Many Innovator Founder applicants are building a UK business from a career, an education and a financial history that sit in another language. Bank statements, degree certificates, marriage and birth certificates for dependants, and company documents from abroad can all end up in a visa application. If any of them are not in English or Welsh, they need a translation that meets specific standards.

This article sets out what a compliant translation must contain, the extra step for applicants inside the UK, and the mistakes that most often lead to delays or questions.

The translation requirement

A document that is not in English or Welsh must come with a translation that meets every element below.

RequirementApplies to
Independently verifiedAll applicants
Full translation (not extracts)All applicants
Confirms it is an accurate translationAll applicants
DatedAll applicants
Translator's or company's full nameAll applicants
Translator's or company's signatureAll applicants
Translator's or company's contact detailsAll applicants
Fully certified, with translator's credentialsApplicants applying in the UK

If any element is missing, the translation may not be accepted as it stands. The safest approach is to treat the table as a checklist for every translated document.

Applying from inside the UK: the extra step

Founders switching or extending in the UK face an additional requirement: the translation must be fully certified and include the translator's credentials. This matters for students switching after their course, founders extending on the same business, and anyone else applying in-country. A translation that would have been acceptable from outside the UK may not be enough for an in-country application if it lacks certification and credentials.

Documents that commonly need translating

The translation requirement applies to any document not in English or Welsh rather than to a fixed list, so the following are examples of documents that may arise in an Innovator Founder application and that applicants commonly hold in other languages:

  • Bank statements for the financial requirement, if you have been in the UK for 12 months or less and must show funds held for 28 days (£1,270 for the main applicant, plus £285 for a partner, £315 for the first child and £200 for each further child).
  • Relationship and birth documents for dependants. A partner must meet Appendix Relationship with Partner, and children's documents support their dependency.
  • Scholarship sponsor consent. If in the 12 months before applying you had a government or international scholarship agency award covering both fees and living costs for UK study, you need that sponsor's written consent.
  • Academic documents such as a results transcript where a student switching relies on it to show course completion.

Documents you gave your endorsing body during its assessment may also need compliant translations if you rely on them again in the visa application itself.

Common mistakes

Partial translations. Translating only the totals on a bank statement or the name and date on a certificate is not a full translation.

Self-translation or translation by a relative. The requirement for an independently verified translation makes this risky.

Missing elements. No date, no signature or no contact details. Each is a separate requirement.

Uncertified translations on in-country applications. The certification and credentials requirement applies when applying in the UK.

Mismatched details. Names and dates in the translation should match your passport and other documents exactly. Inconsistent spellings across documents can prompt questions.

Leaving it late. Professional translation and certification take time, and a translator may need to see originals or clearer copies before they will sign.

Translating an out-of-date document. A translation is only as useful as the document behind it. If a bank statement needs to cover a specific 28-day period, translate the statement that covers that period, not an older one you happened to have to hand.

A simple translation checklist

Before you submit, run through each translated document and confirm:

  1. The translation covers the whole document, including stamps and annotations.
  2. It states that it is an accurate translation.
  3. It is dated.
  4. It shows the translator's or company's full name, signature and contact details.
  5. If you are applying in the UK, it is fully certified and includes the translator's credentials.
  6. Names, dates of birth and reference numbers match your passport and other documents.

What happens if something is wrong

For some missing but fixable items, the caseworker guidance says caseworkers normally write out to let the applicant fix the problem; the example given is the Immigration Health Charge not being paid for the full period. Do not rely on that for translations. It is far better to submit compliant translations first time than to wait for a request, and any further information requests come with deadlines. See paragraph 39D information requests.

Build translation into your timeline

Translation should be scheduled alongside the other time-sensitive parts of your application. Your endorsement letter must be issued no more than three months before you apply, and funds evidence must cover a 28-day period. Order translations early so they are ready before your endorsement window starts to run. See the endorsement letter three-month validity and funds for dependants.

Key takeaways

  • Documents must be in English or Welsh, or have an independently verified full translation.
  • Each translation must confirm accuracy, be dated, and include the translator's or company's full name, signature and contact details.
  • In-country applications also need full certification and the translator's credentials.
  • Avoid partial translations, self-translation and mismatched names or dates.
  • Translations do not help with the separate B2 English requirement.
  • Order translations early so they do not squeeze the three-month endorsement window.
