Choosing a Legal Structure for a New Community Charity: CIO, Trust, or Unincorporated
Most small community groups start out as an informal committee. The moment they want a bank account, a grant, or protection from personal liability, that informality becomes a problem worth solving properly.
Published July 2026A new committee raising money for a local cause — a playground, a memorial event, a village hall repair fund — can operate for a surprisingly long time without any formal legal structure at all, simply as a group of people with a shared purpose and a bank account held in someone’s name. That arrangement works until it does not: a grant funder wants to see a governing document, a bank refuses to open an account without one, or someone asks, reasonably, what happens to leftover funds if the group folds. At that point, choosing a proper legal structure stops being optional.
Unincorporated association: the simplest starting point
An unincorporated association is the loosest option and the one most small community groups begin life as, whether or not they realise it. It requires only a constitution — a written document setting out the group’s purpose, how committee members are chosen, and how money is handled — and no registration with any external body unless income crosses the threshold that requires charity registration. The major drawback is that an unincorporated association has no legal existence separate from its members: contracts are signed by individuals personally, and in principle those individuals carry personal liability for the group’s debts and obligations. For a group running occasional small events with modest sums involved, this risk is usually manageable. For anything larger, or anything involving a lease, employees, or significant contracts, it becomes a real exposure.
Charitable trust
A charitable trust is an older legal form, historically common for groups managing a specific fund or asset — a memorial fund, a piece of land, an endowment — on behalf of a stated charitable purpose. Trusts are administered by trustees under a trust deed, and like unincorporated associations they traditionally have no separate legal personality, meaning trustees can in principle be personally liable for the trust’s obligations. Trusts remain a sensible structure for holding a specific asset with a narrow, stable purpose, but they are less commonly recommended today for community groups running varied ongoing activity, since better-protected structures now exist for that purpose.
Charitable Incorporated Organisation (CIO)
The CIO was introduced specifically to give smaller charities a simpler alternative to setting up as a full company limited by guarantee, while still providing legal personality separate from its trustees and members. A CIO can enter contracts, own property, employ staff, and sue or be sued in its own name, and its trustees generally have limited liability, protected from personal responsibility for the organisation’s debts provided they have acted properly and within their duties. Registration is with the Charity Commission rather than Companies House, which keeps the administrative burden lighter than the company-plus-charity dual registration that used to be the only route to incorporated charitable status.
For a community group anticipating grant funding, contracts, insurance policies in its own name, or simply wanting the peace of mind that comes with limited liability, a CIO is now generally the recommended default, and it has become the most common new charitable structure registered in England and Wales in recent years for exactly that reason.
Company limited by guarantee
Some community organisations, particularly those running more substantial commercial activity alongside their charitable purpose — a community shop, a managed community centre with trading income — still choose to incorporate as a company limited by guarantee and separately register as a charity. This route brings the added complexity of dual regulation, under both Companies House and the Charity Commission, but suits organisations with more complex financial and operational structures than the simpler CIO model was designed to handle.
Making the choice
For most new community groups in the fundraising and events space — the kind that run a village fete, a sponsored walk, or a candlelit charity evening — the practical choice usually comes down to unincorporated association for the smallest, most occasional activity, or a CIO once the group is handling meaningful sums, taking on any contractual risk, or wants to apply for grants that specifically require a formal charitable structure. The Charity Commission’s own guidance on setting up a charity sets out the current registration thresholds and model governing documents for each structure, and is worth reading in full before a committee commits to one option over another, since the right choice depends heavily on the specific scale and risk profile of what the group actually does.
