Certified translations accepted across the UK

What is a certified translation and when do UK authorities require one?

A certified translation is a foreign-language document rendered into English or Welsh and issued with a signed certificate of accuracy from a CIOL, ITI or ATC-registered translator, required whenever the Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC or a UK university asks for a foreign document in English.

Who can certify a translation in the UK?

In the UK, a translation may be certified by a professional translator or translation company registered with the Chartered Institute of Linguists (CIOL), the Institute of Translation and Interpreting (ITI) or the Association of Translation Companies (ATC), because gov.uk guidance on certifying a document requires the certifier to state their name, address, signature and date in writing.

How much does a certified translation cost in the UK?

A certified translation in the UK costs from £25 per document at Certified Translation Services UK for a short personal certificate, with longer documents priced £0.10–£0.20 per source word depending on language pair and subject; same-day or weekend delivery adds a 30–50% surcharge on the standard price.

What are the different types of certification — certified, notarised, sworn and apostille?

The UK recognises four practical certification tiers: standard certified (signed accuracy statement), notarised (certified plus a notary public witnessing the translator's signature), sworn (a translator registered with a foreign court, used for continental European submissions) and apostilled (an FCDO stamp authenticating a notarised translation for Hague Convention countries).

Will a certified translation be accepted by the Home Office, UKVI and other UK authorities?

Yes — a certified translation from Certified Translation Services UK is accepted by the Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC and UK universities, because every job is produced by a CIOL, ITI or ATC-registered translator under an ISO 17100 workflow and delivered with a signed certificate of accuracy meeting the gov.uk certifying-a-document criteria.

What types of documents require certified translation in the UK?

Documents that require certified translation in the UK include birth, marriage and death certificates, divorce decrees, passports and national ID cards, academic diplomas and transcripts, court documents, employment references, bank statements, medical records, tenancy agreements, driving licences and company registration documents — anything a UK authority needs to read in English.

A certified translation is a foreign-language document rendered into English or Welsh and issued with a signed certificate of accuracy from a CIOL, ITI or ATC-registered translator. Certified Translation Services UK produces these translations from £25 per document, in 2–3 working days, across 150+ languages, accepted by the Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC, UK universities and government bodies across the UK and internationally. For the underlying tier taxonomy and ISO 17100 workflow, see our Certified Translation hub.

What is a certified translation and when do UK authorities require one?

A certified translation is a foreign-language document converted into English or Welsh and issued with a signed certificate of accuracy from a CIOL, ITI or ATC-registered translator. UK authorities require one whenever an official body must read a foreign document in English — the Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC or a UK university. Every certified translation carries a statement of truth, the translator's name, address, signature and date.

Certified translations differ from a casual bilingual rendering in three respects:

Which UK authorities accept a certified translation?

Certified translations accepted by UK authorities include those submitted to the Home Office, UKVI, HM Passport Office, HM Courts and Tribunals Service, UK ENIC, the GMC, the NHS, UK universities and most local councils. Acceptance is conditional on the certificate carrying the translator's name, address, signature and date, per gov.uk guidance on certifying a document.

UK receiving body	Typical use	Tier required
Home Office / UKVI	Visa, settlement, naturalisation	Standard certified translation
HM Passport Office	Passport supporting documents	Standard certified translation
HM Courts and Tribunals Service	Court documents and evidence	Certified; wet-ink hardcopy
UK ENIC	Credential evaluation	Standard certified translation
UK universities	Admission, transcripts, diplomas	Standard certified translation
GMC / NMC / NHS	Professional registration	Standard certified translation

What official use cases trigger the need for a certified translation?

Certified translations are triggered by seven common official use cases:

1. Visa applications and spouse/settlement casework.
2. Naturalisation and citizenship applications.
3. UK passport applications with foreign supporting documents.
4. Court proceedings and witness statements.
5. University admission and academic transcripts.
6. Credential evaluation with UK ENIC.
7. Civil registration of foreign births, marriages and deaths.

Who can certify a translation in the UK?

In the UK, a translation may be certified by a professional translator or translation company registered with the Chartered Institute of Linguists (CIOL), the Institute of Translation and Interpreting (ITI) or the Association of Translation Companies (ATC). The gov.uk guidance on certifying a document requires the certifier to state their name, address, signature and date in writing. For the step-by-step workflow, see How To Certify A Translation.

What does CIOL, ITI or ATC membership add to a certified translation?

CIOL and ITI membership confirms the individual linguist holds recognised qualifications and follows a professional code of conduct. ATC registration confirms the translation company operates to industry standards with a formal complaints procedure. Together, these credentials satisfy UK receiving bodies that the translator identified on the certificate is qualified.

Can I certify my own translation in the UK?

No — you cannot certify your own translation in the UK, even if you are bilingual. The gov.uk guidance on certifying a document requires the certifier to be independent of the applicant. UKVI and the Home Office routinely reject self-certified translations submitted with visa or passport applications, because the certificate must come from an independent professional translator.

What must a compliant UK certificate of accuracy contain?

A compliant UK certificate of accuracy contains six mandatory elements, matching gov.uk 'certifying a document' criteria used by the Home Office and UKVI:

1. A statement of truth confirming the translation is true and accurate.
2. The translator's full name.
3. The translator's business address.
4. The translator's signature.
5. The date of certification.
6. The source and target languages.

How much does a certified translation cost in the UK?

A certified translation in the UK costs from £25 per document at Certified Translation Services UK for a short personal certificate. Longer documents are priced at £0.10–£0.20 per source word, depending on language pair and subject. Same-day and weekend delivery adds a 30–50% surcharge on the standard price.

Long-form multi-page documents	250+ words	£0.10–£0.20 per source word
Same-day or weekend delivery	Any length	+30–50% surcharge

Which four factors change the price of a certified translation?

Four factors change the price of certified document translation in the UK:

1. Language-pair rarity — common European pairs sit at the lower band.
2. Subject-matter complexity — legal, medical and technical texts sit higher.
3. Document length beyond a standard 250-word single page.
4. Turnaround urgency — triggers the 30–50% same-day surcharge.

What is included in the price?

Every certified translation includes five deliverables at no extra cost:

What are the different types of certification — certified, notarised, sworn and apostille?

The UK recognises four practical certification tiers: standard certified, notarised, sworn and apostilled. Each maps to a distinct receiving body and use case. For the notarised tier in detail, see Notarised.

Certified vs notarised vs sworn vs apostille: which UK body accepts which?

The comparison table below maps each tier to the receiving body that accepts it:

Tier	What it adds	Accepted by (UK / abroad)
Standard certified translation	Signed certificate of accuracy	Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC, UK universities, GMC, NHS
Notarised translation	Notary public witnesses translator's signature	Foreign consulates, overseas courts, some foreign universities
Sworn translation	Translator registered with a foreign court	Continental European legal systems (France, Spain, Italy, Germany)
Apostilled translation	FCDO stamp legalising the notary's signature	125+ Hague Apostille Convention countries

When do you need a notarised translation instead of a certified one?

You need a notarised translation instead of a standard certified translation when the document is being sent outside the UK to a foreign court, embassy, university or consulate that requires a UK notary public to witness the translator's signature. Most UK-facing applications require only a certified translation.

When do you need an apostille and FCDO legalisation on top?

You need an apostille and FCDO legalisation on top of a notarised translation when the destination country is party to the Hague Apostille Convention and requires proof that the UK notary's signature is genuine. Translation and legalisation together are required by many overseas registrars, courts and universities. UK legalisation is handled through the Foreign, Commonwealth and Development Office (FCDO).

Do sworn translators exist in the UK?

No — sworn translators do not exist as a statutory category in the UK. The UK legal system has no register of court-sworn translators. The equivalent recognition is CIOL, ITI or ATC membership. A UK 'sworn translation' is produced by a translator registered with a foreign court for documents destined abroad.

Will a certified translation be accepted by the Home Office, UKVI and other UK authorities?

Yes — a certified translation from Certified Translation Services UK is accepted by the Home Office, UKVI, HM Passport Office, HM Courts, UK ENIC and UK universities. Every job is produced by a CIOL, ITI or ATC-registered translator under an ISO 17100 workflow and delivered with a signed certificate of accuracy that meets the gov.uk certifying-a-document criteria.

What are the UKVI requirements for a certified translation?

The UKVI requirements for certified translations accepted for official UK visa and immigration casework are:

Why do certified translations get rejected — and how to avoid it?

Certified translations are typically rejected for four concrete reasons, each preventable through a specific ISO 17100 checkpoint:

UKVI rejection reason	ISO 17100 checkpoint that prevents it
Missing translator business address	Certificate template audit before sign-off
Wrong 'true and accurate' wording	Statement-of-truth clause locked in workflow
Undated certificate	Date-stamp check by second linguist
Scanned signature where wet-ink required	Delivery-format confirmation at project setup

Do I need a hard copy or is a PDF enough?

A signed PDF is enough for most UKVI, Home Office and university applications submitted online. HM Courts, some registrars and foreign consulates require a wet-ink hardcopy. Certified Translation Services UK posts a hardcopy on request at no extra charge from the London office.

What types of documents require certified translation in the UK?

Documents requiring certified translation in the UK include personal certificates, academic records, legal papers and corporate documents — anything a UK authority needs to read in English. Certified translations for official use cover birth, marriage and death certificates, degrees, court documents, contracts and company filings.

Which personal documents are most commonly certified?

The most commonly certified personal documents are:

Which academic and professional documents need certification?

Academic and professional documents needing certification include degree certificates, diplomas, academic transcripts, professional licences and employment references. Common triggers are UK ENIC credential evaluation, university admission, skilled worker visas and GMC or NMC registration. For sector detail see Academic Translation Services for UK Universities, Research and Credential Evaluation.

Which legal and corporate documents need certified translation?

Legal and corporate documents needing certified translation include court documents, contracts, powers of attorney, company registration papers, tenancy agreements, property deeds and insurance policies. Documents official and legal in nature are often delivered with a notarised or apostilled uplift when destined for overseas courts or registries.

How long does it take to get a certified translation in the UK?

Standard turnaround time at Certified Translation Services UK is 2–3 working days for every document type, single-page or multi-page. Documents under 1,000 words can be delivered within 24 hours. Same-day and weekend delivery is available at a 30–50% surcharge. Large technical, legal or regulatory projects are quoted individually.

How does same-day and weekend delivery work?

Same-day and weekend delivery works by prioritising the job through the ISO 17100 workflow at a 30–50% surcharge on the standard price. Availability depends on translator capacity in the language pair. The London office is open Monday to Saturday, 9:00–18:00.

How long is a certified translation valid?

A certified translation has no statutory expiry in the UK and remains valid as long as the source document itself is valid. UKVI and the Home Office occasionally request a re-issue for translations older than three years when the underlying original document has been updated.

How do I order a certified translation online in the UK?

You order a certified translation online by sending a clear scan, receiving a fixed-fee quote and receiving the signed PDF in 2–3 working days. The four-step ordering workflow is:

1. Email a clear colour scan or photograph of the original document.
2. Receive a fixed-fee quote and delivery date within office hours.
3. Confirm the language pair, turnaround and delivery format.
4. Receive the signed PDF by email; wet-ink hardcopy posted on request.

Can I use a scan or do I need to send the original document?

A clear colour scan or high-resolution photograph is sufficient for most certified translations. UK receiving bodies check the translated document against the applicant's original at submission. Originals are only required when a UK notary public must sight the document for a notarised or apostilled tier.

How do I get a free quote?

You get a free quote by emailing a scan or calling the London office on +44 20 7459 4983 during opening hours, Monday to Saturday, 9:00–18:00. Quotes for personal certificates are typically returned within one working hour.

Which certified translation services are the best in the UK?

The best certified translation services in the UK combine three verifiable signals: individual translators registered with CIOL or ITI, the translation company registered with the ATC, and an ISO 17100 workflow with second-linguist review. Certified Translation Services UK holds all three and displays them on every certificate of accuracy — which is included in every order at no extra cost.

What credentials should a UK certified translation company hold?

A UK certified translation company should hold:

• ATC membership at company level — the Association of Translation Companies sets binding codes of practice that govern how certifications are issued and quality-controlled.
• Individual CIOL or ITI membership for translators — every translator must be qualified in their subject area and registered with a recognised professional body, so the signed certificate of accuracy carries full legal weight with the Home Office, UKVI, courts, and government bodies.
• An ISO 17100 process mandating a second linguist reviews every job — this two-stage workflow catches errors before delivery and is the benchmark quality standard for professional translation in the UK.
• Transparent pricing and turnaround commitments — reputable providers state their rates and delivery windows clearly, with no hidden fees for certification.

Frequently asked questions

How much does a certified translation cost in the UK?

Certified translation in the UK starts from £25 per document for single personal certificates such as birth, marriage, or death certificates, diplomas, passports, and ID cards. For longer or more complex documents, pricing runs from £0.10 to £0.20 per word depending on the language pair and subject matter. Large technical, legal, or regulatory projects are quoted individually. A signed certificate of accuracy is included at no extra cost in every translation.

Who can certify a translation in the UK?

In the UK, any qualified, competent translator can produce a certified translation by attaching a signed certificate of accuracy to their work — there is no single government-appointed body that must approve them. The Home Office, HM Passport Office, and UK courts typically accept translations from professional translation companies that follow a rigorous quality process, such as ISO 17100, where every translation is checked by a second linguist. Always confirm the accepting authority's specific requirements before commissioning a translation.

Who can certify translation in the UK?

Any professional translator or translation agency that signs a certificate of accuracy can certify a translation in the UK. Unlike some countries with a formal sworn-translator system, the UK has no state-appointed requirement — however, accepting bodies such as the Home Office and UKVI expect translations to be completed by a qualified professional and accompanied by a signed statement confirming accuracy. Agencies following ISO 17100 standards, with subject-qualified translators and a second-linguist review, are widely accepted.

Can I certify my own translation?

You cannot certify your own translation for official UK purposes if you are the subject of the document. The Home Office, HM Passport Office, and UKVI require that the certifier be an independent, qualified professional who was not involved in creating the original document. A friend or family member is equally ineligible. The translation must be accompanied by a signed certificate of accuracy from an independent translator or agency confirming it is a true and accurate representation of the original.

Can I do my own certified translation?

No — you cannot certify a translation of a document that relates to you or your application. UK authorities including the Home Office and UKVI require the translation and its certificate of accuracy to come from an independent, qualified professional. Submitting a self-certified translation is likely to result in your application being rejected. A professional certified translation, starting from £25 per document, is the accepted route for immigration, legal, and official purposes.

What is the difference between an official translation and a certified translation?

A certified translation is a translated document accompanied by a signed certificate of accuracy from a qualified translator or agency, confirming it is a true and complete rendering of the original. The term 'official translation' is informal and can mean different things in different contexts — it is not a recognised legal standard in the UK. For UK Home Office, court, university, or employer submissions, 'certified translation' is the correct and accepted term. Always check that your translation includes a signed certificate of accuracy.

How do I know if a translation is certified?

A certified translation will include a signed certificate of accuracy — a written statement from the translator or agency declaring that the translation is complete and accurate to the best of their professional knowledge. It should state the translator's name, qualifications or company details, the date, and a description of the original document. Reputable agencies following ISO 17100 processes include this certificate as standard with every translation, at no extra cost.

Do sworn translators exist in the UK?

The UK does not have an official 'sworn translator' system in the way that many European countries do. In countries such as Germany, France, and Spain, translators can be formally sworn in by a court and hold a state-recognised title. In the UK, certified translation is produced by qualified professionals who sign a certificate of accuracy, and this is accepted by the Home Office, UKVI, courts, and other authorities. No additional notarisation or oath is required for the vast majority of UK official submissions.

How can I get certified translation of official documents in the UK?

You can get certified translation of official documents in the UK by contacting a professional translation agency that follows ISO 17100 standards and provides a signed certificate of accuracy with every translation. For single personal documents — birth certificates, marriage certificates, diplomas, passports, and IDs — prices start from £25 per document, with a standard turnaround of 2–3 working days. Same-day and weekend delivery are available at a 30–50% surcharge. You can request a quote by calling +44 20 7459 4983 or visiting 71-75 Shelton Street, London WC2H 9JQ.

Where can I find UKVI certified translation services?

UKVI-accepted certified translation services are offered by professional UK translation agencies that provide a signed certificate of accuracy and follow a recognised quality process such as ISO 17100. When submitting documents to UK Visas and Immigration, the translation must be completed by a qualified professional — not the applicant or a family member. Personal documents such as birth certificates and passports start from £25 per document, with standard delivery in 2–3 working days. Same-day service is available at a 30–50% surcharge.

How do I find a certified translator?

Look for a professional translation agency or individual translator that works to ISO 17100 standards, employs subject-qualified translators, and includes a signed certificate of accuracy with every translation. Confirm that the agency is accepted by the authority you are submitting to — such as the Home Office, UKVI, or a UK court. A reputable UK service will cover 150+ languages, quote clearly (personal documents from £25), and deliver within 2–3 working days, with same-day options at a 30–50% surcharge.

Can anyone do a certified translation?

No — a certified translation must be produced by a qualified, independent professional, not by the applicant, a family member, or an unqualified bilingual individual. In the UK, the translator or agency must attach a signed certificate of accuracy confirming the translation is complete and correct. Agencies following ISO 17100 standards — using subject-qualified translators and a second-linguist review — provide the level of quality that the Home Office, UKVI, courts, and universities expect. Self-prepared or uncertified translations are routinely rejected by these bodies.

How much does it cost to officially translate a document?

Officially translating a single personal document in the UK — such as a birth certificate, marriage certificate, diploma, or passport — costs from £25 per document. For longer or more complex documents, pricing is typically £0.10–£0.20 per word depending on the language pair and subject. Large legal, technical, or regulatory projects are quoted individually. Every certified translation includes a signed certificate of accuracy at no extra cost, and standard turnaround is 2–3 working days.

How much do document translation services cost?

Document translation costs in the UK vary by document type, length, and language pair. For certified personal documents — birth certificates, marriage certificates, diplomas, passports, and IDs — prices start from £25 per document. Longer documents are priced at £0.10–£0.20 per word. Large technical, legal, or regulatory projects are quoted individually based on scope. Same-day or weekend delivery is available at a 30–50% surcharge. All certified translations include a signed certificate of accuracy at no extra cost.

Where can I get notarised translation services in the UK?

Notarised translation in the UK involves a certified translation that is then signed and stamped by a notary public, which is required for certain international legal and corporate documents. The process typically starts with a certified translation — from £25 for personal documents, with a 2–3 working day turnaround — which is then presented to a notary. Not every UK submission requires notarisation; the Home Office and UKVI generally accept certified translations without a notary. Contact +44 20 7459 4983 to confirm the exact requirements for your document.

Is ChatGPT a good translator?

ChatGPT is not suitable for certified translation of official documents. UK authorities including the Home Office, UKVI, and courts require translations to be produced by a qualified human professional who can sign a certificate of accuracy — an AI tool cannot do this. Machine-generated translations also carry risks of errors in legal or technical terminology that can have serious consequences for immigration or legal applications. For accepted certified translations, a professional agency following ISO 17100 standards is required.
