Meet the board

Our board of directors play a key role in the running of Wessex Water Services Ltd.

The purpose behind the board

Our board of directors has responsibility for providing leadership, setting strategy, reviewing management performance, ensuring we have the financial and human resources needed to achieve our objectives, and ensuring that the company meets its obligations to stakeholders and shareholders.

Our board members

Our board is made up of executive directors and non-executive directors. The executive directors have day-to-day management and operational responsibilities whereas the non-executive directors do not.

As well as shareholder non-executive directors, five independent non-executive directors are appointed from diverse backgrounds, each bringing a range and depth of experience to the board. The independent non-executive directors provide challenge and perspective and are essential to securing strong board leadership and governance.
