If your dissertation involves collecting data from real people — interviews, surveys, focus groups — you almost certainly need formal ethics approval before you’re allowed to start, and getting this wrong is one of the most common causes of dissertation delays in the UK. Collect data before approval comes through, and in the worst cases your findings can be rejected outright, forcing you to repeat the research. Here’s how the process actually works, and where applications most often get held up.
Why Ethics Approval Isn’t Just a Box-Ticking Exercise
Ethical review exists to protect your participants, protect you as the researcher, and safeguard the credibility of your findings. UK universities generally expect every student project involving human participants to reflect four core principles: participants are treated fairly and without harm, given clear information about the study, able to give genuinely informed consent, and free to withdraw at any point without any negative consequence. These aren’t optional extras — without them, your research generally can’t proceed at all.
Start This Far Earlier Than You Think
This is the single most common piece of advice across UK university guidance, and the one students most often ignore: ethics approval should be built into your research design from the proposal stage, not treated as a formality once your methodology is already finalised. Many dissertation projects are delayed specifically because students wait until they’re ready to start collecting data before applying — by which point the review process itself can take weeks. Start the application as early as your proposal allows. (See Sheffield Hallam University’s own guidance on ethical approval for a real example of this process.)
What Your Application Typically Needs to Cover
- The purpose of your study and what it involves
- Who your participants are and how you’ll recruit them
- How informed consent will be obtained — including a participant information sheet and a signed consent form
- How confidentiality and anonymity will be protected
- How data will be stored, and eventually destroyed
- What risks the research might pose, to participants or to you as the researcher, and how you’ll manage them
Always check your specific department’s exact form and requirements — some have their own version beyond the generic university template — and confirm with your supervisor which one applies to your project.
The Mistakes That Cause the Most Delays
UK ethics committees consistently flag the same issues, and they’re avoidable:
- Incomplete applications — missing sections, or vague answers instead of specific detail
- No attached consent form or participant information sheet — these need to be included with your application, not promised for later
- Unclear procedures for confidentiality — vague statements like “data will be kept safe” without specifying how
- Participant information sheets written in overly complex or academic language — these need to be genuinely accessible to someone outside your field, not written like a literature review
- Inconsistency between documents — if your data storage description differs between your proposal and your ethics form, expect a revision request
Data Protection: A Real Legal Requirement, Not Just Good Practice
If you’re collecting or storing personal data — anything that could identify a real individual, directly or indirectly — your project must comply with the Data Protection Act 2018 and UK GDPR. This means secure storage, restricted access, a lawful basis for processing the data, and a clear, stated retention period for how long you’ll keep it before deletion. This isn’t a separate concern from ethics approval; it’s typically assessed as part of the same application.
Different Studies, Different Review Routes
Not every project goes through the same process. Depending on your research, you might need departmental-level review only, full university ethics committee review, or — for health-related research involving NHS patients or resources — separate NHS ethics approval, which follows its own distinct timeline and process. Confirm with your supervisor early which route applies to your specific project, since this significantly affects your timeline.
A Practical Pre-Submission Checklist
- Have I clearly explained how informed consent will be obtained, not just stated that it will be?
- Have I attached a participant information sheet and consent form, written in accessible language?
- Is my data storage and destruction plan specific — where, how secured, and for how long?
- Does every document (proposal, ethics form, information sheet) describe my methodology consistently?
- Have I discussed my application with my supervisor before submitting?
How ASH Helps
Ethics applications and participant information sheets need exactly the kind of clear, precise, accessible writing that’s easy to get wrong under deadline pressure — especially when English isn’t your first language. ASH’s editing service checks clarity and consistency across these documents, alongside the guidance in our full guide to writing a dissertation methodology chapter, where your ethics approval is typically referenced.

FAQs
Do I need ethics approval for every dissertation?
Generally yes, if your research involves collecting data from human participants — interviews, surveys, focus groups. Purely secondary-data or literature-based dissertations may not need the same level of review, but always confirm with your supervisor.
What happens if I collect data before approval is granted?
This is treated seriously — in the worst cases, your findings can be rejected and you may be required to repeat the data collection, so always wait for formal approval before starting.
How long does ethics approval usually take?
This varies significantly by institution and by how complete your application is — incomplete or vague applications are the most common cause of delay, so starting early and submitting a thorough application first time genuinely matters.
Do I need separate NHS ethics approval?
Only if your research involves NHS patients, staff, or resources — this follows a distinct process and timeline from standard university ethics review. Confirm with your supervisor early if this might apply to you.
