The Board meets regularly (at least six times a year).

Currently, the Milford Haven Port Authority Act 2002 provides for a board consisting of a non-executive Chair, up to nine other non-executive members and up to three executive members (currently the Chief Executive, Chief Financial Officer, and Harbourmaster). The Chair is appointed by the Secretary of State and all other non-executive appointments are made by the Port, three of which are made in close consultation with Pembrokeshire County Council.

Non-executive members in all categories are sought so as to provide a mix of experience and expertise in areas including, but not exclusive to, port management, shipping, navigation, environmental conservation, finance, commerce, local government and organised labour.


A Trust Port is a valuable asset presently safeguarded by the existing board whose duty it is to hand it on in the same or better condition to succeeding generations.

This is the ultimate responsibility of the Board, and future generations are the ultimate stakeholder.
