Your letter reads like a text to your mate. You just lost three band points.
This is where most students slip up. They know Task 1 formal letters need a polite tone, but they don't actually understand what "polite" means in IELTS terms. They throw in casual phrases, use contractions in random spots, or sound so stiff that the examiner wonders if they copy-pasted from a template. The IELTS band descriptors for Writing Task 1 reward register that stays consistently formal, fits the context, and reads naturally. That's the sweet spot. Not robotic. Not too chummy. Not wishy-washy.
Here's what actually happens: tone mistakes hurt you in two places. Task Response asks whether you sound right for the situation. Grammatical Range & Accuracy checks whether you're using the correct language for that register. A Band 7 letter won't be flawless, but it'll be polished, respectful, and spot-on for the context. You're going to learn exactly how to build that.
The examiner isn't judging your personality. They're checking whether you can shift your language to match a specific situation. Can you sound formal when the moment calls for it? Can you ask for something without coming across as rude? That skill is worth real points.
Task 1 letters usually ask you to complain about something, request information, or apply for a position. Each one needs a different tone. Complaints should be firm but apologetic. Requests should be polite yet direct. Applications need confidence mixed with humility. Miss the tone, and the whole letter feels off. Band 5 writers sound uncertain or casual. Band 6 writers mostly get it right but slip up here and there. Band 7 writers control their tone consistently from start to finish.
Quick tip: Tone isn't just about word choice. It's sentence structure, how certain you sound, and how direct you are. A Band 7 letter uses all three together.
Let me be straight with you. Most Band 5 letters have one of these three mistakes, and they repeat it throughout.
Contractions (don't, can't, I'm, it's) are informal. Formal letters don't use them. Some students overthink this and use them in weird places or drop them randomly. That inconsistency screams Band 5.
Weak: "I'm writing to you because I can't use the gym equipment properly. It's broken, and I don't think that's acceptable."
Strong: "I am writing to lodge a complaint regarding the faulty gym equipment. I cannot use the machines safely, and I do not believe this situation is acceptable."
The difference? The weak version mixes casual and formal, creating confusion. The strong version commits to one register and sticks with it.
Students often mistake "polite" for "emotional". They'll write something like: "I'm so frustrated. This is absolutely terrible. I really think you need to fix this right now." That's Band 4 territory. Formal doesn't mean robotic, but it does mean restrained.
Weak: "I have to tell you that your service is absolutely awful. I'm extremely disappointed, and honestly, I deserve much better than this."
Strong: "Unfortunately, the service I received did not meet the standard I expected. I would appreciate your urgent attention to this matter."
The strong version conveys frustration without exclamation marks or over-the-top language. It's more convincing because it sounds professional and measured.
Some students write: "I am sorry to bother you, but I was wondering if maybe you could possibly help me?" That screams insecurity. A Band 7 letter is polite but confident. You have a right to make the request.
Weak: "I am sorry to disturb you, but would you mind perhaps considering my request?"
Strong: "I am writing to request information about your accommodation options for the summer term."
The strong version is direct, polite, and assured. No unnecessary apologies. No hedging language.
You don't need fancy vocabulary to sound formal. You need the right words, used consistently throughout. Here's what Band 7 actually looks like.
Quick tip: Formal doesn't mean stuffed. You're aiming for professional email tone, not Victorian-era prose. Write "I am writing" not "Permit me to humbly endeavor to articulate my profound sentiments."
Let's look at an actual scenario. This is typical Task 1 material.
The prompt: "You rented a car last month. When you returned it, you were charged extra for damage to the bodywork. However, you believe the damage was already there when you rented it. Write a letter to the car rental company explaining the situation and asking for a refund."
Here's how a Band 7 response handles tone (excerpt):
Band 7 Example:
Dear Sir or Madam,
I am writing to dispute the additional charge of £250 that was applied to my rental account following the return of vehicle registration number XY08 ABC on 15th March 2026.
Upon inspection of the vehicle at pickup, I noted several minor scratches to the front bumper, which were already documented on the rental agreement. When I returned the car, the same damage was present. Nevertheless, I was charged £250 for "bodywork repairs" upon my return. I believe this charge is unjustified, as the damage predates my rental period.
I would appreciate your urgent review of the rental record and photographic evidence from the initial inspection. Should this confirm my account, I would request an immediate refund of the disputed charge.
I look forward to your prompt response.
Yours faithfully,
Why is this Band 7? It avoids contractions, orders the complaint logically, includes specific details (registration number, date, amount), makes the request clear, and keeps a respectful tone throughout. No exclamation marks. No casual language. No wishy-washy hedging.
Before you hit submit, work through this self-check process.
Quick tip: Read your letter aloud. If it sounds like you're texting a friend, make it more formal. If it sounds like a robot wrote it, dial back the stiffness. Band 7 sounds like a professional who's patient but direct.
These are the specific changes that bump a letter from Band 6 to Band 7 in task 1 letter politeness evaluation.
| Band 6 Phrasing | Band 7 Upgrade |
|---|---|
| I want to complain about... | I am writing to lodge a formal complaint regarding... |
| Can you give me a refund? | I would request a full refund of the amount paid. |
| This is really bad. | This situation falls significantly short of acceptable standards. |
| I hope you can help. | I would appreciate your prompt attention to this matter. |
| Please tell me ASAP. | I would be grateful for your response at your earliest convenience. |
A Band 7 formal letter maintains consistent politeness while staying direct and clear. You never slip into casual speech, and your requests sound confident without being demanding. The tone feels professional—like you're writing to someone's business email, not texting a friend.
In practice, this means using "I would appreciate" instead of "can you please", avoiding every contraction without exception, and choosing measured language even when describing problems. Band 7 writers understand that formal vs informal register is about choosing the right register and holding it throughout the entire letter. A single contraction or casual phrase doesn't disqualify you, but consistent formality is what separates Band 7 from Band 6.
Before submitting, grab one paragraph from your letter and count these markers.
If your paragraph has anything from the first four categories and nothing from the fifth, your tone isn't ready for Band 7. Rewrite that section. Fix the contractions first, then swap out the casual words, then strengthen your request phrase.
Quick tip: You don't need to write in British or American English to sound formal. You just need to sound professional. Formal is formal across all varieties of English.
Here's something most guides skip: the IELTS formal letter tests whether you understand that making demands of strangers requires softening your language. Humans respond to politeness. Examiners know this. When you use an IELTS writing checker or evaluator, formal register consistency is one of the first things it measures.
This is why you use modal verbs strategically. Instead of "You must refund me" (demanding, rude), you write "I would request a refund" (polite, formal). Instead of "This is terrible" (emotional), you write "This does not meet expected standards" (professional, factual). You're not being fake. You're being smart about how you ask for what you need.
The examiner measures whether you can sustain this throughout the whole letter. Band 7 means you stay formal without slipping into casual speech. When you're working on your letter opening line, your closing paragraph, and every sentence between, you maintain the same register.
Tone consistency matters, and the best way to catch lapses is with real feedback. You can check your letter for formal tone and politeness using an IELTS writing checker to evaluate whether your register stays consistent throughout. You'll get specific notes on where contractions slip in, where informal words weaken your message, and exactly what Band 7 looks like for your letter type.
