Band 8 sample letter

Band 8183 words. Names and details are invented; write your own.

Dear Mr Henderson,

I am writing to express my serious concern regarding the unreliable bus service on the Number 42 route over the past fortnight. Despite the published timetable, the service has become increasingly unpredictable.

Specifically, the 7:45 a.m. bus has failed to arrive on four separate occasions this week, and when it does appear, it is frequently delayed by over twenty minutes. This lack of consistency has made it impossible to rely on public transport for my daily commute.

These persistent delays have had a significant negative impact on my professional life. As a result of arriving late to my office, I have missed several crucial morning briefings and have received a formal warning from my supervisor regarding my attendance. The stress caused by this uncertainty is becoming unsustainable.

I suggest that you review the current scheduling and investigate why these specific morning services are being cancelled or delayed. Furthermore, I would appreciate an update on what measures you intend to implement to restore reliability to this route. I look forward to your prompt response regarding this matter.

Yours faithfully,

Julian Thorne

Examiner's view

Why this scores well

A Band 8 response covers all three bullet points with specific, logical details while maintaining a professional and firm tone throughout. A common Band 6 mistake is failing to explain the personal impact clearly, often resulting in a generic list of complaints rather than a cohesive argument.

  • →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.
