Aston University caps an MPhil or PhD thesis at 80,000 words (50,000 for an MD, 30,000 for an MSc/MA by Research), requires two independent examiners — one internal, one external — appointed under strict conflict-of-interest rules, sets the viva between three weeks and three months after submission, and gives the examiners nine possible outcomes on a doctoral submission, from an outright pass to no degree at all. This piece works through Aston’s own two regulatory documents directly.
Which documents actually govern an Aston doctoral thesis?
Two separate documents do the work most candidates expect one to do. General Regulations for Degrees by Research and Thesis (AU-REC-26-6684-A, 2026-27) governs supervision, examination, the viva and every outcome available to the examiners. General Regulations for the Presentation of Theses (AU-REC-26-6682-A, 2026-27, which replaced AU-GSMC-22-5493-B from September 2026) governs the physical and structural requirements: word count, abstract length, figure numbering, and the order of preliminary pages. A thesis that satisfies one and not the other is not ready for submission.
What is the actual word limit for an Aston PhD thesis?
Per Regulation 2.9.3 of the Presentation of Theses document: “MPhil or doctoral theses (apart from MD) should not normally exceed 80,000 words in length. Theses for professional doctorates (e.g. DBA, DOptom) may be shorter than for a traditional PhD.” An MD thesis is capped at 50,000 words (2.9.2) and an MSc/MA by Research thesis at 30,000 (2.9.1). Appendices, references and bibliographies never count toward the limit; footnotes are excluded too (2.9.4) — the 2026-27 edition dropped the earlier exception that counted footnotes in law and literature theses. Regulation 2.9.5 is blunt about the consequence: theses that exceed the limit “will not normally be accepted for examination,” and a student who anticipates exceeding it is told to raise it with their supervisor before submission, not after. The abstract itself is capped separately, at 300 words (3.3.3), with up to ten keywords for the British Library’s EThOS service listed at the foot of the abstract page (3.3.4).
How long do I actually have to submit, and can that be extended?
Regulation 14.1 sets normal time limits from the student’s research start date. A full-time PhD or professional doctorate student may submit no earlier than two years in, with a maximum of three years; a full-time MPhil student has the same earliest date and a maximum of two years; a full-time MD student’s earliest date and maximum both sit at two years. Part-time doctoral and professional doctorate students may submit no earlier than four years in, with a maximum of six years. A student who cannot meet the deadline can apply in advance — at least one month before the thesis is due — for an extension, backed by a timetable and a supporting statement from their supervisor (14.2b); the Associate Dean Research and Enterprise can normally grant up to one year beyond the maximum time limit for a doctoral or MPhil student (14.2d), and up to three months for an MSc/MA by Research student (14.2c).
Who has to be on the supervisory team, and who can examine the thesis?
Every research student is supervised by a Supervisor who is a member of Academic Staff (Regulation 6). A DBA candidate is additionally assigned a Process Supervisor for the taught element until the full supervisory team is appointed. Where the Supervisor is a Research or Teaching Fellow rather than permanent staff, an Associate Supervisor must be appointed alongside them, and a first-time doctoral supervisor is required to be supported by a more experienced Associate Supervisor. No one may be Supervisor to more than six research students at once without the Associate Dean’s agreement (6.1f), and at least one member of the supervisory team must be “engaged in excellent research” (6.1e).
At examination, Regulation 16.1 requires one Internal Examiner and one External Examiner, both demonstrably research-active, both experienced examiners (normally three or more previous doctoral examinations between the pair). The Internal Examiner cannot be the student’s Supervisor, Associate Supervisor, or otherwise connected to the supervision. Former Aston staff or students cannot be appointed External Examiner within five years of leaving. Neither examiner can have had substantial co-authoring or collaborative involvement with the student’s work, and an External Examiner cannot have collaborated with the Internal Examiner or the supervisory team in the five years before the viva. For an MD candidate, at least one examiner must be medically qualified. Underneath all of this sits Regulation 1.5’s conflict-of-interest test: a conflict exists wherever an independent observer could reasonably doubt a person’s ability to act impartially, whether or not any actual bias is proven.
How long after submission is the viva, and can it be held virtually?
Regulation 15.3 sets the window directly: “The viva voce examination shall normally be held at least three weeks and no more than three months after the submission of the thesis/portfolio.” A virtual viva is permitted under Regulation 18.1 only where the external examiner or candidate cannot reasonably travel — on grounds of prohibitive cost, timing difficulty, or restricted mobility — and specifically not merely because a candidate has left the university and does not want to return. Every party (candidate, examiners, and the Associate Dean Research and Enterprise) must agree to a virtual format, and a contingency plan for technical failure is required in advance.
What can the examiners actually recommend after a first viva?
Regulation 19.1 lists nine possible outcomes for a doctoral (MD/PhD/professional doctorate) submission — this is the section most candidates never read until the week of their own viva:
| Outcome | What it means |
|---|---|
| a — Award, no revisions | Final thesis submitted within one month of the viva |
| b — Award after revisions | Completed within three months (Regulation 20b) |
| c — Award after revisions | Completed within six months (Regulation 20b) |
| d — Resubmit and re-examine | Within one year, for the same doctoral award |
| e — MPhil instead | Awarded directly (PhD submissions only) |
| f — MPhil after revisions | Within three or six months (PhD submissions only) |
| g — Resubmit for MPhil | Within one year (PhD submissions only) |
| h — No degree | The submission fails outright |
| i — Referred to Master’s | Professional doctorate only, where a linked Master’s exists |
Two procedural rules bind the timing of a revisions outcome: the examiners must give the student written details of exactly what is required within two weeks of the viva (Regulation 20a), and the student then has three or six months from receiving that notification to complete the revisions, at the examiners’ discretion (20b). Where major or extensive defects require a full resubmission and re-examination, Regulation 21a sets a one-year limit from the date of the viva, running for both full-time and part-time students alike.
What happens on a resubmission, and can a failed PhD still become an MPhil?
Regulation 23.1 governs the outcomes available on a resubmitted doctoral thesis: award with no further revisions (final thesis due within one month), award after a further three or six months of revisions, the degree of MPhil instead (PhD resubmissions only), MPhil after further revisions, a failed professional-doctorate thesis referred to the relevant Master’s board where a linked Master’s exists, or no degree at all. What a resubmission cannot do is convert an MPhil resubmission back up into a PhD (23.d) — the ceiling on a second attempt is fixed by what was originally submitted for. The examiners should normally reach their decision within three months of the resubmission (23.c), and the resubmitted thesis must normally go back to the same two examiners unless there is a sound case for replacing one (Regulation 22a).
Does Aston’s own regulation say anything about using AI in the thesis?
Not this document. The General Regulations for Degrees by Research and Thesis (2026-27) opened for this piece contain no clause on generative AI disclosure or use — unlike some other UK universities’ presentation-of-theses policies, which now carry a dedicated AI-disclosure requirement. That does not mean Aston has no position: a university’s academic integrity or academic conduct policy is typically the document that carries an AI-use rule, and it sits outside the two regulations covered here. Check your own supervisor and the university’s academic integrity pages directly rather than assume either way. Tesify’s own drafting and editing workflow is built to sit inside whichever disclosure rule your own institution sets, rather than around it — worth checking against your supervisor’s expectations before you use any AI tool on chapter drafts.
How does Aston compare with the other institution-specific piece on this site?
The University of Manchester’s Presentation of Theses Policy, covered in a companion piece on this site, sets its own word limit and preliminary-page requirements, including a Generative AI Disclosure page that Aston’s regulations do not carry. Reading both if you are choosing between offers, or simply checking a co-supervision or cotutelle arrangement between the two institutions, shows how differently two UK universities can regulate what looks, from outside, like the same doctorate — which is precisely the reason this site says only what it has opened, university by university, rather than stating a single UK-wide rule. For the sector-wide picture rather than one institution’s own rule, the site’s piece on what a professional doctorate actually is sets Aston’s DBA and other professional routes in context.
Frequently asked questions
Is the 80,000-word limit for the whole thesis or just the main text?
It covers the main text only. Appendices, references and bibliographies are excluded from the count entirely, and, under the 2026-27 edition, footnotes are excluded as well.
Can a DBA or other professional doctorate thesis be shorter than 80,000 words?
Yes — Regulation 2.9.3 explicitly allows professional doctorate theses (the regulation names DBA and DOptom as examples) to run shorter than a traditional PhD, without setting one fixed alternative figure.
How soon after I submit will my viva actually happen?
Normally no sooner than three weeks and no later than three months after submission, per Regulation 15.3 — plan supervisor availability and examiner travel around that window rather than assuming a fixed date.
Can my own supervisor examine my thesis?
No. The Internal Examiner cannot be the student’s Supervisor, Associate Supervisor, or otherwise involved in the supervision, under Regulation 16.1d.
What is the difference between the three-month and six-month revisions outcomes?
Both are full doctoral awards conditional on completing corrections; the examiners set which timescale applies (Regulation 19.1b/c) based on the scale of the revisions required, and the student’s three-or-six-month clock starts from formal notification, not from the viva date itself.
If I am asked to resubmit, do I get the same examiners again?
Normally yes — Regulation 22a requires the resubmitted thesis to go back to the originally appointed examiners unless the university is satisfied there is a sound case to replace one of them.
Can a failed PhD thesis still result in a degree?
Sometimes. The examiners can recommend the award of MPhil instead of PhD, with or without further revisions (Regulation 19.1e/f), or refer an unsuccessful professional doctorate submission to a linked Master’s board where one exists (19.1i) — but they cannot recommend a doctoral award to a student who did not submit for it.
Is a virtual viva available if I have simply moved abroad after submission?
Not on that basis alone — Regulation 18.1 specifically states that a virtual viva should not normally be offered solely because the student has left the university and does not want to return for the examination.
How long does a full-time PhD student actually have before submission is due?
Normally a minimum of two years and a maximum of three, calculated from the research start date (Regulation 14.1) — with up to a further year available by an advance extension application backed by a supervisor’s supporting statement (14.2).
Does a part-time doctoral student get proportionally longer?
Yes — a part-time PhD or professional doctorate student’s earliest submission date is four years in, with a six-year maximum, roughly double the full-time figures rather than an exact multiple.
Where do I check whether a newer edition of these regulations has replaced the one this article used?
Aston’s general regulations page lists the current edition of both documents by reference number and academic year; this piece cites AU-REC-26-6684-A (2026-27) for examination and supervision, and AU-REC-26-6682-A (2026-27) for presentation and word limits — confirm the reference number matches the current version before relying on either for your own submission.
