Legal forms

Legal formNameMain abbreviationdescriptionCategory
Societas Europaea (la)
Societas Europaea (en)
SE (en)A Societas Europaea registered in the United Kingdom was a European public limited company able to operate across the European Union under one legal form. Following the country's withdrawal from the Union, existing European companies were converted automatically into a domestic equivalent known as a UK Societas, and no new ones can be formed. The designation therefore reflects the position before that change. Shareholders were liable only up to their subscribed capital.Societas Europaea
Private Limited Company (en)
Cyfyngedig (cy)
Pvt. Ltd. (en)A Private Limited Company is the standard corporate form of the United Kingdom, with shareholders liable only for amounts unpaid on their shares. It may not offer shares to the public, and its articles commonly restrict transfers to keep ownership closed. Formation is quick and inexpensive through Companies House, with no minimum capital requirement. It is used by everything from one person businesses to substantial groups.Private Limited Company
Building Society (en)A Building Society is a United Kingdom mutual institution owned by its members, who are its savers and borrowers, and specialising in mortgage lending funded largely by retail deposits. Members have voting rights regardless of the size of their balances, and surpluses benefit members through rates rather than shareholders through dividends. Societies are regulated by the financial authorities and constrained in how much funding they may raise from wholesale markets. Several large lenders remain in this form.
Scottish Charitable Incorporated Organisation (en)This entry records the Scottish Charitable Incorporated Organisation, a corporate form for charities registered with and regulated by the Scottish charity regulator. It gives members and trustees limited liability without the need to register a company, and its assets must be applied to charitable purposes. Filing and reporting are made to the charity regulator. It is widely used by Scottish charities and community bodies.Society
United Kingdom Societas (en)UKS (en)This entry records the United Kingdom Societas, the domestic form into which European companies registered in the country were converted after its withdrawal from the European Union. It retains the share capital and governance features of the former European company without cross-border mobility rights. No new companies of this type may be formed. Existing ones may convert into a public limited company.Economic Interest Group
Government Entity (en)Government Entity in United Kingdom reference data denotes a public body, department or agency of central, devolved or local government. Such bodies exercise public functions and are financed from public budgets, contracting under public procurement rules. Their legal personality varies, with some acting as part of the Crown and others created by statute. Businesses deal with them as customers, funders and regulators.
Charitable Incorporated Organisation (en)This entry records the Charitable Incorporated Organisation, the corporate form for charities in England and Wales registered with and regulated by the Charity Commission. It provides limited liability for members and trustees without dual registration as a company. Its assets must be used for charitable purposes and cannot be distributed. Reporting is made to the charity regulator rather than Companies House.Society
Partneriaeth Atebolrwydd Cyfyngedig (cy)
Limited Liability Partnership (en)
LLP (en)A Limited Liability Partnership is a United Kingdom body corporate that combines the internal flexibility of a partnership with limited liability for its members. Members agree their profit shares and governance in a private members' agreement, and the entity is transparent for tax so profits are taxed in the members' hands. It must file accounts and a confirmation statement at Companies House. Professional firms such as law and accountancy practices are its main users.Partnership
Northern Ireland Company (en)Northern Ireland Company denotes a company registered in Northern Ireland, which since the harmonisation of company law forms part of the same United Kingdom register while retaining separate historic legislation for some purposes. Such companies are subject to the same company law framework as those in Great Britain. Certain society and charity forms remain governed by distinct Northern Ireland legislation. The label identifies the place of registration rather than a distinct legal form.
Private Unlimited Company (en)A Private Unlimited Company is a United Kingdom company whose members have no cap on their liability for its debts if it is wound up with a shortfall. In exchange it is generally exempt from filing accounts at Companies House, which appeals to owners who value confidentiality. It is used within group structures where a solvent parent stands behind the entity. Creditors ultimately have recourse to the members.Private Unlimited Company
Royal Charter Company (en)A Royal Charter Company is a United Kingdom body incorporated by royal charter rather than by registration under the Companies Acts. Universities, professional institutes, learned societies and some historic corporations hold this status, which confers legal personality and a defined constitutional framework. Changes to a charter require approval through the Privy Council. Such bodies are typically non-commercial and long established.Unknown
Industrial and Provident Society (en)IPS (en)An Industrial and Provident Society was the historic United Kingdom form for cooperatives and community benefit organisations, covering member owned trading societies and bodies conducting business for the benefit of the community. The category was renamed and reorganised into registered societies, comprising cooperative societies and community benefit societies. Registration lies with the financial services regulator rather than Companies House. Existing societies continue under the modern framework.Society
Other company type (en)Other company type is a residual heading in United Kingdom company data for entities that do not correspond to one of the standard registered forms. It signals that the register has not classified the entity rather than describing a structure. Users should consult the register entry to establish the actual form and liability regime. No conclusion about liability can be drawn from the label alone.Unknown
Registered Society (en)A Registered Society is the modern United Kingdom form for cooperatives and community benefit societies, registered with the financial services regulator. A cooperative society is run for the benefit of its members, while a community benefit society conducts business for the wider community and may have an asset lock. Members typically have one vote each regardless of shareholding. The form is used by cooperatives, housing associations, community energy schemes and social clubs.Society
Old Public Company (en)An Old Public Company is a United Kingdom company that was a public company under earlier legislation but did not re-register under the modern rules for public limited companies. Such companies cannot offer shares to the public and are subject to restrictions until they re-register or convert. The category is a legacy of company law reform. Very few such companies remain.Public Company
Public Limited Company (en)PLC (en)A Public Limited Company is the United Kingdom form entitled to offer its shares to the public and to seek a listing. It requires a minimum share capital of which a quarter must be paid up, at least two directors and a company secretary, and it faces stricter disclosure and audit obligations. Shareholders are liable only for amounts unpaid on their shares. It is the form used by listed companies and large enterprises.Public Limited Company
Friendly Society (en)A Friendly Society is a United Kingdom mutual organisation owned by its members and providing savings, insurance and welfare benefits. Such societies grew out of the tradition of mutual self-help before the welfare state and continue to offer life assurance, savings plans and health cover. Members control the society democratically and surpluses benefit them rather than outside shareholders. They are registered and supervised by the financial authorities.
Co-operative Society (Northern Ireland) (en)Co-op (en)A Co-operative Society in Northern Ireland is a member owned trading society registered under Northern Ireland societies legislation. Members control it democratically, typically with one vote each, and share in surpluses according to their trade with the society rather than their capital. Retail, agricultural and credit cooperatives use the form. Registration lies with the Northern Ireland registrar or the financial services regulator depending on the type.
Converted/Closed (en)Converted or closed is a status heading in United Kingdom company data indicating that an entity has been converted into another form or has ceased to exist. It reflects the state of the register entry rather than a legal form. Users should look to the successor entity or the dissolution record for the current position. No trading conclusions should be drawn from such a record without further checks.Unknown
Private Unlimited (en)Private Unlimited denotes a United Kingdom private company whose members have no cap on liability for its debts on a winding up. In exchange the company is generally exempt from filing accounts publicly, which is its main attraction. It appears in group structures where a solvent parent stands behind the entity and values confidentiality. Creditors ultimately have recourse to the members.
Other Type of Company (in Northern Ireland) (en)This category covers other types of company registered in Northern Ireland that do not correspond to the standard forms. It reflects the legacy of separate Northern Ireland company and society legislation. Users should consult the register entry to establish the actual structure and liability regime. The heading carries no substantive meaning on its own.
Private Fund Limited Partnership (en)PFLP (en)A Private Fund Limited Partnership is a United Kingdom limited partnership designated for use as a private investment fund. The designation removes several formalities that suited trading partnerships, including certain capital contribution and registration requirements, and it gives limited partners a statutory list of activities they may undertake without losing limited liability. It is the standard structure for private equity and venture capital funds established in the country. A general partner manages the fund and bears unlimited liability.
Protected Cell Company (en)This entry records the Protected Cell Company, a United Kingdom entity divided into legally segregated cells whose assets and liabilities are ring fenced from one another. A creditor of one cell cannot reach the assets of another, which allows several risk pools or strategies to share one legal shell. It is used mainly in insurance and investment structures. Contracts must identify the specific cell that is engaging.Unknown
Co-operative Society (en)Co-op (en)A Co-operative Society in the United Kingdom is a registered society run for the benefit of its members, who are typically its customers, workers or producers. Members control it democratically with one vote each regardless of shareholding, and surpluses are distributed according to trade with the society. Retail, agricultural, worker and housing cooperatives use the form. Registration and supervision lie with the financial services regulator.
Assurance Company (en)Assurance Company in United Kingdom reference data denotes an insurer, particularly one writing life assurance and long term savings business. Such companies are authorised and supervised by the prudential and conduct regulators and must meet solvency and conduct requirements. They may be organised as companies limited by shares or as mutual bodies owned by policyholders. The designation reflects the regulated activity rather than a distinct company form.
Societas Cooperativa Europaea (en)SCE (en)A Societas Cooperativa Europaea registered in the United Kingdom was a European cooperative society, allowing cooperative members from several member states to operate under one European framework. Following the country's withdrawal from the European Union, existing societies were converted into a domestic equivalent and no new ones can be formed. The designation reflects the position before that change. Members' liability was limited to their subscribed capital unless the statutes provided otherwise.Limited Co-operative Society
Private Unlimited/No Share Capital (en)Private Unlimited with no share capital denotes a United Kingdom private company that has neither share capital nor any limit on the liability of its members. Membership rather than shareholding determines participation, and members must meet the company's debts on a winding up. Reduced filing obligations are the main practical advantage. It is a rare form found in professional and group structures.
United Kingdom Economic Interest Grouping (en)UKEIG (en)This entry records the United Kingdom Economic Interest Grouping, the domestic successor to the European Economic Interest Grouping after the country left the European Union. It enables businesses to cooperate on activities supporting their own operations, with results accruing directly to the members. Members remain jointly and severally liable for its debts. Existing European groupings in the country were converted into this form.Economic Interest Group
Investment Company with Variable Capital (en)This entry records the Investment Company with Variable Capital, the United Kingdom open-ended corporate fund whose capital varies with subscriptions and redemptions. It is authorised by the financial regulator, managed by an authorised corporate director and has its assets held by a depositary. Investors hold redeemable shares in the company itself. It is one of the principal structures for United Kingdom retail funds.Investment Company
Community Benefit Society (Northern Ireland) (en)BenCom (en)A Community Benefit Society in Northern Ireland is a registered society that conducts business for the benefit of the wider community rather than only its members. It typically carries a statutory asset lock preventing assets from being distributed for private gain. Community shops, pubs, housing and energy projects commonly use the form. Registration lies with the financial services regulator under Northern Ireland legislation.
Unregistered Company (en)An Unregistered Company in the United Kingdom is a body corporate created other than by registration under the Companies Acts, such as by statute or royal charter, to which certain company law provisions are applied by regulation. This ensures a minimum level of disclosure and accountability despite the unusual mode of incorporation. Such entities are relatively rare. Their powers derive from the instrument that created them.
General partnership (en)GP (en)A General Partnership in the United Kingdom arises when two or more persons carry on business in common with a view to profit. In England and Wales it has no separate legal personality, and every partner is jointly liable for the debts of the firm without limit. There is no registration requirement beyond tax and, where applicable, business name rules. It is used by small businesses and professional practices.General Partnership
Community Benefit Society (en)BenCom (en)A Community Benefit Society is a United Kingdom registered society that trades for the benefit of the community rather than only for its members. It usually adopts a statutory asset lock so that its assets cannot be distributed for private gain, which supports community ownership projects. Community shops, pubs, renewable energy schemes and housing bodies commonly use it. Registration and supervision lie with the financial services regulator.
Limited partnership (en)LP (en)A Limited Partnership in the United Kingdom consists of at least one general partner who manages the business and is liable without limit and one or more limited partners whose exposure is capped at their contribution. Limited partners must not take part in management to preserve that protection. It must be registered at Companies House. It is the standard vehicle for private equity and venture capital funds.Limited Partnership
Sole proprietorship (en)SP (en)A Sole Proprietorship in the United Kingdom, commonly called a sole trader, is a business carried on by one individual without a separate legal entity. The owner keeps all profits, reports them as personal income and is personally liable for every obligation of the business. Registration is limited to notifying the tax authority and observing business name rules. It is the simplest and most common way to start a business.Sole Proprietorship
Unincorporated Association (en)An Unincorporated Association in the United Kingdom is a group of people bound by a common purpose and a set of rules but without separate legal personality. It cannot own property or contract in its own name, so officers and trustees act on its behalf and may be personally liable. Clubs, societies and small community groups commonly operate in this way. Growing organisations usually incorporate to obtain limited liability.
Credit Union (Northern Ireland) (en)A Credit Union in Northern Ireland is a member owned cooperative that provides savings and loans to a defined common bond of members. Credit unions are especially well established in Northern Ireland, with a large share of the population as members. They are regulated by the financial authorities with deposit protection for members' savings. Surpluses are returned to members as dividends on savings or rebates on interest.
European Economic Interest Grouping (en)EEIG (en)A European Economic Interest Grouping registered in the United Kingdom allowed businesses from different member states to cooperate on shared activities. Following the country's withdrawal from the European Union, existing groupings were converted into United Kingdom economic interest groupings and no new ones can be formed. Members remained jointly and severally liable for the grouping's debts. The designation reflects the position before that change.Economic Interest Group
Credit Union (en)A Credit Union in the United Kingdom is a financial cooperative owned by its members, who must share a common bond such as an employer, locality or association. It provides savings accounts and affordable loans, with surpluses returned to members rather than to outside shareholders.

Scottish Partnership (en)This entry records the Scottish Partnership, a partnership under Scots law that possesses separate legal personality distinct from its partners. It may own property, contract and sue in its own name while partners remain jointly and severally liable for its debts. This distinctive feature makes it useful in certain fund and holding structures. It is governed by partnership legislation as applied in Scotland.General Partnership
Community interest company (en)CIC (en)A Community Interest Company is a United Kingdom company created for social enterprises, combining ordinary company structures with a statutory asset lock and limits on the distribution of profits and assets.

The sixth character represents the decade of birth, for example 8 for the 1980s. The characters seven to eleven encode the date of birth in the form MMDDY, where MM is the month of birth, with female drivers adding 5 to the first digit so that January ranges from 51 to 62, DD is the day of birth and Y is the last digit of the year of birth. Characters twelve and thirteen are two additional letters or digits, often an issue number or another identifier. The last five characters, positions fourteen to eighteen, are a numeric sequence containing a check digit that confirms validity.

Invalid checksum of EU VAT ID UK (United Kingdom)
ACCURACY
GB (United Kingdom of Great Britain and Northern Ireland) This rule verifies the checksum of the European VAT number in the United Kingdom. For the standard nine-character format the eighth and ninth digits are the check digits.

R1 is the remainder, modulo 97, of 8 times C1 plus 7 times C2 plus 6 times C3 plus 5 times C4 plus 4 times C5 plus 3 times C6 plus 2 times C7 plus the two-digit value formed by C8 and C9. R2 is the same expression with 55 added, again modulo 97. Either R1 or R2 must be zero for the number to be valid.

Two restrictions apply to the ranges of the identifier. For the MOD97 variant the number must not fall in the ranges 0100000 to 0999999, 9490001 to 9700000 or 9990001 to 9999999. For the MOD9755 variant it must not fall in the ranges 0000001 to 0100000 or 0100001 to 1000000.
