Certified bank statements explained
Updated August 2026 · 5 minute read
A certified bank statement is a copy that somebody with standing has attested is a true copy of the original. Only a third party can do that, and the phrase covers four different documents, so ask which one you need.
Why anyone asks for one
A PDF downloaded from online banking is trivially editable. Anyone assessing a statement knows this, and for most purposes they accept the risk because the consequences of a forgery are manageable and other checks exist.
Where the consequences are not manageable, they ask for a copy whose authenticity somebody has staked their professional standing on. That is what certification is: a named third party stating, in writing, that the copy in front of you matches an original they examined.
It follows that you cannot certify your own statement, and no service can sell you certification of a document it has not seen alongside its original. If a process does not involve a third party examining something, whatever it produces is not certification, whatever it is called.
The four documents people mean
Ask which of these is required before you go anywhere. They differ in who signs, what it costs, and how long it takes.
| Document | Who attests it | Typically wanted for |
|---|---|---|
| Bank-stamped statement | The bank itself, with a branch stamp and often a signature | Visa applications, tenancy, and most routine requests. The commonest answer by far |
| Certified copy | A solicitor, accountant, or other person in a recognized profession | Applications where a professional attestation is specified, and where the bank will not stamp |
| Notarised copy | A notary public, under seal | Cross-border matters, and anything that will be relied on in a legal proceeding |
| Apostilled document | A government authority, certifying the notary's authority | Use in another country that is party to the Hague Apostille Convention |
The list runs from cheapest and fastest to most expensive and slowest. An apostille is built on a notarisation, which is built on an original, so starting at the wrong end wastes both money and time.
Getting one from your bank
The bank-stamped version covers most requests. Practice varies between institutions and between countries, so treat this as the shape of the process rather than a guarantee.
-
Ask what is actually required, in writing
Whoever asked for a certified statement will name what they will accept: a branch stamp, a professional's certification, or a notarisation. This one question decides everything that follows.
-
Ask the bank for a stamped statement for the period
Many banks do this at a branch counter while you wait. Some handle it through a request in online banking or a telephone line, and some post it. Business accounts often have a different route from personal ones.
-
Check what the stamp actually says
A stamp confirming the branch and the date is what is usually wanted. A stamp saying only that the document was printed at that branch is weaker, and some assessors reject it. It is worth reading before you leave.
-
Go to a professional or a notary only if the bank cannot help
Where the bank will not stamp, a solicitor or accountant certifying a copy against the original is the next step, and a notary after that. Both charge, and both need to see the original rather than a copy you bring.
Things worth knowing before you go
Each of these is a reason certified statements come back rejected.
- Certification has a shelf life in practice
- The attestation does not expire, but the assessor's requirement usually specifies a recency, commonly within the last 3 months. A certified statement from last year is a certified copy of an old statement, which is not what was asked for.
- Every page usually needs the stamp
- A stamp on the first page of a 6-page statement is frequently rejected. Ask for all pages, and check them before you leave the branch.
- Digital banks may have no branch to stamp anything
- Where an institution has no branches, ask what it offers instead. Some issue a signed letter or a statement with a verification reference; some offer nothing, and the professional certification route is the only one available.
- A charge is normal
- Banks commonly charge per statement or per page for this, and professionals charge for their time. It is worth confirming the fee before requesting a long run of months.
- A certified copy is not a converted copy
- Certification attests to the document. Extracting the transactions into a spreadsheet produces a different artefact that carries none of that standing, and no assessor treats one as the other.
Where converting a statement fits, and where it does not
A converted statement cannot be certified. Certification confirms that a copy matches an examined original. Extracted transactions are data from the statement, not a copy.
The two do different jobs and they are not substitutes. Send the certified statement where authenticity is what is being tested. Use the extracted rows where the transactions themselves are the point, such as reconciling, categorising, or getting the figures into accounting software.
It is common to need both from the same document, and there is no conflict in that. The certified PDF goes to the assessor and the extracted rows go into your books.
Questions people ask
What is a certified bank statement?
A copy of a statement that a third party with standing has attested is a true copy of the original. In practice the phrase covers four different documents: a bank-stamped statement, a copy certified by a professional, a notarised copy, and an apostilled one. Asking which is required saves a wasted trip.
How do I get a certified bank statement?
Ask your bank for a stamped statement for the period you need, which many branches produce while you wait. Where the bank will not do it, a solicitor or accountant can certify a copy against the original, and a notary after that. Confirm what your assessor will accept before you start.
Can I certify my own bank statement?
No. The value of certification is that somebody independent has staked their professional standing on the copy matching the original, so a self-certified statement is a contradiction. Any process that does not involve a third party examining the document produces something other than certification.
Is a stamped statement the same as a notarised one?
No. A stamp comes from the bank and confirms the branch and the date. A notarisation comes from a notary public under seal and carries more weight, particularly across borders. An apostille sits above both and certifies the notary's own authority for use in another country.

- Statements from a closed account When the months you need are from an account you no longer hold.
