Where to get a list of certified translators in UK

The UK has two main translation associations, ITI and CIOL, that certify translators and interpreters.

Chartered Institute of Linguists (CIOL)

How to find a chartered linguist: Go to the website, click “Find a Linguist” on the top menu, and use the filter below.

Pros:

• Certification Assurance: CIOL offers the Diploma in Translation, ensuring translators meet high standards.
• Ethical Standards: Members follow a strict code of conduct for ethical practices.

Cons:

• Limited Listings: Only lists members, excluding qualified non-members.
• No Official Seal: Lacks an official seal, which may be required for some formal documents.

Institute of Translation & Interpreting (ITI)

How to find a certified translator (MITI): Visit the website, click “Find a professional” on the top menu, and select a translator or interpreter.

Pros:

• Certification and Accreditation: ITI’s membership indicates translators have passed specific assessments.
• Certification Seals: ITI offers seals needed for officially recognized translations. As far as I know, ITI is the only association in UK providing official seals to certify documents.

Cons:

• Membership Restrictions: Only lists members who meet ITI’s strict qualifications.
• Rigorous Membership Process: The detailed qualification process can restrict immediate availability of translators.

The UK has no official government register — so what counts?

There is no single government list of “approved” translators in the UK. Instead, quality is signalled by membership of a recognised professional body: the Institute of Translation & Interpreting (ITI) and the Chartered Institute of Linguists (CIOL) for individuals, and the Association of Translation Companies (ATC) for agencies. A translation is accepted as “certified” when a qualified translator signs a statement confirming it is accurate — the translator’s credentials are what give that statement weight.

Where to look

• ITI directory (iti.org.uk) — search by language pair and specialism; members hold an MITI or FITI grade.
• CIOL “Find a Linguist” (ciol.org.uk) — the Chartered Institute of Linguists’ public register.
• ATC (atc.org.uk) — for vetted translation companies rather than individuals.

What to check before you hire

For Chinese-to-English certified work, confirm three things: the translator is a member of ITI or CIOL, they work in the exact direction you need (Chinese into English), and they will supply a signed certification statement with their contact details. You can see my own ITI-certified Chinese↔English profile and how I certify documents on the certified Chinese translation page above.
