Illness or a serious personal problem can make a deadline impossible. Here is what counts, how to apply, and what evidence UK universities usually ask for.

Illness, bereavement or a serious personal problem can make it impossible to meet a deadline. UK universities have a process for this, but it has strict rules and time limits. This guide explains how to apply for extenuating circumstances and an extension.
What counts as extenuating circumstances
Universities look for serious events that were outside your control and that affected your ability to study or sit an assessment.
- Illness or injury, including mental health problems.
- Bereavement or serious illness of a close family member.
- Serious accident, crime or emergency.
- Major disruption linked to a disability or caring responsibilities.
Things that usually do not count are poor time management, a heavy workload, minor illness that did not affect the deadline, and events you could have planned for. Rules differ, so read your policy.
How to apply, step by step
- Find your university's policy. Search for "extenuating circumstances", "mitigating circumstances" or "extensions".
- Check the deadline for applying. It is often a few working days after the assessment deadline, and sometimes before it.
- Complete the official form. Say what happened, when, and how it affected your work.
- Attach evidence, such as a doctor's letter, a death certificate or a police report. Some universities accept a short self-certificate for brief illness.
- Keep a copy of everything and note the date you submitted it.
- Wait for the decision and follow any new deadline you are given. Our free assignment deadline planner can turn it into a day-by-day plan.
Extension, deferral or resit
| Outcome | What it usually means |
|---|---|
| Short extension | A new deadline, often a few days to a couple of weeks. |
| Deferral | The assessment moves to a later date, such as the resit period, and counts as a first attempt. |
| Uncapped resit | A second attempt where your mark is not limited to the pass mark. |
Fit to sit and other rules
Many universities have a "fit to sit" rule. If you take an exam or submit work, you are saying you were well enough, and you may not be allowed to claim circumstances afterwards. Read the rule before you decide whether to sit.
Tips for a stronger application
- Apply early. Late applications are often refused.
- Be factual and specific, and explain the effect on your work.
- Get evidence from a professional, dated close to the event.
- Talk to your personal tutor or your students' union advice service. It is free.
- If you have a long-term condition, ask about support plans and reasonable adjustments.

Frequently asked questions
Do extenuating circumstances change my grade?
No. They do not add marks. They change the conditions of the assessment, for example by giving you more time or a fresh attempt.
Can I apply after I miss a deadline?
Some universities accept late applications with a good reason. Many have a strict window, so apply as soon as you can.
Do I need a doctor's note?
Often yes, but some universities accept a self-certificate for short illness. Your policy says which evidence they accept.
What if my request is refused?
You can usually appeal. Ask for the reasons in writing and contact your students' union advice service for support.
