UK Companies House
The Registry
What is Companies House?
Companies House is the official UK government agency responsible for registering and maintaining a public record of all companies in England, Wales, Scotland, and Northern Ireland. It was established in 1844, as part of the Companies Act of that year. From the beginning, its main purpose was to provide greater transparency and information about companies, making it easier for investors and other stakeholders to understand their operations and financial health.
According to the Companies House blog, their function includes incorporating and dissolving limited companies, registering the information companies are legally required to supply, and making that information available to the public with major Economic Crime and Corporate Transparency Act (ECCTA) reforms from 2023-2026 enhancing verification, enforcement powers (e.g., fines up to £10,000 without court), and data accuracy.

What information is available through Companies House?
There are more than 4 million limited companies registered in the UK, and over 500,000 new companies are incorporated each year and added to Companies House.
Key entity types listed in the registry include:
- Private Limited
- Private Limited by Guarantee/No Share Capital
- Limited Partnership (now facing stricter rules from early 2026: mandatory annual confirmation statements, ACSP filings via accountants/solicitors, no PO boxes for addresses, with 6-month transition)
- Limited Liability Partnership
- Private Limited by Guarantee/No Share Capital/(Use of Limited Exemption) (plus new requirements for full shareholder lists/names in confirmation statements)
On these companies, Companies House provides details about their registered address, directors, shareholders, and People with Significant Control (PSCs). Called a “beneficial owner” in other jurisdictions, a person with significant control is someone who owns or controls a specific company. Companies House requires that all registered companies identify their PSCs and now publicly displays their verification status.
The UK registry also provides access to the following company documents:
- Certificate of Incorporation Confirmation statement (CS01) – Used to confirm that the company details are up to date.
- Annual Returns
- Return of allotment of shares (SH01) – Used to give notice of shares allotted following incorporation.
- Notification of purchase of own shares (SH03) – Used to give notice of a purchase by a limited company of its own shares.
- Notification of cancellation of shares (SH06) – Used to give notice of a cancellation of shares by a limited company on purchase.
Accessing the Registry
How can you access Companies House?
Companies House is accessible online through their website, where you can search for information about specific companies by name, company number, or other criteria. You can also download company information in bulk, or submit electronic filings.
The website also offers a variety of other services, such as the ability to change company details, file annual returns, and change company officers.
IDV Requirements
What are the new ID Verification requirements for Companies House?
Despite its importance and usefulness, Companies House has also received negative media scrutiny over the past few years due to its historically poor data verification.
As an enormous repository of information with no enforcement powers, Companies House hasn’t been able to prevent companies from providing false information. These, in turn, could be used to facilitate money laundering schemes or circumvent sanctions, especially since the Russian attacks on Ukraine in February 2022.
To address such concerns, the phased rollout began on 18 November 2025 (previously announced December 2022) with new directors/PSCs/LLP members verifying immediately via GOV.UK One Login, Post Office, or ACSPs; existing individuals have until next confirmation statement (up to November 2026), after which unverified filings face rejection, fines, or strike-offs.
While details on these new requirements are still scarce, the UK registry is aiming to provide various options to facilitate a seamless identification procedure for users.
According to the official statement, it will be possible verify directly with Companies House or through an Authorised Corporate Service Provider (ACSP).
Direct verification with Companies House will primarily rely on a standard digital service for ID verification, linking a person with their government-issued ID such a passport or a driving license. For people who are not able to access the digital service, alternative methods will be provided as well.
If choosing the ACSP route, it will be necessary to involve an intermediary such as a company formation agent, an accountant, or a legal adviser. To limit money laundering risks and increase liability for ACSPs, intermediaries will have to be registered with a supervisory body and already be subject to due diligence and Know Your Customer (KYC) requirements on all of their clients.

ID Verification Deadline Approaches in November 2026
The 12-month transition period began after the November 2025 rollout, requiring existing directors, LLP members, and PSCs to verify identities with Companies House before their next confirmation statement—up to November 2026.
Failure to verify risks filing blocks, fines up to £10,000, or strike-offs under ECCTA powers.
Know Your Customer’s new dashboard flags instantly show verified vs unverified status from filings, cutting manual KYB checks by up to 85% during this window.

Implications for ACSPs
What does the New ID Verification requirement mean for ACSPs?
The new requirements will have potentially great implications for ACSPs. (third-party filers like accountants must register—AML-supervised—with public register; deadline delayed from spring to no earlier than November 2026, prioritising director/PSC verification first).
In order to form new companies or file company information, these intermediaries will need to register and confirm their own AML supervised status with Companies House. To protect themselves against enforcement action down the line, ACSPs will also need to complete all the necessary identity verification checks on their clients and their beneficial owners before completing any filings.
