How to set up a charitable incorporated organisation in the UK
A corporate legal form made only for charities. You create it by registering with the Charity Commission in England and Wales (or as a SCIO with OSCR in Scotland), not at Companies House. Trustees have limited or no liability and the charity reports once, to its charity regulator.
- FROM
- £0
- TIME
- No fixed timescale is published: the Charity Commission warns of high application volumes (allow several weeks), and OSCR states no processing time (unverified).
- LIABILITY
- Limited
- YOU NEED
- England and Wales: the legal minimum is 1 trustee, but GOV.UK says you usually need at least 3 and the Commission recommends 3 unrelated trustees. SCIO: at least 3 charity trustees and at least 2 members.
Is it right for you?
GOOD FOR
Charities with charitable purposes for public benefit that want limited liability without dual company and charity regulation.
NOT FOR
Groups that want to distribute profit, or charities in Northern Ireland, where CIOs did not appear to be available in the sources found (unverified).
Liability: Members may have no liability or only limited liability for the CIO's debts.
Minimum capital: None
Step by step
Check your purposes are charitable and for public benefit
Charitable purposes include relieving poverty, education, religion, health, the environment and animal welfare. You cannot set up a charity to help one specific person.
Recruit trustees
You usually need at least 3; the Charity Commission recommends at least three unrelated trustees with a range of skills. Trustees must be 16 or over and not disqualified.
Choose a name
The main and working names must not be the same as or too similar to an existing charity's, use words you lack permission for, or mislead. Check the charities register. Avoid a name that would need sensitive-word approval.
Choose Foundation or Association model
Foundation: only the trustees are voting members. Association: a wider voting membership. Use the Commission's model constitution to speed up registration.
Hold a trustees' meeting to sign the constitution
The trustees must meet to approve and sign the governing document before you apply.
Gather the application details
Bank or building society details, contact details with a postal address (usually not a PO box), each trustee's name, date of birth and contact details, and the constitution as a PDF. Proof of income is not needed for a CIO.
Apply with 'Apply to register a charity'
Apply online with the Charity Commission. You can save and return within 3 months. The Commission warns of high application volumes and publishes no fixed timescale.
The CIO exists once registered
A CIO comes into existence on registration and gets a registration number. It has a principal office in England or Wales and must keep registers of trustees (and members for an Association CIO).
Get HMRC charity recognition and open a bank account
To claim charity tax reliefs, apply to HMRC for recognition as a charity. Open a bank account in the CIO's name.
Scotland: set up a SCIO with OSCR
Apply on OSCR's online form (free). You need at least 3 charity trustees, each signing a trustee declaration form, and at least 2 members. The SCIO becomes a corporate body when entered in the Scottish Charity Register.
Northern Ireland: check with CCNI
Charities are registered by the Charity Commission for Northern Ireland, and registration is compulsory. CCNI says it has paused inviting applications while it moves to a new system; start with its Expression of intent form.
What you need
- Constitution (Foundation or Association CIO model), as a PDF
- Charity name and a statement of charitable purposes and how they are for public benefit
- Trustees' names, dates of birth and contact details
- Charity bank or building society details and a public postal address (usually not a PO box)
- SCIO: a trustee declaration form signed by each proposed trustee, a draft governing document, and the names of 2 or more founding members
- Proof of income is not needed for a CIO (it is for other charities with income of £5,000 or more)
