Certified Company Documents in the United Kingdom
Prepare Certified Company Documents for a company formation, banking, KYB, supplier onboarding or international verification file in United Kingdom: what it proves, when it is accepted, what to check and where to verify the official source.
What is Certified Company Documents?
Certified Company Documents is used to prove an official company-registration fact before a third party relies on the business identity. It may be requested during company setup, account opening, investor checks, platform onboarding, supplier due diligence or cross-border administration.
This page targets certified copies and certificates, while the existing incorporation certificate page targets the basic incorporation document itself.
Many rejected files use a tax number, a private template, a screenshot or an old registry document when the requester wanted official company proof. The first step is to identify the exact document type and issuing authority.
When this document is useful
| Situation | Usefulness | What to verify |
|---|---|---|
| Business bank account | High | Bank files often require legal name, registry number, status and current evidence. |
| KYB / supplier onboarding | High | The requester usually checks registry data against ownership, address and tax records. |
| Cross-border use | High | Certification, notarisation, apostille or legalisation may be required. |
| Tender or platform verification | Medium | The file should show the document date and a registry source check. |
| Internal admin | Medium | A current extract or register search may be enough if certified evidence is not required. |
Do not confuse company proof, tax proof and governance documents
| Document | What it proves | When to use it |
|---|---|---|
| Certified Company Documents | Proves the document or registry fact requested in the file. | Use when the requester asks for incorporation, existence, status or current company evidence. |
| Company register search | Lets you verify current official records before relying on the document. | Use before submission to avoid wrong names, old status, stale documents or mismatched numbers. |
| Tax registration document | Proves tax registration, not necessarily company formation. | Attach only if the requester asks for VAT, GST, EIN, ABN, UEN or tax evidence. |
| Articles / constitution / bylaws | Shows internal rules or formation filing content. | Use when governance or founding documents are requested, not as a substitute for current status proof. |
Checks before you submit the file
- Company number and company name match Companies House records
- Requester specifies certified certificate or certified copy
- Legalisation requirements are checked for overseas use
- Free register information is not mistaken for certified evidence
- Requester instructions are checked before paying for a certified or apostilled version.
- All names, dates and reference numbers match the supporting documents.
A document can be genuine and still fail if the company name is old, the status is stale, the wrong registry is used, or the requester needed a certified copy instead of a basic extract.
Where to verify the official source
Use the official registry or authority first. Private services can help with ordering, translation or handling, but the underlying company data should be checked against the official source.

FAQ
What is Certified Company Documents in United Kingdom?
Certified company documents in the United Kingdom are ordered through Companies House when a requester needs official certified evidence, such as a certified certificate or certified copy of a filed document. They are different from simply viewing free company information online.
Is it the same as a tax registration document?
No. A company registration or status document proves a corporate registry fact. Tax documents such as VAT, GST, ABN, EIN or similar registrations prove tax-related registration and may be requested separately.
Should I use an official source?
Yes. Check the document against Companies House or the relevant official registry before relying on it.
Do I need a certified copy?
Sometimes. Banks, investors, foreign authorities and cross-border files may ask for certified, notarised, apostilled or recently issued evidence.
What should match before submission?
The legal name, registry number, issue date, status, address and requester instructions should match the rest of the file.
