Updated on 9 November 2026 by Nicolas Finet, CEO of Sortlist. This guide has been rewritten for the UK: it now covers the legal forms a company can take under UK law, how charities and other organisations are regulated, and the 2025 identity-verification rules at Companies House.
People often use "organisation" (also spelled "organization") and "company" as if they meant the same thing. They do not. A company is one kind of organisation, with a specific legal form and, usually, a profit motive. An organisation is the wider category: any group of people working together towards a shared purpose, from a charity to a government department to a football club.
Key takeaways
- Every company is an organisation, but not every organisation is a company.
- A company is a legal entity, usually set up to make a profit; organisations also include charities, public bodies, clubs and other groups with a shared purpose.
- In the UK, companies register at Companies House under the Companies Act 2006 and, since 18 November 2025, directors and people with significant control must verify their identity.
Organisation vs company: the 6 differences
| Criteria | Organisation | Company |
|---|---|---|
| Legal form | Many forms: charity, trust, public body, association, or a company | Registered company (Ltd, plc, LLP and others) |
| Structure | Varies: trustees, boards, committees, councils | Directors, shareholders or members, and management |
| Ownership | May have no owners (a charity) or members | Shareholders (or members, if limited by guarantee) |
| Leadership | Board, trustees or elected officers | Board of directors and a management team |
| Size | From a volunteer group to a multinational group of companies | One person to thousands of employees |
| Focus | A shared purpose: profit, cause or public service | Commercial activity, normally profit |
What is an organisation?
An organisation is a group of people consciously cooperating towards a common purpose. It has two or more people, some way of dividing tasks and a way of making decisions. It can be a business, a government department or a voluntary group. Large organisations, such as a corporate group, may contain several separate companies.
What are examples of an organisation?
- Companies and corporate groups
- Charities, including charitable incorporated organisations (CIOs)
- Government departments and public bodies
- Educational institutions and universities
- Trade unions and professional bodies
- Partnerships and co-operatives
- Clubs, associations and community groups
Hybrid organisations operate in both the private and public sectors, combining commercial activity with a public mission.
What is a company?
A company is a legal entity formed by people to run a business. It has its own legal personality: it can enter contracts, borrow money, own assets, pay tax and employ people in its own name. The owners' liability is usually limited to what they have invested or guaranteed. In the UK, companies are formed and registered at Companies House under the Companies Act 2006.
Main company types in the UK
| Type | How it works | Typical use |
|---|---|---|
| Private company limited by shares (Ltd) | Owned by shareholders; shares not offered to the public | Most start-ups and small businesses |
| Public limited company (plc) | Can offer shares to the public; must meet higher requirements | Large companies, including listed ones |
| Private company limited by guarantee | Members guarantee a small sum instead of holding shares; profits are not distributed to members | Not-for-profit bodies, clubs, some charities |
| Limited liability partnership (LLP) | A separate legal entity with members rather than shareholders | Professional services firms |
| Community interest company (CIC) | A limited company for social enterprises, with a regulator and an asset lock | Businesses that use their profits for community benefit |
| Unlimited company | Owners' liability is not limited | Rare |
A sole trader is not a company: it is an individual trading in their own name, with no separate legal personality and unlimited personal liability. The same is true of an ordinary partnership.
The company form is popular. According to government statistics, there were 815,277 company incorporations in the UK in the financial year ended March 2026, an increase of 1.67% on the previous year. A typical small business can be incorporated in a day or so, but running one brings annual filing, tax and governance obligations.
Can a company also be an organisation?
Yes: every company is also an organisation. A company can also be part of a larger organisation, such as a group of subsidiaries under one parent, in which companies share skills, services and brand. The organisation can pool resources, while each company keeps its own legal identity, accounts and liabilities. A company can even sit inside a mostly non-commercial organisation, as when a charity sets up a trading subsidiary to run its shops.
The 6 differences in detail
1. Legalities
“From 18 November 2025, identity verification becomes a legal requirement. This date is not a deadline. It marks the start of a 12-month transition period.”
GOV.UK, Changes to UK company law
A company has to register, choose a legal form and file accounts and a confirmation statement every year. Other organisations register under different regimes. A charity in England and Wales registers with the Charity Commission (Scotland and Northern Ireland have their own regulators), and may take the form of a CIO, a trust, an unincorporated association or a company limited by guarantee. A community interest company registers with Companies House and is overseen by the CIC Regulator.
Transparency rules have tightened. From 18 November 2025, identity verification became a legal requirement for directors and people with significant control, under the Economic Crime and Corporate Transparency Act 2023. The date marked the start of a 12-month transition period for existing companies.
2. Structure
A company usually has clear reporting lines: a board of directors, a chief executive or managing director and managers. An organisation can have other structures, such as trustees and a chief executive in a charity, elected councillors and officers in a local authority, or committees and volunteers in a club.
3. Shareholders
A company limited by shares is owned by its shareholders. A plc can offer shares to the public, and may be listed on a stock exchange. Organisations such as charities have no shareholders: any surplus is reinvested in the cause, and a company limited by guarantee does not distribute profits to its members. A corporate group may contain listed companies, but the group itself is not a single listed entity.
4. Leadership
Company directors owe duties to the company under the Companies Act 2006, including promoting its success and acting with reasonable care. Charity trustees owe legal duties to the charity and its beneficiaries. In both cases the board is accountable, but to different stakeholders: shareholders in a company, the cause and the public in a charity.
5. Size
A company can be a single person with a Ltd, or a multinational. An organisation can range from a small volunteer group to a very large body such as a national health service or a global federation. Size alone does not tell you which one you are dealing with.
6. Focus
A company's primary focus is commercial: to create value for its owners through profit. An organisation focuses on its shared purpose, which might be profit, a cause or a public service. Organisations that work closely with local communities often measure success in outcomes rather than financial returns. Social enterprises, such as CICs, sit between the two: they trade like companies but use their surplus for community benefit.
Which should you set up?
- Selling products or services for profit: a private limited company is the usual choice for liability protection and credibility.
- Pursuing a charitable cause: consider a charity form (such as a CIO) and the Charity Commission's registration thresholds.
- Trading with a social mission: a CIC or a company limited by guarantee may fit.
- Testing an idea alone: start as a sole trader, then incorporate when risk or turnover grows.
For legal and tax advice about a specific situation, speak to an accountant or solicitor. If you are building a brand for either kind of body, see brand identity and corporate advertising.
In conclusion
An entrepreneur with a commercial vision will usually form a company, and a group with a shared cause will usually form some other kind of organisation. Both create employment, provide services and drive the economy. What matters is choosing a form that fits your purpose, your liability and your funding.
