Our Trustees

Our Trustees work to a robust governance framework which ensures that Quarriers is being managed in the best interests of its stakeholders.

Quarriers’ Board of Trustees

Quarriers’ Board of Trustees is made up of the Chairperson and thirteen Trustees. All of our Trustees, including the Chairperson, are volunteers.

Every second month a Board meeting is held where our Board of Trustees meet with the Chief Executive Officer and the Executive Directors to discuss the management and performance of the organisation.

Our Trustees work to a robust governance framework which ensures that Quarriers is being managed in the best interests of its stakeholders, this is achieved by the Board of Trustees having ultimate responsibility for:

  • The direction, control, financial management of the organisation, compliance with all our legal, regulatory and reporting obligations which govern our activities.

  • Ensuring there is a balance of skills and experience within the Board of Trustees.
