What is a University & College Sickness Certificate?
A doctor’s note for university is an official document from a GMC-registered UK doctor confirming your illness or health condition and its impact on your academic studies.
UK universities require this specific document for absences, missed exams, coursework extensions, deadline deferrals, and mitigating circumstances submissions.
ZoomDoc issues university doctor’s notes entirely online, with an average turnaround of 1-2 hours. No GP appointment needed. Upload your evidence, our doctors review it, and your letter arrives by email the same day – signed by a UK GMC-registered doctor, with a QR code for instant verification by your university or college.
Our doctors follow up with health advice and support for your condition when issuing your certificate.

When do you need a doctor’s note for university?
Most UK universities allow students to self-certify short absences of up to seven consecutive days without a doctor’s note.
Beyond that threshold – or for any academically significant event – a signed medical certificate from a GMC-registered doctor is typically required. The specific situations where you will need one include:
Absence from lectures, seminars, or placements
If your illness has kept you away from university for more than seven consecutive days, your institution will require a GP-signed medical certificate rather than self-certification. ZoomDoc’s letter confirms your condition, the dates your illness started, whether it is ongoing, and why it prevented your attendance.
Missed exams or assessments
Missing an exam due to illness is one of the most common reasons students need a doctor’s note. Many universities require a medical certificate for any missed exam regardless of duration. ZoomDoc’s letter can confirm your condition affected your ability to attend or sit the exam, supporting your request for rescheduling, deferral, or special consideration.
Coursework extensions and deadline deferrals
If illness has prevented you from completing an assignment or meeting a coursework deadline, a medical letter from ZoomDoc can support a formal extension request. The letter will confirm when your symptoms began and how your condition affected your ability to work – the specific evidence most university systems require for an extension to be granted.
Mitigating circumstances submissions
If your health has affected your academic performance more broadly – impacting exam results, attendance records, or your ability to complete the year – a ZoomDoc medical letter can support a formal mitigating circumstances submission. The letter includes an explicit academic impact statement describing how your condition has affected your studies, which is what most mitigating circumstances panels require.
Mental health conditions affecting studies
Mental health conditions – including anxiety, stress, depression, and burnout – are treated with the same clinical rigour as physical illness. If a mental health condition has affected your attendance, exam performance, or ability to submit work, our doctors can issue a letter describing the impact on your studies and, where appropriate, recommending a period of rest or academic adjustment.
Who needs a doctor’s note for university?
The situations shown here reflect the most common queries ZoomDoc’s doctors receive from students, and the specific evidence universities and colleges typically ask for in each case.
Ill during exam season
Falling ill during exam season is one of the most stressful situations for any student. If you are too unwell to sit an exam, your university will require a medical certificate confirming your condition and the dates your symptoms prevented you from attending. ZoomDoc can issue this the same day – upload your evidence before 9pm and your letter will be with you that evening, ready to submit to your department or student services.
Common questions in this situation:
- Can I get a same-day doctor’s note if I missed an exam this morning?
- What do I need to submit to defer an exam due to illness?
- Will my university accept an online medical certificate for a missed exam?
Long-term illness or chronic condition affecting attendance
A long-term condition – whether physical or mental – that has affected your attendance or academic performance across a term or academic year may require a medical letter for a formal mitigating circumstances submission or academic progress review. ZoomDoc’s doctors can issue a letter describing your condition, its duration, and how it has impacted your studies.
Common questions in this situation:
- Can I get a medical letter for mitigating circumstances covering the whole term?
- My anxiety has affected my grades – can I get a doctor’s note for that?
- What medical evidence do I need for a mitigating circumstances panel?
Deadline extension due to illness
If illness has prevented you from completing an assignment on time, a ZoomDoc medical letter can support your extension request. The letter confirms when your symptoms began, whether you were too unwell to work, and whether the condition is ongoing or resolved – the three pieces of information most extension request forms ask for.
Common questions in this situation:
- Can I get a doctor’s note for a university essay extension?
- What evidence do I need to request a coursework deadline extension?
- Will a medical letter from ZoomDoc be accepted for a deadline extension?
International student needing UK medical documentation
International students enrolled at UK universities can use ZoomDoc’s service from anywhere – you do not need to be registered with a UK NHS GP. The process is entirely online and requires only a short video, a health questionnaire, and photo ID. The certificate is in English and complies with UK medical standards, making it accepted across UK institutions regardless of your nationality or home country.
Common questions in this situation:
- Can international students get a UK doctor’s note for university?
- I don’t have an NHS GP – can I still get a sick note for university?
- Does ZoomDoc issue medical letters for international students in the UK?

Who signs the university, college and school sickness certificate?

We are a UK-regulated healthcare provider, and all of our doctors are registered with the General Medical Council (GMC).
What can I use this medical letter for?
Our medical letters can be submitted to any university, college or school as evidence of a health condition.
They outline the reason for your absence, or any mitigating circumstances that may have affected your studies, exams or coursework.
Can I use a private doctor’s note for university instead of an NHS GP letter?
Yes. UK universities accept medical certificates from any doctor on the GMC register – not only your registered NHS GP. This is a common source of confusion for students.
NHS GPs issue Med3 fit notes, which are designed for workplace absence and Statutory Sick Pay – not university submissions. Many NHS GPs will not provide a separate letter for university purposes, or will charge a private fee and have a waiting time of days or weeks. A private medical certificate from a ZoomDoc GMC-registered doctor serves exactly the same evidential purpose and carries equal weight with your institution.
Common questions about NHS vs private doctor’s notes for university:
- My GP won’t provide a letter for university – can I use ZoomDoc instead?
- Is an online doctor’s note as valid as an NHS sick note for university?
- Do universities accept private medical certificates?
- Can I get a same-day doctor’s note for university without an NHS appointment?
Can I get a doctor's note for university for mental health reasons?
Yes. ZoomDoc doctors can issue medical letters for mental health conditions including stress, anxiety, depression, and burnout, where these have impacted your coursework, attendance, or exams. The letter will describe how your condition has affected your academic performance and may recommend a period of rest or adjustments. Mental health is treated with the same clinical rigour as physical illness.
Can I get a doctor's note for a missed exam?
Yes. Missing an exam due to illness is one of the most common reasons students need a doctor’s note. ZoomDoc can issue a certificate confirming that your condition affected your ability to attend or sit the exam, supporting your request for rescheduling, deferral, or special consideration. Upload your evidence before 9pm for same-day issue.
Can I get a doctor's note for a university extension or mitigating circumstances?
Yes. If your health has affected your ability to submit coursework on time or perform to your usual standard, a ZoomDoc medical letter can support a formal request for a deadline extension or a mitigating circumstances submission. The letter will confirm your condition, when symptoms began, and how your health has impacted your studies – the specific evidence most university panels require.
My NHS GP won't provide a letter for university - can I use ZoomDoc?
Yes. NHS GPs are not obligated to provide medical letters for university purposes, and many will decline or have waiting times that make same-day documentation impossible. ZoomDoc’s GMC-registered doctors issue university medical letters entirely online, with no appointment needed. Our certificates carry the same legal and academic weight as an NHS GP letter, as both are signed by doctors on the GMC register.
Can I get a doctor's note for university without leaving home?
Yes. The entire ZoomDoc process is online. You upload a short video, complete a health questionnaire, and provide a photo ID. Our doctors review your evidence and issue your certificate by email – typically within 1-2 hours. There is no in-person appointment, no waiting room, and no need to visit a clinic.
Does the doctor's note include an academic impact statement?
ZoomDoc’s average turnaround is 1-2 hours from the time you upload your evidence. Our doctors operate 7 days a week between 9am and 9pm GMT. Upload your evidence before 9pm and you will receive your certificate the same day.
Can I get a backdated doctor's note for university?
Our doctors can issue a certificate covering the dates your illness occurred, provided you can supply credible evidence of your symptoms during that period – such as a video account, pharmacy records, or any other supporting documentation. Our doctors will assess each case on its clinical merits. We are unable to issue certificates for periods where no clinical justification exists.
