Can a proofreader fix your grammar, or only point at it? The answer depends on which UK university you are enrolled at, and the differences are larger than most students expect. Leeds lets a third-party proofreader correct spelling, grammar and syntax in a research thesis; Aberdeen and Leicester allow the same errors to be identified but not changed; Swansea does not permit professional proofreading for taught degrees at all.

Getting this wrong is not a formatting slip: several policies treat proofreading that goes beyond the permitted scope as academic misconduct. This guide to academic proofreading rules reads seven current UK policies, extracts what each one allows and forbids, and condenses them into one table you can give to a proofreader before work starts.
What is academic proofreading? In UK university regulations, proofreading is the systematic checking and identification of errors in spelling, punctuation, grammar, sentence construction, formatting and layout in a finished text, including the bibliography. The University of Leeds policy uses almost exactly this wording and then defines editing as any material amendment that exceeds it, in particular any alteration that changes, corrects, expands or condenses the academic content. The line between the two is the line between permitted help and misconduct.
Why do universities set academic proofreading rules at all?
Because a thesis is assessed as the student’s own work. Leeds states the principle plainly: responsibility for all aspects of the thesis remains with the postgraduate researcher as its author. Edinburgh’s College of Arts, Humanities and Social Sciences guidance (May 2024) draws the consequence: students may engage a proofreader to suggest minor changes that improve the readability of written English, but engaging someone to make substantive changes or to produce content is editing, and the guidance classifies it as academic misconduct.
Oxford’s plagiarism guidance approaches the same line from the other side: students must acknowledge all assistance that contributed to their work, with an exception for the supervisor and for “ordinary proofreading”, while any guidance that leads to substantive changes of content or approach must be acknowledged.
Two further concerns run through the documents. Proofreading of early drafts can mask a need for writing support, which is why Leeds forbids third-party proofreading of progress-review and transfer submissions and Dundee limits research students to the final version of the thesis. And because a university cannot see what happened between student and proofreader, most academic proofreading rules require the student to keep the marked-up files as evidence.
Which academic proofreading rules did we compare?
All documents below were opened in October 2026; links are in the sources section.
| University | Document | Who it covers | Headline rule |
|---|---|---|---|
| Leeds | Postgraduate research proof-reading policy and guidance, version 4.0 (in effect 1 September 2023, updated June 2024) | Research degree theses | Permitted for the thesis before examination and for post-viva corrections; not for progress reviews; formal declaration required |
| Dundee | Guidance on proofreading of written submissions for assessment | All assessed work including theses | Research students may use proofreaders for the final thesis, not for draft chapters reviewed by supervisors |
| Edinburgh (CAHSS) | Proofreading of Student Assessments (Academic Services, May 2024) | Assessed work in the college | Minor issues may be corrected with tracked changes; major issues may only be commented on |
| Essex | University Policy and Guidance on Proofreading of Student Texts | Coursework up to PhD level | Two levels of intervention defined; consult the supervisor first; acknowledge the proofreader |
| Swansea | Proof Reading Policy | All students | Professional third-party proofreading not permitted for taught students unless approved, for example through Disabled Students’ Allowance; research students may use it and must inform supervisors |
| Aberdeen | Proof Reading Guidance for Students (approved September 2017) | All students | Third-party proofreading strongly discouraged; if used, it must be declared and errors may only be identified, not corrected |
| Leicester | Policy relating to proof-reading services | All students | Permitted if authorship is not compromised; students should declare it and check departmental rules |
Sheffield Hallam’s guidelines for taught students follow the Aberdeen and Leicester pattern: proofreading is allowed unless the module handbook says otherwise, the proofreader identifies and suggests, and may not make grammatical, syntactical or stylistic corrections directly.
📱 Request academic proofreading — You are told the reviewer’s field and degree before work starts, and a meeting is scheduled to confirm your university’s rules.
What can a proofreader change under academic proofreading rules?
The permitted zone is narrow and concerns language and presentation only. Where the academic proofreading rules disagree, the table shows the strictest and the most permissive positions.
| Task | Most permissive position | Strictest position | Typical condition |
|---|---|---|---|
| Spelling and typographical errors | Correct them (Leeds; Edinburgh for minor, localised items) | Identify and suggest only (Aberdeen, Leicester, Sheffield Hallam) | Tracked changes or comments so every change is visible |
| Punctuation | Correct (Leeds, Edinburgh) | Identify only (Aberdeen) | As above |
| Grammar and syntax | Correct (Leeds; Edinburgh when limited to single words) | Identify and suggest only (Aberdeen, Leicester, Sheffield Hallam) | Meaning must stay identical |
| Word usage | Correct, excluding specialist terminology (Leeds) | Not covered | Terminology remains the student’s responsibility |
| Inconsistent capitalisation, abbreviations, numbering of tables and figures | Correct (Leeds) | Highlight only (Aberdeen, Leicester) | Follow the faculty style guide |
| Formatting of page numbers, headers and footers | Correct (Leeds) | Must not touch document appearance (Edinburgh) | Check which rule applies to you |
| Presentation of in-text citations and bibliography entries | Correct inconsistencies (Leeds); amend a sample section as a model for the student (Essex) | Must not touch reference lists at all (Edinburgh) | Never add or remove references |
| Unclear, ambiguous or repetitive sentences | Identify and explain the problem (all policies) | Identify only, never rewrite (all policies) | The student rewrites |
| Labels of figures, charts and tables | Identify errors (Dundee, Leicester, Aberdeen) | Must not re-label (Leeds, Aberdeen, Leicester) | Point, do not fix |
What can a proofreader never change?
On the forbidden list the academic proofreading rules are almost unanimous. A proofreader must not:
- rewrite, add, condense or reorder sentences, paragraphs or sections, even to clarify meaning (Leeds, Essex, Edinburgh, Aberdeen, Leicester, Sheffield Hallam);
- alter the substance of ideas or arguments, or anything relating to the sequence of information or line of argument (Leeds, Edinburgh);
- add academic content, missing references or additional material (Leeds, Aberdeen, Dundee);
- check, correct or comment on facts, data, calculations, equations, formulae or computer code (Leeds, Dundee, Edinburgh, Aberdeen);
- translate any part of the work into English (Leeds, Dundee, Edinburgh, Sheffield Hallam);
- reduce the word count to meet a limit (Dundee, Edinburgh, Sheffield Hallam);
- change the referencing system, for example from Harvard to Vancouver (Dundee, Edinburgh);
- re-label diagrams, charts or figures (Leeds, Aberdeen, Leicester);
- make untracked changes (Edinburgh, Essex).
Essex adds a sensible escape valve: a proofreader who notices a factual or logical problem may advise the student to raise it with the supervisor, but may not fix it.
Where do academic proofreading rules differ most?
Four points decide what your proofreader may actually do.
- Correct versus identify. Leeds permits direct correction of language errors; Aberdeen, Leicester and Sheffield Hallam permit identification only, so the student makes every change. Edinburgh sits in between: minor, localised items may be corrected with tracked changes, while anything affecting whole sentences may only be commented on.
- Taught versus research degrees. Swansea bars professional proofreading for undergraduate and taught master’s students but allows it for research students. Leeds has a separate policy for taught assessments. A taught MSc dissertation and a PhD thesis can therefore fall under different rules at the same university.
- Stage of the work. Dundee and Leeds allow proofreading of the final thesis only, not of draft chapters that go to supervisors; Essex says text should normally go to a proofreader at completion stage and never as outlines or notes.
- Formatting and references. Leeds treats formatting consistency and reference presentation as proofreading; Edinburgh excludes document appearance and reference lists entirely.
Do academic proofreading rules require you to declare it?
Usually yes, and the form varies.
| University | Declaration requirement |
|---|---|
| Leeds | Mandatory statement on the declarations page: “The thesis was proof-read before submission by a third-party proof-reader. The PGR confirms that the third-party proof-reading undertaken was in accordance with the Postgraduate Researcher Proof-reading Policy.” |
| Aberdeen | Must be declared on submission of the work |
| Leicester | Students should declare that a proofreader has been used on submission |
| Edinburgh (CAHSS) | Students should declare the use of a proofreader, and must acknowledge generative AI if an online proofreading tool used it |
| Dundee | No formal declaration; acknowledgement in the final submission is described as a normal courtesy |
| Essex | Include the proofreader in the acknowledgements of a dissertation; state on the cover sheet of a term paper that it was proofread |
| Swansea | Research students must inform their supervisors when the thesis is submitted |
If your handbook is silent, declare anyway. An acknowledgement costs one sentence; an undeclared proofreader discovered later looks like concealment.
How do you brief a proofreader so the work stays compliant?
- Send the policy with the file, so the proofreader works to your university’s academic proofreading rules. Leeds and Dundee make this the student’s duty, and Sheffield Hallam makes the student responsible for the proofreader’s compliance.
- Agree the scope in writing: language and presentation only, with no changes to content, structure, references, figures or data. Essex recommends marking up a two- or three-page sample first so both sides see what the work involves.
- Insist on visibility. Leeds asks for comments rather than tracked changes and a PDF return; Edinburgh and Essex require tracked changes for any edit. Either way, nothing may change invisibly.
- Keep the version you sent and the version you received. Leeds, Edinburgh and Aberdeen may ask for them, and Aberdeen warns that failing to produce them can itself be penalised.
- Decide every change yourself. Essex calls this ownership of corrections: never “accept all”.
- Proofread last. Get the content approved by the supervisor first, then fix the language, otherwise the next round of supervisor comments undoes the proofreading.
What does this mean if you use a professional service?
A compliant service works inside these academic proofreading rules by design. At Mastermind PhD, academic proofreading changes language and formatting only, never content, argument or data; every edit is delivered as tracked changes so you can accept or reject it; you are told the reviewer’s field and degree before work starts, and a meeting is scheduled to confirm your university’s requirements; every file comes with a Turnitin report and an AI check. Payment is in two stages (80/20), and revisions are free until supervisor approval within 30% of the chapter.
Whatever provider you use, the test is the same: could you hand the marked-up file to your examiners and show that every change falls inside your university’s permitted list? If not, the proofreader went too far.

Frequently asked questions
Is proofreading a thesis allowed at UK universities?
At the universities compared here, yes for research theses, with conditions on scope, stage and declaration. The exceptions are taught degrees at Swansea, where professional third-party proofreading is not permitted unless specifically approved, and Aberdeen, which strongly discourages it for everyone. Always read your own handbook, because departments can add restrictions.
Can a proofreader correct my grammar directly?
At Leeds, yes, provided the change is visible and does not alter meaning. At Aberdeen, Leicester and Sheffield Hallam the proofreader may only identify the error and suggest a correction, and you make the change. Edinburgh allows direct correction only of minor, localised items such as a single word or a punctuation mark.
Does a friend or partner count as a third-party proofreader?
Yes. Leeds and Edinburgh define third parties as anyone other than the supervisory team, including fellow students, friends and family, paid or unpaid. The same scope limits and the same declaration apply.
What happens if the proofreader changed more than allowed?
You remain responsible. Leeds states that inadequacies in third-party proofreading will not be accepted in mitigation, Aberdeen says any deficiencies are the student’s responsibility, and Leicester, Sheffield Hallam and Edinburgh treat excessive intervention as a matter for an academic misconduct investigation. Keeping the before and after files is your main protection.
Do academic proofreading rules also apply to Grammarly and AI proofreading tools?
Increasingly, yes. Edinburgh’s guidance lists what an online proofreading tool must never do without acknowledgement, including rewriting text, changing tone or translating, and requires students to acknowledge generative AI functions. Birmingham’s [Doctoral School guidance](https://intranet.birmingham.ac.uk/student/libraries/research/thesis/genai-thesis-pgrs.aspx) applies the same proofreading limits to generative AI and requires a statement in the acknowledgements naming the tool and its remit.
