At Merlin Health, we believe that online healthcare should be both accessible and ethical. Our mission is to make it easier for people to obtain verified medical documentation quickly and responsibly — without compromising medical integrity or patient safety.
We provide professionally written and doctor-signed medical certificates for a wide range of everyday needs, from travel and housing to employment, study, and wellbeing. Every document is carefully reviewed by an experienced, UK GMC-registered medical professional.
Our Medical Standards sets out the values, safeguards, and professional standards that guide everything we do. It reflects our commitment to maintaining accuracy, accountability, and transparency across every aspect of our service.
All Merlin Health medical letters and certificates are issued exclusively by UK GMC-registered doctors. Each doctor in our network has undergone extensive clinical training and follows strict ethical and professional standards in line with the General Medical Council’s (GMC) guidance on good medical practice.
Our doctors are responsible for ensuring that every document they issue is based on accurate, verifiable information and reflects sound professional judgement. We do not use templates or automation for clinical content — every letter is written and reviewed individually to ensure it meets the appropriate standard of medical validity and relevance.
To maintain the highest level of authenticity and prevent misuse, identity verification is a core part of our process. Before any medical certificate can be issued, the individual must upload a valid form of photo identification such as a passport or driving licence.
Our secure verification system ensures that each document is linked to the correct individual, protecting both patients and third parties who rely on our letters for decision-making. This step is non-negotiable and reflects our deep commitment to safeguarding trust and integrity within digital healthcare.
Merlin Health doctors will only issue a medical certificate once sufficient and appropriate supporting evidence has been provided. This may include clinic letters, discharge summaries, medical records, or written descriptions that allow the doctor to make an informed and professional decision.
Our doctors review every submission carefully, and if the information is unclear or incomplete, we will contact the applicant for clarification before proceeding. This ensures that each document we issue is based on clear, verifiable evidence and reflects the applicant’s true medical situation accurately.
Merlin Health does not issue medical certificates automatically or on request alone — every letter is written only after a qualified doctor is satisfied that enough information has been provided to justify it.
Even though our service is non-clinical, patient safety remains our highest priority. Our doctors are trained to recognise potential red flags or safeguarding concerns within the information provided. Where any indication of risk or vulnerability is identified — such as signs of mental distress, self-harm, or abuse — the doctor will take appropriate steps in line with GMC and NHS safeguarding guidance.
We aim to ensure that our platform remains a responsible and compassionate environment, where individuals are treated with dignity and care at all times.
Protecting your personal and medical information is central to our mission. All data shared with Merlin Health is stored securely and handled in compliance with the UK General Data Protection Regulation (GDPR) and Data Protection Act 2018.
Only authorised medical professionals involved in preparing your letter have access to your information. We never share data with third parties without your explicit consent, and all uploads, documents, and communications are encrypted to maintain the highest standards of privacy and security.
Merlin Health complements — not replaces — NHS care. Many GP practices face heavy administrative pressure managing requests for non-urgent letters and certificates. By responsibly providing these documents online, we help free up valuable NHS time and resources so that GPs can focus on direct patient care.
Our service provides a safe, efficient alternative for people who need verified medical evidence quickly and conveniently, without adding strain to already stretched primary care services.
We believe in openness about how our service operates. Each Merlin Health letter includes the doctor’s name, GMC registration number, and a verification QR code, allowing recipients such as employers, councils, or travel providers to confirm authenticity instantly.
We welcome feedback and take it seriously — using it to refine and improve our processes continuously. Our goal is to uphold a gold standard for trust, professionalism, and reliability in online medical documentation.
Merlin Health exists to make access to essential medical documentation faster, safer, and simpler — without compromising ethics or professional standards.
Every letter we issue is:
We are committed to maintaining the highest standards of medical professionalism and ensuring that every Merlin Health document can be trusted by the people and organisations who rely on it.
