What Makes a Translation ‘Certified’ in the UK?
19th Jun 2025
When a UK authority asks for a “certified translation,” what does that really mean? It's not just about word‑for‑word accuracy. A certified translation in the UK carries a formal declaration of authenticity, often from a translator with recognised credentials or professional membership, ensuring it meets strict standards set by bodies such as UKVI, HM Passport Office, or UK universities. Understanding “Certified Translation” in the UK
“Certified translation” is the official term used when a translator provides a signed statement (often called a Certificate of Accuracy) confirming that the translation is a true and accurate record of the original. This certification differentiates it from standard translations and is frequently required by legal, academic, immigration, and governmental institutions.- Definition of certified translation — In the UK, a certified translation must include:
- A translator’s signature
- Their professional credentials (e.g., ATC membership or equivalent)
- A statement affirming accuracy and completeness
- When certification is legally required — For critical documents like birth certificates, academic diplomas, police certificates, or medical records, institutions such as UK Visas & Immigration (UKVI), courts, universities, and HM Passport Office all frequently request certified versions.
- Certified vs sworn vs notarised vs apostilled — These terms often cause confusion. A certified translation is based on the translator’s declaration. “Sworn” (more common in civil-law countries) involves a translator taking an oath. “Notarised” adds a notary public's seal, and “apostilled” involves a government stamp under The Hague Convention. The right option depends on your destination and purpose.
Who Can Issue Certified Translations in the UK?
A vital question: who qualifies to provide certified translations?- Certified translators and ATC members — In the UK, the Association of Translation Companies (ATC) promotes best practices and publishes guidance . Working with an ATC‑registered translator ensures your document meets recognised standards.
- Translator’s declaration of accuracy — The statement typically reads: “I [translator’s name], hereby certify that this translation is, to the best of my knowledge and belief, an accurate and complete translation of the original document.” It includes the translator’s signature, date, full name, and contact information.
- Example of a Certificate of Accuracy — This usually appears on office letterhead, including contact details and, where possible, professional body affiliations (like the ATC or Chartered Institute of Linguists).
Which UK Authorities Require Certified Translations?
Different UK authorities have unique standards and expectations.- UK Visas & Immigration (UKVI) — UKVI often requires certified translations for essential documents. These must include complete foreign-language versions and a literal English translation with certification.

Mistakes to Avoid with Certified Translations
