Fast, efficient — amended later for free
Fast, efficient service. Certificate the same day. When the event required specific wording, MedicalCert updated it promptly at no extra charge. Excellent aftercare.
Clinician-Led Medical Assessment
MedicalCert operates as a clinician-led service. Every certificate and medical letter is reviewed by a GMC-registered doctor and assessed on its individual merits. We do not generate automated approvals — each request is evaluated using professional medical judgement and accepted clinical standards.
Confidential Medical Assessment
You complete a secure online form outlining your medical history, symptoms, and the purpose of your request. This information forms the basis of the clinical review.
Professional Clinical Evaluation
A GMC-registered doctor examines the information provided, considering current symptoms, functional impact, stability of any existing conditions, and whether documentation is medically justified at that time.
Issuance Where Clinically Appropriate
If the assessment supports your request, a signed medical certificate or letter is issued. Where there is insufficient clinical basis, documentation will not be provided.
MedicalCert is a digital platform that facilitates independent clinical review by UK GMC-registered doctors.
Clinical decisions are made by the reviewing clinician.
Online Medical Certificates from UK Registered Doctors — No Appointment Needed
MedicalCert is a UK clinician-led platform operated by Knobel Health Limited that provides online medical certificates and doctors letters following individual assessment by GMC-registered GPs. Every request is reviewed by a qualified doctor — no automated approvals, no templates. If a certificate cannot be issued on clinical grounds, you receive a full refund automatically.
Certificates are delivered as signed, verifiable PDFs direct to your inbox — same day or by 9AM next morning — and are accepted by UK employers, universities, travel insurers, airlines, and housing providers.
Why Get a Medical Certificate Online?
NHS GP appointments for medical certificates and doctors letters are not always straightforward — many practices do not prioritise administrative letters, appointment slots are limited, and waiting times for a certificate can run to several weeks. For time-sensitive situations — a travel insurance claim, an employer deadline, or an urgent housing request — this is often too slow.
MedicalCert provides a structured alternative: a genuine clinical review by a GMC-registered GP, conducted entirely online, with documentation issued the same day where clinically appropriate.
Same day, no waiting room
Submit your evidence any time. Most certificates are reviewed and issued the same day, or by 9AM the following morning.
Genuine clinical review
Every request is assessed individually by a GMC-registered GP. Documentation is only issued where clinically appropriate — not automatically.
Accepted by organisations
Certificates include the doctor’s GMC registration number and a QR verification code — meeting the requirements of employers, insurers, airlines, and institutions.
Secure and confidential
Your medical information is handled in accordance with UK data protection law. ICO registered. GDPR compliant.

Frequently Asked Questions
How do I get an urgent medical letter or certificate?
It’s quick and easy! Simply complete the brief online questionnaire and complete the payment. After purchasing your medical letter online, a doctor will review the medical evidence the same day, and we will provide you with your unique medical certificate for you to present to your work place or institution. There is no need to have a telemedicine or online consultation to receive a medical letter. Our doctors may call or email you directly if they have any additional questions.
Can I get a doctors note or medical letter without seeing a doctor?
All medical letters including sick notes must be signed and certified by a doctor, but you do not always need to see a GP to get one. Our revolutionary service allows you to be assessed by one of our GPs without needing an appointment, simply by uploading your concerns and evidence through our forms. One of our GPs will then consider your medical history, current symptoms, and any potential risks associated with your condition and work or study environment before issuing your medical certificate. You will then receive the letter directly to your inbox.
What medical evidence will you require?
We will require you to upload:
✓ A photo / copy of your Passport or Driver’s Licence to confirm your identity
✓ Complete a short medical questionnaire
✓ Upload a short video or photographs via your mobile confirming your symptoms and reason for a medical letter
Do you provide refunds?
We always provide full refunds if we are unable to provide a Medical Letter in your situation, so you can submit your requests with peace of mind. Once a medical certificate or sick note has been issued we are unable to offer refunds.
How long can you issue sick leave for?
Our sick notes are valid for up to 14 days at a time per certificate, but can be extended if you remain unwell, or if you have any form of evidence that your sickness is ongoing.
How soon will I receive my medical letter or certificate?
Our team of GPs will review your medical evidence and questionnaire on the same day and provide you with your medical letter or certificate within 1 working day. We also offer a subject to clinical assessment by 9 a.m. service for medical letters for evidence that has been uploaded by 11 p.m. (UTC/GMT) Sunday - Thursday. With our express overnight service you will receive your medical letter or certificate in your inbox overnight by 9 a.m. the next day. For example, an application submitted at 11 p.m. on a Thursday night will be assessed and delivered by 9 a.m. on Friday morning.
Who will sign my medical letters and medical certificates?
All of the doctors at Medical Cert are fully licensed GMC-registered GPs, unlike many other services who use very junior non-specialist doctors, which may sometimes cause their letters to be rejected. You can submit any letters you receive from Medical Cert with full confidence, knowing that an experienced GP has signed your document. We are a UK-based healthcare service but the certificates can be used internationally. All of our Doctors are registered GPs with the UK General Medical Council.
Can a sick leave letter be backdated?
Yes, we are able to backdate letters provided you are able to submit some evidence to indicate when you became unwell. Evidence can be in the form of videos, photos, copies of discharge summaries or prescriptions, or any test results you may have at hand. We also accept screenshots of relevant information from your NHS app.
Can you complete a specific form required by my institution or workplace?
Yes, in most cases we can help with special forms required by some institutions. Simply upload the required form with your medical evidence.
Can your doctor’s letters be verified by my workplace or institution?
Absolutely. Each letter or certificate issued will have a unique reference number and can be verified free of charge by emailing us at verify@medicalcert.co.uk.
Can you issue an NHS “Statement of Fitness for Work” also known as “Fit Notes”?
We facilitate access to private medical letters and do not issue Med3 Fit Notes. Med3 Fit Notes are required for UK government benefit applications and can be obtained through your registered NHS GP. If you require a private medical letter for most other purposes, we are here to assist you in obtaining a doctor’s letter conveniently and quickly.
Online Medical Certificates Reviewed by UK Doctors
MedicalCert provides access to independent UK General Medical Council (GMC) registered doctors for the clinical review and issuance of medical certificates where appropriate. Documentation is assessed individually and issued only when there is a clear medical basis.
Understanding Medical Certificates
A medical certificate is a formal document completed and signed by a registered doctor. It confirms illness, recovery, or fitness for work, study, travel, or specific activities. Employers, universities, insurers, and other organisations may request medical documentation as evidence.
Each UK medical certificate issued through MedicalCert includes relevant patient details, clinical opinion, applicable dates, and the doctor’s GMC registration information.
Clinical Review Process
Complete a structured medical questionnaire and upload supporting information where relevant.
A GMC-registered doctor reviews your information using professional clinical judgement.
If sufficient medical justification exists, a signed medical certificate is issued digitally.
Common Documentation Requests
Sick Notes
Medical certificates for short-term work absence or employer documentation.
Student Certificates
Absence documentation for universities, colleges, and academic institutions.
Fit-to-Fly Letters
Travel-related documentation following illness or pregnancy.
Fitness Certificates
Medical clearance for sports participation or physical activity.
Visa Medical Certificates

Medical Certificates in a Digital Setting
Traditionally, obtaining a GP medical certificate required an in-person appointment. Digital healthcare platforms now allow structured remote assessment where clinically suitable. Documentation issued digitally is subject to the same professional standards and regulatory requirements as paper certificates.
All decisions are based on the information provided and the doctor’s professional judgement. Where a remote assessment is not appropriate, documentation will not be issued and alternative advice may be given.
Clinical Governance
Doctors providing services through MedicalCert are registered with the UK General Medical Council and are bound by professional duties of accuracy, honesty, confidentiality, and patient safety.
Medical certificates are issued only where clinically appropriate. If documentation cannot be supported on medical grounds following review, a refund is provided.
Are digital medical certificates accepted in the UK?
Many employers and institutions accept private medical certificates issued by registered doctors. Requirements may vary, so it is advisable to check directly with the requesting organisation.
Does payment guarantee a certificate?
No. Payment covers the clinical review process. A certificate is issued only where clinically justified.
Are complex conditions suitable for remote certification?
Some situations require in-person assessment. If remote review is not appropriate, documentation will not be issued.
