4.2. Formal & Semi-Formal Letters

When to Use Formal vs Semi-Formal

The difference is subtle: formal letters are more distant and impersonal; semi-formal letters are professional but slightly warmer.

Formal Letter Conventions

Opening and Closing

Note: "Dear Sir or Madam" — not "Dear Sir/Madam" or "Dear Sirs." And always capitalise "Sir" and "Madam."

Formal Letter — Worked Example

Question:

You recently stayed at a hotel and were very dissatisfied with the service. Write a letter to the hotel manager. In your letter:

• describe your stay and explain what the problems were
• say what the staff did (or did not do) to help
• state what you expect the hotel to do

Response:

Dear Sir or Madam,

I am writing to express my dissatisfaction with a recent stay at your hotel. I was a guest at the Grand Plaza from 5th to 8th March and experienced several significant problems during my visit.

Upon arrival, I discovered that my room had not been cleaned and the bed sheets had not been changed from the previous guest. Furthermore, the air conditioning unit was not functioning, which made the room uncomfortably warm throughout my stay. I reported both issues to reception immediately, but was told that no maintenance staff were available until the following day. Despite this assurance, no one came to address either problem during the remaining three nights of my stay.

Given the poor standard of service I received, I believe I am entitled to a partial refund. I paid the full rate of $200 per night for a room that was clearly below the standard advertised on your website. I would be grateful if you could look into this matter and respond within 14 days.

Yours faithfully, A. Liusie

Semi-formal letters are for people you know professionally. They're polite and respectful but slightly less stiff than formal letters.

How Semi-Formal Differs from Formal

Semi-Formal Letter — Worked Example

Question:

You have a problem at work that is affecting your performance. Write a letter to your manager. In your letter:

• describe the problem
• explain how it is affecting your work
• suggest a possible solution

Response:

Dear Mrs Patterson,

I am writing to bring to your attention a problem I have been experiencing in the office over the past few weeks, which I believe is affecting my productivity.

As you may be aware, the construction work on the floor above our department has been ongoing since early February. The noise levels during working hours are considerable, making it extremely difficult to concentrate on tasks that require focused attention. I have noticed that my output has decreased noticeably, and I have had to stay late on several occasions to complete work that would normally take me far less time.

I would like to suggest a possible solution. Would it be possible for our team to work from the meeting rooms on the third floor until the construction is completed? Alternatively, if remote working could be arranged for the most affected days, I believe this would help us maintain our usual standard of work.

Thank you for considering this request. I am happy to discuss this further at your convenience.

Yours sincerely, Adi Liusie
