Getting Business Letters Right

Business letters are important both as a tool for customers who want to contact a company. They also allow companies to respond to customers or to initiate contact with a customer or another company.

It’s a fact that the written word can often be so much more powerful than the spoken word. There is nothing which will irk your customers more than if they get a poorly presented letter.

As a company, it’s important that you take care with all of your outgoing business correspondence, especially letters.

Addressing the Letter

When beginning the letter, we’re going to assume it’s being sent on company letter-headed paper. That means there will be no need to include the company’s name and address.

You should begin by typing the recipient’s name and address at the top on the left hand side. Use titles where appropriate e.g ‘Dr’, ‘Sir’, Reverend etc. followed by their first name or initial then last name. If you don’t know a female’s title, use Ms.

Their address should go immediately underneath and, following a space below, then comes the date in UK format, e.g. 1 June, 2020 not June 1st 2020 although some companies start with the date then the name and address.

You should begin with Dear…, followed by the person’s title (Mr Mrs Miss etc) and last name.

Signing Off

Providing you know the name of the intended recipient, you should end your letter with ‘Yours sincerely’.

If, for any reason, you don’t have the recipient’s name, you begin with ‘Dear Sir or Madam’ and end it with ‘Yours faithfully’.

However, in delicate situations such as responding to a query or complaint, you should never use ‘Dear Sir or Madam’ and always respond to a name.

Obviously, depending on the style and tone of letter alongside your familiarity with the recipient, it is acceptable to end letters with phrases such as ‘Best regards’.

However, you only do that if you have established a good relationship with the recipient over a period of time. This type of ending should never be used in a business letter from a company to a customer.


If you’re writing to somebody with regards to an account or a specific matter, before you even get to the ‘Dear Mr Smith’ part, you should put the account number and / or the matter in bold type and centred on the page so that the recipient is clearly aware of the reason that you’re writing to them.


If the letter contains sensitive information or if it’s to go to another company and you do not want it to be intercepted first by a secretary, you must mark the envelope ‘Private and Confidential’.

This will help ensure it’s only seen by the recipient themselves.

Likewise, if you receive a letter that requires a response and has been marked private in this way, your response envelope should be marked ‘Private and Confidential’ as well.


Always adopt a formal approach when writing a business letter. This doesn’t mean over-elaborating and using ‘big’ words. In fact, keep it simple but avoid using slang and over familiar expressions.

Make sure that you have clearly thought through what you want to say and the order in which you want to say it.

This will help make sure you’ve covered all your points, and that it makes sense and can’t be misinterpreted.

As a general rule, never use humour in a business letter unless it’s to go to somebody whom you’ve known for a long time and who you know would appreciate a light-hearted comment or two. However, in general, business letters and humour do not mix together well.


You should not delay when responding to a business letter.

Unless there is an understanding in place whereby, for example, it’s stated that a person would receive a response within 14 to 28 days, you should always aim to answer a letter within no more than 5 working days.


Always end your letter with a handwritten signature, followed underneath by your typed name and job title, if appropriate.

Don’t be tempted to save time by using a photocopy of your signature. It smacks of unprofessionalism and gives off the impression of both the sender not being bothered to find the time to sign it.

Even more worryingly, many recipients, upon seeing a photocopied signature, often feel that they’re just getting sent a bog standard form letter that the sender hasn’t probably had anything to do with for months.

Final Touches

Always make sure you do a thorough proof read of your letter before putting it into the envelope to check for spelling and grammatical errors. There is nothing worse than reading a letter from a company containing such errors.

By following the guidelines above, you can be sure that, whether your letter contains good, bad or indifferent news, you will be perceived in a professional manner and that your correspondence will be taken seriously.
