Certified translation in the UK: the rules, in plain terms

There is no UK sworn translator

In Spain, a traductor jurado is appointed by the Ministerio de Asuntos Exteriores and their stamp carries legal authority. Nothing equivalent exists in the United Kingdom. There is no government register of authorised translators, no licence, no official seal. That surprises people, and it is the single biggest source of confusion for applicants arriving from Spain or Latin America.

Because the state does not certify translators, the UK regulates the document instead. A certified translation is a complete translation of the source document accompanied by a signed statement, from the translator or the translation company, confirming that the translation is true and accurate. The statement is the certification. Everything else — stamps, letterhead, membership logos — is supporting evidence of who stands behind it.

What UKVI requires

The Home Office is explicit about the four things a certified translation must carry when it accompanies a visa or settlement application:

• A confirmation from the translator that it is a true and accurate translation of the original document
• The date of the translation
• The translator's full name and signature (or the translation company's)
• The translator's or company's contact details

The translation must also be of the whole document. Partial translations, summaries and extracts are refused, including when the untranslated part is a stamp, a marginal note or a piece of boilerplate that looks unimportant. If part of the original is illegible, the translation must say so rather than quietly omit it.

Who is allowed to certify

Legally, anyone. Practically, that freedom is exactly why institutions scrutinise the certifier. A caseworker cannot verify a licence that does not exist, so they assess accountability instead: is there a named human being, do they belong to a professional body whose register can be checked, is there a company behind them, and can that company be contacted if the document is questioned.

The two professional bodies that matter in the UK are the Chartered Institute of Linguists (CIOL) and the Institute of Translation and Interpreting (ITI). Both maintain public registers, and membership grades — MCIL, MITI — are checkable by anyone. The Association of Translation Companies (ATC) plays a similar role for companies. None of these is a legal requirement; all of them reduce the risk of a query, which is the actual currency here.

Be sceptical of anything that looks like an official endorsement and is not. Roundels reading "100% approval", self-issued awards, and phrases like "government approved translator" describe things that do not exist. So does an anonymous certifying entity: a certificate that names no person is a certificate nobody is accountable for.

What a certificate should actually say

A well-formed statement of accuracy identifies the source document precisely enough that it cannot be swapped for another one — document type, issuing authority, issue date and reference number — and states the direction of translation explicitly. Ours reads:

I certify that the attached English translation of the [document type] issued by [issuing authority] on [issue date], reference [reference], is a true, complete and accurate translation of the original Spanish document, translated from Spanish into English. — [Reviewer name], [MCIL/MITI membership no.], for Accepted Translations · Date · [contact details] · Verify: acceptedtranslations.com/verify/[id]

The direction matters and is often templated backwards by high-volume providers. A certificate that claims to translate English into Spanish, attached to an English translation of a Spanish original, is internally inconsistent and gives a careful reader a reason to reject the whole thing.

Notarisation and apostilles

Notarisation is a notary public confirming the identity of the person who signed the statement. It says nothing about translation quality and UKVI does not require it. It is occasionally requested by foreign consulates, courts and some overseas universities.

An apostille, under the Hague Convention, authenticates the original public document for use abroad — typically obtained in the country that issued it, before translation. If you have been told you need an apostilled document, you need to deal with the issuing authority in Spain, not with a translator. We can arrange notarisation where a receiver requires it; tell us before ordering so the sequence is right.

Formats differ by receiver

The ATC, CIOL and ITI all give the same practical advice: check what the specific receiving body asks for. Universities often want the translation stapled or bound to a copy of the original. Some employers want a hard copy with a wet-ink signature. UKVI accepts scanned uploads. A translation that is perfect but formatted for the wrong receiver still causes a delay.

That is why our order form asks which institution the translation is for. It sets the format, and it is also what switches our guarantee on.
