Band 8 sample letter

Band 8176 words. Names and details are invented; write your own.

Dear Sir/Madam,

I am writing to express my profound dissatisfaction regarding the repair service performed on my MacBook Pro last week. My device was submitted to your branch on 12 October for a critical screen replacement after the display began flickering intermittently and eventually went completely black.

Upon collecting the machine yesterday, I was dismayed to find that the screen flickers even worse than before. Furthermore, the technician failed to secure the base casing properly, leaving a noticeable gap on the left side, and the internal cooling fan is now making a persistent grinding noise that was not present previously. It appears the device was handled with extreme carelessness.

I expect you to rectify these issues immediately by conducting a thorough repair at no additional cost. If the hardware cannot be restored to full working order within three working days, I request a full refund of the £250 service fee so that I may seek assistance from a certified service centre elsewhere.

I look forward to your prompt response regarding this matter.

Yours faithfully,

Jonathan Sterling

Examiner's view

Why this scores well

A Band 8 response fully addresses all three bullet points with a clear, professional tone and logical paragraph structure. Common Band 6 errors include failing to provide specific details about the repair issues or using an inappropriate informal register.

→Write to an organisation or someone you do not know: open with Dear Sir or Madam, close with Yours faithfully.
→If you know the person's surname, use Dear Mr or Ms and close with Yours sincerely.
→No contractions, no slang; polite indirect requests such as I would be grateful if you could.
