How to Write a Dissertation Conclusion: Step-by-Step UK Guide

The conclusion is the last thing your examiner reads before deciding on your mark. A strong conclusion pulls your whole dissertation together, shows that you have answered your research question, and leaves the reader convinced your work matters. A weak one – rushed, repetitive or vague – can undo much of the good work in earlier chapters.

This step-by-step guide shows you how to write a dissertation conclusion for a UK university: what it should include, how long it should be, how it differs from the discussion chapter, and the mistakes that cost students marks.

What Is a Dissertation Conclusion?

The dissertation conclusion is the final chapter of your dissertation. Its job is to answer your research question directly, summarise your key findings, explain what they mean, and show the contribution your research makes. It should also acknowledge the limitations of your study and suggest directions for future research.

Unlike the introduction, which opens questions, the conclusion closes them. It should feel like the natural end point of everything that came before.

How Long Should a Dissertation Conclusion Be?

Most UK dissertations allocate around 5–10% of the total word count to the conclusion. In practice that usually means:

Dissertation length	Typical conclusion length
10,000 words (undergraduate)	500–1,000 words
15,000–20,000 words (master’s)	1,000–2,000 words
80,000+ words (PhD)	Often a full chapter of several thousand words

These are guidelines, not rules. Always check your module handbook and ask your supervisor if you are unsure.

What to Include in a Dissertation Conclusion

A well-structured conclusion normally covers six elements:

1. A clear answer to the research question
2. A summary of the key findings
3. Your contribution to knowledge – what is new or useful about your work
4. Recommendations for practice, policy or professionals (where relevant)
5. Limitations of your study
6. Suggestions for future research

How to Write a Dissertation Conclusion: Step by Step

Step 1 – Restate Your Research Question and Aim

Open by briefly reminding the reader what your study set out to do. One or two sentences are enough. This frames the chapter and helps the examiner judge whether you have achieved your aim.

“This dissertation set out to examine how hybrid working affects employee engagement in UK financial services firms.”

Step 2 – Answer the Research Question Directly

This is the most important part of the conclusion, and the part students most often leave out. Give a clear, direct answer to your main research question. If you had several research questions or objectives, address each in turn. Avoid hedging so heavily that the reader cannot tell what you found.

Step 3 – Summarise Your Key Findings

Briefly summarise your most important findings and how they relate to one another. Do not repeat your results chapter or reintroduce statistics – focus on the big picture. Aim for synthesis: explain what your findings mean together, not just one by one.

Step 4 – Explain Your Contribution

Show the examiner why your research matters. Does it fill a gap in the literature, support or challenge an existing theory, apply a theory in a new context, or offer practical insight? Stating your contribution clearly is one of the strongest signals of a first-class dissertation.

Step 5 – Make Recommendations

In applied subjects such as business, education, nursing or social work, include practical recommendations based on your findings. Keep them specific and realistic, and make sure each one is supported by your evidence.

Step 6 – Acknowledge Limitations

Every study has limitations – a small sample, a single case study, a short timeframe, or limits on what data you could access. Acknowledging them honestly shows critical awareness. Briefly explain how each limitation may have affected your findings, without undermining your whole study.

Step 7 – Suggest Future Research

Finish by suggesting where future research could go next. Good suggestions often grow naturally from your limitations: for example, testing your findings with a larger sample, in another sector, or using a different methodology.

Step 8 – End With a Strong Closing Statement

Close with one or two sentences that reinforce the significance of your research. Avoid introducing new ideas – instead, leave the reader with a clear sense of why your work matters.

Dissertation Conclusion Example

Below is a short example conclusion for a fictional master’s dissertation in business management. A real conclusion would be longer, but this shows how each element fits together.

This dissertation set out to examine how hybrid working affects employee engagement in UK financial services firms. Drawing on a survey of 140 employees and interviews with 10 line managers, it found that hybrid working was associated with higher engagement overall, but only where employees had regular, structured contact with their manager. Where that contact was missing, engagement fell, particularly among newer staff.

These findings extend existing research by showing that the effect of hybrid working depends less on where people work and more on how they are managed. For practice, the study recommends that firms train managers to hold short, scheduled one-to-one check-ins and give new starters additional in-person time during their first months.

The study was limited to three firms and relied partly on self-reported data, so the findings may not apply across the wider sector. Future research could test these results with a larger, longitudinal sample. Overall, this dissertation shows that hybrid working can strengthen engagement – but only when organisations invest in the management practices that make it work.

Notice how the example restates the aim, answers the question, explains the contribution, gives practical recommendations, acknowledges limitations and suggests future research – all without introducing new data.

How to Structure Your Conclusion Paragraph by Paragraph

If you are not sure how to organise the chapter, this simple structure works for most undergraduate and master’s dissertations:

Paragraph 1: Restate the aim and give a direct answer to the main research question.
Paragraphs 2–3: Summarise the key findings for each objective and explain how they connect.
Paragraph 4: State your contribution to theory and practice, with recommendations.
Paragraph 5: Acknowledge limitations and suggest future research.
Final paragraph: A short closing statement on the significance of your work.

Dissertation Conclusion vs Discussion: What’s the Difference?

Many students blur these two chapters. In some disciplines they are combined, but where they are separate they do different jobs. You can read more in our guide on how to write a discussion chapter.

Feature	Discussion	Conclusion
Main purpose	Interprets findings in detail	Answers the research question and closes the study
Engagement with literature	Extensive – compares findings with other studies	Brief – focuses on your contribution
Level of detail	Detailed and analytical	Concise and big-picture
Limitations and future research	Sometimes introduced	Always summarised
Typical length	Often one of the longest chapters	Usually 5–10% of the word count

Common Dissertation Conclusion Mistakes

• Introducing new data or arguments – everything in the conclusion should come from earlier chapters.
• Not answering the research question – examiners look for this first.
• Copying sentences from the introduction or abstract – summarise in fresh words.
• Being too long or too short – a one-paragraph conclusion looks rushed; a five-page summary looks repetitive.
• Overclaiming – do not suggest your findings apply more widely than your evidence allows.
• Apologising for your research – acknowledge limitations, but stay confident about what you achieved.
• Leaving it until the last hour – a rushed conclusion is easy for markers to spot.

Useful Phrases for a Dissertation Conclusion

• “This study set out to…”
• “The findings demonstrate that…”
• “Taken together, these results suggest…”
• “This research contributes to the literature by…”
• “A key limitation of this study is…”
• “Future research could usefully explore…”
• “In conclusion, this dissertation has shown that…”

Dissertation Conclusion Checklist

• Restates the research aim briefly
• Answers every research question clearly
• Summarises key findings without repeating results
• States your contribution to knowledge
• Includes recommendations where relevant
• Acknowledges limitations honestly
• Suggests specific future research
• Introduces no new data or sources
• Fits within 5–10% of the total word count
• Matches what you say in your dissertation abstract

Frequently Asked Questions

Should a dissertation conclusion include references?

Usually only a few, if any. The conclusion focuses on your own findings and contribution, so heavy citation is not needed. You may briefly refer to key studies when explaining your contribution.

Can I write the conclusion before the other chapters?

You can sketch it early, but write the final version last. Your conclusion must reflect your final findings, so it should be revised once your results and discussion are complete.

Is the conclusion the same as the summary?

No. A summary simply restates what you did. A conclusion goes further: it answers the research question, explains what your findings mean, and shows why they matter.
