The steps that are required to implement a new fee structure will depend upon whether the existing fee structure is specified in the CIO’s constitution. The Charity Commission has given two alternative forms of constitution for CIOs; a foundation constitution, designed for CIOs with charity trustees who are the only voting members, and an association constitution , designed for those CIOs with a wider membership and voting powers. A CIO’s constitution must be in one of these forms specified by Commission regulations, or as near to that form as the circumstances allow. For the purposes of this Q&A, it has been assumed that the CIO has an association constitution. If it mirrors the model association constitution closely, this means it will give a general discretion for the charity to set and charge membership fees as it sees fit,
