How To Reference In APA 7th Edition: UK Guide 2026-2027

Half the APA advice online is still quietly teaching the 6th edition — and UK markers can tell.

This guide shows you exactly how to reference in APA 7th edition: in-text citations, the et al. rule, reference list formats for every source type, DOIs, and the 6th-to-7th changes that still catch students out. Written by Projectsdeal’s PhD-qualified UK team — 115,000+ orders since 2001 — with copy-ready examples for psychology, education, health and business.

APA 7th Edition: What It Is and Who Uses It in the UK

APA style — from the American Psychological Association’s Publication Manual, 7th edition (2019) — is the most tightly specified referencing system in academia, and in the UK it is the working standard for psychology (where BPS-accredited degrees use it almost universally), education, sport and exercise science, health sciences, and a growing number of business schools. Unlike “Harvard”, which is really a family of institutional variants, APA is centrally defined: one manual, one answer to every formatting question. That precision is why departments love it — and why markers spot deviations instantly.

The system has two moving parts that must mirror each other perfectly: in-text citations (brief author–date markers inside your sentences) and the reference list (full retrieval details for every cited source, and only cited sources — APA has no bibliography of “background reading”). This guide covers both, plus the 6th-to-7th edition changes that still contaminate half the advice online, the formats for every source type UK students actually cite, and the error patterns we see across thousands of psychology and education scripts. Where useful it contrasts APA with its author–date cousin — see our guides to Harvard referencing and citing in Harvard style if your other modules use that family.

In-Text Citations: The Complete Rule Set

Every claim drawn from a source gets an author–date marker in one of two grammatical forms. Parenthetical: “Anxiety and performance follow an inverted-U relationship (Yerkes & Dodson, 1908).” Narrative: “Yerkes and Dodson (1908) demonstrated an inverted-U relationship.” Note the switch: ampersand inside brackets, the word “and” in running text — the single most common slip in student work.

Author-number rules are mercifully simple in the 7th edition:

The et al. rule deserves emphasis because it changed in the 7th edition: three or more authors shorten to “First Author et al.” from the first citation, not the third. Write it exactly as “et al.” — full stop after “al”, none after “et”, never “et. al.”. If two different sources shorten to the same form (Smith et al., 2020 twice), add as many co-author names as needed to tell them apart.

Direct quotations always carry a locator: (Field, 2018, p. 23) for one page, pp. 23–24 for a range, and paragraph numbers or section headings for unpaginated web sources (NHS, 2023, para. 4). Quotations of 40+ words become indented block quotes without quotation marks, with the citation after the final punctuation. Multiple sources in one bracket are alphabetised and semicolon-separated: (Bandura, 1977; Bruner, 1960; Vygotsky, 1978). Secondary citations — sources you read about but did not read — use “as cited in”: Piaget’s theory (1936, as cited in Smith, 2020), with only Smith entering your reference list; use them sparingly and hunt down originals for anything load-bearing. Same author, same year? Letter the works (Twenge, 2020a, 2020b) in both text and list. These mechanics feel fussy for a fortnight and then become automatic — and they are precisely what distinguishes a polished script when your marker is deciding between a 68 and a 72, a distinction that matters if you are chasing the habits in our guide to getting a first-class degree.

The Reference List: Formats for Every Source You Will Actually Cite

The list starts on a new page headed References (bold, centred), alphabetised by first author surname, double-spaced, with a hanging indent of 1.27 cm. Every entry answers four questions in fixed order: Who? (When?) What? Where? Titles of articles and chapters take sentence case (capitalise only the first word, the first word after a colon, and proper nouns); journal names take Title Case and italics. Here are the workhorse formats with real examples:

Journal article (the format you will use most):
Braun, V., & Clarke, V. (2006). Using thematic analysis in psychology. Qualitative Research in Psychology, 3(2), 77–101. https://doi.org/10.1191/1478088706qp063oa
Volume italicised with the journal name; issue number in roman type in brackets; DOI as a live https link. No DOI and read via a database? Simply end after the page range — APA 7 dropped database names and “Retrieved from” for stable sources.

Book:
Field, A. (2018). Discovering statistics using IBM SPSS statistics (5th ed.). SAGE.
No city, no country — publisher location was abolished in the 7th edition, so “London: SAGE” instantly reveals a recycled 6th-edition reference.

Chapter in an edited book:
Ashworth, P. (2015). Conceptual foundations of qualitative psychology. In J. A. Smith (Ed.), Qualitative psychology: A practical guide to research methods (3rd ed., pp. 4–24). SAGE.

Webpage by an organisation:
National Health Service. (2023, March 14). Overview: Depression in adults. NHS. https://www.nhs.uk/mental-health/conditions/depression-in-adults/
Add “Retrieved January 12, 2026, from” before the URL only when content is designed to change, such as live dashboards.

White Rose eTheses Online. — a format you will meet often if postgraduate study is on your horizon; our guide to getting a PhD in the UK explains the territory those theses come from.

Big author teams: list up to 20 authors in full. For 21 or more, give the first 19, an ellipsis, then the final author — no ampersand. (The 6th edition’s “seven then et al.” rule is dead.)

APA 6 vs APA 7: The Changes UK Markers Actually Check

Most referencing errors in current UK scripts are not carelessness — they are fossils of the 6th edition, absorbed from outdated guides, old lecture slides and second-hand textbooks. This table is your de-fossilisation checklist:

If your current draft says “Retrieved from”, names a city before a publisher, or lists five authors in an in-text citation, you now know exactly what happened — and exactly what to fix.

Beyond Citations: The APA Rules That Frame Your Whole Paper

APA is a manuscript style, not just a citation style, and UK psychology departments increasingly mark against the full package. Headings run through five defined levels — Level 1 centred bold, Level 2 flush-left bold, Level 3 flush-left bold italic — and using them consistently makes lab reports self-organising. Statistics have fixed presentation: italicise statistical symbols (M, SD, t, p, d), give exact p values to three decimals except p < .001, omit the leading zero for values that cannot exceed 1 (p = .03, r = .47), and report effect sizes alongside significance: t(58) = 2.41, p = .019, d = 0.62. Bias-free language is a chapter of the manual in its own right: person-first or identity-first language used thoughtfully, specific ages rather than “the elderly”, singular “they” where gender is unknown or irrelevant. Numbers are words below 10 and numerals from 10 upwards, with exceptions for units, statistics and the start of sentences. None of this is decoration — in BPS-accredited programmes these conventions are part of the assessed skill of scientific communication, and they transfer directly into the report and dissertation formats covered across our writing guides, from introductions to full case studies.

The Ten Most Common APA 7 Errors in UK Student Work

Joint honours students juggling systems should keep our other style guides bookmarked: OSCOLA for law, Vancouver for medicine and nursing, MHRA and Oxford footnote style for humanities, and MLA for literature modules. The styles disagree about punctuation; they agree completely about honesty.

Awkward Sources: The Formats Students Have to Hunt For

The manual’s core formats cover 90% of citations; the remaining 10% consume 90% of the referencing time. Here are the awkward cases UK students meet most, solved:

Lecture slides and course materials: cite what a reader can access. For slides on your VLE: Tutor, A. (2025). Week 4: Attachment theory [PowerPoint slides]. Moodle. https://vle.university.ac.uk — but if the audience of your work cannot access the VLE, treat spoken lecture content as a personal communication instead.

Personal communications — emails, interviews you conducted for coursework (not research data), conversations — are cited in text only and never enter the reference list: (P. Ncube, personal communication, February 3, 2026), because readers cannot retrieve them.

Psychological tests and measures: cite the supporting literature — Goldberg, D. P., & Williams, P. (1988). A user’s guide to the General Health Questionnaire. NFER-Nelson — not the questionnaire PDF you downloaded.

Datasets: Office for National Statistics. (2024). Annual population survey [Data set]. UK Data Service. https://doi.org/10.xxxx — datasets increasingly carry DOIs; use them.

YouTube videos and podcasts: the uploader is the author — TED. (2012, March 1). Susan Cain: The power of introverts [Video]. YouTube. https://youtube.com/… — and for podcasts, the host: Shepherd, M. (Host). (2023–present). PsychCrunch [Audio podcast]. British Psychological Society.

Social media: up to the first 20 words of the post stand as the title, with the platform and [Tweet], [Post] or similar bracketed description. Ephemeral content (Stories) needs a retrieval date.

UK legislation and cases in an APA paper: APA’s legal formats are US-centric, so most UK departments direct you to cite British statutes by short title and year — Mental Capacity Act 2005 — in text with a conventional entry in the list; if your work is law-heavy, your department may prefer the dedicated legal conventions covered in our OSCOLA guide. Ask before inventing a hybrid.

Translated and republished classics: credit both dates — Freud, S. (1953). The interpretation of dreams (J. Strachey, Trans.). Hogarth Press. (Original work published 1900) — cited in text as (Freud, 1900/1953).

Worked Example: A Cited Paragraph and Its Reference Entries

Here is the whole system operating in four sentences of a psychology essay, exactly as a marker would want to see it:

Working memory capacity is sharply limited, with classic estimates of around four chunks in adults (Cowan, 2001). Baddeley and Hitch (1974) explained such limits through a multicomponent model in which a central executive coordinates domain-specific stores, and the model still anchors contemporary research (Baddeley, 2012). Training studies, however, offer little evidence that capacity itself can be expanded: a meta-analysis of 87 comparisons found near-transfer only, with “no convincing evidence of generalisation” to untrained abilities (Melby-Lervåg et al., 2016, p. 512). The practical implication for educators is to reduce load rather than train capacity (Centre for Educational Neuroscience, n.d.).

Notice the machinery: a parenthetical citation for a paraphrased estimate; a narrative citation with “and” rather than an ampersand; an et al. citation with a page-numbered direct quote; and an organisational author with no date. Behind that paragraph, four reference entries would sit alphabetised — Baddeley (2012) as a journal article with DOI; Baddeley and Hitch (1974) as a chapter in an edited volume; Cowan (2001) and Melby-Lervåg et al. (2016) as articles; the Centre for Educational Neuroscience as a webpage. Four sentences, five sources, zero ambiguity about whose ideas are whose — that is the entire point of the apparatus, and it is achievable in every paragraph you write once the patterns are automatic.

Why Markers Care This Much (and What It Is Really Testing)

It is fair to ask why a psychology degree spends marks on comma placement. The honest answer is that APA referencing is a proxy for three professional skills at once. First, evidential honesty: the citation trail lets any reader walk back from your claim to its source, which is the basic contract of scientific writing — and the reason sloppy referencing shades into the misconduct territory mapped in our plagiarism guide. Second, precision under rules: clinical notes, ethics applications and journal submissions all demand exact compliance with externally imposed formats, and APA is the training ground. Third, reader care: a consistent style removes friction so attention goes to the argument. Departments that mark referencing strictly are not being pedantic; they are assessing whether you can be trusted with the discipline’s paperwork — a skill that, unlike most module content, you will use every working week for decades.

Formatting the Student Paper Around It

APA 7 finally distinguishes student papers from journal manuscripts, and UK departments largely follow the student conventions: a title page with title in bold (Title Case), your candidate details as required locally, no running head and no abstract unless asked; an accessible font used consistently (11-point Calibri, 11-point Arial and 12-point Times New Roman are all sanctioned); double spacing throughout including the reference list; 2.54 cm margins; and page numbers top right. Tables and figures are numbered in bold (Table 1) with an italic title beneath the number, and every table or figure must be called out in the text before it appears. Departments overlay local rules — anonymous marking codes, line-spacing exceptions, appendix conventions — and local rules always win; the manual itself says as much.

A Practical Workflow — and Expert Help When You Need It

Referencing goes wrong at 11pm on deadline day and almost never earlier, so move it upstream. Build the habit in three layers: capture, cite, audit. Capture full source details the moment you read anything (Zotero and Mendeley both ship APA 7 output, though both need proofreading — capitalisation and DOI formats especially); cite as you draft rather than “adding references later”; and finish with a fifteen-minute audit pass — text-to-list match, sentence case, et al. forms, DOIs live. Students who adopt this workflow simply stop losing referencing marks, permanently.

And when the stakes or the scale outgrow DIY — a 200-entry dissertation list, a resubmission with referencing flagged, a switch of styles mid-degree — Projectsdeal has been the UK’s quiet fix since 2001.

What UK Students Say

Frequently Asked Questions

1. What is APA 7th edition referencing?
APA 7th edition is the current citation style of the American Psychological Association, published in 2019 and adopted by most UK psychology, education and health departments. It pairs brief author-date citations in the text with a full alphabetical reference list, and sets detailed rules for formatting, headings, bias-free language and statistics reporting as well as citations.

2. How do I cite in-text in APA 7?
Parenthetical: (Field, 2018). Narrative: Field (2018) argues... Two authors use an ampersand in brackets - (Kahneman & Tversky, 1979) - but 'and' in the sentence. Three or more authors shorten to et al. from the very first citation: (Braun et al., 2019). Direct quotations add a locator: (Field, 2018, p. 23).

3. What is the et al. rule in APA 7th edition?
Any source with three or more authors is cited as First Author et al. from the first in-text citation onwards - unlike APA 6, which listed up to five authors first time. In the reference list, spell out up to 20 authors; for 21 or more, list the first 19, insert an ellipsis, then give the final author with no ampersand.

4. How do I reference a journal article in APA 7?
Author, A. A., & Author, B. B. (Year). Title of article in sentence case. Journal Name in Title Case and Italics, Volume(Issue), page range. https://doi.org/xxxx. Example: Braun, V., & Clarke, V. (2006). Using thematic analysis in psychology. Qualitative Research in Psychology, 3(2), 77-101. https://doi.org/10.1191/1478088706qp063oa

5. How do I reference a book in APA 7?
Author, A. A. (Year). Title of book in italics and sentence case (edition if not first). Publisher. Example: Field, A. (2018). Discovering statistics using IBM SPSS statistics (5th ed.). SAGE. APA 7 dropped the publisher's location, so 'London: SAGE' is now an instant giveaway of outdated 6th-edition habits.

6. How do I reference a website in APA 7?
Author or organisation. (Year, Month Day). Title of page in italics. Site Name. URL. Example: National Health Service. (2023, March 14). Overview: Depression in adults. NHS. https://www.nhs.uk/mental-health/conditions/depression-in-adults/ Use 'Retrieved [date], from URL' only when the content is designed to change, such as a live statistics dashboard.

7. Do I need DOIs in APA 7th edition?
Yes, whenever one exists - formatted as a live link, https://doi.org/10.xxxx, not as 'doi:10.xxxx' or 'Retrieved from'. If a journal article has no DOI and was read in an academic database, end the reference after the page range; no database name or URL is needed.

8. How do I cite a source with no author or no date in APA 7?
No author: move the title into the author position - ('Title of article', 2020) in text, using double quotation marks around article titles and italics for standalone works. No date: use n.d. - (British Psychological Society, n.d.). Both are common with organisational web sources.

9. How do I cite a secondary source (as cited in) in APA 7?
Name the original source in your text, then cite the source you actually read: Piaget's stage theory (1936, as cited in Smith, 2020) - and include only Smith (2020) in the reference list. APA advises using secondary citations sparingly; find the original wherever practicable.

10. What changed between APA 6th and 7th edition?
The changes UK markers check: et al. from first citation for 3+ authors; publisher locations abolished; up to 20 authors in references (was 7); DOIs as https links; 'Retrieved from' dropped for stable URLs; singular 'they' endorsed; running heads no longer required on student papers; and expanded formats for social media, podcasts and datasets.

11. Which UK subjects and universities use APA 7?
Psychology departments across the UK use it almost universally, following BPS accreditation norms; it is also standard in education, sport science, health sciences and many business schools. Universities sometimes issue local guidance on fonts, headings or minor variations, so your module handbook always takes precedence over the generic manual.

12. Is APA the same as Harvard referencing?
They are cousins, not twins. Both are author-date systems, but APA fixes every detail centrally (punctuation, italics, DOIs, et al. rules) while 'Harvard' is a family of institution-specific variants. Details differ - Harvard styles often write (Smith and Jones, 2020) where APA requires (Smith & Jones, 2020), and reference list punctuation diverges throughout. Never mix them in one document.

13. How do I format an APA 7 reference list?
Start on a new page headed 'References' in bold, centred. Alphabetise by first author surname, double-space entries and apply a hanging indent of 1.27 cm (0.5 in). Order multiple works by the same author by year; same author and year take letter suffixes (2020a, 2020b) matched in the in-text citations.

14. How do I cite AI tools like ChatGPT in APA 7?
APA's interim guidance treats the AI company as author: OpenAI. (2025). ChatGPT (March 2025 version) [Large language model]. https://chat.openai.com - cited in text as (OpenAI, 2025). But check your UK university's AI policy first: many restrict or prohibit AI-generated content in assessed work regardless of citation, and correct referencing does not make prohibited use legitimate.

15. What are the most common APA 7 mistakes UK students make?
Writing et al. incorrectly (et al without the stop, or 'et. al.'); using 6th-edition habits like publisher locations and 'Retrieved from'; ampersand/and confusion between parenthetical and narrative citations; capitalising article titles in Title Case instead of sentence case; missing page numbers on direct quotes; and reference lists that do not match the in-text citations one-for-one.

16. Can Projectsdeal fix my APA referencing for me?
