What Is a Certified Translation? Everything You Need to Know
A certified translation is more than an accurate translation. It comes with a formal declaration from the translator. Here's exactly what that means.
Have you been asked for a "certified translation" for a visa application, court case, or other official purpose? You may wonder what makes a translation "certified." The term means different things in different countries. That adds to the confusion.
This guide explains what a certified translation is and what it must include. It also covers who can produce one, and how it compares to sworn, notarised, and apostilled translations.
The Definition
What Is a Certified Translation?
A certified translation is a translation that comes with a signed statement (a declaration or certificate) from the translator or translation company. The statement confirms that the translation is a complete and accurate version of the original document. The translator takes personal responsibility for the accuracy of the translation.
The key difference is accountability. A regular translation has no formal guarantee. Anyone could have done it, and there is no way to check who translated it or if they were qualified. A certified translation creates a chain you can verify. A named translator, with contact details, puts their professional reputation behind the accuracy of the translation.
Components of a Certified Translation
For UKVI and most other immigration authorities, a "certified" translation must include these elements:
Required Elements
- The translation itself — A complete, accurate translation of the whole document. It should keep the original format and layout where possible
- Translator's declaration — A formal statement that the translation is accurate and complete
- Translator's full name — The name of the person who did the translation
- Translator's signature — Physical or digital signature
- Translator's contact details — Address, phone, or email so the translation can be checked
- Translator's qualifications — Professional credentials or experience
- Date of translation — When the translation was completed
- Copy of the original document — Usually attached to or bound with the translation
Example Certification Statement
"I, [Translator Name], hereby certify that the attached translation from [Source Language] into English is a true and accurate translation of the original document. I am competent to translate from [Source Language] into English and have the relevant qualifications and experience to do so."
Translator: [Full Name]
Qualifications: [e.g., MA Translation Studies, CIOL Member]
Contact: [Address, Email, Phone]
Signature: _______________
Date: [DD/MM/YYYY]
Certified vs Sworn vs Notarised vs Apostilled
These four terms are often confused. Here's how they differ:
| Type | What It Is | Who Provides It | Required for UKVI? |
|---|---|---|---|
| Certified | Translation + translator's declaration of accuracy | Qualified translator or agency | Yes — standard requirement |
| Sworn | Translation by a court-registered translator who has taken a legal oath | Sworn translator (EU countries) | Accepted but not required |
| Notarised | Translation witnessed by a notary public or solicitor | Notary public + translator | Not required by UKVI |
| Apostilled | Document authenticated for international use under the Hague Convention | Government authority (FCO in UK) | Not required by UKVI |

Who Can Produce a Certified Translation?
Some countries, such as France or Germany, keep a government list of approved translators. The UK does not. There is no single accrediting body. However, UKVI expects translators to be:
Widely Accepted
- • Professional translation companies
- • Members of ITI or CIOL
- • University-qualified translators
- • NAATI-certified translators (Australia)
- • ATA-certified translators (USA)
Potentially Questioned
- • Bilingual individuals without credentials
- • Non-professional translators
- • Family members or friends
- • The applicant themselves
- • Machine/AI translation tools
How to Verify a Certified Translation Is Legitimate
Have you received a certified translation and want to check it is genuine? Look for these signs:
The declaration names a specific translator with contact details you can check
The translation company has a registered business address and website
You can check the translator's qualifications with professional bodies
The translation covers every part of the original document
The layout matches the original document's structure
A digital signature or stamp is present (common but not strictly required)
Frequently Asked Questions
Is a certified translation the same everywhere?
No. "Certified translation" means different things in different countries. In the UK, it means a translation with a translator's declaration. In the US, it requires a specific certification statement. In Canada, a sworn affidavit may be needed. In many EU countries, only court-registered "sworn translators" can certify translations. Always check the rules of the authority you're applying to.
Does a certified translation need a stamp?
UKVI does not strictly require a stamp. What matters is the translator's declaration with signature, name, and contact details. Many professional translation companies still add a company stamp as an extra mark of authenticity. Some other countries' immigration authorities do expect one.
Can a certified translation be digital?
Yes. UKVI accepts digital certified translations sent as PDF documents. The translator's declaration can include a digital signature. This is the standard for online translation services. It is fully accepted for visa applications made through the online portal.
How long does a certified translation take?
Standard turnaround is 24-48 hours for most documents. Simple documents like birth certificates can often be done the same day. Complex or long documents may take 3-5 business days. See our rush translation guide for urgent options.
How much does a certified translation cost?
Certified translation typically costs £15-30 per page. The price depends on the language pair, how complex the document is, and how fast you need it. See our complete pricing guide for detailed cost breakdowns.

Frequently Asked Questions
What is a certified translation?
A certified translation comes with a signed statement from the translator. The statement confirms the translation is a true and accurate version of the original. It includes the translator’s name, qualifications, contact details, and the date of translation. UKVI, HMCTS, USCIS, and most UK regulators accept certified translations without extra notarisation.
Who can certify a translation in the UK?
Any professional translator can certify a translation in the UK — there is no government licensing system. In practice, a certification is credible when it comes from a translator with contact details and qualifications you can check (CIOL, ITI, or ATC membership, or a university translation degree). UKVI does not keep an approved list of translators. The certification format is what matters.
Does the UK have a register of approved certified translators?
No. Spain, France, Germany, and Italy keep sworn-translator registers. The UK has no government list. UKVI guidance simply requires the translation to be "certified by a professional translator." A translation from any qualified translator you can verify is acceptable.
Is a certified translation the same as a notarised translation?
No. A certified translation is signed by the translator under their professional credentials. A notarised translation is a certified translation that is also signed before a notary public. The notary confirms the translator’s identity — not the accuracy of the translation. UKVI does not require notarisation for standard visa applications.
How long is a certified translation valid?
A certified translation has no expiry date. It stays valid for as long as the original document is valid. Some authorities, such as UK universities and certain mortgage lenders, prefer translations issued in the last 6–12 months. For visa applications, a translation made any time after the original document was issued is acceptable.
Does UKVI accept digital certified translations?
Yes. UKVI accepts digital certified translations (PDF) with the translator’s digital signature applied. We supply every translation with a PAdES-LTV compliant digital signature. It works for both online visa submissions and paper applications.
