Illness, a family emergency, a placement that swallowed your week — sometimes an assignment deadline becomes impossible for reasons that have nothing to do with effort. UK universities know this, and almost all of them have a formal system for it: the short extension, and for bigger problems, the extenuating (or mitigating) circumstances process. Students often lose marks they did not need to lose simply because they asked too late, asked the wrong person, or did not ask at all. This guide explains when extensions are granted, how to ask properly, what to say — including a full email template you can adapt — and what your options are if the answer is no.
Extensions and extenuating circumstances: two different doors
First, know which door you need, because they work differently at most universities:
- A short extension is usually a modest delay — commonly a few days to a week — for coursework deadlines. At many universities these are granted by your module leader or through your student portal, sometimes with a simple form and no medical evidence required for the shortest requests. The rules are in your course handbook and your university’s assessment regulations.
- Extenuating / mitigating circumstances (ECs) are the formal route for serious situations: significant illness, bereavement, caring emergencies, or anything that seriously affected a whole assessment period. EC claims usually go to a central panel, need evidence, and can result in an uncapped resit, a deferred attempt, or a deadline moved by weeks rather than days. If your situation is bigger than one deadline, ECs — not a string of extension emails — are the right route, and your students’ union advice service or personal tutor can help you frame the claim.
When extensions are usually granted
Universities differ in detail, but short extensions are commonly granted for:
- Short illness around the deadline (a few days of flu, a migraine condition flaring)
- A family emergency, bereavement or urgent caring responsibility
- A medical appointment or treatment clashing with the deadline
- Disability or long-term condition flare-ups — though if you have a support plan, adjustments may already be built in, so check it first
- Genuine technical failure at submission (portal outages happen; keep screenshots)
And commonly not granted for: having several deadlines in the same week (that is considered normal degree life), a laptop dying without any backup of your work, part-time work commitments, or simply starting late. Knowing this matters, because a request that the rules exclude wastes the goodwill — and the time — you may need for a legitimate one later.
How to ask: the rules that decide outcomes
Ask before the deadline, not after. This is the single biggest factor. A request sent 48 hours before submission is a plan; the same request sent the morning after reads as an excuse, and many universities will not consider retrospective extension requests at all (you would be pushed to the EC route instead).
Ask the right person, through the right channel. Check your handbook: it may be your module leader, your personal tutor, or an online form on the student portal or VLE. If a form exists, use it — an email to the wrong inbox can sit unread past your deadline.
Be specific about what you need. “A few extra days” is weaker than “an extension to [specific date], which gives me four additional days”. Show, briefly, that a short delay actually solves the problem — tutors grant requests that end with a finished assignment, not requests that postpone a crisis.
Provide evidence where the system asks for it. Short extensions sometimes need none; longer ones and EC claims usually need something: a fit note or medical letter, a death certificate for bereavement claims, screenshots for IT failures. If evidence will take time to obtain, say so in your request and give the date you will supply it — most systems accept evidence shortly afterwards if you have told them it is coming.
Keep the tone short, factual and professional. One or two sentences about the circumstance, no life story, no apology essay. Tutors read dozens of these; clarity is kindness.
What NOT to say
- Do not invent or exaggerate a circumstance. Fabricated evidence is treated as fraud at UK universities and can end a degree, not just an assignment.
- Do not blame the module, the teaching or another deadline. Even when it feels justified, it reframes your request as a complaint and rarely helps.
- Do not promise what you cannot deliver (“I will definitely submit by Friday” when Friday is impossible). A second request after a broken promise almost never succeeds.
- Do not send the request in a panic at 3 a.m. with no subject line. Write it calmly, in working hours if you can, with your student number, module code and current deadline in the first lines — you are making it easy to say yes.
Email template you can adapt
Copy the structure, replace the brackets, and trim anything that does not apply. Send it to the person or address your handbook specifies.
Subject: Extension request — [Module Code] [Assignment Name] — [Your Student Number]
Dear [Dr/Professor Surname / Module Leader],
I am writing to request a short extension for the [assignment name] in [module code and title], which is currently due on [date].
[One or two factual sentences about the circumstance: e.g. “I have been unwell with flu since Tuesday and have been unable to work on the assignment this week” / “A family emergency required me to travel home on Wednesday, and I have lost the days I had planned for completing this assignment.”]
I have completed [brief honest progress statement: e.g. “the research and roughly half of the draft”]. With an extension to [proposed date], I will be able to submit the finished assignment by that date. [If evidence applies: “I can provide [a fit note / supporting evidence] and will upload it by [date].” / If none: “I understand evidence is not required for a short extension, but I am happy to provide more detail if helpful.”]
Thank you for considering this request. I apologise for the disruption and appreciate your understanding.
Kind regards, [Your full name] [Student number] · [Programme and year]
If the answer is no
A refusal is not the end; it changes the calculation. Check three things in your university’s regulations:
- Late submission window and capping. Many universities accept work a few days late with a mark penalty — commonly the grade is capped at the pass mark (40% at undergraduate level) if submitted within the late window, and zero after it. A capped pass is almost always better than a non-submission, which can mean failing the module and a capped resit. Read your own regulations: the exact windows vary.
- The EC route. If the refusal was on a short-extension request but your circumstances are serious, a formal extenuating circumstances claim may still be open — often with its own deadline shortly after the assessment. Do not assume the refusal closed every door.
- Your remaining time. However many hours you have left, a structured partial submission beats a blank one: an introduction, structured sections and the strongest material you have can collect real marks, where nothing collects none.
Get advice quickly from your personal tutor or students’ union — they handle these situations weekly and know your university’s specific flexibilities.
Use the extension well
An extension only helps if the extra days work differently from the days that ran out. Spend the first hour planning the assignment into sections with rough word counts and order of writing; then write in that order, shortest wins first to build momentum. Protect the new deadline like the original one — tutors can see the submission timestamp, and an extension followed by another late scramble closes the door next time. And when it is submitted, note what actually caused the crunch, because the pattern (starting the literature search too late, underestimating referencing time) is the cheapest lesson in your degree.
One last thing
If deadlines regularly collide with work, placements or life — rather than one genuine emergency — structured support can change the arithmetic: a model answer to study from can show you the structure and standard in a fraction of the time it takes to discover them alone.
