IELTS General Training Task 1: Informal Letters (Writing to Friends & Family)

In the IELTS General Training Writing Task 1, the Informal Letter is often a favorite among test-takers. After all, writing to a friend about a holiday or apologizing for missing a party feels much more natural than complaining to a corporate manager.

However, this comfort zone is exactly where many students lose points.

Examiners often penalize candidates who are too casual (using text-message slang) or who accidentally mix formal academic words into a friendly chat. To score a Band 7.0 or higher, you must demonstrate a perfect command of conversational English while strictly answering the prompt.

This guide breaks down the golden rules of the informal tone, the vocabulary you need, and the exact structure to write a flawless letter to a friend or family member in just 20 minutes.

How to Identify an Informal Letter Question

Identifying this task is the easiest step. The letter instructions will explicitly tell you who you are writing to.

You are writing an informal letter if the instructions say:

• Write a letter to a friend…
• Write a letter to your brother/sister…
• Write a letter to an English-speaking pen pal…

If the letter mentions a friend, you must use an informal tone. Treat the letter as a warm, conversational dialogue between two people who know each other very well.

The Golden Rules of the “Friendly” Tone

To prove to the examiner that you understand the informal register, you must break some of the rules of academic writing.

1. Use First Names Only: Never write Dear Mr. Smith or Dear Friend. Always use a standard first name: Dear Alex, or Dear Sarah,.
2. Use Contractions Everywhere: This is mandatory for a high score in an informal letter. You must write I’m, can’t, won’t, haven’t, I’ve, instead of I am, cannot, will not.
3. Use Conversational Vocabulary: Swap out heavy academic verbs for phrasal verbs. Instead of saying “I would like to inquire,” say “I wanted to ask.” Instead of “I am experiencing problems,” say “I’m having a hard time.”
4. Show Emotion: Friends express excitement, disappointment, and joy. Use exclamation marks (sparingly) and emotional adjectives: “I was absolutely thrilled to hear your news!”

The Perfect 4-Paragraph Informal Blueprint

Even though you are writing to a friend, you still need a logical, organized structure to cover the three bullet points provided in your exam prompt.

The Salutation

• Dear [First Name], (Always follow with a comma).

Paragraph 1: The Warm Opening (The Icebreaker)

Never jump straight into the main topic. Friends always do a little bit of small talk first.

• Example: “I hope you and the family are doing well! I’m so sorry I haven’t written in a while, but I’ve been incredibly busy with my new job.”

Paragraph 2: Transition & Bullet Point #1

Smoothly transition from the small talk into the main reason you are writing, addressing the first bullet point.

• Example: “Anyway, the main reason I’m writing is to tell you all about my upcoming trip to London…”

Paragraph 3: Bullet Points #2 and #3

Continue the story, making sure to explicitly answer the remaining bullet points. Invent fun, realistic details to show off your vocabulary.

• Example: “I’m planning to arrive on the 15th. Since you know the city so well, I was wondering if you could recommend a good place to stay? I’d love to find somewhere close to the city center.”

Paragraph 4: The Friendly Closing

Wrap up the letter with a warm final thought or a call to action.

• Example: “Let me know if you’re free to grab a coffee while I’m in town. I can’t wait to catch up properly!”

The Sign-off

Do not use “Yours sincerely” or “Yours faithfully.”

• Best options: Best wishes, / Warm regards, / Lots of love, / Take care,
• Sign your name: Use only your first name (e.g., John).

High-Scoring Informal Vocabulary (Band 7.0+)

To boost your Lexical Resource score, memorize these natural, native-sounding phrases for common informal situations:

Purpose	Formal (Do NOT use)	Informal (Band 7.0+ alternative)
Apologizing	I sincerely apologize for my absence.	I’m so sorry I couldn’t make it. / I feel terrible about missing it.
Giving News	I am writing to inform you that…	You’ll never guess what happened! / I’ve got some great news.
Asking for Help	I would be grateful for your assistance.	I was hoping you could do me a huge favor. / Can you give me a hand?
Saying Thank You	I am highly appreciative of your gift.	Thanks a million for the present! / I can’t thank you enough.

Top 3 Exam-Day Traps to Avoid

1. The “Slang” Trap: Informal does not mean inappropriate. Do not use internet slang or abbreviations like OMG, lol, u, r, wanna, or gonna. Write out full English words, just in a conversational style.
2. Forgetting to Read the Bullet Points: It is very easy to get carried away writing a fun story to a fake friend and completely forget to answer the second or third bullet point. Keep your eyes on the prompt!
3. Mixing Tones: Do not start with “Hey man, what’s up!” and then finish the letter with “I look forward to your prompt response.” Keep the friendly tone consistent from the first word to the last.
