The Board of Trustees is ultimately responsible for strategic decisions of the charity, having regard to advice from the Chief Executive and the Executive Team. The Board has legal accountability to ensure our assets are used exclusively to further the objectives of the charity. The board meets quarterly.

Our trustees 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.  You can find out more about becoming a trustee here.
