uk business structures: a guide for purpose-led founders
A practical introduction to UK business structures, their benefits and trade-offs, and how social enterprises and more fit in.
You know the difference you want your business to make—but which legal structure will support it? UK business structures shape who makes decisions, how you raise money, and what you’re personally responsible for. This guide explains the main options and trade-offs, so you can draw up a shortlist and know what to ask next.
A private company limited by shares (Ltd) is a common route, but it’s not the only option. Whether you’re starting out or reviewing an existing setup, focus on what your organisation needs—not just the label.
legal structure, operating model, and certification: what’s the difference?
Legal structure, operating model, and certification answer different questions. Separating them makes the options easier to compare.
Your legal structure: what is the organisation in law? It affects tax, personal liability, and how you can take money out. Registration requirements vary; not every business registers with Companies House or the Financial Conduct Authority.
Your operating model: how does it work? This covers how you make decisions, involve people, and use profits. Some models involve commitments in your governing documents, not just your branding.
Certification: which standards has it met? Certification, such as B Corp, shows that a business has met the certifying organisation’s requirements. It does not replace the legal structure.
Start with the legal responsibilities you need to manage, then consider how your operating model and any certification will support your purpose.
which uk business structures could suit your organisation?
Compare the options below against three practical needs: personal liability, funding, and control. Each comes with different responsibilities, risks, and potential benefits. Finding the right balance for you and your business is an important step in building a business structure that can grow with you.
sole trader
A simple way to run a business on your own. You and the business are legally the same entity.
Key benefits:
Lower setup burden: Generally simpler and less expensive to establish than a company, although record-keeping and tax-reporting duties still apply.
Full control: You retain control over business decisions and keep all profits after tax.
Key trade-offs:
Unlimited personal liability: Because there is no legal separation between you and the business, you are personally responsible for its debts, so personal assets may be at risk if the business cannot pay.
Ownership & funding limits: Some funders or contracts may require an incorporated structure. A sole trader cannot share ownership or issue company shares without changing structure.
ordinary or general partnership
Two or more people or organisations running a business together for profit. A partnership agreement can set out their roles and responsibilities.
Key benefits:
Shared resources: Partners can pool skills, money, and responsibility for running the business.
Tax on each partner’s share: Each partner generally pays tax on their share of profits. Individuals typically use Self Assessment; corporate partners pay Corporation Tax.
Key trade-offs:
Personal liability: Partners may be personally liable for partnership debts, including debts incurred by another partner. The rules differ across the UK: in Scotland, the firm is a separate legal person and partners can be jointly and severally liable. Check the rules for the relevant jurisdiction.
Vulnerability to disputes: Personal disagreements can disrupt decisions and put pressure on the business, particularly without a clear partnership agreement.
private company limited by shares (ltd)
A company that is legally separate from its owners, who hold shares. It offers limited liability and a way to bring in equity investors.
Key benefits:
Limited liability: Your liability as a shareholder is generally limited to any amount unpaid on your shares. That limit does not cover separate obligations, such as a personal guarantee or liability arising from your own conduct as a director.
Equity investment: A company limited by shares can issue shares to investors, although securing investment depends on the business and the investor’s requirements.
Key trade-offs:
Flexibility over profits and purpose: A standard Ltd can reinvest profits or pay dividends to shareholders, subject to company law and its governing rules. It does not automatically commit assets or profits to a social purpose. You can write that purpose into its articles—the company’s governing rules—but how firmly this commits the company depends on the wording and how those rules can be changed.
Ongoing administration & public records: Companies must file annual accounts and confirmation statements, keep company information up to date, and meet applicable identity-verification requirements. Some company and director information is publicly available.
limited liability partnership (llp)
A partnership with a separate legal identity, registered at Companies House. Members can agree how to share profits and run the business, with limited personal liability.
Key benefits:
Protected partners: Members are generally not personally liable for debts the LLP cannot pay.
Flexible governance: Members can set profit-sharing and management rules in a private LLP agreement.
Key trade-offs:
Transparency vs. privacy: While members' agreements remain private, the LLP must still file public annual accounts.
No company shares: LLPs cannot issue company shares to external equity investors. Funding and ownership arrangements work differently from those of a company limited by shares.
community interest company (cic)
A type of limited company designed to benefit a community, overseen by the CIC Regulator. You must submit a community interest statement explaining who the business will help and how. A compulsory asset lock restricts how you can use or transfer its assets. A private CIC needs at least one director, although its governing rules may require more.
Key benefits:
Clear community purpose: A CIC must pass a community interest test. This gives it a recognised community-benefit framework, but does not guarantee trust or funding.
Protected assets: The asset lock helps keep assets and surpluses dedicated to community benefit. It does not prohibit all payments.
Key trade-offs:
Additional reporting: You must file an annual CIC report explaining how the company has benefited the community, alongside its company accounts.
Investment constraints: The asset lock and limits on certain dividends may make a CIC less suited to investors seeking conventional equity returns or fewer restrictions on distributing profits or selling assets.
company limited by guarantee (clg)
A company with members rather than shareholders. Each member promises to contribute a set amount—often £1—if the company is wound up.
Key benefits:
No shareholder dividends: A CLG has no shares or shareholders, so it cannot pay dividends on shares. Members may still be paid for services, and the constitution determines what can happen to surpluses or assets.
Fit for some community projects: A CLG may suit a grant-funded or community project, but eligibility depends on the funder. It is not automatically a charity or asset-locked.
Key trade-offs:
No share investment: A CLG cannot issue shares. Funding must come from sources such as trading income, grants, member contributions, or borrowing.
No automatic asset lock: Unlike a CIC, a CLG does not have a compulsory statutory asset lock solely because it is limited by guarantee. Any restrictions on distributions or asset transfers depend on its constitution and any separate charitable or regulatory status.
charity
Charity is a legal status, not a single structure. An organisation must have exclusively charitable purposes for public benefit. In England and Wales, common forms include a charitable incorporated organisation (CIO), a charitable company limited by guarantee, a trust, or an unincorporated association. Scotland also has the Scottish Charitable Incorporated Organisation (SCIO).
Key benefits:
Dedicated purpose: Assets and income must support the charity’s purposes, rather than provide profits for its founders.
Tax relief: Charities recognised by HMRC can access tax reliefs and claim Gift Aid on eligible donations, subject to the relevant conditions.
Key trade-offs:
Governance & paperwork: Trustees have legal duties, and charities face accounting, reporting, and regulatory requirements that vary by form, size, and jurisdiction. A charitable company may report to both Companies House and its charity regulator.
Limits on control & returns: Trustees must act in the charity’s interests. This is not a route for founders seeking ownership stakes or a share of profits; personal liability also depends on the legal form chosen.
social enterprises, co-operatives, and b corps: what’s the difference?
These terms describe how a business operates, who owns it, or how it is certified. You can combine some of these approaches with the legal forms above—check the commitments behind each term.
is a social enterprise a legal structure?
No—social enterprise describes a way of doing business. Broadly recognised principles include:
A primary social or environmental mission.
Earning most income through trading, or working towards this.
Reinvesting or donating most profits towards that mission.
Independent, transparent governance that protects the mission.
Social Enterprise UK explains these principles and its membership and certification criteria. Some funders and support bodies also require an asset lock—rules restricting how profits and assets can be used for private benefit—or only accept certain legal structures. Being limited by guarantee does not automatically create an asset lock, so check the requirements of any organisation you hope to approach.
A social enterprise can use several legal structures, including a company limited by shares or guarantee, a CIC, a partnership, or an LLP. Sole traders can also follow this model. When choosing a legal structure for a social enterprise, check how it will protect your purpose and govern the use of profits—not just whether the label fits.
what makes a business a co-operative?
Co-operatives are democratic, member-owned businesses. Co-ops can use several legal forms, such as a co-operative society registered with the Financial Conduct Authority, a company limited by guarantee or shares, or an LLP. One member, one vote is common in co-operative societies, but voting arrangements depend on the legal form and its governing rules. Co-operatives UK explains the different legal forms available.
is b corp a legal structure or a certification?
B Corp is a third-party certification administered by B Lab, not a legal structure. Eligible businesses must meet B Lab’s social, environmental, and governance standards, alongside applicable legal requirements. See B Lab UK’s certification guidance.
how can you narrow down your options?
Use these five questions to turn the options into a shortlist:
Will you work alone, with co-founders, or with a wider membership?
Will income come mainly from customers, grants, donations, or investment?
Do you want to distribute profits to owners or prioritise reinvestment?
How important is protecting the organisation’s purpose over time?
What governance and reporting responsibilities can you realistically manage?
Choose two or three options that appear to fit, then note what you still need to check with a solicitor or accountant. Worth noting, changing your business structure later on can involve legal, tax, and administrative work, and some conversions are restricted.
