What are official translation services?
Official translation services are professional translations accompanied by a signed certification from a qualified translator or ISO 17100 translation company, confirming accuracy and completeness, and accepted as legally valid by UK Government departments, courts, universities, and foreign authorities for visa, legal, academic, and civil purposes.
What are the four types of official translation in the UK?
There are 4 types of official translation in the UK: certified translation, sworn translation, notarised translation, and apostille (legalised) translation, each carrying a different legal weight and accepted by different receiving authorities such as the Home Office, UKVI, HMCTS courts, and overseas consulates.
When do you need an official translation in the UK?
An official translation is required in the UK whenever a non-English document is submitted to a government body, court, regulator, university, or employer, including UKVI visa applications, Home Office settlement claims, HMCTS court proceedings, GMC medical registration, NARIC/ENIC qualification recognition, and Land Registry property transactions.
How much do official translation services cost in the UK?
Official translation services in the UK cost from £30 to £60 per page for standard civil documents such as birth or marriage certificates, and £0.12 to £0.18 per source word for business, legal, or technical content, with sworn, notarised, apostille, or same-day delivery applied as surcharges on top.
How does an official translation process work?
An official translation process works in 5 steps: send the document for a free quote, confirm the certification level required by the receiving authority, the translation is produced by an ISO 17100 native linguist, a second linguist proofreads it, and the certified PDF plus hard-copy original is delivered the same day where required.
Why are official translations rejected and how do you avoid it?
Official translations are rejected when the certification is missing the translator’s address, contact details, qualifications, or signature date; when only part of the document is translated; when stamps, seals, or handwritten notes are omitted; or when an apostille is affixed to the wrong document, all of which UKVI and the Home Office routinely refuse.

Complete guide
Everything you need to know
Across the United Kingdom, document translation is a regulated landscape where the receiving body — not the translator — decides which level of certification is valid, with the Home Office, UKVI, HMCTS, GMC, UK ENIC, Land Registry, and overseas consulates each setting distinct acceptance rules for certified, sworn, notarised, and apostille translations.
What are the four types of official translation in the UK?
There are 4 types of official translation in the UK: certified, sworn, notarised, and apostille (legalised) translation, each carrying a different legal weight and accepted by different receiving authorities including the Home Office, UKVI, HMCTS courts, and overseas consulates. Selecting the correct tier first — before ordering — is the single largest factor in avoiding rejection.
What is a certified translation?
A certified translation is an English translation accompanied by a signed Certificate of Accuracy from the translator or translation company, accepted by the Home Office, UKVI, DVLA, universities, and NHS bodies for civil documents such as birth certificates, marriage certificates, and academic transcripts. Certified translation is the standard tier for UK domestic use and covers approximately 85% of requests handled by UK agencies.
Documents delivered as certified translations include:
- Birth, marriage, and death certificates.
- Divorce decrees and adoption papers.
- Academic transcripts and diplomas for UK ENIC or university admissions.
- Driving licences for DVLA exchange.
- Police clearance and background check certificates for visa applications.
For dedicated processing of these documents, see our Certified Translation Services.
What is a sworn translation?
A sworn translation is a translation produced and signed by a translator who has sworn an oath before a competent authority, used mainly when the document is destined for a civil-law jurisdiction such as France, Spain, Italy, or Brazil where the UK certified format is not recognised. The UK has no domestic sworn translator register, so sworn translations are arranged through accredited counterparts in the destination country.
Sworn translation is required when:
- Submitting documents to French, Spanish, Italian, German, or Portuguese authorities.
- Registering a UK marriage or birth abroad in a civil-law state.
- Filing court evidence in a jurisdiction that recognises only sworn translators.
Order through our Sworn Translation Services page for jurisdiction-specific routing.
What is a notarised translation?
A notarised translation is a certified translation whose translator’s signature has been witnessed and verified by a notary public, required by some embassies, foreign universities, and overseas property or inheritance proceedings. The notary public confirms the identity of the translator and the authenticity of the signature — the notary does not assess translation quality, which remains the translator’s responsibility.
Notarised translation is required for:
- Embassy submissions for Chinese, UAE, Saudi Arabian, and Russian authorities.
- Overseas property purchases and inheritance probate.
- Power of attorney documents executed abroad.
- Foreign university admissions where the institution demands notary verification.
For end-to-end handling including notary appointment, see our Notarised Translation Services.
What is an apostille (legalised) translation?
An apostille translation is a notarised translation that has been legalised by the FCDO under the 1961 Hague Convention, used when the document must be recognised by a foreign government, with the apostille attached either to the original document, the translation, or both depending on destination country. The Hague Apostille Convention replaces full diplomatic legalisation with this single certificate among member states.
A recurring cause of rejection is affixing the apostille to the wrong document. The correct placement depends on destination:
- Apostille on the original — required where the destination authority needs the source document authenticated (most civil registry submissions).
- Apostille on the translator’s certification — required where the destination needs the translation legalised (court submissions, regulated professions abroad).
- Apostille on both — required by stricter jurisdictions such as Italy, Greece, and parts of Latin America.
The full apostille route, including FCDO submission, is managed through our Apostille Translation Services.
How do certified, sworn, notarised, and apostille translations compare?
Certified, sworn, notarised, and apostille translations differ in legal weight, who signs the certification, cost, and accepting authority, with certified translations starting at £30 per page and apostille translations adding £75–£150 plus FCDO fees on top.

How long does an official translation take?
An official translation takes 24 to 48 hours for standard one-to-three-page civil documents, with same-day turnaround available in London for documents submitted before 11 am and 3 to 5 working days for technical, legal, or longer documents.
| Document type | Standard turnaround | Express option |
|---|---|---|
| 1-page civil certificate | 24 hours | Same day (London, before 11 am) |
| 2 – 5 page civil bundle | 48 hours | 24 hours |

| Legal contracts and court evidence | 3 – 5 working days | 48 – 72 hours |

Why are official translations rejected and how do you avoid it?
Official translations are rejected when the certification is missing the translator’s address, contact details, qualifications, or signature date; when only part of the document is translated; when stamps, seals, or handwritten notes are omitted; or when an apostille is affixed to the wrong document, all of which UKVI and the Home Office routinely refuse.
What are the 7 most common reasons UKVI rejects a translation?
The 7 most common reasons UKVI rejects a translation are:
- No translator address on the certification.
- No dated signature, or a printed signature only.
- Missing or vague Statement of Accuracy wording.
- Partial translation — body text translated but stamps, seals, marginalia, or reverse-side notes omitted.
- Omitted official stamps, embossed seals, or registry numbers.
- Name mismatch against the passport (transliteration variants of Arabic, Russian, or Chinese names).
- Certification issued by an unqualified translator with no ITI, CIOL, or ISO 17100 backing.
How does ISO 17100 quality control prevent rejection?
ISO 17100 quality control prevents rejection by mandating native-speaker translators with documented qualifications, a separate second-linguist revision step, a defined certification template, and traceable project records, which together satisfy every Home Office and UKVI acceptance criterion. The standard’s revision requirement catches the partial-translation and omitted-stamp errors that account for the majority of rejections.
Which languages are covered by official translation services?
Official translation services in London and the UK cover 150+ languages, including Arabic, Mandarin Chinese, Spanish, French, German, Italian, Polish, Portuguese, Russian, Turkish, Urdu, Hindi, Greek, Korean, and Japanese, with native ISO 17100 linguists assigned to each language pair.

What accreditations should an official translation provider hold?
An official translation provider in the UK should hold ISO 17100 for translation services, ISO 27001 for information security, and membership of the Association of Translation Companies (ATC), with individual translators registered with the Institute of Translation and Interpreting (ITI) or the Chartered Institute of Linguists (CIOL).
What does ISO 17100 certification guarantee?
ISO 17100 certification guarantees that every translation is produced by a qualified native linguist, revised by a second independent linguist, delivered against a documented project workflow, and stored with full audit traceability. The standard specifies translator competence (qualification, experience, language proficiency), the mandatory revision step, and project-management records that are auditable on demand.
What do ITI, CIOL, and ATC membership mean?
ITI and CIOL are the two chartered UK bodies for individual qualified translators, and ATC is the UK trade association for accredited translation companies, with all three requiring proof of qualification, professional indemnity insurance, and adherence to a code of conduct.
- ITI — Institute of Translation and Interpreting, chartered membership with assessed entry routes.
- CIOL — Chartered Institute of Linguists, holding the Royal Charter and publishing certified-translation guidance.
- ATC — Association of Translation Companies, requiring ISO 17100 audit, indemnity cover, and code-of-conduct compliance from member firms.

Frequently asked questions
How much does it cost to get a document officially translated?
Official (certified) document translation in the UK costs between £60 and £150 per page, depending on the language pair and document complexity. Common documents such as birth certificates, marriage certificates, and diplomas tend to fall at the lower end of that range, while lengthy legal contracts or technical documents attract higher rates. Rare language pairs — for example, English to Tigrinya or Amharic — cost more than common European language pairs. Most agencies also charge a flat certification fee of around £10–£25 per document on top of the per-page rate.
Who can certify a translation in the UK?
In the UK, a translation can be certified by a professional translator or a translation agency that attaches a signed statement confirming the translation is accurate and complete. There is no single official body that must certify translations, but institutions such as the Home Office, UKVI, and UK courts accept translations certified by members of the Chartered Institute of Linguists (CIOL) or the Institute of Translation and Interpreting (ITI). Some applications — particularly for notarised documents — may additionally require a solicitor or notary public to authenticate the translator’s signature.
What is an officially certified translation?
An officially certified translation is a translated document accompanied by a signed declaration from a qualified translator or agency confirming that the translation is a true and accurate representation of the original. The certificate includes the translator’s name, qualifications, contact details, date, and signature, and is often stamped by the agency. Certified translations are required for official purposes such as UK visa and immigration applications, university admissions, court proceedings, and registering foreign documents with UK authorities. They are distinct from sworn translations used in some other countries, as the UK does not have a formal system of sworn translators.
How much does it cost to have a document translated?
Standard professional document translation in the UK is priced between £0.10 and £0.18 per source word, or £30 to £120 per page, depending on the language pair, subject matter, and turnaround time. A standard A4 page contains roughly 250–300 words, so a single-page document might cost £25–£55 for a common language pair such as French or Spanish into English. Technical, legal, or medical content commands higher rates due to specialist expertise required. Rush or same-day delivery services carry a surcharge of 25–50% on the standard rate.
How much should I pay someone to translate a document?
You should expect to pay a professional translator between £0.10 and £0.18 per word for standard documents in the UK, with rates rising for specialist fields such as legal, medical, or technical content. Freelance translators may charge slightly less than agencies, £0.08–£0.15 per word, but agencies provide quality assurance, certified declarations, and project management. Avoid very cheap offers (under £0.05 per word) as they often indicate machine translation with minimal human editing, which is not accepted for official UK submissions. For certified translations needed by UKVI or courts, using an established London translation agency ensures compliance with institutional requirements.
