Companies House is theexecutive agency of the British Government that maintains theregister of companies, employs the company registrars and is responsible forincorporating all forms ofcompanies in the United Kingdom.[3][4]
Prior to 1844, no central company register existed and companies could only beincorporated throughletters patent and legislation. At the time, few incorporated companies existed; between 1801 and 1844, only about 100 companies were incorporated. TheJoint Stock Companies Act 1844 created a centralised register of companies, enabled incorporation by registration, and established the office of the registrar; theJoint Stock Companies Act 1856 mandated separate registrars for each of the threeUK jurisdictions. Initially just a brand, Companies House became an executive agency in 1988.
Allpublic limited,private limited,private unlimited,chartered and some other companies are incorporated and registered with Companies House. The agency also registerslimited partnerships, while most other enterprises fall under the purview of theFinancial Conduct Authority. All limited companies (including subsidiary, small and inactive) must file annual financial statements with Companies House, all of which are public records. The agency is also responsible fordissolving companies.
From 2016, Companies House operated under the authority of theDepartment for Business, Energy and Industrial Strategy. This then became theDepartment for Business and Trade from 7 February 2023 following a Machinery of Government change initiated by Prime MinisterRishi Sunak. The current chief executive is Louise Smyth, who is also registrar forEngland and Wales. The agency, as well asBritish company law in general, is governed by theCompanies Act 2006. As of May 2025,[update] Companies House maintains records of over 5.44 million active companies,[5] including over 5.11 million private limited companies[6] and over 4,000 public limited companies.[7]
Prior to 1844, companies could only beincorporated through grant of aroyal charter, byprivate act of Parliament,[8] or, from 1834, byletters patent. Few companies were incorporated, with only approximately 100 companies being incorporated by private act between 1801 and 1844.[9] At this time, no central register of companies was in existence.
The origins of Companies House date back to 1844, the year theJoint Stock Companies Act receivedroyal assent, enabling companies to be incorporated by registration for the first time.[10] TheAct created the office of the Registrar of Joint Stock Companies to maintain the register of companies,[11] which was publicly accessible.[12] It was hoped byMPs of the day that a publicly accessible central company register would help to protect the public from fraud.[13] All companies, irrespective of their method of incorporation, were obliged to register within three months of thecommencement of the Act.[9]
The Act provided for two types of company registration: provisional,[14] and complete.[15] The filing requirements for complete registration were more extensive than those for provisional registration.[14][15] Given that there was no requirement for companies granted a certificate of provisional registration to submit the remaining information in order to become completely registered, the Act was not hugely successful as many of its provisions applied only to completely registered companies.[16]
The Joint Stock Companies Act 1844 applied only toEngland and Wales, andIreland; it did not apply toScotland.[17]

Prior to the commencement of theLimited Liability Act 1855,shareholders were generally treated similarly to partners in a common lawpartnership, and had unlimited liability for the debts andobligations of the companies in which they heldshares.[18] From 1855, it became possible for shareholders to benefit fromlimited liability[19] as a matter of routine,[20][21] provided the companies in which they held shares were registered with the Registrar of Joint Stock Companies under the 1844 Act.[22] The aim of this act was to incentivise the creation of new joint stock companies, while giving investors, the majority of whom did not play an active role in day-to-day management, protection from liabilities incurred by company directors.[20]
TheJoint Stock Companies Act 1856 abolished the dual registration system of the 1844 Act;[16] provisional registration ceased to be possible. In exchange for providing shareholders with the benefit of limited liability, companies were required to submit certain information to the Registrar for Joint Stock Companies, includingmemoranda andarticles of association (which had not previously been divided in this way),[16] and annual reports.[18]
The 1856 Act also mandated that there be a Registrar of Companies for each of the UK's three jurisdictions.[23] This system remains today, with a separate Registrar of Companies for England and Wales, Scotland, and Northern Ireland;[24] 'Companies House' is merely a brand adopted by the registrars.[25]
Company registration in Scotland commenced in 1856, with the first company registered being theDaily Bulletin Company Limited, a newspaper publisher.[26] The first Registrar of Joint Stock Companies for Scotland was George Deane, from 1856 to 1858, before he was transferred to the London office of Companies House to be Chief Clerk to the Registrar for England and Wales. The remaining staff were transferred to the office of theQueen's and Lord Treasurer's Remembrancer (Q<R), who took on the role of Registrar of Companies for Scotland.
In 1982 the post of Q<R was transferred to theCrown Agent, and the staff and functions relating to company registration in Scotland were transferred to theDepartment of Trade and Industry on 1 April 1981.
In October 1988, Companies House became anexecutive agency of the Department of Trade and Industry, and then in October 1991 started to operate as atrading fund, self-financing by retaining income from charges.
When theCompanies Act 2006 was fully implemented on 1 October 2009, the Northern Ireland companies register was fully integrated into Companies House; previously, all limited companies in Northern Ireland were registered with theDepartment of Enterprise, Trade and Investment.[citation needed]
As government departments were reorganised, Companies House came under theDepartment for Business, Enterprise and Regulatory Reform (2007), theDepartment for Business, Innovation and Skills (2009), and theDepartment for Business, Energy and Industrial Strategy (2016). Companies House was a member of thePublic Data Group, an advisory board which between 2011 and 2015 sought to improve public access to government data.[27]
Companies House is also responsible fordissolving companies.[28]
In 2020, there were approximately 4.3 million businesses on the Companies House register.[29] In the same year Companies House ceased to operate as a trading fund.[30]

In view of thecoronavirus pandemic, from 25 March 2020 companies were able to apply for a three-month extension to the annual deadline for filing their accounts and reports.[29] TheCorporate Insolvency and Governance Act 2020 made this extension automatic for filing deadlines between 27 June 2020 and 5 April 2021; after the latter date, companies could again apply for a three-month extension.[38] There were also temporary extensions to the deadlines for filing confirmation statements and certain event-driven filings.[39]
TheEconomic Crime and Corporate Transparency Act 2023, receiving royal assent on 26 October 2023 and coming into force on 4 March 2024, signified a major legislative reform for Companies House. The act aims to transform Companies House from a mere repository of documents into an entity that proactively supervises company registration procedures and plays a role in preventing economic crimes.[40] Central to the act is the requirement for identity verification of individuals wishing to incorporate a company, including directors,people with significant control, and members of limited liability partnerships; this applies to such individuals, both new and existing. In April 2025, Companies House started identity verification on a voluntary basis and from 18 November 2025, any company director or person with significant control must confirm their identity directly with the government or via an authorised corporate service provider.[41]
The role of Registrar of Companies is not a political one, and the incumbent is acivil servant.

The Registrar of Companies forEngland and Wales is located inCardiff,[42] and is responsible for the registration of companies in England and Wales. Until 2011 there was another office inNantgarw, Wales. The London office atPetty France is purely a facility to file and view documents, which are then processed in Cardiff.
The Registrar of Companies for Scotland, is based at Companies House,Edinburgh, and is responsible for the registration of companies in Scotland. The current registrar is Lisa Davis.[4]
The Registrar of Companies for Northern Ireland is based at Companies House,Belfast, and is responsible for the registration of companies in Northern Ireland. The current registrar is Lynn Cooper.

Companies House does not act as registrar for the following undertakings:
The Register of Companies is the index of every undertaking registered with Companies House.[64]
Every undertaking registered with Companies House must have a unique name.[25] Whether a name is unique or not is determined by Companies House; certain terms and punctuation, and characters after the first 60, are completely disregarded when assessing the uniqueness of a name, and other characters, although strictly different, are deemed to be the same as each other.[65]
Companies may not have names which if used would constitute a criminal offence, or which are offensive.[66] Approval from theSecretary of State is required if a company wishes to use a name indicating a connection to government,[67] or other so-called 'sensitive' words or phrases.[68]
Generally, undertakings registered with Companies House are required to indicate their legal form in their names:
Notwithstanding the above, private limited companies need not indicate their legal form in their names if they arecharities,[83] exempted by newregulations made by the Secretary of State,[84] or subject to a continuing exemption.[85]
Every undertaking registered with Companies House is issued with a registered number.[86] Once issued, a registered number remains the same, even if the undertaking changes its name.[25]
Registered numbers consist of eight digits, and in certain circumstances a two letter prefix, including:[87]
The Register of Companies containscertificates of incorporation for all undertakings incorporated by registration with Companies House. Incorporation takes place on the issuance of a certificate of incorporation by the registrar.[88] Private limited companies can be issued with a certificate of incorporation within 24 hours of an application being submitted.[89]
Certificates of incorporation for companies include the following information:[90]
Registration of companies is complete once the certificate of incorporation is signed orsealed by the registrar.[91]
Certificates of incorporation for limited liability partnerships include the following information:[92]
Incorporation of a limited liability partnerships is complete once the certificate of incorporation is signed or sealed by the registrar.[93]
Limited partnerships are not issued with certificate of incorporation upon registration with Companies House, but instead with certificates of registration.[94] This is because limited partnerships are notlegal persons and therefore are not created by incorporation.[95]
Certificates of registration include the following information:[96]
A limited partnership comes into existence once its certificate of registration has been signed or sealed by the registrar.[97]
Companies House does not verify the accuracy of information filed.[98] The Department for Business, Energy and Industrial Strategy announced in 2020 that Companies House would be given powers to verify the identities of company directors,[99] but did not set a timetable for their introduction.[100]
Since June 2016, private companies can elect to keep certain statutory records on the central register which is held and published by Companies House, instead of maintaining their own registers.[101] These records include:[102]
In February 2008,The Times[103] andComputer Weekly[104] broke a story that almost 4,000 of the names on the Companies House register of directors were on international watchlists of alleged fraudsters, money launderers, terror financiers and corrupt officials. The results came fromDatanomic who had screened the 6.8 million names on the register against a World-Check database of high risk individuals and businesses. The exercise also revealed more than 1,500 disqualified company directors were being allowed to run other UK companies as Companies House was not checking names against its register of disqualified persons.[103]
