15% of full-time UK undergraduates report the highest levels of life satisfaction, against 27% of the general UK population — and while student wellbeing has recovered to roughly where it stood a decade ago, it remains well below the population it is drawn from (Student Academic Experience Survey 2026, HEPI and Advance HE, published June 2026, 10,065 respondents).
Two things need saying before the numbers. There is no national dataset that isolates dissertation stress specifically — nobody surveys final-year students about their dissertation and reports it as a sector statistic. What exists is a large, well-established annual survey of undergraduate wellbeing and workload, and it is the right evidence to use provided you describe it accurately. Every figure below is from that survey unless attributed otherwise.
The wellbeing figures, with the population comparator
The survey has used the four Office for National Statistics personal wellbeing questions since 2014, each scored 0 to 10. The figures show the proportion giving the most positive answers: 9 or 10 out of 10 for satisfaction, worthwhile and happiness, and 0 or 1 out of 10 for anxiety, where a low score is the positive result.
| Year | Life satisfaction 9-10 | Life worthwhile 9-10 | Happiness 9-10 | Low anxiety 0-1 |
|---|---|---|---|---|
| 2026 students | 15% | 20% | 20% | 15% |
| 2025 students | 15% | 18% | 17% | 14% |
| 2025 general population (ONS) | 27% | 34% | 36% | 35% |
| 2024 students | 13% | 18% | 18% | 15% |
| 2023 students | 13% | 17% | 17% | 16% |
| 2022 students | 12% | 16% | 16% | 14% |
| 2021 students (pandemic low) | 6% | 12% | 11% | 13% |
| 2020 students | 11% | 15% | 14% | 18% |

The shape is a steep pandemic trough in 2021, then five years of gradual recovery that gained pace in 2026, with worthwhile and happiness both up and satisfaction flat. And a persistent gap: on every measure, undergraduates report worse wellbeing than the general population, most starkly on anxiety, where 15% of students report the lowest anxiety scores against 35% of the population.
The caveat the report makes itself
This is the detail to include if you quote the comparison. The survey’s authors note that although both studies use the same question wording, readers “should be slightly wary of directly comparing different studies among different populations”. Two separate surveys with different samples, methods and fieldwork periods are not a controlled comparison, and the student population differs from the general population in age alone in ways that affect these measures.
Quote the gap, attribute both sources, and carry the caveat. A marker will notice whether you did.
What the survey actually is
The Student Academic Experience Survey is run annually by the Higher Education Policy Institute with Advance HE. The 2026 edition, by Jonathan Neves, Rose Stephenson and Charlotte Armstrong, analysed 10,065 responses from full-time undergraduates at UK institutions, with online fieldwork conducted independently by Savanta between 6 January and 7 April 2026.
Population scope matters when you cite it: these are full-time undergraduates. The figures do not describe part-time students, and they do not describe postgraduates. Applying them to the whole student body misstates what was measured.
The workload figures — the most dissertation-relevant data there is
If you want evidence for why final-year students are under pressure, this is stronger than any wellbeing percentage, because it measures hours rather than feelings.
- 65% of full-time undergraduates are in paid employment during term time — described in the report as “still extremely high”, and now the majority experience rather than the exception.
- Students who work carry an average combined study and employment workload of 44.2 hours a week — almost identical to 2025’s 44.3 hours, and down from 50.1 hours in 2024.
- The average full-time job in the UK is 36.6 hours (ONS, as cited in the report). Working students are therefore carrying around eight hours a week more than a full-time worker.
- Counter-intuitively, students in paid employment also spend more time on average in independent study than those who do not work. The report is careful to say it is unclear whether this reflects a positive choice, a feeling of necessity, or both.
A dissertation is added on top of that, and it is the single largest independent-study commitment most undergraduates ever take on — typically several thousand words with no weekly deadline structure, in a term where two thirds of students are also working. The word budget itself varies sharply by department, as our survey of undergraduate dissertation word counts found.
How many students think about leaving?
22% of full-time undergraduates said they had considered leaving their course in 2026 — the lowest figure in recent years. 76% had not thought about making a change, and 2% were unsure or unable to say.
Read that alongside the wellbeing recovery rather than against it. The 2026 survey is, on most measures, a more positive picture than any in the past decade: perceptions of value for money reached 45%, up from 37% in 2025 and the highest in more than ten years. Student experience improving and student wellbeing remaining below the general population are both true at once, and a good statistics chapter says so.
What the data does not tell you
Four limitations worth stating explicitly if you cite any of this.
No dissertation-specific measure exists. Nothing in this survey isolates the dissertation from the rest of final year, so you cannot say “X% of students find their dissertation stressful” from it. Anyone who quotes such a figure should be asked for the instrument that produced it.
These are self-reports of general wellbeing, not clinical measures. The ONS four are subjective wellbeing questions, not diagnostic instruments, and they do not measure the prevalence of mental health conditions.
The wellbeing figures report only the extremes. They show the proportion giving the top two scores out of eleven, which is a deliberately demanding threshold; they are not a “percentage of happy students”.
Cross-survey comparisons are fragile. Different populations, different fieldwork windows, different modes. Keep each source’s figures inside their own sentence.
If you are reading this because of your own dissertation
The statistics say your experience is common. They do not say you should absorb it alone, and three routes exist that students consistently underuse.
Your university’s student support or wellbeing service is free, confidential, staffed by people who deal with exactly this every summer, and separate from your academic department. Your GP is the route for anything that has gone beyond ordinary deadline pressure. And extenuating circumstances procedures exist precisely for illness, bereavement and crisis — every UK institution has one, it is a formal process with evidence requirements and deadlines, and students routinely discover it too late to use. Read yours now rather than in the week you need it.
Tell your supervisor if you are struggling. Supervisors have seen it before, they cannot help with a problem they do not know about, and a student who says “I am three weeks behind” in June is in a far better position than one who says nothing until August.
How to cite these figures
Attribute to Neves, Stephenson and Armstrong, Student Academic Experience Survey 2026, Higher Education Policy Institute and Advance HE, published June 2026, with fieldwork by Savanta between 6 January and 7 April 2026 among 10,065 full-time UK undergraduates. Name the population in the sentence. Attribute the general-population comparators to the ONS and carry the report’s own warning about comparing different studies.
For adjacent figures, degree outcomes are covered in our roundup of degree classification statistics and AI use in our student AI use survey data — both drawn from different surveys with different populations, so keep them in separate sentences.
Where the pressure is specifically that the writing will not start, that is a mechanical problem with a mechanical fix rather than a character flaw. Tesify structures your dissertation chapter by chapter so the work becomes a task list instead of a fog, with every word still written by you — and our comparison of AI tools for dissertation writing covers what else is worth using. If you are being tempted by services that promise to write it for you, read our guide to what is legitimate and what is criminal first.
Frequently asked questions
What percentage of UK students find their dissertation stressful?
No published UK dataset measures this. Surveys measure general undergraduate wellbeing rather than dissertation-specific stress, so any percentage you see quoted for the dissertation itself should be traced to its instrument before you cite it.
How does student wellbeing compare with the general population?
It is lower on every measure. In the most recent comparison, 15% of students reported the highest life satisfaction against 27% of the general population, and 15% reported the lowest anxiety against 35%. The survey’s authors caution against treating this as a direct comparison because the studies and populations differ.
Is student wellbeing getting better or worse?
Better. Wellbeing bottomed out in 2021 and has recovered steadily since, with clear improvement in 2026 on the worthwhile and happiness measures, returning to around the levels last seen a decade ago.
How many hours a week do UK students actually work?
Among students in paid employment, the average combined study and employment workload was 44.2 hours a week in 2026, against an ONS-measured UK full-time job average of 36.6 hours. 65% of full-time undergraduates are in paid employment during term time.
How many students consider dropping out?
22% of full-time undergraduates said they had considered leaving their course in 2026, the lowest figure in recent years, with 76% saying they had not.
What is the Student Academic Experience Survey?
An annual survey of full-time UK undergraduates run by HEPI with Advance HE, in its twentieth year. The 2026 edition analysed 10,065 responses, with fieldwork by Savanta between January and April 2026.
Do these figures cover postgraduate students?
No. The sample is full-time undergraduates. Quoting these figures for postgraduates, or for the student body as a whole, misstates the population that was surveyed.
Can I use dissertation stress as an extenuating circumstance?
Ordinary deadline pressure is not usually grounds, because it affects everyone; illness, including mental illness, bereavement and personal crisis generally are. Every institution’s policy differs, most require evidence and have a deadline, and you should read yours before you need it.
Where do I get help if I am struggling right now?
Your university’s student support or wellbeing service, which is free and confidential; your GP for anything beyond ordinary stress; and your students’ union, which usually offers independent academic advice. Tell your supervisor too — they cannot help with something they have not been told.
Is it normal to feel this way about a dissertation?
The published data on workload and wellbeing suggests substantial pressure is the common experience rather than the exception. That is a reason to use the support that exists, not a reason to accept feeling terrible for six months.
