Dialogue is where many manuscripts come unstuck. The plot can be strong and the characters vivid, yet a reader stumbles on page three because a comma has landed on the wrong side of a quotation mark. British conventions are consistent and learnable, and once you know the handful of rules that matter, you can stop thinking about them and get back to the story.

What follows is the standard British approach used by most UK publishers. House styles vary, so if you are submitting, check the guidelines first — but the principles here will keep you consistent in the meantime.

Single or double quotation marks?

British fiction conventionally uses single quotation marks for spoken words, with double marks for a quotation inside a quotation.

'Where have you been?' she asked.

'He kept saying, "Not now," and walked off.'

This is the reverse of the American convention, and it is the single most visible difference between a UK and US manuscript. Some British publishers do prefer double marks, so take your cue from their style sheet. What matters more than which you choose is that the whole manuscript agrees. Mixed quotation marks are one of the first things an editor notices.

Punctuation sits inside the quotation marks

In dialogue, the full stop, comma, question mark and exclamation mark that belong to the spoken words go inside the closing quotation mark.

• 'I'll be back by six.'
• 'I'll be back by six,' he said.
• 'Are you coming?'
• 'Sit down!'

Where a question mark or exclamation mark already ends the speech, do not add a comma before the speech tag. Write 'Are you coming?' she asked, not 'Are you coming?,' she asked.

There is one tidy exception. When you quote a word or short phrase rather than a full line of speech, the punctuation belongs to your sentence, not the quotation, so it stays outside: He called her 'the boss'. This logical approach is genuinely British, and it trips up writers who have absorbed American habits.

Speech tags: quiet, correctly punctuated, sparingly used

A speech tag is the small phrase that identifies who is speaking: said, asked, whispered, replied. Keep the tag lowercase, and punctuate it as part of the same sentence.

'Not tonight,' she said. 'I'm tired.'

'If you're late,' he said, 'we'll go without you.'

Note the lowercase 'we' in the second example. The sentence continues after the tag, so no capital letter is needed. If the tagged speech ends there, the full stop goes after the tag.

On word choice: said and asked are invisible in the best sense. A page of characters who exclaim, retort, chuckle and hiss draws attention to the machinery. Use something more expressive only when it tells the reader something they could not otherwise guess. Adverbs attached to tags — she said angrily — are usually a sign that the dialogue itself needs to work harder.

Action beats are not speech tags

A character doing something is a separate sentence, so it takes a full stop, not a comma.

'I'm fine.' She shrugged and looked away.

'I'm fine,' she shrugged.

The second version is the mistake. You cannot shrug a sentence, and an editor will mark it every time. Verbs like shrug, smile, frown, laugh and nod describe physical actions, so they start a new sentence. The first version also reads better: the shrug shows the reader the evasion that 'I'm fine' is hiding.

New speaker, new paragraph

Every change of speaker starts a new paragraph, however short the line. This is not a stylistic preference; it is what allows readers to track a conversation without counting quotation marks.

'You're late,' said Mira.

'The bus broke down.' Tom dropped his bag by the door. 'Twice.'

'You could have rung.'

'I know.'

Keep a speech tag or an action beat in the same paragraph as the line it belongs to. If the same character carries on speaking after a brief action, that can stay in one paragraph, as with Tom above. What you must not do is put two different speakers in the same paragraph, even if the second line is only two words.

Decide early whether new paragraphs are indicated by a first-line indent with no blank line between them (common in printed British fiction) or by a blank line with no indent (common online). Both are fine. Switching between them mid-manuscript is not.

Interruptions, trailing off and nested quotes

Use a dash when speech is cut off, and an ellipsis when it fades out.

• 'I only wanted to—'
• 'I thought you might…'

UK publishers often set interruptions with a spaced en dash, while others use an unspaced em dash. Pick one and apply it throughout. For the ellipsis, the single ellipsis character is neatest, and most British fiction sets it unspaced: 'I thought you might…' rather than 'I thought you might …'.

For direct thought, many British editors prefer italics over quotation marks, which keeps inner life visually distinct from speech. Do not attach speech tags to thoughts — a thought cannot be said.

Five mistakes editors see most often

• A comma after a question mark or exclamation mark before a tag.
• A capital letter after a mid-sentence tag: 'Well,' She said.
• An action verb used as a speech tag: 'Fine,' he nodded.
• Two speakers sharing a paragraph.
• Quotation marks that change style halfway through the book.

Before you send it out

1. Search the manuscript for double quotation marks and convert any strays to single.
2. Read every tagged line aloud and check the comma sits inside the closing quote.
3. Check that the tag itself is lowercase and followed by a full stop only at the end of the sentence.
4. Look at each action beat and confirm it stands as its own sentence.
5. Scan the dialogue for paragraphs containing two voices, and split them.
6. Read a page of conversation without the tags and see whether you can still tell who is speaking. If you cannot, the problem is not punctuation.

Formatting dialogue well is a form of courtesy. It removes the small friction between a reader and the page, so that the only thing they notice is what your characters are saying to each other. Get the mechanics right once, and you will rarely have to think about them again.
