What is an official letter?

An official letter is also known as a formal letter. It’s a professionally written document that informs the recipient of any official information from a business or organisation.

Here are some official letter examples:

• A formal letter of communication from a business, such as correspondence with clients or partners
• A professional cover letter for a job application
• A letter of recommendation or job reference
• A letter of resignation from an employee to employer
• A project proposal
• An official written warning or complaint
• An official update on regulatory issues.

What to include in an official letter.

Luckily, formatting an official letter is relatively easy. Formal letters follow a common standard that is simple to recreate – whatever the scenario.

Here are some of the key elements to include when setting out and writing an official letter:

1. Your name, address and contact information.

Your name and address are the first things on the page. This could be your personal or company name and address, depending on who you’re writing on behalf of.

The address should be at the top of the page and aligned on the right-hand side. Follow these steps:

• Write your name first and then put your address underneath.

• Each line of the address should have its own line, following the standard format.

• Leave a line space beneath your address.

• Beneath this, put your contact details, including your phone number and email address.

Make sure all information is up to date if you plan on creating a business letter template to reuse.

2. Date.

Beneath the address, add the date in full and in the UK date format. For example, 20th January 2026. The date should be right-aligned with a line space beneath it.

3. Recipient’s address.

Next, you need to add your recipient’s full name with their correct title and full address. The address can be their place of work, if more appropriate. You can include the recipient’s telephone number and email address too, but this isn’t essential.

Leave a line space beneath this address – it should be one line below your contact information but aligned to the left.

4. Reference.

If the formal letter is responding to a matter that requires a reference, you can include this near the top. Add ‘REF’ followed by the number. You should include the reference before the salutation.

5. Salutation.

The salutation is how you greet the recipient. It sets the tone and mood for your formal letter, and how you write it depends on how well you know who you’re writing to.

Typically, you would use a formal greeting of ‘Dear Mr/Mrs/Ms [Surname]’. If you know their first and last name but are unsure on their pronouns, you can write their full name without the title – for example: ‘Dear Ashley Smith’. However, if you are unsure of the recipient’s surname, you can simply write ‘To Whom It May Concern’, or ‘Dear Sir or Madam’.

The salutation sits on its own line, aligned to the left of the page.

6. State your reason for writing.

Beneath the salutation, you can begin writing your official letter. Keeping to British business etiquette, ensure that your tone remains formal, polite, and professional. Use paragraphs to organise your messages and use proper grammatical rules to ensure your letter is written in a polished and comprehensible manner.

If you haven’t met them before, you can introduce yourself. E.g. ‘My name is [Name], and I am writing to you today because…’. Starting your letter with who you are and what the letter is about will help give the reader some insight into the official matter and ensure they understand your intent.

7. Body of the letter.

The next paragraph should then expand on the introduction. If you’ve said you’re writing to express interest in a job position, this is where you can explain what experience you have. For example, you can say, ‘In my 10 years’ experience in the sales industry, I have developed valuable skills such as…’.

Keep expanding on each statement you make and provide evidence until you feel like you’ve made your point.

8. Closing statement.

Conclude your official letter with a polite and formal statement. You should wrap up and repeat your main points to add emphasis and remind the reader of the letter’s purpose.

Once you’ve finished the letter, you can then add a closing signature. Use ‘Yours faithfully’ if you don’t know the recipient, or ‘Yours sincerely’ if you’ve addressed them by name.

Other options include:

• Sincerely yours

• Best regards

• Thank you

• Respectfully yours.

Leave a space between your closing statement and the previous paragraph, and another after your closing statement – before your signature.

9. Your signature.

Your formal letter should always include a handwritten or electronic signature after your closing statement. Beneath your signature, ensure that your full name is clearly typed out. You can import a digital signature or print your letter and sign it by hand.

10. Enclosed documents.

If your formal letter includes additional documents or information, such as a supporting portfolio or evidence, make sure that you list these attachments at the end. For example, you may include an invoice, job offer, letter of intent or resume with a formal letter.

How does a UK letter format differ from other countries?

How you format certain elements of a formal letter can vary depending on which country you’re sending the letter to. Take salutations, for example. In the UK, there’s no punctuation after the addressee’s title. In the US, the title is followed by a full stop, and the salutation is finished with a colon.

• UK: Dear Mrs Williams

• US: Dear Mrs. Williams:

The US is also less strict when it comes to matching salutations to closes. The most common closes are ‘Sincerely yours,’ and ‘Yours,’ – both of which are followed with a comma.

There are also some country-to-country nuances with date formatting. For example, in the UK, you would expect to see the date written as 20 January 2026, but in the US, this would be written as January 20, 2026. In the US, the month precedes the day, which is also separated from the year with a comma.

If you’re sending letters internationally, don’t forget to include the destination country on the final line of the recipient’s address on the envelope. If you’re sending to Europe, remember to write the postcode to the left of the town. For example, 70123 Paris.

Tips for using a formal letter format in the UK.

Along with the elements discussed above, official letters in the United Kingdom have a particular format and style that is quintessentially British. Here are some tips for formatting an official letter for UK or British audiences:

• Use a polite, direct tone. A letter addressing a British audience will always carry a certain tone, one which is polite and to the point. Stick to the topic and try not to come across as over-friendly or too casual.

• Consider the audience. Once you’ve understood exactly who you’re writing to, it should help you hone the tone and overall level of formality in your letter.

• Remember the letter’s intention. Next, pin down the purpose of your letter. A letter for a job application will be quite different from a letter used in general business correspondence or a complaint letter to a company. Browse these letter templates for help formatting your letter.

• Get your message across. Try to make your points as quickly and succinctly as possible. Use additional documentation for further details. This will help the recipient handle large amounts of information with ease.

• Proofread. Before you send anything, ask someone else to read it. Get them to check for errors and clarify if your message is clear. Use their feedback to improve the tone, clarity, and structure of your formal letter.

• Make it engaging. Keep your letter succinct and avoid unnecessary waffle. You could also consider using the active voice. Depending on the purpose of the letter, you may decide to vary the structure to keep the reader engaged.

What fonts should I use for official letters?

The font you choose for any kind of written communication can have a surprisingly important effect on how your message is received. The right font can command attention, trigger action and encourage the reader to continue. The wrong font risks coming across as unprofessional, unserious, or it could even be illegible.

Formal letters need to be written in fonts that are easy to read and scan – and not come across in a raised tone. It’s best to err on the side of caution and pick a widely used and recognised font.

Times New Roman or other serif fonts are generally accepted for all official letters. Serifs are small lines attached to letters that give the typeface a traditional and authoritative appearance. Serif fonts are also typically more legible on a smaller scale. Alternatively, professional sans serif fonts include Arial and Calibri.

How do I write for different audiences?

To write for different audiences, you need to adjust your tone and style to match the intent of your letter. It’s never a one-size-fits-all. For example, the way you write an official update on behalf of a legal organisation or government body will be very different to a formal, professional cover letter to a prospective employer.

When writing any form of official letter, consider:

• Who your recipient is

• The seniority of your recipient

• How well you know the recipient

• The intent of your letter

• The gravity of the subject of your formal letter.

You can then adapt your formal writing style to suit. But stay professional, clear and concise in all your formal correspondences.

What not to include in your official letters.

We’ve touched on all of the elements you need to include in your official letter, but now we need to mention what should be avoided.

• Casual greetings in the salutation. You should avoid calling anyone ‘Miss’. Instead, opt for ‘Ms’. You should also avoid ‘Hi’, ‘Hello’, or ‘Hey’ as a greeting.

• Not finishing sentences. Make sure everything is wrapped up. You should make a point, provide evidence and expand.

• Being overly formal. Being too formal can cause confusion and lead to the recipient misunderstanding your intent.

• Complicated font. Opt for an easy-to-read, simple font that is clear and concise.

• Long sentences and paragraphs. Short sentences and paragraphs that get straight to the point will make your letter easier to read and understand.

• Adding colour. Keep the font black on a white page so it’s easy to read.

Official letter writing – common mistakes.

Accidental errors are natural, but it can come across as unprofessional in formal environments. When it comes to writing official letters, there are some common pitfalls to watch out for. These include:

• Writing in the passive voice. Particularly important to avoid when writing legal documents, a passive voice can sometimes cause confusion. Instead, use the active voice and keep your points as direct as possible.
• Excessive wordiness. Watch out for unnecessary filler words that don’t add clarity to your points. Instead, streamline your formal letter and keep it concise.
• Incorrect homophones. These are words that sound the same but have very different meanings. A thorough proofread should help to spot any that may have slipped through in your formal writing. For example:
  • ‘Ensure’ and ‘insure’
  • ‘Their’, ‘there’, or ‘they’re’
  • ‘Formerly’ or ‘formally’.
• Using jargon. When writing a formal letter, it’s important to be mindful of your recipient’s existing knowledge. Make sure you’re using laymen terms that are widely understood, but avoid overly simple, patronising language.

• Not proofreading. Take the time to review your formal letter before sending it. A simple typo or spelling mistake on a legal letter can affect the tone of the entire document.

Key points to consider in your official letter layout.

When it comes to planning your formal letter format, you should always make sure the font, layout, and images suit the style of your document.

• Font. Typically, most letters will be written in Times New Roman or Arial font sizes 10 to 12. Make sure you choose a font that is legible and keep the font size the same throughout. Use a bold or italic effect for emphasis. Learn more about the importance of pairing fonts for maximum impact.

• Layout. Follow the standard layout of a formal letter to clearly communicate with your recipient and encourage a quick response. If you want to create a unique letterhead in line with formal letter layouts, you can do so with the help of Adobe Express.

• Imagery. If you use imagery, for example a logo of your company, make sure you format it correctly. This includes adjusting the size of the image so that it doesn’t dominate the letter or affect the structure.

• Customisation. If you’re sending an official letter on behalf of your organisation, you can use Adobe Express to apply your brand style (where appropriate). This ensures that all of your brand communications remain consistent. Just make sure that any branding elements don’t detract from the letter itself.
