Certified Translations


When members of public, businesses and public authorities need a certified translation of a document that is not in English, it is important to choose a qualified, registered translator or translation company.

This expectation is clearly set out by the UK Government at or by clicking the logo below.

Use a qualified, registered translator or translation company

All parties, and especially public authorities can reduce the risk of error or omission by only using a translator or translation company with a clear affiliation to a recognised professional body or association such as the Chartered Institute of Linguists, the Institute of Translation and Interpreting (ITI) and the Association of Translation Companies (ATC).




Find the right professional for your translation

CIOL, ITI and ATC maintain easily accessed public registers of accredited translators and companies:


Get a Certificate

As per government guidance the translation document is best annotated or accompanied by a certificate with at least the following information:

  • The translation is ‘a true and accurate translation of the original document’
  • The date of the translation
  • The name and contact details of the translator or a representative of the translation company


Take Confidence in Quality 

Businesses, public service and UK Government agencies can take confidence in the accreditation processes for experienced professional translator members of the Chartered Institute of Linguists (MCIL and FCIL) and the Institute of Translation and Interpreting (MITI, FITI and Corporate LSP members) and also in the quality assurance processes of ATC member companies (Accredited).

All three organisations endorse each other’s guidance for certifying a translation as here on the ATC and ITI websites.
