Scientific Translation Services

What are scientific translation services?

Scientific translation services are certified conversions of research papers, patents, clinical study reports, lab records and regulatory dossiers into a target language, produced by bilingual subject-matter experts under an ISO 17100 workflow with a signed certificate of accuracy.

How much do scientific translation services cost in the UK?

Scientific translation in the UK is priced at £0.10–£0.20 per word depending on language pair and subject complexity, with single personal supporting documents from £25, and a 30–50% surcharge for same-day or weekend delivery.

How long does a scientific translation take?

Standard turnaround is 2–3 working days for every document type, single-page or multi-page.

Who translates scientific documents — and what qualifications should they have?

Scientific translations are produced by bilingual subject-matter experts holding a degree or verified professional qualification in the relevant discipline (life sciences, chemistry, physics, engineering, pharmacology or patent law) alongside a recognised translation qualification, then reviewed by a second linguist under ISO 17100.

How do you ensure accuracy under ISO 17100?

Every scientific translation runs a four-stage ISO 17100 workflow: subject-matter translator, second-linguist reviewer, terminology and reference check against journal or regulator style guides, and a signed certificate of accuracy on company letterhead included at no extra cost.

Which scientific disciplines and document types do you cover?

We translate across life sciences, chemistry, physics, engineering, environmental science, computer science, pharmacology and patent law, handling journal articles, theses, grant applications, patents, non-patent literature, clinical study reports, lab reports, MSDS/SDS and regulatory submissions in 150+ languages.

Certified scientific translation for UK researchers, publishers, patent attorneys, biotech and regulatory teams is commissioned from our London office and delivered nationwide under an ISO 17100 workflow, with pricing, turnaround and reviewer profile fixed in writing before work begins.

What are scientific translation services?

Scientific translation services are certified conversions of research papers, patents, clinical study reports, lab records and regulatory dossiers into a target language, produced by bilingual subject-matter experts under an ISO 17100 workflow with a signed certificate of accuracy. The output is fit for peer review, patent prosecution and regulator submission.

Six characteristics separate scientific translation from general document translation:

Which documents count as scientific translation?

Scientific translation covers peer-reviewed articles, conference papers, theses, grant proposals, patents and non-patent literature, clinical study reports, lab notebooks, safety data sheets and regulatory submissions. Each has distinct terminology and formatting constraints.

How does scientific translation differ from technical or medical translation?

Scientific translation prioritises theoretical precision and citation integrity for research audiences. Technical translation prioritises operational accuracy for engineers and end-users. Medical translation prioritises patient safety and regulatory compliance. The three overlap but demand different subject-matter reviewers.

Discipline	Primary audience	Reviewer profile
Scientific	Peer reviewers, patent examiners, grant panels	Bilingual PhD or patent-agent-trained linguist
Technical	Engineers, plant operators, service teams	Bilingual engineering-qualified linguist
Medical	Clinicians, regulators, patients	Clinically qualified linguist plus regulatory reviewer

How much do scientific translation services cost in the UK?

Scientific translation in the UK is priced at £0.10–£0.20 per word depending on language pair and subject complexity. Single personal supporting documents start from £25. Same-day and weekend delivery attract a 30–50% surcharge. Longer projects are quoted individually.

What drives the price of a scientific translation?

Four factors set the price:

1. Language pair rarity — mainstream European pairs sit at the lower end of the £0.10–£0.20 band; Japanese, Korean, Arabic and Nordic pairs sit at the upper end.
2. Subject-matter complexity — patent claims and pharmacology attract senior reviewers; general biology does not.
3. Document length beyond 250 words — very short items are billed as fixed-price documents from £25.
4. Urgency — same-day or weekend delivery adds a 30–50% surcharge.

Indicative price table for common scientific documents

The table below sets out indicative UK pricing for the scientific document types we handle most often. All sit within the £0.10–£0.20 per word band with a 2–3 working-day standard turnaround.

Document	Indicative price	Standard turnaround
Abstract (up to 300 words)	From £25 per document	2 working days
Full research paper	£0.10–£0.20 per word	2–3 working days
Patent claims	£0.15–£0.20 per word	2–3 working days
Clinical study report	£0.12–£0.20 per word	Quoted per corpus
MSDS / SDS	£0.10–£0.18 per word	2–3 working days
Same-day or weekend delivery	+30–50% surcharge	Same working day

Is VAT charged on scientific translation services?

UK VAT applies at the standard rate to scientific translation invoiced to UK-based clients. Overseas academic institutions and B2B customers outside the UK are typically outside the scope, subject to place-of-supply rules. VAT status is confirmed on the written quote before work begins.

How long does a scientific translation take?

Standard turnaround is 2–3 working days for every document type, whether single-page or multi-page. That window applies to the full spectrum of scientific output — peer-reviewed manuscripts, regulatory summaries, patent claims, data tables and supporting appendices alike. Large regulatory dossiers, patent families and systematic-review corpora involve higher word counts and more complex terminology, so these are scoped and quoted individually with a bespoke timeline agreed before work begins.

• Abstract or short scientific letter: typically delivered within 2–3 working days.
• Full research paper up to 8,000 words: 2–3 working days under our standard ISO 17100 workflow, including the second-linguist QC pass.
• Clinical study report or patent family corpus: quoted per project with a milestone schedule.
• Same-day or weekend delivery: available at a 30–50% urgency surcharge, with capacity confirmed at the point of enquiry.

Every job — regardless of turnaround tier — is completed under the same ISO 17100 quality workflow: a subject-matter-qualified linguist translates, a second linguist reviews, and the signed certificate of accuracy is issued at no extra cost. Speed of delivery is never achieved by cutting the quality-assurance stage. Where a deadline is genuinely tight, we allocate a larger translation team to the project rather than compress the review cycle.

Who translates scientific documents — and what qualifications should they have?

Scientific translations are produced by bilingual subject-matter experts holding a degree or verified professional qualification in the relevant discipline — life sciences, chemistry, physics, engineering, pharmacology or patent law — alongside a recognised translation qualification, then reviewed by a second linguist under ISO 17100.

Use this dual-expertise hiring rubric when comparing any provider:

1. Confirm the translator is bilingual to native or near-native level in the target language.
2. Ask for a verifiable domain qualification — a life-sciences degree, patent-agent training, chartered engineer status or clinical-research certification.
3. Ask for a recognised translation qualification (Chartered Institute of Linguists Diploma in Translation, MA in Translation, or equivalent).
4. Ask who performs the second-linguist ISO 17100 review and their domain background.
5. Ask whether patent claims, MDR/IVDR files or pharmacology dossiers trigger a third domain reviewer.
6. Ask for a signed certificate of accuracy and a named point of accountability.

Why does dual expertise (language plus domain) matter more than fluency in scientific translation?

A translator who is fluent but lacks domain training will render 'confidence interval', 'p-value' or 'moiety' as everyday synonyms, breaking scientific meaning. Medical, legal and scientific work must always go to a translator who is bilingual and subject-qualified. Fluency alone reads well and fails peer review.

How we assign a scientific translator to your project

We match by discipline first, then by language pair, then by prior work with the target journal, regulator or patent office — never the other way round. The assignment sequence is:

1. Discipline (e.g. clinical pharmacology, organic chemistry, mechanical engineering, patent claims).
2. Language pair and native direction.
3. Prior work with the target journal, EPO/UK IPO examiner style, or MHRA/EMA templates.
4. Availability against the confirmed deadline.

How do you ensure accuracy under ISO 17100?

Every scientific translation runs a four-stage ISO 17100 workflow: subject-matter translator, second-linguist reviewer, terminology and reference check against journal or regulator style guides, and a signed certificate of accuracy on company letterhead included at no extra cost.

How does the second-linguist QC pass work?

The second linguist re-reads the target against the source line by line. Terminology consistency is checked using a project-specific translation memory. Any conceptual ambiguity is flagged for the original translator before sign-off. The QC pass covers:

When we escalate to a domain reviewer

Patent claims, MDR/IVDR files, clinical protocols, pharmacology dossiers and physics equations trigger a third reviewer with active practice in the field. Even commissioned professional translations have been found lacking when domain reviewers finally check them. The reviewer-in-the-loop QC applies to:

Which scientific disciplines and document types do you cover?

We translate across life sciences, chemistry, physics, engineering, environmental science, computer science, pharmacology and patent law, handling journal articles, theses, grant applications, patents, non-patent literature, clinical study reports, lab reports, MSDS/SDS and regulatory submissions in 150+ languages.

Journal articles, abstracts and conference papers

We translate manuscripts to a journal's house style, handle abstract-only translations for indexing, and match reference formats (Vancouver, APA, IEEE) so peer review is not delayed by editorial rework. Deliverables include clean and tracked-changes versions plus a translator's note on any ambiguous source terminology.

Patents and non-patent literature (NPL)

For UK IPO, EPO and USPTO prosecution we translate patent specifications, claims and non-patent literature (NPL) cited during examination. The workflow mirrors the model the USPTO Scientific and Technical Information Center (STIC) uses when it commissions Patent Human Translations from a vetted translator list. Our NPL workflow covers:

1. Receipt of the cited reference and examiner correspondence.
2. Assignment to a translator with matched discipline and patent-drafting familiarity.
3. Second-linguist QC plus patent-claims reviewer.
4. Signed statement of translator competence delivered with the target text.

Clinical study reports, protocols and lab records

Clinical documentation is translated by translators with pharmacology or clinical-research backgrounds and cross-checked against ICH E6 and MHRA terminology. For full clinical trial documents, patient records and consent forms see Medical Translation.

Safety data sheets, IFUs and regulatory files

MSDS/SDS, instructions for use (IFUs) and MDR/IVDR files are translated by regulatory-trained linguists. For the full engineering and regulatory workflow see Technical Translation.

How does scientific translation support systematic reviews and meta-analyses?

For systematic reviews we translate foreign-language studies flagged during screening — commonly in Japanese, German, Chinese, Russian or Portuguese — so that PRISMA and Cochrane reviews remain methodologically complete and reproducible. Excluding non-English studies from a meta-analysis solely because of language introduces selection bias; our role is to eliminate that gap cleanly, at speed and to a documented quality standard. Turnaround and pricing are agreed per corpus of abstracts and full texts, and our translators hold verified subject-matter qualifications in the relevant discipline — not just linguistic credentials.

Each translator on a systematic-review project is bilingual with a recognised degree or professional accreditation in the scientific domain and a recognised translation qualification, ensuring that technical terms, statistical notation and study-design language are rendered precisely and consistently across a corpus that may run to hundreds of abstracts.

Our systematic-review translation protocol runs in three stages:

1. Triage: a machine-assisted gist read of every flagged abstract allows the review team to confirm eligibility before commissioning full translation — keeping costs proportionate to inclusion probability.
2. Full translation of eligible studies by a discipline-matched linguist under our ISO 17100 workflow, with citation formatting, figure captions and statistical tables preserved in their original structure.
3. Reviewer's declaration of translator competence, so the Cochrane or PRISMA appendix records each translator's qualifications alongside every translated study — meeting editorial and funder requirements without additional administrative burden to the review team.

Because the triage stage uses machine output only for internal eligibility screening — never for the translated text that enters the review — it is entirely consistent with submission standards for high-impact journals and Cochrane editorial policy. Machine output at this stage is gist-level only; it is never published or submitted to a regulator.

Can DeepL or ChatGPT replace a human scientific translator?

DeepL and ChatGPT produce useful first-pass drafts for gist reading but are not fit for peer-reviewed publication, regulator submission or patent prosecution. Nuanced terminology, cited-figure fidelity and legally binding claims still require a certified human translation with ISO 17100 sign-off.

Use case	Machine translation	MTPE	Certified human
Reading an abstract to decide relevance	Fit	Overkill	Overkill
Internal literature scan	Fit	Fit	Overkill
High-volume historical lab archive	Not fit alone	Fit	Overkill for scale
Peer-reviewed publication	Not fit	Not fit	Required
Patent prosecution / NPL	Not fit	Not fit	Required
MHRA / EMA submission	Not fit	Not fit	Required

When is machine translation acceptable as a triage tool?

Machine translation is acceptable for triaging thousands of abstracts to decide which full texts to commission, for internal literature scans and for reading the author's intent before contacting them. It is never acceptable for publication, submission or evidence.

Machine translation with human post-editing (MTPE)

For high-volume, low-risk corpora such as internal lab notebooks or historical archives we offer MTPE — machine output revised by a subject-matter linguist to publishable quality — priced below full human translation. MTPE is inappropriate for peer-review and regulator-facing copy, which is quoted as full human translation.

What does 'medical-grade' translation actually mean for research?

'Medical-grade' is a marketing label for translation performed by a clinically qualified linguist and reviewed by a second domain expert under ISO 17100 — a bar generic providers rarely meet. It matters whenever a mistranslation could affect a clinical or research outcome.

Do you provide certified, notarised, sworn or apostilled scientific translations?

Every scientific translation includes a signed certificate of accuracy at no extra cost. Notarised uplifts are £30–£75 when a UK notary must witness the translator's declaration. Apostille and sworn-before-solicitor options are quoted per document. See our base Certified Translation service, our Notarised Translation Services in the UK workflow, and Sworn Translation Services where a sworn declaration before a solicitor is required.

Tier	What it is	Typical use
Certified	Signed certificate of accuracy on letterhead	Journals, patent offices, universities
Notarised	Notary witnesses the translator's signature	Cross-border submissions, some overseas patent offices
Sworn	Sworn declaration before a solicitor	Court exhibits, contested evidence
Apostilled	FCDO apostille on the notarised translation	Hague Convention overseas use

When do patent offices and journals require certification?

Patent examiners typically require a signed statement of translator competence with NPL translations. Journals rarely require certification. Publishers commissioning translations for open-access repositories increasingly do.

How do free and institutional options compare with paid scientific translation?

Free routes include contacting the paper's original author, using PubMed's linked resources, institutional library translation desks and patent-office non-patent literature services. Each of these is a legitimate starting point for one-off gist reading — understanding the rough content of a foreign-language paper before deciding whether to commission a full translation. However, none of them can deliver certified, deadline-bound output suitable for publication, patent prosecution or regulatory submission, and none carries the ISO 17100 quality assurance that a journal editor, patent office or medicines regulator requires.

Free machine-translation tools are similarly useful for internal triage — a researcher reading a Chinese abstract to assess relevance, for instance — but are not acceptable for publication, patent prosecution or submission to a regulator. That distinction matters: using unreviewed machine output in a filed patent or a regulatory dossier exposes the applicant to validity challenges and compliance risk. The appropriate use of automated tools is gist triage and internal reading only.

• Author contact — free and occasionally fast, but unreliable, unverified, and provides no certificate of accuracy.
• Institutional library desk — variable turnaround, typically no ISO 17100 sign-off, and scope is often limited to staff and students of that institution.
• Free machine-translation tools — acceptable for internal gist reading only; not for publication, patent prosecution or regulatory submission.
• Paid certified route — fixed price from £0.10–£0.20 per word depending on language pair and subject, standard 2–3 working-day turnaround, signed certificate of accuracy at no extra cost, and full ISO 17100 compliance.

The paid certified route is the only option that scales reliably across 150+ languages, meets institutional and regulatory acceptance criteria, and provides a documented audit trail from source file to signed deliverable.

How do you handle confidentiality for unpublished research and patents?

All translators and reviewers sign a project-specific non-disclosure agreement before any file transfer takes place. This is not a blanket platform-level clause — it is a named, project-bound NDA that identifies the specific material, the individuals with access, and the permitted use. For patent families and pre-publication manuscripts, where premature disclosure could compromise a priority date or a journal's embargo, this level of specificity is essential.

• Project-specific NDA signed by every linguist and second-linguist reviewer before work begins.
• UK-hosted encrypted storage operated under UK GDPR and the Data Protection Act 2018 — data does not leave UK jurisdiction without explicit client consent.
• Named project lead accountable for access control and the only point of contact for file transfer and delivery.
• No public machine-translation engines used on confidential material — MT tools that log inputs or use submitted content to train models are never applied to unpublished research or unfiled patents.
• Siloed team allocation — pre-publication and unfiled patent material is restricted to the named team, with no cross-project file sharing.

The prohibition on public machine-translation engines deserves particular emphasis for patent clients. Several widely used tools retain submitted text as training data, which creates a public-disclosure risk that could invalidate novelty claims. Our internal policy is that no confidential scientific material — patent claims, method descriptions, compound data — is processed through any tool that logs or stores inputs. Where machine-translation post-editing is used on non-confidential high-volume corpora, it is performed on a closed, non-logging system overseen by a subject-matter linguist. Confidential projects use human translation exclusively.

How do you get a scientific translation quote in London or the UK?

Send your source files, target language, deadline and intended use to our team and we return a fixed quote within one working hour. Work begins immediately on written acceptance — there is no separate onboarding stage for new clients. Same-day quotes for corpora under 5,000 words are standard, and for larger projects we provide a milestone-based schedule alongside the price. Pricing runs at £0.10–£0.20 per word depending on language pair and subject complexity, with personal supporting documents available from £25 per document. If you need the translation notarised, an uplift of £30–£75 covers the notary witness step on top of the certified translation.

When you submit a quote request it is helpful to indicate the intended use — publication submission, patent prosecution, regulatory dossier, systematic review or certified personal document — because this determines which workflow tier and which quality declaration is attached to the final deliverable. A journal-submission translation requires a different accompanying statement from a notarised regulatory certificate, and flagging the use at the outset means we configure the project correctly from day one.

Do you serve clients outside London?

We serve researchers, publishers, patent agents and regulatory professionals across the UK — including Manchester, Birmingham, Edinburgh, Cardiff, Leeds and the Canary Wharf research corridor. All delivery is digital as standard, with hard-copy courier options available for regulator submissions that require a physical certified document. Our language coverage extends to 150+ languages, so whether the source material is in an EU working language, an Asian research language or a less widely spoken regional language, we can match a subject-matter-qualified translator to your project.

Frequently asked questions

How do I find a translator who actually understands my scientific field, not just the language?

Look for a translator with documented subject-matter qualifications — a degree, postgraduate training, or several years of professional experience in the relevant scientific discipline. A linguist fluent in German but unfamiliar with organic chemistry will struggle with nomenclature, reaction mechanisms and units that a specialist handles automatically. At ISO 17100-compliant agencies, every job is also reviewed by a second linguist, adding a further layer of subject accuracy. Ask the provider to confirm the translator's specific field before accepting the project.

Will LLMs/AI like ChatGPT fully replace human scientific translators?

No — AI tools currently cannot fully replace human scientific translators for high-stakes content. Large language models generate fluent-sounding text but regularly mishandle specialised terminology, unit conventions, chemical nomenclature and statistical notation. Errors can be subtle and hard to detect without domain expertise. For published research, regulatory submissions or patent documents, the consequences of mistranslation are significant, which is why ISO 17100 standards require a qualified human translator plus an independent review step. AI can accelerate drafts, but human expert oversight remains essential.

What's the difference between 'medical-grade' translation and regular translation — and does it matter for research?

Medical-grade translation requires translators with verified biomedical or clinical qualifications and adherence to strict quality processes such as ISO 17100. Regular translation applies no such domain requirement, so a general linguist may handle content without specialist knowledge of pharmacology, clinical trial protocols or device regulations. For research — especially submissions to regulators, ethics committees or peer-reviewed journals — accuracy of terminology, dosing units and statistical language is critical. A mistranslated endpoint description or safety signal can invalidate a study or create a patient-safety issue.

Is DeepL or ChatGPT good enough for translating a scientific paper, or do I need a human?

For a quick personal reference read, machine translation tools like DeepL or ChatGPT are often adequate — but they are not reliable enough for publication, submission or regulatory use. Both systems produce errors in specialised terminology, miss context-dependent meanings and occasionally omit or invent content. Scientific papers contain precise numerical data, units, statistical language and field-specific nomenclature where a single mistranslation can change the meaning of a finding. A human translator with subject-matter expertise, ideally working under an ISO 17100 process with a second-linguist review, is required for any formal purpose.

What qualifications should a scientific or medical translator actually have?

A scientific or medical translator should hold a relevant degree or postgraduate qualification in both translation and the subject discipline — for example, a life sciences degree combined with a translation qualification such as a Diploma from the Chartered Institute of Linguists (CIOL). Membership of professional bodies like CIOL or the Institute of Translation and Interpreting (ITI) signals ongoing CPD and adherence to a code of ethics. Under ISO 17100, agencies must verify translators' credentials and subject-matter competence before assignment, and every translation should be reviewed by a second qualified linguist.

What is the scientific translation?

Scientific translation is the specialised conversion of scientific, technical or research content from one language into another while preserving precise meaning, terminology and formatting. It covers academic papers, clinical trial documents, laboratory protocols, regulatory submissions, patents and research grant applications. Unlike general translation, it demands that the translator understand the underlying subject matter — biology, chemistry, physics, medicine and so on — not just the language. Errors in units, nomenclature or statistical language can invalidate results or mislead readers, which is why subject-qualified translators and quality review processes are standard.

How much does a certified translation cost in the UK?

Certified translation in the UK typically costs £0.10–£0.20 per word, depending on the language pair and subject matter. Short personal certificates — such as birth, marriage or death certificates, diplomas, passports and IDs — are usually quoted at a fixed price per document, starting from £25. A signed certificate of accuracy is included at no extra cost. Urgent same-day or weekend delivery is available at a 30–50% surcharge over the standard rate. Large technical, legal or regulatory projects are quoted individually after review.

Can I do my own certified translation?

No — you cannot certify your own translation of a document that relates to you. UK authorities such as the Home Office, HM Passport Office, courts and universities require a translation certified by an independent, qualified third party who can attest that the translation is accurate and complete. The certifier must sign a statement of accuracy and provide their contact details. Attempting to self-certify is routinely rejected. You should use a professional translation provider that issues a signed certificate of accuracy with every job.

Who can certify a translation in the UK?

In the UK, a certified translation must be produced and signed by a competent, independent translator or translation company — not the document's owner. There is no single statutory body that licenses translators, but accepted certifiers include professional translators who are members of recognised bodies such as the Chartered Institute of Linguists (CIOL) or the Institute of Translation and Interpreting (ITI), and agencies working to ISO 17100 standards. The certification takes the form of a signed statement of accuracy accompanying the translation. Most UK authorities, including the Home Office and courts, accept this format.

How do you know if a translator is certified?

In the UK, there is no single government-issued 'certified translator' licence, so you should look for verifiable professional credentials. Check whether the translator or agency holds membership of recognised bodies such as the Chartered Institute of Linguists (CIOL) or the Institute of Translation and Interpreting (ITI), or operates under ISO 17100 — an internationally recognised quality standard requiring qualified translators and a mandatory second-linguist review. A legitimate provider will supply a signed certificate of accuracy with every translation and be willing to share their accreditation details on request.
