What is certified Cantonese document translation?
Certified Cantonese document translation is a translation signed and stamped by an ISO 17100 agency, accepted by the Home Office, UKVI, HMCTS courts, and UK universities for personal and legal documents from Hong Kong and Macau. Every certificate carries the translator’s name, signature, date, agency stamp, and a statement of accuracy that meets UK evidential requirements.
When do you need sworn or notarised Cantonese translation?
Sworn or notarised Cantonese translation is required when an overseas authority demands a translator’s affidavit or a UK notary public seal in addition to certification. Common triggers include Hong Kong court filings, Macau notarial deeds, foreign embassy submissions, and apostille requests for the 120+ Hague Convention countries.
What does Cantonese interpreting cover (in-person, telephone, video)?
Cantonese interpreting covers four modes: consecutive interpreting for meetings and courts, simultaneous interpreting for conferences, telephone interpreting for remote consultations, and Zoom or Teams video remote interpreting. Hong Kong-trained interpreters work across London, Manchester, Birmingham, and the wider UK for legal, medical, corporate, and government bookings.
Do you provide Cantonese subtitling, voice-over, and transcription?
Yes — Cantonese subtitling, voice-over, and transcription convert video, audio, and broadcast content into Traditional Chinese subtitles or native Cantonese voice-over for marketing, e-learning, and broadcast clients. Deliverables include SRT and VTT subtitle files, broadcast-grade MP3/WAV voice-over recordings, and time-coded transcripts.
Which Cantonese documents are translated most often?
We translate 12 Cantonese document types most often: HKID cards, HKSAR passports, Hong Kong birth and marriage certificates, Macau police records, academic diplomas, bank statements, contracts, court judgments, patents, marketing materials, websites, and medical reports. Every document is handled by a native Cantonese linguist working under the ISO 17100 translator-plus-reviser workflow, which mandates an independent second reviewer on every translation — ensuring the certified output meets the evidential standards required by UK authorities.
| Category | Document types | Typical recipient |
|---|---|---|
| Personal civil | HKID card, HKSAR passport, Hong Kong birth certificate, Hong Kong marriage certificate | UKVI, Home Office, GRO |
| Background | Hong Kong police clearance, Macau police record, Certificate of No Criminal Conviction | UKVI, employers, regulators |
| Academic | HKDSE certificate, university diploma, transcripts, reference letters | UK ENIC, universities, GMC |
| Legal | Contracts, witness statements, Hong Kong court judgments, wills, powers of attorney | HMCTS, solicitors, notaries |
| Business and technical | Financial statements, patents, manuals, websites, e-commerce listings | Corporates, IPO, agencies |
| Medical | Hospital records, consent forms, prescriptions, clinical reports | NHS, GMC, insurers |
Which Cantonese personal documents do UK visa and Home Office applications need?
UK visa and Home Office applications most often need certified Cantonese translations of Hong Kong birth certificates, marriage certificates, HKSAR passports, HKID cards, and Hong Kong or Macau police clearance records, each accepted under UKVI evidential standards. UKVI requires a certified English translation for any document not in English or Welsh, and that translation must carry a statement of accuracy, the translator’s name, signature, contact details, and the date of translation. The Home Office accepts certified Cantonese-to-English translations produced by an ISO 17100 agency for visa, settlement, and citizenship applications. Because Hong Kong recognises Cantonese, English, and Standard Written Chinese as official languages under the HKSAR Basic Law, source documents appear in any of those languages — and our translators handle all combinations. See our Visa Certificate Translation and Background Check Certificate Translation pages for the full UKVI workflow.
Which Cantonese legal documents do UK courts and solicitors require?
UK courts and solicitors require certified Cantonese translations of contracts, witness statements, Hong Kong court judgments, powers of attorney, wills, and corporate filings, delivered with a translator certification statement and same-day options available for litigation deadlines. HMCTS evidential standards demand that translations are accurate, complete, and certified — criteria our ISO 17100 process is specifically structured to satisfy. Our Legal Translation Services in London and the UK page details courtroom procedure, sworn affidavits, and HMCTS requirements in full.
Which Cantonese academic documents do UK universities and NARIC/ENIC accept?
UK universities and UK ENIC accept certified Cantonese translations of HKDSE certificates, university diplomas, academic transcripts, and reference letters, provided the translation is issued by an ISO 17100 agency and accompanied by a certification statement. That statement names the translator, references the agency’s ISO 17100 accreditation, and confirms that the translation is accurate and complete to the best of the translator’s knowledge. Hong Kong’s own academic documents are written in Traditional Chinese characters — the same script used across Hong Kong, Macau, and the UK Cantonese diaspora — so correct script identification is essential before translation begins.
Which Cantonese business and technical documents can be translated?
We translate Cantonese business and technical documents including company contracts, financial statements, patents, product manuals, e-commerce listings, marketing campaigns, and websites, with sector-specialist translators experienced in finance, legal, life sciences, and technology terminology. All client files are handled under ISO 27001-aligned information-security procedures, which govern the confidentiality of every document we receive. Patent files route through our Patent Translation Services in London and the UK team for IP-grade terminology control.

What is the per-word rate for Cantonese business translation?
The per-word rate for Cantonese business translation is £0.12–£0.18 per source word, varying by subject complexity, file format, and whether the project involves Traditional Chinese desktop publishing or transcreation. Patents, clinical trials, and structured financial reports sit at the upper band; standard corporate correspondence sits at the lower band.
What is the per-page rate for certified Cantonese document translation?
The per-page rate for certified Cantonese document translation is £35–£60 per page for standard civil documents such as birth, marriage, and police certificates, with a per-page minimum that includes certification, stamp, and PDF delivery. A “page” means an A4-equivalent source page with up to roughly 250 words.
What surcharges apply for sworn, notarised, or same-day Cantonese translation?
Three surcharges apply on top of the base rate:
- Notarisation by a UK notary public adds a fixed notary fee per document.
- Sworn affidavit adds a translator’s declaration fee for sworn statements before a commissioner for oaths.
- Same-day turnaround adds a 25–50% rush premium based on word count and delivery deadline.
How fast is same-day Cantonese translation turnaround?
Same-day Cantonese translation turnaround delivers certified documents under 1,000 words within the same UK business day when booked before 11am, with an overnight tier for projects up to 3,000 words and a scheduled SLA for larger volumes. Because Cantonese documents use Traditional Chinese characters — a script that is visually and structurally distinct from Simplified Chinese — our production workflow assigns only native Cantonese linguists, preventing the script-confusion errors that arise when Mandarin translators handle Hong Kong or Macau source files. Each rush job still passes through the full ISO 17100 two-stage process: a native translator drafts the translation and an independent reviser checks it before the project manager authorises delivery.
- Booking cutoff: Files received before 11am UK time enter same-day production immediately.
- Production window: A native Cantonese translator drafts the text, a second independent reviser checks accuracy and terminology, and a project manager signs off — all within the same business day.
- Delivery window: A stamped, certified PDF is emailed by 5pm UK time; a hard copy is dispatched by next-day tracked courier where required.
- Overnight tier: Documents up to 3,000 words are returned by 9am the next UK business day, complete with certification statement, translator name, signature, and date.
- Scheduled SLA: Volumes above 3,000 words receive a fixed-date delivery schedule confirmed in writing at the point of quote approval, with no hidden surcharges.
Rush turnaround does not compromise certification quality. Every same-day output carries the translator’s name, signature, date, and a statement of accuracy — satisfying UKVI, Home Office, and HMCTS requirements in full, regardless of the speed tier selected.
How is Cantonese translation quality ensured (ISO 17100)?
We ensure Cantonese translation quality through ISO 17100 certification, which mandates a native Cantonese translator, a second independent reviser, and a project manager review, supported by ISO 27001 information-security controls for confidential client files. ISO 17100:2015 is the international standard governing translator qualifications and the translate–revise–review process.
- Step 1 — Native Cantonese translator drafts the target text into their mother tongue.
- Step 2 — Independent second reviser compares source and target line by line for accuracy, terminology, and register.
- Step 3 — Cantonese-speaking project manager performs the final quality check, applies the certification statement, and releases the file.
- Step 4 — ISO 27001 controls govern encrypted file transfer, NDA coverage, and UK GDPR-compliant data retention.
Who are the Cantonese translators behind your projects?
Our Cantonese translators are native Cantonese speakers from Hong Kong, Macau, and Guangdong, hold linguistic qualifications, have 5+ years of post-qualification experience, and translate only into their mother tongue per ISO 17100 article 3.1.4. Sector specialists hold additional qualifications in law, medicine, finance, or engineering.
How do you handle Traditional Chinese characters and Cantonese register?
We handle Traditional Chinese characters and Cantonese register by matching the target audience: formal Standard Written Chinese for legal and corporate documents, colloquial spoken Cantonese for subtitles and voice-over, and Hong Kong-style or Macau-style spelling conventions for proper nouns. Hong Kong registers prefer Hong Kong-specific terminology and place names; Macau registers reflect Portuguese-influenced naming; UK diaspora content blends Hong Kong conventions with British English source references.
Which industries do Cantonese translators specialise in?
Our Cantonese translators specialise eight industries: legal, banking and finance, life sciences, marketing and PR, e-commerce, technology and patents, travel and hospitality, and government. Each linguist is matched to the sector in which they hold subject-matter expertise, and all work exclusively between Cantonese — written in Traditional Chinese characters — and English. This script specialism is critical: Cantonese documents from Hong Kong and Macau are always in Traditional Chinese, and using a translator trained only in Simplified Chinese produces terminology mismatches that can cause applications to be rejected. Every translation is produced under the ISO 17100 native-translator-plus-independent-reviser workflow, so sector accuracy is verified at two independent stages before delivery.
- Legal: contracts, court judgments, witness statements, Hong Kong probate, powers of attorney, and HMCTS-bound certified translations.
- Banking and finance: annual reports, IPO prospectuses, HKEX filings, KYC documents, and regulatory disclosures — handled by linguists familiar with both Hong Kong and UK financial frameworks.
- Life sciences: clinical trial protocols, patient information sheets, MHRA submissions, and medical device documentation requiring precise bilingual terminology.
- Marketing and PR: transcreation of slogans, brand voice adaptation, and campaign copy through our Marketing Translation Services in London and the UK team — including content targeting the sizeable UK Cantonese-speaking diaspora community.
- E-commerce: product listings, platform store content, and customer support copy optimised for Cantonese-speaking consumers in Hong Kong and the UK.
- Technology and patents: software UI strings, technical manuals, and IP filings where precise terminology directly affects legal protection.
- Travel and hospitality: hotel collateral, visitor guides, and tourism board content in both Cantonese and English.
- Government: public information notices, consular materials, official correspondence, and documents destined for Home Office or UKVI review.

What are the key facts about the Cantonese language: script, speakers, and dialects?
Cantonese is spoken by approximately 85 million native speakers worldwide, uses Traditional Chinese characters, and differs from Mandarin in tones, vocabulary, grammar, and written script. For any UK business or individual commissioning a translation, understanding these distinctions is essential: sending a Cantonese document to a Mandarin translator — or assuming Simplified Chinese output will satisfy a Hong Kong authority — will produce a translation that is both linguistically incorrect and procedurally unacceptable.
- Speakers worldwide: Approximately 85 million native speakers, concentrated primarily in Hong Kong, Macau, the Guangdong province of southern China, and Cantonese diaspora communities across the UK, North America, Australia, and Southeast Asia.
- Script: Cantonese is written in Traditional Chinese characters — the standard script in Hong Kong, Macau, and the global Cantonese diaspora. Mandarin, by contrast, is the official spoken Chinese of mainland China and uses Simplified Chinese characters; the two scripts are not interchangeable in translation.
- Cantonese vs Mandarin: Cantonese is a spoken Chinese dialect with its own distinct tonal system, vocabulary, and grammar, written in Traditional Chinese; Mandarin is the official national language of mainland China, spoken with four tones and written in Simplified Chinese. Selecting the correct language pair — and the correct script — is the first decision in any Chinese translation project.
- Hong Kong official languages: Under the HKSAR Basic Law, Hong Kong’s official languages are Cantonese, English, and Standard Written Chinese — which means official Hong Kong documents carry text in any or all of these languages.
- Macau official languages: Macau’s official languages are Cantonese and Portuguese, with Traditional Chinese as the standard written script for Chinese-language documents — a combination that requires translators with specific Macau legal and administrative terminology.
- Tonal system: Hong Kong Cantonese uses six contrastive tones, compared with four in Mandarin, producing fundamentally different pronunciation patterns and making the two languages mutually unintelligible in speech.
- UK diaspora: The Cantonese-speaking community in the UK numbers well over 150,000 people, distributed across London, Manchester, Birmingham, and Liverpool — making Cantonese one of the most widely spoken Chinese varieties in the country and a commercially significant language for UK businesses targeting this audience.
- Cultural register: Cantonese has a rich tradition in film, opera, and broadcast media that shapes brand voice, idiomatic expression, and consumer expectations — factors our transcreation specialists account for in marketing and PR projects.
