The Board of Trustees is ultimately responsible for the strategic decisions made by the charity. The board works closely with the Chief Executive and the Executive Team and has legal accountability for the charity and a responsibility to ensure our assets are used exclusively to further the objectives of the charity.

Our trustees meet quarterly and receive no remuneration for their services, nor do they have any business or personal interest in the charity’s contracts. Trustees normally serve for a maximum of six years and are subject to re-election after three years.
