Unincorporated association

An unincorporated association is a creature of common law and contract. Two or more people agree to come together for a shared purpose and to be bound by the rules they adopt (the constitution). That contract is the association.

Crucially, the association has no legal personality of its own. It cannot:

• Hold property in its own name
• Enter contracts in its own name
• Sue or be sued in its own name
• Employ staff in its own name (technically)

Property is held by named individuals — often called “holding trustees” — on behalf of the members. Contracts are signed by individuals who are personally liable unless the other party agrees otherwise.

Two ingredients:

1. Two or more members willing to be bound by the rules.
2. A written constitution setting out the name, purposes, how members are admitted, how the committee is elected, how meetings work, how funds are spent, and how the association is wound up.

That's it. There is no register to join, no regulator to satisfy, no fee. The Charity Commission publishes a model constitution (CC22a) for charitable unincorporated associations which is a sensible starting point even if you don't ultimately register as a charity.

In practice, banks now expect to see a constitution before they open a community account, so even informally-run groups end up writing one.

An unincorporated association whose purposes are exclusively charitable (within the meaning of the Charities Act 2011 s.3) must register as a charity with the Charity Commission once its annual income exceeds £5,000. This is mandatory, not optional. The £5,000 threshold has been in place since 2007 and was reviewed in 2025; a proposal to raise it to £10,000 was rejected.

Below £5,000 income, a charitable unincorporated association is still a charity in law — it has charitable purposes and operates for public benefit — but registration is not required. It can still claim gift aid (HMRC charity status is separate from Charity Commission registration; small charities can register with HMRC directly for tax purposes).

Associations with non-charitablepurposes (some campaign groups, some clubs primarily for members' benefit) never register with the Charity Commission, regardless of income. They are taxed by HMRC as a corporation tax body on income outside the mutual trading principle.

The shape of organisation an unincorporated association suits:

• Very small — income under £5,000 a year, no employees, no premises, no leases.
• Short-lived — a time-limited campaign, a one-off project, a planning-application group.
• Low risk — no activities involving children or vulnerable adults, no physical risks to participants, no fundraising at scale.
• Member-focused— residents' groups, hobby clubs, friendly societies in the colloquial sense.

For organisations of this size, the time and cost of incorporation outweigh the protection it provides.

Any of the following typically tips the balance in favour of becoming a CIO (or, in some cases, a CIC):

• Income passes £5,000 a year with charitable purposes — registration becomes mandatory anyway.
• You're holding more than ~£10,000 in funds against unlimited personal liability — incorporation usually becomes worth the modest effort.
• You're about to take on a lease, employ someone, sign a long-term contract, or accept a restricted grant of any size. A landlord, employee or grant funder is now exposed to the individuals who signed.
• You're acquiring property — incorporation is essentially required, because property otherwise has to be held by named individual trustees on trust, with all the transfer paperwork every time a trustee changes.
• You're running an activity with real physical risk — sports, outdoor expeditions, events involving large crowds, activities with vulnerable adults or children.

See UK community group legal structures compared for the options once you decide to incorporate.

Unlike a charitable company or a CIC, there is no statutory conversion from an unincorporated association to a CIO. The process is:

1. Form a new CIO with the same charitable purposes (registration with the Charity Commission, typically 30–60 days).
2. Transfer the assets from the unincorporated association to the new CIO by a deed of gift (cash, equipment, any leases or contracts that the other party will agree to novate).
3. Wind up the old association in accordance with its constitution.
4. Register the mergeron the Charity Commission's Register of Mergers under Charities Act 2011 s.305 — this preserves entitlement to future legacies left to the old association.

Total elapsed time: typically 3 months. The most fiddly part is usually getting banks, landlords and contract counter-parties to agree to novate or assign the existing arrangements.

Banking. Most banks will open a community account on production of the constitution and id checks on the signatories. CAF Bank, Co-op Bank, Unity Trust and Metro Bank are commonly used. Mainstream high-street banks have become more selective in the last few years; expect a multi-week onboarding.

Property. If the association owns land or buildings, the title is held by named individual trustees on trust for the members. Each trustee change requires a transfer at the Land Registry. This is administratively painful enough that it is usually the trigger for incorporation.

Employment. Technically, employees of an unincorporated association are employed by individual committee members jointly. Modern practice is to incorporate before employing anyone for any meaningful period; HMRC and the tribunals have become less indulgent about informal arrangements.

Insurance. Public liability cover is widely available and inexpensive for small unincorporated groups. See public liability for community groups for the basics.
