As doctors, we’ve often seen how something as simple as needing a doctor’s note can turn into a real headache. Whether it’s for work, university, or travel, people across the UK are often left waiting weeks for an appointment.
We found ourselves regularly writing letters for stressed patients who had missed flights, struggled with deadlines, or needed urgent documentation for housing, education, employment, or other important matters. The process was often unnecessarily slow and frustrating.
That’s why we started Merlin Health in 2024.
Our goal was to create a service that makes obtaining medical certificates simple, fast, and completely online — without the long waits or the stress of trying to secure an appointment.
With Merlin Health, you can request the medical certificate or letter you need from the comfort of your home, with applications reviewed and signed by UK GMC-registered doctors, often on the same day.
Since launching, we’ve helped thousands of people across the UK and internationally with a wide range of medical documentation, including fit-to-fly and unfit-to-travel letters, sick notes, university support letters, and emotional support animal documentation.
What began as a way to make healthcare documentation more accessible has grown into something much bigger: a trusted online medical service that saves time, reduces stress, and provides convenient access to genuine UK doctors when it matters most.
We’re a team of UK GMC-registered doctors, bringing together over 50 years of medical experience. At Merlin Health, our focus is on providing clear, reliable medical certificates and letters that people can use with confidence.
We started Merlin Health in 2024 after seeing how difficult it had become for people to access medical documentation when they needed it — whether for work, travel, university, or personal reasons. Our aim is simple: to take the hassle out of the process and give you a fast, trusted service you can rely on.
At Merlin Health, we make it simple to get the medical certificate or doctor’s letter you need — all signed by a UK GMC-registered doctor and sent straight to your email inbox the same day.
Some of the medical certificate we provide include:
Unlike waiting for a GP appointment, with Merlin Health there are no long delays, no waiting rooms, no hassle. Our doctors take the time to carefully review each request, ensuring every certificate is accurate, clear, and accepted by the relevant organisation.
For extra reassurance, we also include QR code verification on all documents, so employers, universities, airlines, and insurers can instantly confirm authenticity. This gives you peace of mind that your certificate will be taken seriously.
At Merlin Health, we believe getting a medical certificate shouldn’t be stressful, confusing, or slow. Our promise is to make the process as simple, clear, and dependable as possible — every single time.
