MedicalCert by Nobel Medical.
MedicalCert provides a platform for fast, reliable, and legally valid medical certificates. Issued by UK-registered doctors and delivered online so you can get the documentation you need for work, travel, study, or everyday life, without the wait or hassle.
About MedicalCert
MedicalCert is a digital marketplace that connects patients with independent GMC-registered doctors for private medical consultations. We provide a structured, secure way for individuals to request medical documentation where clinically appropriate.
All medical certificates and letters issued through the platform are reviewed individually by an independent GMC-registered doctor and assessed using professional medical judgement in accordance with UK regulatory standards.

Founded by a practising UK GP
MedicalCert was founded by Dr Maria Knöbel, a GMC-registered GP and Medical Director of Nobel Medical LLC. Dr Knöbel holds a BSc (Hons) in Biomedical Sciences from Imperial College London and an MBBS (with Merit) from Barts and The London School of Medicine and Dentistry.
She is a Member of the Royal College of General Practitioners (MRCGP) and holds international board certification in Lifestyle Medicine (IBLM), with additional specialist training in Menopause Care and Sports Medicine. Her background spans NHS and private general practice, e-consultations, and remote triage, experience she draws on directly in shaping MedicalCert’s clinical standards.
Dr Knöbel established the platform to provide a structured, transparent pathway for individuals who need medical documentation outside of routine GP appointments, maintaining independent clinical judgement at the centre of every decision.
Full profileIndependent, clinically governed documentation
Documentation is issued only where there is a clear clinical basis, following individual review and accepted clinical practice.
Clinical Oversight
Clinical decisions are made independently by GMC-registered doctors who are accountable to their own regulatory body. Documentation is issued only where there is a clear clinical basis.
Responsible Clinical Lead
Dr Maria Knobel (GMC 7495073) provides clinical oversight for the platform. Registration can be verified via the official GMC register.
Independent Clinical Judgement
MedicalCert does not provide automated approvals. Each request is sent directly to an independent GP who assesses it individually using recognised medical standards and accepted clinical practice.
No Commercial Influence
Clinical decisions cannot be influenced by commercial outcome. The doctor decides, not the platform.
Platform & Administrative Structure
Payment processing and digital administration are managed through Nobel Medical LLC, a United States limited liability company registered in Delaware. This provides secure infrastructure but does not replace clinical oversight or professional regulation.
Transparency & Governance
We are committed to transparency, patient safety, and regulatory compliance. Refunds are provided automatically where the doctor determines documentation cannot be issued following review.

A structured and clinically responsible pathway
Our mission is to provide a structured, transparent, and clinically responsible pathway for individuals who require medical documentation. We aim to balance accessibility with professional integrity by ensuring that every request is assessed independently and in accordance with recognised UK medical standards.
We believe medical documentation should be issued based on clinical judgement, not commercial incentive. By maintaining independent clinical oversight and automatic refunds where documentation cannot be issued, we prioritise fairness, accountability, and patient trust.
Timely documentation, without replacing your GP
Access to timely medical documentation can sometimes be difficult within traditional healthcare pathways, particularly where appointments are limited or documentation is required for administrative purposes rather than ongoing medical treatment.
MedicalCert was established to provide a structured, transparent alternative for individuals who require documentation such as sick notes, travel certificates, or supporting letters. The platform connects you directly with an independent GMC-registered doctor for review, without replacing your usual GP or primary care provider.
We do not provide emergency care, diagnosis for complex conditions, or substitute ongoing medical management. Where appropriate, individuals are advised to consult their own GP or relevant healthcare service.
Independent review, from submission to outcome
Each request is sent directly to an independent GMC-registered doctor for individual review using professional judgement and accepted clinical practice.
Secure Request Submission
You complete a structured, secure request outlining relevant medical history, symptoms, and the purpose of the documentation requested.
Independent Clinical Assessment
Your submission is sent directly to an independent GMC-registered doctor who reviews the information using recognised medical standards and accepted clinical practice. Automated approvals are not provided.
Clinically Appropriate Outcome
The doctor issues documentation only where there is a clear clinical basis. Where the doctor determines documentation cannot be issued, an automatic full refund is provided.
Governance & Accountability
Clinical decisions are made independently by the reviewing doctor and remain accountable under UK professional regulatory standards.
