At some point in the UK, you will be asked for a “certified copy” of a document.
For many people — especially immigrants — this phrase causes confusion. Is a scan enough? Do you need a solicitor? Is this the same as notarisation?
This post explains, plainly, what a certified copy means in the UK, who can certify documents, and when you actually need one.
What a certified copy is
A certified copy is a copy of an original document that has been confirmed as genuine by an authorised person.
The certifier:
- sees the original document
- compares it to the copy
- confirms that the copy is a true and accurate reproduction
They then sign, date, and usually stamp the copy.
The copy is used instead of the original, so you don’t have to send important documents by post. If you don’t yet have a simple way to store copies securely, this guide to a digital filing system can help.
What certification is not
A certified copy is not:
- a scan or photo you took yourself
- a screenshot
- a document downloaded from email and renamed
- the same as notarisation (more on that below)
If no person has verified the copy against the original, it is not certified.
Who can certify documents in the UK
Who is allowed to certify a document depends on the organisation asking for it.
Commonly accepted certifiers include:
- solicitors
- notaries public
- chartered accountants
- some regulated professionals (for example, certain teachers or doctors)
For immigration, legal, or international use, requirements are usually stricter.
Always check what the requesting organisation accepts.
What a certified copy usually looks like
A certified copy normally includes:
- a statement such as “I certify this is a true copy of the original”
- the certifier’s signature
- their name and profession
- a date
- sometimes a stamp
If a copy has none of these, it is unlikely to be accepted as certified.
When you usually need a certified copy
Certified copies are commonly requested for:
- visa and immigration applications
- citizenship or settlement applications
- legal processes
- some financial or inheritance matters
- submitting documents to authorities outside the UK
In these cases, sending originals is risky or impractical, so certified copies are used instead.
When you usually do not need a certified copy
You usually do not need certified copies for:
- proof of address
- bank statements
- utility bills
- payslips
- employment contracts
- GP registration
- most day-to-day admin
In these situations, digital copies or PDFs are normally enough unless explicitly stated otherwise. If you're unsure when a digital document is accepted in the UK, see Digital vs Physical Documents: What the UK Actually Accepts.
Certified copy vs notarised document
These are often confused.
A certified copy:
- confirms the copy matches the original
- is usually done by a solicitor or authorised professional
- is often enough for UK-based processes
A notarised document:
- is handled by a notary public
- is usually required for documents used abroad
- involves a higher level of formal verification
If an organisation asks for notarisation, a certified copy is usually not sufficient.
How to know what you actually need
If a request is unclear:
- check the exact wording (certified, notarised, original)
- look for guidance on the organisation’s website
- ask them directly if a certified copy is acceptable
Do not assume. Requirements vary, and guessing often leads to rejection.
A practical approach
For most people, a simple rule works:
- keep originals of important documents safe (ideally as part of your first adult documents pack)
- use digital copies for everyday admin
- get certified copies only when explicitly required
You do not need to certify documents “just in case”.
Final note
The UK relies heavily on trust and verification, but not everything needs the highest level of formality.
Understanding what a certified copy actually is — and when it is required — prevents unnecessary cost, stress, and delays.
That clarity is often more important than the document itself.
