Harvard referencing: the complete UK guide
In-text citations, reference list formats for every source type you are likely to use, and the mistakes that cost marks most often.
Harvard is the most common referencing style in UK higher education and the least standardised. There is no governing body and no single correct version, which is why your friend on another course has different rules and both of you are right.
Use your department guide first. Where it is silent, the conventions below are the common UK form.
How the system works
Two halves that must always match.
In the text
Recent work suggests the effect is smaller than previously assumed (Ahmed, 2024).
In the reference list
Ahmed, S. (2024) Reassessing intervention effects in adolescent health. 2nd edn. Manchester: Northgate Academic.
Every in-text citation needs a reference list entry, and every entry needs at least one citation. A mismatch is the single most common referencing error and one of the easiest for a marker to spot.
In-text citations
| Situation | Format |
|---|---|
| One author | (Ahmed, 2024) |
| Two authors | (Ahmed and Brown, 2024) |
| Three or more | (Ahmed et al., 2024) |
| Author named in your sentence | Ahmed (2024) argues that... |
| Direct quotation | (Ahmed, 2024, p. 87) |
| Page range | (Ahmed, 2024, pp. 87–89) |
| Two sources at once | (Ahmed, 2024; Brown, 2023) |
| Same author, same year | (Ahmed, 2024a; Ahmed, 2024b) |
| Organisation as author | (NHS England, 2025) |
| No date given | (Ahmed, no date) |
| Cited in another source | Brown (2019, cited in Ahmed, 2024) |
Page numbers are required for direct quotations. Most UK guides also expect them when you paraphrase a specific passage, which is more often than students assume.

Check whether your department wants teaching material referenced at all. Some prohibit citing lecture slides and expect you to find the underlying source instead.

Law students should use OSCOLA rather than Harvard. OurOSCOLA guide covers it.
Ordering the reference list
- Alphabetical by author surname, with no numbering and no bullet points
- Same author, multiple works: earliest year first
- Same author, same year: add a, b, c to the year and order by title
- Single-author works before the same author's co-authored works
- Organisations alphabetised by the first significant word, ignoring The
Use a hanging indent so second and subsequent lines sit further in than the first. Word does this under Paragraph, Special, Hanging.
Six errors that cost marks
| Error | Fix |
|---|---|
| A citation with no matching reference | Check every one before submitting. This is the error markers look for first. |
| Italics on the wrong element | Italicise the larger container: the book, or the journal, never the article title. |
| Missing page numbers on quotations | Always required for direct quotation. |
| Inconsistent punctuation between entries | Pick one pattern and apply it throughout, even if it is not your guide's exact pattern. |
| Generator output pasted unchecked | Reference generators get capitalisation, edition and publisher wrong constantly. Read every entry. |
| URL with no access date | Web sources need the date you last viewed them. |
A ten-minute check before you submit
- Read the reference list on its own, backwards. Out of order you notice formatting rather than content.
- Search the document for every open bracket and confirm each citation has an entry.
- Scan the list for anything you never actually cited, and remove it.
- Confirm the alphabetical order is genuinely correct, which generators often get wrong on organisations.
- Check that italics fall on the same element in every entry.
Referencing is the most avoidable cause of lost marks in UK universities, because it is the only part of your work that can be made completely correct with a checklist rather than an argument.

Frequently asked questions
Harvard is an author-date system. You cite the author surname and year in brackets inside your text, then list every source alphabetically in a reference list at the end. It is the most widely used style in UK universities.
Author or organisation, year in brackets, title in italics, then "Available at:" the URL, then "(Accessed: day month year)". Where no author is named, use the organisation. Where no date is given, write (no date) rather than guessing.
No, and this is the source of most confusion. Harvard is a family of styles rather than a single standard, so punctuation and capitalisation vary between universities. Always use your own department guide in preference to any general reference, including this one.
Cite the first author followed by et al. in your text, for example (Ahmed et al., 2024). In the reference list, most UK Harvard variants require all authors listed in full. Check your department guide, because some cap the list at six.
A reference list contains only the sources you cited in the text. A bibliography also includes background reading you consulted but did not cite. Most UK courses want a reference list, so do not add uncited sources unless you are asked to.
