IELTS Writing Task 1 Letter Tone Checker: How to Hit Band 7 on Request Letters

Here's the problem hundreds of IELTS candidates face every year: your grammar's solid, you've hit the word count, and then the score comes back—Band 6. You're left wondering what went wrong. The answer? Your tone is off.

Tone matters way more than most students think in IELTS Writing Task 1 letters. The examiner isn't just checking whether you know how to spell "sincerely." They're looking at whether you actually understand the social context of the letter and whether you're communicating in a way that fits the situation. A request letter needs a completely different tone than a complaint. Writing to a university isn't the same as writing to a friend.

This post walks you through exactly how to evaluate your own letter tone, spot where it's falling short, and fix it before test day. By the end, you'll know what examiners are really looking for when they're deciding between Band 6 and Band 7. And if you want to check your letter in real time, our free IELTS writing checker gives you instant feedback on tone, register, and band score estimates.

What Band 7 Actually Means for Task 1 Letters

Let's start with the basics. According to the IELTS band descriptors, Band 7 requires you to address all parts of the task clearly. You also need to keep an appropriate register and tone all the way through the letter.

Here's the key word: appropriate. Your tone needs to match what the letter is for and who you're writing to. If you're making a formal request to your local council about a pothole, you can't sound like you're chatting with friends. If you're asking a friend about accommodation, you can't write like a lawyer.

Most Band 6 letters fail for one of three reasons: they're too casual when they should be formal, too stiff when semi-formal would work, or they jump around—starting formal and sliding into casual by paragraph three.

Three Tone Mistakes That Keep You at Band 6

Mistake 1: Sounding too informal in formal letters. You're writing to a company or institution, but you sound like you're texting a friend.

See the difference? The weak version uses "guys," "really annoyed," and "Cheers"—all signals of casual conversation, not formal business. The Band 7 version opens with "I am writing to," gives specific details, and uses phrases like "at your earliest convenience."

Mistake 2: Sounding overly formal in semi-formal letters. You're writing to someone you don't know personally, but not to an institution. You don't need to sound like you're arguing a case in court.

The weak version throws in "hereby," "aforementioned," and "forthcoming." That's not professional—it's artificial. A native speaker would cringe reading it. Band 7 tone feels natural and appropriately formal without the overdone language.

Mistake 3: Switching tone mid-letter. You start formal and drift into casual language. Examiners catch this instantly.

This letter starts formal, crashes into text-speak, then tries to recover. That inconsistency costs you marks because it signals you don't fully grasp how to maintain register in formal communication.

A Practical Method to Check Your Own Letter Tone

You don't need fancy software to spot tone problems. Try this approach:

1. Read your letter aloud. Does it sound natural, or does it feel robotic? Would you actually say these words to this person? Could your grandmother read it at a business meeting without anyone raising an eyebrow?
2. Count your contractions. Formal letters use very few (don't, can't, it's). You might use one or two, but not five. If you've got zero in a semi-formal note to a potential landlord, you're probably too formal.
3. Mark words that feel "off." Circle any word that feels too casual (cool, awesome, guys) or too stiff (aforementioned, whereby, forthwith). If you'd never use it talking to the actual person, don't use it in the letter.
4. Check your first and last lines. These set the tone for everything. If your opening is casual but your closing is stiff, you've got a register problem.
5. Read a Band 7 sample in the same category. Compare it to yours. Does your tone feel similarly formal? If the sample sounds more natural and professional, that's your gap.

Request Letters: The Tone That Gets Band 7

Request letters are tricky because your tone has to balance respect with clarity. You're asking for something, so you need to be polite. But you also need to be direct about what you want.

Weak request tone: "I was wondering if maybe you might possibly consider thinking about whether you could potentially provide me with information regarding accommodation options, if that wouldn't be too much trouble."

This is over-apologetic and vague. What type of accommodation? When do you need it? You're begging instead of asking.

Band 7 request tone: "I am writing to enquire about accommodation availability for the summer semester. Could you please provide information about single rooms and the associated costs?"

This is polite but confident. You use the formal opener "I am writing to," you're specific about what you need, and "Could you please" is respectful without groveling. This is Band 7 tone for a formal letter.

Formal vs. Semi-Formal: The Real Difference

Most Band 6 candidates mix these two up. Here's what separates them.

Formal letters go to institutions, companies, government bodies, or people in authority you don't know. Think council, university admissions, company HR.

• Opening: "Dear Sir or Madam," or "Dear [Name],"
• Almost no contractions
• Passive structures work fine: "It has been brought to my attention..."
• Direct, clear language without over-apologizing
• Closing: "Yours faithfully," or "Yours sincerely,"

Semi-formal letters go to people you know professionally or have a light personal connection with. Think a teacher you know, a potential landlord, a colleague.

• Opening: "Dear [Name],"
• One or two contractions are fine
• More personal tone, still respectful
• You can show personality without being casual
• Closing: "Yours sincerely," or "Best regards,"

IELTS usually makes the context clear in the prompt. If it says "write to the hotel manager," that's formal. If it says "write to a friend," that's casual. But request letters to people you don't know well often sit in that semi-formal zone, and that's where most students slip up. If you're unsure, lean slightly more formal—it's easier to dial back formality than to suddenly seem more professional once you've sounded too casual.

Real Example: A Band 7 Request Letter Broken Down

Scenario: You want information from a language school about their summer courses.

The letter:

Dear Sir or Madam,

I am writing to enquire about the summer English courses offered by your language school. I am particularly interested in intensive courses for intermediate learners.

Could you please provide me with information about the following: course dates, class sizes, teaching qualifications of instructors, and fees?

I would also appreciate if you could send details of accommodation options near the school, as I am relocating from overseas.

Thank you for your assistance. I look forward to hearing from you.

Yours sincerely,
[Name]

Why this gets Band 7 for tone:

• Opens with formal "Dear Sir or Madam" and closes with "Yours sincerely" (consistent throughout)
• Uses "I am writing to" (standard formal letter opening)
• Says exactly what information is needed (clear, organized list)
• Polite without apologizing ("Could you please" not "Would you possibly maybe...")
• No contractions, but language feels natural, not stiff
• Short paragraphs with one clear purpose each
• Professional closing that acknowledges the reader
