How to Write Natural Dialogue: A Checklist for British Fiction Writers

Good dialogue does two jobs at once. It sounds like something a person would actually say, and it tells the reader something they could not have learned any other way. Most drafts fail the first test for the same reasons: too many greetings, too much information, not enough silence. Run the checks below over any conversation before you let another pair of eyes near it.

Cut the courtesies first

Real speech is untidy. People repeat themselves, answer a different question, lose the thread mid-sentence and say ‘anyway’ when they want to change the subject. You are not writing a transcript, though — read one back and you will see how quickly it becomes unreadable. Keep the mess that shows pressure or evasion, and delete the rest.

New writers often open a scene like this: ‘Hello, Sarah. How are you today?’ Then Sarah answers politely, and the scene stalls for two lines while nothing happens. Start later instead. ‘You’ve got that look on your face. What’s he done now?’ puts us in the middle of a relationship we can already feel.

Names are the other giveaway. People use each other’s names far less than new writers think — usually to open a conversation, to get attention, or to signal that something serious is coming. ‘Sarah. Sit down.’ That lands harder than any amount of “as you know, Sarah”.

British dialogue has its own traps here. We are a nation of hedgers. ‘I don’t suppose you’d mind…’ can mean ‘Do it.’ ‘That’s interesting’ can mean ‘I disagree entirely.’ If every character says exactly what they mean, the scene will sound American in the wrong way — or, worse, like an instruction manual. Let politeness do some of the lying. Let understatement carry the threat.

‘Is that your car?’

‘It’s parked outside, yes.’

‘On the double yellows.’

‘It’s only for a minute.’

‘It’s been there since Tuesday.’

Nobody says “I am angry with you for parking illegally.” The repetition of facts does it. The absence of a direct accusation makes the accusation sharper. That is the sort of restraint British fiction can use well, whether your setting is a London flat, a Welsh village or a Scottish island.

Give each character a voice you could recognise blind

Cover the speech tags and you should still know who is speaking. Three things do most of the work.

Vocabulary. One character calls a problem a “situation”; another calls it a “bloody mess”. One says “loo”, another says “toilet”, a third says “bathroom” and immediately sounds like they are visiting. Word choice reveals age, class, region and attitude faster than any description.
Rhythm. Some people speak in long, qualifying sentences that double back on themselves. Others fire out three words at a time. A barrister might talk in balanced clauses even when panicking. A teenager might answer everything with a flat “dunno” and a shrug. Punctuate accordingly. If every line is the same length, every character will sound like the same person wearing different hats.
Idiolect and tics. A favourite phrase, a habit of starting with “Look,” or “To be fair,” or “I mean,” a refusal to use contractions, a tendency to over-apologise. Use these sparingly. One tic per character is a signature; five is a pantomime.

Register matters too. A nurse talking to a patient, a nurse talking to a consultant and a nurse talking to her sister are three different speakers. They may share a vocabulary, but their formality, humour and sentence structure will shift. If your character’s voice never changes with the room, they will feel less like a person and more like a mouthpiece.

Let subtext carry the scene

Dialogue is not a delivery system for information. It is a negotiation. Characters want something: reassurance, permission, a confession, an exit. They rarely ask for it directly. The best conversations are full of loaded questions, false starts and answers that arrive a beat too late.

Try writing a scene in which two people discuss something trivial — a broken kettle, a missed train, whose turn it is to ring their mother — while the real subject sits underneath. If the real subject is an affair, a debt, or a death, the small talk will vibrate with it. If you have to name the real subject aloud, ask yourself whether you have earned it yet.

‘I’ll get the kettle.’

‘It’s not the kettle.’

‘I’ll get it anyway.’

Subtext also solves the problem of characters who explain the plot to each other. Two people who both know the history do not need to recite it. Let them refer to it obliquely. Trust the reader to lean in.

Use speech tags and action beats with restraint

Said is invisible. Asked is fine. Exclaimed, opined, retorted and chuckled are usually a sign that the line is not doing its job. If the words are angry, you do not need “he said angrily”. If the words are not angry, adding the adverb will not save them. Cut the adverb and sharpen the line instead.

Action beats can be more useful. They break up a long exchange, anchor us in the room and show what a character is doing while they speak.

‘You could have told me.’

She folded the tea towel into smaller and smaller squares.

‘I’m telling you now.’

Keep them short. A beat should not become a paragraph of stage direction. And do not use an action beat that contradicts the speech unless you mean it to. If someone nods while saying “No”, make sure the reader knows which signal to trust.

Read it aloud, then cut again

Read the conversation aloud. If you stumble, your reader will stumble. If you run out of breath, the sentence is too long. If you cannot tell who is speaking without the tags, the voices are not distinct enough. If a line exists only to tell us something the reader already knows, delete it.

Finally, check the shape of the exchange. Does it escalate, turn, or reveal? A good scene of dialogue is not a flat tennis rally. Something should change between the first line and the last: an alliance shifts, a secret leaks, a decision hardens. If nothing changes, the conversation may be charming, but it is not yet a scene.
