When you apply for a passport, visa, mortgage or job, you may be asked to provide certified copies of important documents. Understanding Document Certification UK rules helps you avoid rejection and delays.
A certified document is a copy of an original document that has been confirmed as genuine by an authorised person. The certifier verifies that the copy matches the original document.

What Is Document Certification?
Document certification means confirming that a copy is a true and accurate version of the original document.
The certifier must:
- See the original document
- Compare it carefully with the copy
- Write a certification statement
- Sign and date the copy
The purpose is to prevent fraud and confirm authenticity.
Who Can Certify Documents in the UK?
In the UK, several professionals are legally recognised to certify documents.
Common authorised certifiers include:
- Solicitors
- Notaries public
- Chartered accountants
- Bank or building society officials
- Teachers (in some cases)
- Doctors
- Dentists
- Police officers
- Post Office document certification service
Some organisations also accept:
- Members of recognised professional bodies
- Company directors
- Religious ministers
However, the certifier usually must not be related to you or living at your address.
What Must Be Written on the Document?
The person certifying the document typically writes:
- “I certify that this is a true copy of the original.”
- Their signature
- Their printed name
- Professional title
- Date

Some institutions require specific wording, so always check their instructions first.

Certified copies are often required for:

Can a Friend or Family Member Certify Documents?

Using an unauthorised certifier may invalidate your documents.
