Authoritative complaints letters have credibility and carry more weight

An authoritative letter is especially important for serious complaints or one with significant financial implications.

What makes a letter authoritative? Professional presentation, good grammar and spelling, firmness and clarity. Using sophisticated words (providing they are used correctly) - the language of a broadsheet newspaper rather than a tabloid - can also help to give your letter a more authoritative impression. What your letter looks like, its presentation, language and tone, can all help to establish your credibility - that you can be trusted and believed, that you know your facts, and that you probably have a point.

So think about your letter layout - use a letterhead preferably - ensure the name and address details of the addressee are correct, include the date, keep it tidy, well-spaced, and print your name under your signature.

If you copy the letter to anyone show that this has been done (normally by using the abbreviation 'c.c.' with the names of copy letter recipients and their organisations if appropriate, beneath the signature.) If you attach other pages of details or photocopies, or enclose anything else such as packaging, state so on the letter (normally by using the abbreviation 'enc.' the foot of the page).

When people read letters, rightly or wrongly they form an impression about the writer, which can affect response and attitude. Writing a letter that creates an authoritative impression is therefore helpful.
