A simple structure that makes every letter clear, confident and easy to read
Most people overthink letter writing. They worry about length, tone, where to begin, or how formal to sound. The truth is, almost every letter you will ever write can be built from the same simple structure. It works for councils, companies, schools, employers, MPs and even personal matters.
This structure is known as the 3 Paragraph Rule, and it is one of the easiest ways to learn how to structure a letter in the UK without waffle or confusion. If you follow it, your message becomes clear, direct and impossible to misunderstand.
Here is how it works.
Paragraph One: What happened
Start with the facts. Keep emotion low and clarity high. A reader cannot help you unless they understand the situation straight away.
Include:
• What happened
• When it happened
• Any reference numbers
• Who you spoke to or dealt with
• Short, relevant details only
If your letter is a complaint or request, this paragraph sets the foundation. As the Plain English Campaign advises, the opening must be simple and factual so the reader knows exactly what they are dealing with.
Example:
“I contacted your customer service team on 12 February about the faulty water heater supplied to my property. I was told a replacement would arrive within seven days, but I have not received an update.”
Short, calm and clear.
Paragraph Two: Why it matters
This is the paragraph people often forget. Facts alone do not show impact. Councils, companies and employers prioritise issues based on how they affect real people.
Explain briefly:
• How the situation affects you
• Any financial or personal consequences
• Any previous attempts to resolve the issue
Avoid long stories. One or two solid sentences are enough.
The Citizens Advice guidance on complaints encourages people to include the practical effect of the issue so decision-makers understand urgency.
Example:
“The ongoing delay has left my home without hot water for three weeks, which is affecting daily routines. I have also had to pay for temporary electric heaters to wash and clean.”
This is not emotional writing. It is relevant impact.
Paragraph Three: What you want
This is the most important part. A letter without a request is not a letter. It is a vent.
State clearly what you want to happen next, such as:
• A refund
• Repairs by a certain date
• A written explanation
• A review of a decision
• Compensation
• Confirmation in writing
Clear requests reduce back-and-forth messages and help the reader respond faster. This follows the UK Government’s own approach to correspondence, shown in their official letter standards.
Example:
“I would appreciate written confirmation of when the replacement unit will be delivered, along with reimbursement for the temporary heating costs.”
You have told them what happened, why it matters and what you want next. That is the complete structure.
Why the 3 Paragraph Rule works
This format works because it mirrors how decision-makers think.
They need:
Context
Impact
Action
Anything extra becomes noise. The 3 Paragraph Rule keeps the letter focused, readable and easy to process. It also prevents long emotional drafts that weaken your point.
Whether you are writing a business letter, a company complaint, a benefits appeal, a workplace request or an MP enquiry, this structure delivers calm authority and professionalism.
It is also one of the fastest ways to learn a professional letter format without needing templates or complicated instructions.
Example: The 3 Paragraph Rule in action
Here is a complete short letter using the method:
“I am writing regarding the parking charge issued on 4 March at the West Quay Retail Park. I was parked in a marked disabled bay and displayed my Blue Badge correctly.
The penalty notice appears to have been issued in error. This has caused unnecessary worry, and I have had to gather evidence to dispute the charge.
Please cancel the penalty and confirm this in writing. I have attached photos showing the Blue Badge in clear view.”
Clear. Short. Effective.
When to break the rule
Most of the time, you will not need to. However, you may add extra paragraphs if:
• You are attaching evidence
• You need to list events in order
• You are responding to several points
Even in longer letters, the first three paragraphs should still follow the rule.
When you are too stressed or unsure
If the issue is sensitive, complicated or emotional, the rule can be hard to follow. That is why many people ask for help before contacting councils, companies or employers.
