The role of the sub-editor in a UK newsroom
Sub-editing — known informally as “subbing” — is the editorial process of preparing a journalist's copy for publication. The sub-editor is the final checkpoint between a reporter's draft and the reader. Their job is simultaneously legal, linguistic, factual, and visual: they must ensure the copy is accurate, defensible, readable, and correctly formatted for the platform on which it will appear.
In UK print newsrooms, subs traditionally worked on the stone — the physical page layout — but the role has evolved significantly in the digital era. Many titles now operate combined sub-editing and production desks where the same person checks copy, writes the headline and standfirst, selects or crops images, writes captions, adds SEO metadata, and publishes to the CMS. The NCTJ recognises this breadth in its sub-editing qualifications, which cover both traditional and digital disciplines.
The value of skilled subbing extends beyond catching typos. A sub who spots a potentially defamatory passage, an unverified statistic, or a contempt risk before publication protects the title from legal action and protects the journalist's reputation. The BBC Editorial Guidelines describe this layer of editorial oversight as central to maintaining accuracy and impartiality — standards to which all IPSO-regulated publishers are also bound.
House style: the sub's first reference point
Every UK publication maintains a house style — a set of conventions governing spelling, capitalisation, hyphenation, numbers, titles, dates, and usage that ensure a consistent voice across all content. The Guardian Style Guide is one of the most widely used public references; the BBC also publishes its style guidance as part of its Editorial Guidelines. Most publishers supplement these with internal style sheets covering brand-specific terminology and local usage.
A sub-editor's first pass through copy applies the house style systematically. Common areas of variation across UK publications include: whether to use “per cent” or “%”, how to style monetary amounts, whether job titles are capitalised, and how to handle numbers (spell out one to nine, or one to ten?). Consistency within a piece and across the publication is the goal, not adherence to any single external authority.
Common house-style checks
- Numbers: words or figures? Threshold (nine/10) and exceptions (ages, percentages, page numbers).
- Capitalisation of job titles, institutions, and proper nouns — apply consistently throughout.
- Hyphenation of compound adjectives: “decision-maker” vs “decision maker” — check the style sheet each time.
- Dates: “June 13, 2026” vs “13 June 2026” — UK publications generally favour the latter.
- Titles: “Dr” or “Dr.”? “Mr” or “Mr.”? UK style typically omits the full stop.
- Quotation marks: single or double? UK style conventionally uses single quotes with doubles for quotes within quotes.
- Preferred spellings: judgement/judgment, organise/organize — apply the house preference throughout.
The fact-check loop
Sub-editors are not passive proofreaders — they are active accuracy checkers. The fact-check loop is the systematic process by which a sub interrogates the verifiable claims in a piece of copy against source material. This is not an exhaustive academic review, but a proportionate check focused on the claims most likely to be wrong and most damaging if wrong.
The BBC Editorial Guidelines require that all material facts be verifiable and that sources be identified to editorial management even where they are not named publicly. IPSO's Editors' Code requires that publications take care not to publish inaccurate, misleading or distorted information. These obligations fall on the publisher, not merely the reporter — making the sub's fact-check loop a compliance requirement, not just a quality preference.
- 1Identify all verifiable claims: Statistics, named individuals, dates, organisations, locations, titles, and quoted statements. Flag each one mentally as you read.
- 2Prioritise by risk: Claims about named individuals (especially negative ones), specific figures, and novel assertions carry the highest risk if wrong. Check these first.
- 3Check against the supplied source material: Reporters should supply notes, recordings, documents, or URLs. The sub checks the copy reflects the source accurately — including that quotes are not taken out of context.
- 4Spot-check independently: For significant statistics or biographical details, verify against an independent authoritative source (official statistics, Companies House, Hansard) rather than relying solely on the reporter's source.
- 5Query the reporter: Raise all queries clearly and specifically. “Can you supply a source for the £2.3m figure in paragraph four?” is a better query than “please check facts”.
- 6Document the resolution: Note what was queried and how it was resolved. If a claim was removed or changed as a result of fact-checking, a brief note on the file protects both sub and reporter.
Legal-flag escalation
UK media law creates four categories of risk that sub-editors must be trained to recognise: defamation, contempt of court, privacy, and copyright. The threshold for escalation to a senior editor or legal adviser varies by publication size and the gravity of the potential risk, but the principle is consistent: when in doubt, flag it up rather than proceed.
Defamation
Any statement of fact about an identifiable person that could damage their reputation requires a defence. The three main defences under the Defamation Act 2013 are truth, honest opinion, and publication on a matter of public interest. If the copy makes a factual assertion about an individual that the reporter cannot substantiate with evidence, it must be revised or removed before publication.
Contempt of court
Once criminal proceedings are active — typically from the point of arrest — the Contempt of Court Act 1981 creates a strict liability risk for coverage that creates a substantial risk of serious prejudice to a fair trial. Subs must identify when a case is active and apply the appropriate restraint to coverage of prior convictions, character, or evidence not yet heard in court.
Privacy
The law of misuse of private information (derived from Article 8 of the European Convention on Human Rights as incorporated by the Human Rights Act 1998) protects individuals' reasonable expectation of privacy. Images taken in private settings, medical details, and information about children are particularly sensitive. The IPSO Editors' Code Clause 2 sets the regulatory standard for UK publishers.
Copyright
Reproducing substantial portions of third-party copy, images, or other creative works without a licence or fair-dealing justification risks copyright infringement. Subs should query the sourcing of any substantial quotation from another publication and ensure image licences cover the intended use.
When a legal flag is raised, the escalation path typically runs: sub-editor → chief sub or production editor → editor or deputy editor → in-house lawyer or retained media law firm. The copy is held until the risk is assessed and, where possible, mitigated through rewriting, additional evidence, or removal of the problematic passage. The NUJ's guidance on legal issues recommends that journalists keep contemporaneous notes of all legal queries and their resolution.
Headline writing
Writing headlines is one of the most skilled elements of sub-editing. A headline must accurately reflect the story, attract the reader, fit the available space (in print) or optimise for search and social sharing (digitally), and comply with the house style. It must also be legally safe — headlines are read as standalone statements, and a defamatory headline is actionable even if the body text is defensible.
Headline-writing principles
- Accuracy first: the headline must be a fair summary of the story. Never promise what the story does not deliver.
- Active voice: “Police charge man with fraud” reads better than “Man charged by police with fraud.”
- Present tense for print, past or present for digital: “Chancellor raises rates” is conventional headline style even for yesterday\'s news in print.
- Avoid the definite article at the start where possible — it wastes space and weakens impact.
- In digital contexts, lead with the keyword the audience is likely to search for. Check the style guide for guidance on when SEO should yield to editorial judgement.
- Do not use quotation marks to distance the publication from a claim — “MP ‘took bribes’” still attributes the allegation to the publication in law. Use “claims” or “alleges” in the attribution verb instead.
- Puns and wordplay: acceptable in tabloid and feature contexts where house style permits; generally avoided in hard news headlines and digital-first content.
- Cross-check the headline against the intro and the whole story before finalising — inconsistencies between the headline and the body are among the most common IPSO complaints.
Picture choices
Sub-editors working on digital and print production desks are frequently responsible for selecting or approving images. Picture selection is not merely aesthetic — it carries editorial, legal, and ethical implications. The IPSO Editors' Code, the BBC Editorial Guidelines, and the NUJ's ethics guidelines all address the use of images, particularly in sensitive contexts.
- Licence check: confirm the image is licensed for the intended use (web, print, or both) and that the licence has not expired. Agency images (PA, Reuters, Getty) carry licence terms that must be observed.
- Accuracy: the image must genuinely illustrate the story. A stock image used to represent a specific individual or event must not create a false impression.
- Privacy: images of individuals taken in private settings, medical contexts, or involving children require particular care. Consent and the reasonable expectation of privacy are the key tests.
- Dignity: the IPSO Editors' Code requires sensitivity when reporting on grief, shock, or trauma. Graphic images of death or serious injury must clear a high public-interest threshold.
- Identification: where an image could identify an individual who has not consented to be identified — particularly in crime or court reporting — consider pixelation or cropping.
- Representation: avoid images that stereotype or demean individuals by reference to their race, religion, gender, sexual orientation, disability, or other protected characteristics.
- Caption accuracy: every image must carry an accurate, attributable caption. A caption that misidentifies a person or misrepresents an event is as damaging as inaccurate body text.
Writing captions
Captions are among the most widely read elements of any article — many readers scan headlines, captions, and pull quotes before committing to the body text. A caption must accurately describe the image, identify the people or subjects depicted where relevant and appropriate, and attribute the photographer or agency. It must not contain information that is not evident from or clearly related to the image.
Caption checklist
- Does the caption accurately describe what is shown in the image — not what you assume or wish were shown?
- Are named individuals correctly identified and is their identity verifiable?
- Is the photographer or agency credited in accordance with the licence terms?
- Does the caption contain any potentially defamatory, contemptuous, or privacy-infringing material?
- Does the caption add information value beyond the image, or merely repeat the headline?
- Is the caption written in the tense and style prescribed by the house style guide?
- If the image is archive or file photography, does the caption make that clear to avoid misleading the reader?
NCTJ sub-editing qualifications
The National Council for the Training of Journalists (NCTJ) is the primary awarding body for journalism qualifications in the UK. Its Diploma in Journalism includes sub-editing as a core discipline, and it also offers a standalone Certificate in Sub-Editing for those seeking to specialise in the editorial production role.
The NCTJ sub-editing syllabus covers: applying house style and language skills; law for journalists (including defamation, contempt, privacy, and copyright); production skills for print and digital platforms; headline and caption writing; and copy-tasting — the editorial judgement of assessing and prioritising incoming copy. Candidates are assessed by examination and practical coursework.
NCTJ-accredited courses are delivered by universities and colleges across the UK, as well as by the NCTJ itself through its distance-learning programme. Employers across UK national, regional, and digital newsrooms regularly specify NCTJ qualifications in job descriptions for sub-editing roles.
