Private limited vs PLC: company certificate differences

25 November 2026

A UK private limited company and a public limited company can both need official certificates, but their registered type, filing profile and recipient checklist may differ. Match the certificate to the entity and do not assume a PLC pack is interchangeable with a private-company pack.

Short answer

A UK private limited company and a public limited company can both need official certificates, but their registered type, filing profile and recipient checklist may differ. Match the certificate to the entity and do not assume a PLC pack is interchangeable with a private-company pack. The safe approach is to identify the correct company, document, issue date and recipient requirement before paying for certification or delivery.

What differs

A private company is commonly identified by Ltd and a public company by plc. That distinction can affect wording, constitutional documents and review level. The company number remains the key identifier; use exact registered details rather than a trading brand.

Does the COGS product change

The purpose is similar: a current registered-status snapshot under the applicable route. Content depends on the product and record. Do not promise directors, shareholders, PSCs, signatories or financial information unless specified.

Why PLCs may face more questions

A bank, investor or foreign authority may request articles, accounts, director evidence, listing information or a board resolution. These are recipient due-diligence requirements, not necessarily contents of the certificate.

Incorporation and re-registration

Both types have formation records. If a company re-registers or changes status, preserve the original and later evidence as separate documents. A clear chronology helps a reviewer understand why names or types differ.

Legalisation choices

A recipient may request a COGS, incorporation certificate, articles or certified copies, in paper or electronic form. An apostille does not change a private company into a PLC or prove ownership.

Avoiding group mix-ups

Create a one-page index for each entity showing number, exact name, type, issue date, recipient and legalisation. This is especially useful for PLC parents and private subsidiaries sharing a brand.

Practical checklist

• Use the exact registered company name, number and company type.
• Review the live Companies House record and recent filing history.
• Ask the recipient what the document must prove, how recent it must be and whether it accepts paper or electronic format.
• Confirm apostille, translation, embassy and courier requirements before paying.
• Keep the order confirmation, issued document and legalisation evidence together.
• Index the pack without claiming that a certificate proves ownership, solvency or authority unless it actually does.

Official fees and sources

Check the live GOV.UK guidance on ordering certified copies and certificates from Companies House before ordering. The current working figures for this batch are £22 for a standard Companies House certificate and £65 for a same-day certificate. These are official charges, not an agent’s full service price.

Where legalisation is needed, the live GOV.UK document legalisation guidance lists £45 for a paper apostille, £35 for an e-Apostille, £40 for Next-Day and £100 for Restricted Urgent where the relevant conditions apply. Certification, translation, courier, postage and any later embassy stage can be separate. Do not describe a provider as an FCDO partner unless current official terms expressly support that wording.

Freshness is a recipient rule

There is no universal 90-day legal expiry for every Certificate of Good Standing. About 90 days is a common recipient habit, but a bank, authority or counterparty may specify 30, 60, 180 days or a document issued after a particular filing. An apostille authenticates the relevant signature, seal or status; it does not refresh company information. Check the recipient’s written rule and the live Companies House record before presentation.

Questions to settle before payment

Ask the receiving organisation to confirm the exact document title, the legal entity, the maximum document age and the accepted delivery format. Ask whether it wants an original, a Companies House certified copy, a solicitor-certified copy or an electronic file. If the document will be used outside the UK, ask whether an apostille is enough or whether translation, embassy legalisation or local filing follows. Put the reply in the order file; a short written answer is more useful than an assumption based on a similar transaction.

Also check the practical hand-offs. Who will receive the certificate? Does the bank or authority need the complete pack uploaded in one session? Will it accept a scan for preliminary review and request originals later? Is a courier address different from the registered office? These details affect timing and can prevent a correctly issued document being sent to the wrong place. Keep tracking information and delivery confirmation with the final pack.

Keep the scope clear

A company certificate is one piece of evidence. It should not be described as a guarantee of incorporation history, ownership, financial health, tax compliance, authority to sign or permission to trade unless the document and recipient specifically establish that point. If a reviewer asks a question the certificate cannot answer, add the separate evidence it requests or obtain professional advice. Clear wording protects the client from relying on a document for a purpose it was never designed to meet.

Frequently asked questions

Can a private company use a PLC certificate?

No. The document must relate to the correct entity and type.

Does a PLC COGS prove exchange listing?

No. It is not a market-status document.

Do PLCs always need more documents?

No; the recipient sets its checklist.

Is number more useful than brand?

Yes, especially in a group.

Can an apostille confirm ownership?

No. Ownership evidence is separate.
