Formal letter format in the UK (with examples)

Arrange the addresses and date

Put your sender address at the top right, or at the top left if you prefer a fully left-aligned layout. Write the date clearly underneath, using an unambiguous UK style such as “7 September [year]”. Add the recipient's name, organisation where relevant, and complete postal address on the left below your sender details.

Keep address blocks separate. Include the building number and street, town in capitals and full postcode. For window envelopes, the recipient block must stay in the required window area, regardless of your preferred template.

Choose a greeting and matching closing

When you know the recipient's name, “Dear Mr Surname” or “Dear Ms Surname” can be followed by “Yours sincerely”. Use the person's stated title where known, and do not guess a title if you are unsure. A known full name can be a clearer choice when no title has been supplied.

When the name is unknown, “Dear Sir or Madam” pairs with “Yours faithfully”. You can also address an identified team. Add your name and any required signature, checking organisation-specific signing instructions.

Add a useful subject line

A short subject line makes the purpose easy to identify. Place it after the greeting and before the main text, or follow the recipient's preferred format. Include a relevant order, account or case reference when it helps the organisation find the matter, but avoid unrelated personal details.

Try “Complaint about order [reference]” or “Request for a copy of [document]”. Keep the heading brief, check reference numbers and make sure it matches the request at the end.

Use a simple three-part structure

Start by explaining why you are writing. In the middle, give the facts the reader needs in a sensible order: relevant dates, what happened and any previous attempts to resolve the issue. Finish by stating the action you want, such as a written explanation, replacement document or reply to a specific question.

Keep paragraphs short and use plain English. A formal tone does not require complicated words or aggressive language. Distinguish facts from assumptions and avoid claims you cannot support. If you suggest a response date, make clear what you are requesting rather than presenting an invented legal deadline. This guide is not legal advice.

Short complaint-letter example

Replace these placeholders with accurate facts and add both addresses and the date above. Follow any formal complaints procedure and required contact route rather than relying only on this sample.

Mention supporting documents in the body and keep copies. Avoid including unnecessary sensitive information or demanding a particular remedy without explaining the problem.

Dear Ms [Surname],

Subject: Complaint about order [reference]

I am writing about [item or service] received on [date]. The problem is [brief factual description]. I contacted [team] on [date], but [current position].

Please explain how you propose to resolve this issue. I enclose a copy of [relevant document] for reference.

Yours sincerely,
[Your name]

Short notice or request example

A request should identify the document or action clearly enough for the recipient to respond. A notice may have specific contractual or legal requirements, so check those separately before using a general format. The example below is an ordinary request, not a template that establishes legal validity or satisfies every notice rule.

Dear Sir or Madam,

Subject: Request for [document or information]

Please send me a copy of [specific document] relating to [relevant reference or period]. My reference is [reference].

Please reply to the correspondence address shown above. If you need further information to identify the record, please tell me what is required.

Yours faithfully,
[Your name]

Review the complete document and keep a copy

Check meaning first, then names, addresses, dates, references and the requested action. Review attachments and page order. Save the approved final version, not only an earlier draft.

If you convert a Word document to PDF, inspect the actual converted pages because page breaks or spacing can change. An uploaded PDF must already place the full recipient address in the left envelope window area; entering recipient details in the form does not move it. Keep sender details clear of that area and check the final paragraph is present.

Use the online writing flow

Select “Write a letter”, enter your text and UK recipient details, then review the rendered PDF, every page and the total before payment. You can also upload a prepared PDF. Pricing is £2.99 for the first page plus 35p per extra page, including printing, an envelope and UK second-class postage.

Processing and dispatch status is not delivery tracking. Ordinary post provides no guaranteed arrival or proof of delivery, so check whether a time-sensitive notice requires another delivery method. A well-formatted letter and an order confirmation do not by themselves prove that a legal or contractual requirement has been met.

Frequently asked questions

When should I use Yours sincerely?

Use it when addressing a named recipient. Yours faithfully is the conventional closing when the recipient's name is unknown.

Does my address have to be on the right?

No. Top right is common, but a consistent left-aligned layout is also suitable. Keep the recipient address in the required envelope window area.

Can I use these examples as legal notices?

They are general writing examples, not legal advice. Check any specific notice wording, signature, timing and delivery requirements separately.
