Medical Translation Services in London and the UK

What are medical translation services?

Medical translation services are ISO 17100-controlled language services that convert healthcare, clinical, pharmaceutical and medical-device documents between languages using specialist medical translators, so hospitals, sponsors, manufacturers and patients in the UK can meet NHS, MHRA and Home Office requirements safely and legally. Accuracy is safety-critical: mistranslated dosages, allergies or surgical instructions cause misdiagnosis, wrong treatment and patient harm, which is why the workflow is standardised, audited and staffed by qualified medical linguists rather than generalists.

Which documents count as medical translation?

Medical translation covers 6 document families: patient records, clinical trial documents, medical device IFUs, pharmaceutical labelling, regulatory submissions and public health communications, each governed by different UK compliance rules.

• Patient records — discharge summaries, GP referrals, medical histories, prescriptions, radiology and pathology reports.
• Clinical trial documents — protocols, informed consent forms, investigator brochures, CRFs, PROs, ethics submissions, CSRs.
• Medical device documentation — IFUs, UI strings, technical files, clinical evaluation reports, post-market surveillance.
• Pharmaceutical documentation — SmPCs, PILs, packaging and labelling, MHRA and EMA submissions, pharmacovigilance reports.
• Regulatory submissions — dossiers, variations and correspondence for the MHRA, EMA and HRA.
• Public health communications — NHS patient information leaflets, vaccination materials, safeguarding notices.

How does medical translation differ from general translation?

Medical translation differs from general translation on 4 dimensions: terminology precision (SNOMED CT, MedDRA, ICD-11), regulatory liability (MHRA, EMA, HRA), mandatory back-translation for high-risk documents, and certified translator qualifications beyond linguistic competence. Medical translators hold degrees or verified professional experience in biology, nursing, pharmacy, medicine or life-sciences linguistics, because language fluency alone is insufficient for clinical content.

What certifications and quality standards govern medical translation?

Our medical translation operates under ISO 17100 for translation services, with additional alignment to ISO 13485 context for medical device work, ISO 14971 references for risk management terminology, GDPR and UK DPA 2018 for patient data, and NHS Digital confidentiality principles for records handling. The full framework is documented on our Medical Translation Quality, Compliance & Process page.

What does ISO 17100 mean for medical translation?

ISO 17100 requires medical translations to be produced by a qualified translator, revised by a second qualified linguist, project-managed against documented processes, and delivered from an agency with defined translator competence, technology and record-keeping controls. In practice this maps to the TEP workflow — translation, editing, proofreading — with clause 5.3 revision as the non-negotiable second-pair-of-eyes step for every medical file.

How is patient data protected under GDPR and NHS confidentiality?

Patient data in medical translation is protected under UK GDPR and DPA 2018 through signed translator NDAs, encrypted file transfer, restricted-access project systems, purge-on-completion retention rules and NHS confidentiality-code-aligned handling of identifiable records. Access is limited to the assigned translator, reviser and project manager; source and target files are archived in encrypted storage or deleted per client instruction.

Certified, sworn, notarised or apostilled — which medical translation do you need?

UK medical translation buyers choose between 4 attestation levels: certified (agency statement of accuracy, accepted by NHS and Home Office), sworn (signed by a sworn translator for overseas courts), notarised (translator identity witnessed by a UK notary) and apostilled (Foreign Office legalisation for Hague Convention countries).

When is a certified medical translation enough?

A Certified Medical Translation is enough for NHS admissions, GMC registration, UK Home Office visa medical evidence, private clinic records and UK insurance claims — where the agency’s signed statement of accuracy under ISO 17100 satisfies the receiving body.

When do you need a sworn or notarised medical translation?

Sworn medical translations are required by many EU civil courts and consulates, while notarised medical translations are required when overseas authorities need a UK notary public to witness the translator’s signature — common for adoption medical files and cross-border malpractice cases.

When does a medical translation need an apostille?

A medical translation needs an apostille when it must be recognised in a Hague Convention country, adding UK Foreign, Commonwealth & Development Office legalisation on top of the certified or notarised translation for use abroad.

Who uses medical translation services?

Our medical translation clients span 6 distinct buyer groups: NHS trusts and integrated care boards, private hospitals and clinics, pharmaceutical companies, CROs and biotech sponsors, medical device manufacturers, and private patients handling immigration, insurance or overseas treatment. Every segment has its own regulatory obligations, document types and quality expectations — and our 1,500+ accredited linguists are matched to each specialism accordingly. We serve clients across London and the wider UK, as well as international organisations that require UK-regulatory-ready output.

NHS trusts and healthcare providers

NHS trusts commission medical translation for patient information leaflets, safeguarding communications, discharge summaries for overseas patients and multilingual public-health campaigns, procured on framework rates aligned to NHS England’s equality and health-inequality duties. Effective communication with patients is a professional obligation for clinicians, and accurate translated documentation is a core part of meeting that standard. Our workflows are built to comply with NHS guidelines and UK GDPR requirements, ensuring that sensitive patient data is handled securely at every stage. Public healthcare bodies also rely on us for GP referral letters, pathology reports and radiology summaries when records cross language boundaries.

Pharmaceutical companies and CROs

Pharmaceutical sponsors and CROs commission clinical trial translations — protocols, ICFs, investigator brochures, PROs, CRFs, ethics submissions and CSRs — plus MHRA and EMA submission translations, with terminology managed against MedDRA and EDQM standard terms. Our ICH-GCP-ready processes mean that translated trial documents meet international standards for research integrity and regulatory review. SmPCs, PILs, labelling copy and pharmacovigilance narratives are additional deliverables we produce for pharmaceutical clients preparing UK and EU market authorisation dossiers. The MHRA is the UK regulator for medicines and medical devices, and all submission-bound translations we deliver are formatted and certified to satisfy its documentation requirements.

Medical device manufacturers

Medical device manufacturers commission IFU, labelling, UI string and technical file translation into the official languages determined by each EU member state where the device is placed on the market, plus UK-specific English, meeting UK MDR 2002, EU MDR 2017/745 and IVDR 2017/746 language requirements. Clinical evaluation reports and post-market surveillance documentation are equally subject to strict linguistic accuracy standards, and our subject-matter linguists hold relevant life-sciences credentials to handle this content. A device that carries an incorrectly translated safety instruction is a regulatory and patient-safety risk — which is why each IFU translation passes through our full ISO 17100 four-stage review before delivery.

Private patients and immigration applicants

Private patients commission certified medical translations for UK visa medicals, overseas treatment, insurance claims and family reunification, delivered from £30 per page with same-day turnaround available for short documents placed in London before 11:00 GMT. Medical histories, discharge summaries, prescriptions and GP referrals are among the most frequently requested document types for this audience. We provide translations at all attestation levels — certified, sworn, notarised or apostilled — depending on the authority or institution requiring the document. For clients who need confidentiality reassurance, our agency is able to sign a non-disclosure agreement before work begins, giving both individual patients and corporate clients full peace of mind.
