What is persuasive writing in the UK? A clear guide to writing to argue with impact

Persuasive writing isn’t just for politicians and lawyers. Whether you’re writing a complaint letter, pitching an idea at work, or sitting an English Language GCSE paper, knowing how to argue your point persuasively is a critical skill.

At LetterLab, we write persuasive letters every day and we know what works.

Here’s how to master persuasive writing in the UK context, with practical steps, examples, and the most trusted techniques used by expert writers.

What is persuasive writing (or writing to argue)?

Persuasive writing is a style of communication that aims to influence the reader’s opinion, change their behaviour, or encourage a specific action. It uses logical arguments, emotional appeal, and strong evidence to convince the audience.

In UK schools, this is often called “writing to argue” and is a key component of the English Language curriculum. But in real life, it shows up everywhere: in cover letters, appeals, political speeches, product descriptions, and public campaigns.

The key features of persuasive writing

If you want your writing to persuade, it needs to do a few things very well:

• Have a clear point of view: State your position early and stick to it.

• Use evidence: Support your points with facts, examples, statistics, or real-world anecdotes.

• Anticipate objections: Acknowledge opposing arguments and counter them intelligently.

• Use persuasive language: Words like “surely”, “clearly”, “undeniably” help steer the reader.

• Structure it logically: Use paragraphs to build your case step-by-step, leading to a strong conclusion.

  
  

A proven structure: The 1-3-1 model

A popular structure for persuasive writing is the 1-3-1 format:

• 1 introduction – Clearly state your position or argument.

• 3 body paragraphs – Each covering a different reason or piece of evidence.

• 1 conclusion – Sum up and leave a lasting impression.

  
  

This simple structure is widely used in UK classrooms and is just as effective in letters, speeches, and essays.

Top persuasive writing techniques (with examples)

Here are five techniques used by expert letter writers and speechwriters across the UK:

1. Rhetorical questions “Should hardworking families be punished for rising rents?” Makes the reader think and encourages agreement.

2. Repetition “We need action. We need fairness. We need change.” Emphasises urgency and creates rhythm.

3. Tripling “It’s fast, affordable, and reliable.” Grouping ideas in threes is memorable and effective.

4. Emotive language “This heartless policy has left children hungry.” Appeals to emotion to sway opinion.

5. Direct address “You have the power to make a difference.” Makes the reader feel involved.

What UK schools teach about persuasive writing

If you're revising for your GCSEs, persuasive writing is tested as part of English Language Paper 2. According to the AQA English Language specification, students are expected to:

• Present a convincing point of view

• Use appropriate tone, register, and rhetorical devices

• Write for specific audiences and purposes

  
  

And it’s not just exams. These skills are useful for UCAS personal statements, job applications, and even writing a formal letter to your MP.

A real-world example

One of our clients came to us with a housing dispute. They were being evicted unfairly and needed to challenge the council's decision. We helped them write a persuasive appeal letter that:

• Referenced specific housing laws from Citizens Advice

• Highlighted the impact on the client’s disabled child

• Suggested reasonable alternatives

  
  

The result? The eviction notice was overturned within two weeks.
