tip: Write your first draft however you feel. Angry? Write angry. Desperate? Write desperate. Then edit it into Band 7 tone. This two-stage process is faster and more authentic than trying to write politely from the start.
Reading your letter aloud changes everything. Your ear catches tone problems your eyes miss. If you stumble, sound angry, or feel awkward saying it, the tone is probably off. Rewrite it until it flows like something you would genuinely say in a formal letter to a real person.
Second, compare your letter to sample Band 7 responses. You can find these on the official IELTS website or in Cambridge IELTS books 8 through 16. Don't copy them. Instead, underline every politeness phrase. Notice where it appears in the letter structure. Copy those patterns into your own letters, but use your own words.
Third, ask yourself one question before you send: "Would I be ashamed to read this letter in front of the person I am writing to?" If yes, your tone is wrong. Band 7 letters are letters you would be proud to send, even if they are asking for something or complaining about something.

Some students swing too far the other way. They become so polite that their meaning gets lost. "It is possible that perhaps there might have been an issue with the order, if it is not too much trouble to investigate" is overly indirect. The examiner cannot tell if you are complaining, apologizing, or just being wishy-washy.
Band 7 is polite AND clear. "I believe there may have been an issue with my order, and I would appreciate your help in investigating" says the same thing but with backbone. You are polite. You are not apologizing for existing.
The rule of thumb: use one softening phrase per request, not three. Use concrete language, not vague language. Say what happened, say why it is a problem, say what you want. Be respectful in how you say it, not in whether you say it.
The tone you use depends on your relationship to the reader. A letter to a university admissions office requires different politeness than a letter to a friend's parent asking about housing.
To government agencies or companies: Stay formal throughout. Use "I am writing to," "I would appreciate," and "I look forward to hearing from you." No casual language. No contractions. This is where most Band 7 politeness happens.
To people you have a relationship with (but still formal context): You can warm up slightly in the closing. "I hope to hear from you soon" instead of "I look forward to hearing from you" works if the relationship calls for it. But the body stays formal.
To friends or family (informal letters): You can use contractions and casual words, but Task 1 letters are rarely this informal. Even a letter to a friend stays semi-formal in IELTS context. The difference between formal and semi-formal for IELTS is subtle. You are still using complete sentences and polite language. You are just slightly less stiff.
If you are unsure whether a letter should be formal or semi-formal, assume formal. You will not lose points for being too polite. You will lose them for being too casual.
Before you submit, scan for these tone killers.
Phrases like "you better," "you have to," or "you must" make you sound demanding. Replace them with "I would appreciate if you could" or "I would be grateful if you would."
Exclamation marks more than once in the entire letter. One at the very end in an informal letter might work. Multiple exclamation marks throughout? Band 6.
Words like "annoyed," "furious," "disgusted," or "livid." Stick to "disappointed," "concerned," or "regrettably." These words communicate the same feeling but with professional distance.
Questions that sound rhetorical or sarcastic. "Seriously, how hard is it to get my order right?" is Band 5 energy. "I would appreciate an explanation for why my order was incorrect" is Band 7.
Repetition of the same complaint without adding new information. "This is terrible. It is just terrible. I cannot believe how terrible this is." Band 7 says it once, provides detail, and moves forward.
Long paragraphs (10+ sentences) in a short letter. Politeness requires clarity, and clarity requires structure. Break your thoughts into shorter, tighter paragraphs.
