Clear explanation
What Is a Certified Translation?
A certified translation is a translated document accompanied by a signed and dated statement confirming that the translation is a true and accurate rendering of the original.
It is commonly requested when information written in one language must be submitted to an organisation that requires both the translated content and formal confirmation of its accuracy.
Requirements can differ between authorities, courts, universities, employers, professional bodies and other recipients. Check the receiving organisation's instructions before ordering, particularly if they mention notarisation, legalisation or an apostille.
In simple terms
If the organisation receiving your document asks for a certified translation, you normally need the translation together with its signed certification statement rather than a standard translation alone.
When certification is commonly required
Certified Translation for Important Applications and Records
The right format depends on the purpose of the document and the organisation receiving it. These are some of the most common situations.
Academic Applications
Diplomas, degrees, transcripts, qualifications and educational records required by schools, universities and other institutions.
Legal & Court Matters
Statements, agreements, orders, judgments and supporting documents required for legal review, proceedings or declarations.
Employment & Licensing
Professional qualifications, employment records, licences, references and supporting documents used for registration or work.
Financial & Administrative Use
Bank statements, payslips, tax records and other documentation required for financial, application or administrative purposes.
Business Documentation
Company records, compliance material, contracts and supporting documents used in international or cross-border activity.
Choose the right format
Certified, Notarised or Legalised?
These terms describe different levels of document support. They are not interchangeable, so the receiving organisation should confirm exactly what it requires. If an overseas authority specifically asks for a sworn translation, use that route rather than assuming UK-style certification is sufficient.
| Service | What it means | When it may be required |
|---|---|---|
| Certified translation | The translated document is accompanied by a signed and dated statement confirming that the translation is true and accurate. | Common for official, academic, legal, immigration and administrative document submissions. |
| Notarisation | An additional formal verification step is added when specifically requested. | Some recipients or overseas processes request notarisation in addition to the translation. |
| Apostille / legalisation | An authentication process that may apply to certain documents being used internationally. | Certain overseas authorities or procedures may require authentication as well as translation. |
Not sure which option applies? Send the document together with any instructions from the receiving organisation before placing your order.

Check the Receiving Organisation's Requirements
Certified translations are commonly prepared for documents being submitted during immigration, passport, academic, legal, employment and other formal processes in the UK.
Where your documents are intended for the Home Office or UKVI, HM Passport Office, a court, university, employer, solicitor or professional body, check the recipient's current instructions first. If written requirements have been supplied, send them with your files.
This is particularly important if the organisation asks for notarisation, an apostille, legalisation, a printed copy or another specific form of certification.
