Our services
What are document translation services for businesses?
Document translation services for businesses are managed language services that convert corporate documents — contracts, financial reports, HR records, patents, and marketing content — between languages under a defined quality standard such as ISO 17100, with optional certified, sworn, or notarised output for legal or regulatory use.
Which business documents most need professional translation?
The most translated business documents fall into six categories: legal contracts, financial statements, HR and immigration files, technical manuals, marketing collateral, and regulatory submissions — each mapped to a specific certification tier under UK conventions.
What is the difference between certified, sworn, notarised, and apostilled translations?
Certified translations carry a signed statement of accuracy from the agency; sworn translations are produced by a court-authorised translator in civil-law jurisdictions; notarised translations add a notary’s signature verification; apostilled translations are further legalised for use abroad under the Hague Convention.
How much do business document translation services cost in the UK?
UK business document translation costs start from £30 per page under ISO 17100, with per-word rates typical for volume projects, and total price driven by language pair, subject specialism, certification tier, turnaround urgency, and DTP requirements.
How fast can business documents be translated?
Business documents are delivered same-day for civil documents under 1,000 words placed London before 11:00 GMT, within 24 to 48 hours for legal and academic packs, and on agreed milestones for technical projects above 10,000 words, all under ISO 17100 quality control.
How does a professional translation workflow work under ISO 17100?
An ISO 17100 workflow follows six defined steps: source analysis, translation by a qualified linguist, revision by a second qualified linguist, terminology QA, client review, and controlled delivery — with named credentials, version control, and audit logs retained for every project.
UK businesses procuring translation face a compliance decision, not a language purchase — the vendor’s certification stack, turnaround commitment, and data-handling controls determine whether the output survives Home Office scrutiny, court submission, or audit review. This guide, part of our broader Translation Services in London and the UK hub, maps document types to certification tiers, publishes concrete GBP pricing, and details the ISO 17100 workflow procurement teams need to verify.
What are document translation services for businesses?
Document translation services for businesses are managed language services that convert corporate documents — contracts, financial reports, HR records, patents, and marketing content — between languages under a defined quality standard such as ISO 17100, with optional certified, sworn, or notarised output for legal or regulatory use. The service sits within a procurement contract, not a freelance transaction, and delivers auditable outputs against written SLAs.
The service covers six operating pillars:
- Quality standard — ISO 17100 for human translation, ISO 18587 for machine translation post-editing.
- Certification tier — certified, sworn, notarised, or apostilled depending on receiving authority.
- Confidentiality — signed NDA with every linguist, encrypted transfer, GDPR and UK Data Protection Act 2018 alignment.
- Turnaround — same-day, 24–48 hours, or milestone delivery based on document class.
- Pricing — per page or per word in GBP, transparent GBP quote before work starts.
- Language coverage — 200+ pairs with native-market linguists.
How do business document translation services differ from consumer translation?
Business document translation differs from consumer translation four attributes: contractual NDAs, audit-ready certification, defined turnaround SLAs, and terminology management across recurring projects rather than one-off personal documents. Business projects are procured against a data processing agreement, delivered under an ISO-defined workflow, and supported by translation memory that keeps terminology consistent across quarterly reporting cycles, product releases, and multi-year contract families.
Which document formats are supported?
Supported formats include DOCX, PDF, XLSX, PPTX, InDesign (IDML), XLIFF, HTML, and subtitle files such as SRT and VTT, with layout preserved through DTP where required. Editable source files reduce cost; scanned PDFs incur OCR handling. For audiovisual assets requiring SRT and VTT output, see our Subtitle Translation Services in London.
Which business documents most need professional translation?
The most translated business documents fall into six categories: legal contracts, financial statements, HR and immigration files, technical manuals, marketing collateral, and regulatory submissions — each mapped to a specific certification tier under UK conventions. The table below summarises the mapping procurement teams need before requesting a quote.
| Document type | Category | Typical UK certification tier |
|---|---|---|
| Commercial contract, MSA, NDA | Legal | Certified (ISO 17100 agency statement) |
| Share purchase agreement, court filing | Legal | Certified; sworn if foreign court receives |
| Power of attorney, corporate resolution | Legal | Notarised or apostilled for overseas use |
| Annual report, audited accounts | Financial | Certified |
| Board minutes, tax filing, KYC pack | Financial | Certified |
| Employment contract, disciplinary record | HR | Certified |
| Right-to-work, sponsor licence evidence | Immigration | Certified for UKVI |
| Birth, marriage, degree certificate | Civil (HR/immigration) | Certified for Home Office; sworn if overseas |
| Patent specification | Technical/legal | Certified; sworn for foreign patent office |
| Technical manual, SOP | Technical | Standard ISO 17100 (no certification) |
| Marketing collateral, website copy | Marketing | Standard ISO 17100 with transcreation |
| Regulatory submission (MHRA, EMA) | Regulatory | Certified; specialist reviewer required |
What legal documents require certified or sworn translation?
Legal documents requiring certified or sworn translation include commercial contracts, MSAs, NDAs, share purchase agreements, court filings, powers of attorney, and corporate resolutions submitted to UK courts, Companies House, or foreign registries. For UK-facing submissions, a certified translation from an ISO 17100 agency is accepted; for civil-law jurisdictions such as Spain, France, Italy, and Germany, a sworn translator authorised by that country’s court is required, because the European legislator has not harmonised the status of official translators, leaving the profession governed by national codes. Business contract translation services routinely combine both tiers within a single deal pack.
How are financial and audit documents translated?
Financial and audit documents — annual reports, audited accounts, board minutes, tax filings, and KYC packs — are translated by specialists in IFRS and UK GAAP terminology, with numerical formats localised to comma and decimal conventions of the target market. Financial statement translation services apply CAT-tool glossaries locked to the client’s accounting policy manual, so line items reconcile across successive reporting periods without drift.
What HR and immigration documents need translation?
HR and immigration documents needing translation include employment contracts, sponsor licence evidence, right-to-work documents, disciplinary records, and civil status documents (birth, marriage, degree certificates) required for Home Office and Skilled Worker visa submissions. Every file in this class contains personal data, so processing runs under a signed data processing addendum with UK Data Protection Act 2018 controls.
How are technical manuals and patents translated?
Technical manuals and patents are translated by subject-specialist linguists using CAT tools and client-approved glossaries, then reviewed by a second qualified translator under ISO 17100, with milestone delivery for projects above 10,000 words. A professional translator produces 2,000 to 3,000 words per day of finished, revised output, so a 30,000-word manual runs on a two-to-three-week schedule with weekly milestone deliveries. For engineering, software, and life-sciences content, see our Expert Technical Translation Services in London.
What is the difference between certified, sworn, notarised, and apostilled translations?
Certified translations carry a signed statement of accuracy from the agency; sworn translations are produced by a court-authorised translator in civil-law jurisdictions; notarised translations add a notary’s signature verification; apostilled translations are further legalised for use abroad under the Hague Convention. Selecting the wrong tier causes rejection at the receiving authority and forces a full rework at the client’s cost.
| Tier | What it adds | Who issues it | Typical UK use case |
|---|---|---|---|
| Certified | Signed accuracy statement | ISO 17100 agency | Home Office, UKVI, HMRC, Companies House, UK courts, universities |
| Sworn | Legal authority of a court-appointed translator | Sworn translator (civil-law country) | Documents for Spain, France, Italy, Germany |
| Notarised | Notary confirms translator’s identity and signature (not accuracy) | Notary public | Overseas corporate filings, some embassy submissions |
| Apostilled | Hague Convention legalisation for cross-border use | FCDO Legalisation Office (UK) | Public documents used in Hague signatory states |
The 1961 Hague Apostille Convention replaced traditional consular legalisation with a single apostille certificate accepted across signatory states, which is why apostille — not full legalisation — is the correct route for most cross-border corporate use.
When does a UK business need a certified translation?
A UK business needs a certified translation when submitting foreign-language documents to the Home Office, UK courts, Companies House, UKVI, HMRC, or universities — bodies that accept an ISO 17100 agency’s signed certificate of accuracy without notary involvement. The certificate names the agency, the translator, the source and target languages, and confirms the translation is a true and accurate rendering. For remote-issued packs delivered by secure PDF, see our Online Certified Translation Services in the UK.
When is a sworn or notarised translation required?
A sworn or notarised translation is required when the receiving authority sits in a civil-law jurisdiction (Spain, France, Italy, Germany) or when a foreign court, embassy, or notary explicitly demands an additional layer of witnessed authentication beyond agency certification. Notarisation validates the translator’s signature, not the translation’s linguistic accuracy — accuracy remains attested by the translator’s signed statement, while the notary confirms the signature was made by the identified person.
Pricing
How much do business document translation services cost in the UK?
UK business document translation costs start from £30 per page under ISO 17100, with per-word rates typical for volume projects, and total price driven by language pair, subject specialism, certification tier, turnaround urgency, and DTP requirements. Two worked examples anchor the ranges procurement should expect.
| Project | Pricing basis | Indicative GBP total | Delivery |
|---|---|---|---|
| 50-page contract pack, English → French, certified | Per page (£30 baseline, legal specialism uplift) | £1,800–£2,400 | 4–5 business days |
| 10,000-word technical manual, English → German | Per word with volume discount | £1,000–£1,600 | 2 weeks, milestone delivery |
| Single civil certificate (birth, marriage), certified | Per page | £30–£45 | Same day (before 11:00 GMT) |
| Rush surcharge, 24-hour turnaround | 25–50% uplift on base rate | Applied to line total | 24 hours |
What drives the price of a business translation quote?
Five variables drive a business translation quote: source word count, language pair rarity, subject-matter specialism, certification tier, and turnaround window — with same-day and rare-pair projects priced at a premium. Highly specialised legal, medical, and patent content commands 50–100% more than general business copy, reflecting the subject-matter expertise, precision, and standards compliance the content demands. Rare pairs such as English to Swahili, Amharic, or Pashto price higher than English to Spanish or French because the qualified-translator pool is smaller.
How is a 10,000-word project priced?
A 10,000-word technical translation is Quoted per word with volume discount, delivered on agreed milestones under ISO 17100, and priced against three variables — subject specialism, language pair, and DTP scope — rather than a flat per-page rate. For a general-technical English → German manual, the finished budget sits between £1,000 and £1,600 in GBP, with the second-linguist revision, terminology QA, and controlled delivery included in the line price.
How fast can business documents be translated?
Turnaround for business document translation is governed by document type, word count, and certification tier — and every SLA is fixed in writing at quote stage, never left to best effort. Civil documents under 1,000 words placed before 11:00 GMT qualify for same-day delivery; legal and academic packs are completed within 24 to 48 hours; and large technical projects above 10,000 words are handled under a structured milestone schedule. The entire workflow conforms to ISO 17100 quality control, meaning a second linguist revises every translation before it leaves the desk — speed is never traded for accuracy.
- Same-day. Civil documents (birth certificates, marriage certificates, degree certificates) under 1,000 words, placed before 11:00 GMT — delivered by close of business the same day. This tier is available across all 200+ supported languages where a native-speaker linguist is on shift.
- 24–48 hours. Legal packs, academic transcripts, certified HR files, and standard corporate documents up to 5,000 words. The 24–48 hour window accommodates the mandatory second-linguist revision required under ISO 17100 without compressing quality checks.
- 3–7 business days. Financial reports, KYC packs, audited accounts, and mid-size legal deal folders in the 5,000–15,000-word range. This bracket also covers most NDA and MSA packages requiring certified output accepted by UK courts or Companies House.
- Milestone delivery. Technical manuals, patent portfolios, and regulatory submissions above 10,000 words are split into weekly deliverables tied to a 2,000–3,000-word-per-translator-per-day production rate. Each milestone is reviewed and approved before the next begins, keeping large projects on track and reviewable in stages.
- Rush tier. A 25–50% surcharge applies to compressed windows that require evening or weekend work. Rush requests must still clear all ISO 17100 quality steps — the surcharge funds additional linguist resourcing, not a bypass of revision.
Deadlines for notarised or apostilled output carry additional lead time because a notary appointment is required after translation is complete. Projects needing Hague Convention apostille legalisation for cross-border use of public documents should factor in at least one to two additional business days beyond the core translation SLA.
How it works
How does a professional translation workflow work under ISO 17100?
1
What is ISO 17100 and why does it matter for procurement?
ISO 17100 is the international standard for translation services that specifies translator qualifications, mandatory two-linguist revision, project-management processes, and record-keeping — giving procurement a documented, auditable baseline rather than a vendor’s self-declared quality claim. A vendor claiming “ISO 17100 quality” without a valid certificate is making a marketing statement; a certified agency can produce its certificate, audit scope, and named revisers on request.
2
How does ISO 18587 apply to machine translation post-editing?
ISO 18587 governs full human post-editing of machine translation output, requiring a qualified post-editor to bring raw MT to a quality comparable with human translation — relevant when vendors offer discounted MTPE tiers for high-volume, low-risk content. Procurement should confirm which content classes are eligible for MTPE (typically internal knowledge bases, product catalogues, support articles) and which remain in the ISO 17100 human-only lane (contracts, regulatory filings, marketing copy).
About
How is confidentiality handled under GDPR and UK Data Protection Act 2018?
Confidentiality is handled through signed NDAs with every linguist, encrypted file transfer, restricted access, GDPR-compliant processing agreements, and UK Data Protection Act 2018 controls — with data-processing addenda available for clients handling personal, financial, or medical data. The following checklist applies to any pack containing personal data — HR files, medical records, KYC documents:
- Data Processing Agreement (DPA). Signed before source files are transferred, naming lawful basis and processing purposes.
- Encrypted transfer. Files exchanged through a TLS-secured portal, not email attachments.
- Named-linguist NDA. Each translator and reviser handling the file is bound by an individual NDA on record.
- Access control. Role-based access, with logs retained for audit.
- Retention and deletion. Defined retention window (typically 30–90 days post-delivery) with certified deletion on request.
- Sub-processor register. Any external processor disclosed in writing, with equivalent controls flowed down.
- Breach notification. Contractual commitment to notify the client within 24 hours of any suspected incident, supporting the client’s 72-hour ICO obligation.
How do you choose a business document translation provider?
Choose a business document translation provider on six criteria: ISO 17100 certification, subject-matter specialism, published turnaround SLAs, transparent GBP pricing, GDPR-compliant workflow, and named revision policy — verified against sample work and references rather than marketing claims. Test each criterion against evidence, not brochure copy.
- ISO 17100 certificate. Request the current certificate and the audit scope.
- Subject specialism. Ask for translator CVs and past project references in the client’s domain.
- Turnaround SLA in writing. Confirmed deadline on the quote, with defined remedy for late delivery.
- Transparent GBP pricing. Line-item quote showing base rate, certification, DTP, and any rush uplift.
- GDPR workflow. DPA, encrypted portal, sub-processor list, retention policy.
- Revision and rework policy. Named second linguist, defined rework window, no-charge correction of legitimate errors.
What questions should procurement ask a translation vendor?
Procurement should ask five questions: which ISO standards are held, who performs the second-linguist revision, what the rework policy is, how personal data is stored and deleted, and what the confirmed turnaround is in writing for the specific document pack.
- Q: Which ISO certifications does your agency hold, and what is the audit scope?
A: ISO 17100 for human translation and ISO 18587 for MTPE, with the certificate naming the services and languages in scope. - Q: Who performs the second-linguist revision, and what are their credentials?
A: A qualified reviser, separate from the translator, meeting ISO 17100 qualification criteria — CV and reference available. - Q: What is your rework policy if the client rejects the delivery?
A: A defined review window (typically 14 days) during which any legitimate errors are corrected at no additional cost. - Q: How is personal data stored during and after the project, and when is it deleted?
A: Encrypted portal storage, role-based access, and certified deletion within the agreed retention window (30–90 days). - Q: What is the confirmed turnaround in writing for our specific pack?
A: A named deadline on the quote — same-day, 24–48 hours, or milestone schedule — with defined remedy for missed dates.
Which languages are covered by business document translation?
Professional business document translation is available across 200+ languages, giving UK businesses a single provider for every market they operate in. The service covers all high-demand European and global business languages — French, German, Spanish, Italian, Polish, Arabic, Mandarin Chinese, Korean, Japanese, and Portuguese — as well as a broad range of less-commonly-requested languages including Vietnamese, Amharic, Farsi, Ukrainian, and Swahili. Every language pair is handled by a native-speaker linguist resident in, or deeply familiar with, the target market, ensuring that register, legal terminology, and cultural conventions are accurate from the first draft.
Language coverage is not uniform in quality across providers, so it is worth confirming that your specific pair is supported at the certification tier you need. Our network maintains native-speaker linguists across all 200+ languages at ISO 17100 standard — meaning source analysis, translation, and independent revision by a second linguist are available regardless of whether the target language is French or Amharic. For civil-law jurisdictions such as Spain, France, Italy, and Germany, sworn translation is a legal requirement, and sworn-qualified linguists are held on roster for each of those languages. For documents destined for UK bodies — the Home Office, UKVI, HMRC, Companies House, UK courts, or universities — certified translation output is available in every supported language pair.
Specialist language-specific workflows are also maintained for pairs where formatting, script direction, or character-set handling requires additional technical steps, such as Arabic (right-to-left), Mandarin Chinese, Japanese, and Korean. Terminology glossaries and translation memories are managed per language pair and per client, so consistency is preserved across recurring projects and volume discounts apply as your translation memory grows.
How do you request a quote for business document translation?
Requesting a quote is a structured, six-step process designed to return a fixed GBP price and a confirmed SLA — within one business hour for standard packs. Because pricing starts from £30 per page and scales with word count, language pair, and certification tier, providing accurate source files and complete project details at the outset is the fastest route to an actionable quote. Every quote is line-itemised so you can see exactly what each element costs before approving work to begin.
- Upload source files. Submit documents in any standard format — DOCX, PDF, XLSX, PPTX, IDML, XLIFF, HTML, SRT, or VTT — through the encrypted secure portal. File transfer is encrypted in transit and at rest, satisfying the GDPR and UK Data Protection Act 2018 requirements for personal data handling.
- Specify target languages. Select one or multiple targets from the 200+ supported language pairs, including French, German, Spanish, Polish, Arabic, Mandarin, Korean, and Japanese. Multi-language projects are quoted as a single consolidated package.
- Select certification tier. Choose from standard ISO 17100, certified (accepted by the Home Office, UKVI, HMRC, Companies House, UK courts, and universities), sworn (required for civil-law jurisdictions such as Spain, France, Italy, and Germany), notarised (certified translation plus notary signature verification), or apostilled (Hague Convention legalisation for cross-border use of public documents).
- Set the deadline. Indicate whether you need same-day delivery (civil documents under 1,000 words placed before 11:00 GMT), a 24–48-hour turnaround (legal and academic packs), or a milestone schedule for projects above 10,000 words. Rush requests involving evening or weekend work are flagged here so the surcharge is visible in the quote.
- Sign the Data Processing Agreement. A DPA is required for any pack containing personal data — this agreement, combined with NDA obligations on all linguists and encrypted file transfer, keeps the project fully GDPR-compliant and aligned with UK Data Protection Act 2018 requirements.
- Approve the fixed GBP quote. Once you confirm the quote in writing, work begins immediately. The SLA clock starts from written approval, and milestone projects receive a delivery schedule with agreed checkpoint dates so progress is always visible.
For repeat clients, translation memories and terminology glossaries built on previous projects are applied automatically, which reduces both per-word cost and review time on recurring document types such as contracts, NDAs, HR files, and annual reports.
