How many trustees does a charity need?

Follow your governing document's rules on numbers. The Commission recommends at least three trustees, unconnected and unrelated, with a good range of skills.

The age is the legal minimum: 16 for a CIO or charitable company, unless its governing document says older; 18 for any other charity.

Can a charity have one or two trustees?

Why three

The model notes give two reasons: better decisions, and sharing the duties and responsibilities. A trustee who can't vote on a matter because of a conflict doesn't count towards the quorum for it. With three trustees and a quorum of two, if one must step out, the other two can still decide. Any payment to a trustee also has to be legally authorised.

Related trustees

The Commission recommends trustees who are unconnected and unrelated. If a couple and their child are the trustees, a proposed payment to one of them could leave all three conflicted, with no one left to decide. For trustee payments for goods and services, section 188 of the Charities Act 2011 defines connected persons: specified relatives, spouses and civil partners, business partners, and organisations they control or have a substantial interest in.

Upper limits

The CIO guidance suggests 12 as a maximum, so everyone can take part in meetings, but allows a higher or lower number. The CIO models let you choose a fixed number or a range.

If numbers fall below the minimum

Under the CIO models, the remaining trustees can only call a trustee meeting or appoint new trustees until numbers are back up. Under the model trust deed, if numbers fall below the quorum, the remaining trustees can only appoint new trustees. Follow your own document.
