For immediate release 3 August 2020

Following Ofwat’s approval of the code change (CPM026) allowing for the MOSL Board and Panel Chair to be two people, MOSL has today announced Anne Heal, current Independent Non-Executive Director of the MOSL Board, as its new Chair.

A dedicated Panel Nominations Committee, led by independent Panel member, Elsa Wye, has also today announced its appointment of Trisha McAuley OBE as its new Chair.

The two milestone appointments not only mark a first for a new means of governance for MOSL – making a distinction between the two formally combined roles, but they also follow a number of recent appointments that put women in utilities in top leadership roles. McAuley and Heal join Sarah McMath, who was appointed MOSL CEO in June last year, in the next phase of the market, having opened just over three years ago, and as MOSL launches its new purpose, vision and strategy for its next three years, 2021-24.

Anne Heal had an active role in the development of MOSL’s strategy, as part of a Board sub-group and has been a director of the Board since January 2020. Jim Keohane, who is stepping down as MOSL Chair at the end of his tenure in August, and who has led the company through a number of significant changes during his three-year term, said of Heal’s appointment: “I am delighted to welcome Anne as the new Chair of the MOSL Board. Her experience and contribution in the short time she has been with us has been invaluable. Not only will her experience of being a director of the MOSL Board put her in good stead, but her extensive expertise in leading strategic change will be of great value at this critical time for the market.”

Anne Heal will formally take up her appointment on 1 September 2020.

In welcoming McAuley as its new Panel Chair, Elsa Wye, who headed up the Panel Nominations Committee said: “I am delighted that the Panel has endorsed the appointment of Trisha McAuley as the new Panel Chair. Trisha brings a wealth of experience from the energy and transport sectors and has a strong background in consumer advocacy. We are looking forward to welcoming Trisha, who will be an invaluable asset as the Panel moves forward with its first fully independent Chair.”

Trisha is an experienced Chair and Non-Executive Director, with experience in the public, private and voluntary sectors. For over twenty years she was a senior executive in UK and Scottish consumer organisations. She is widely recognised as a national consumer expert and was awarded an OBE for services to consumer affairs in 2015. Since then, Trisha has developed a successful non-executive and board portfolio, with a particular focus on regulated industries. 

Trisha McAuley OBE will formally take up her appointment on 1 September 2020.

In making the appointments and as MOSL continues to work closely with the industry Panel to deliver against its 2021-24 strategy, MOSL CEO, Sarah McMath, said: “This change is one of a number of changes we are looking to make to strengthen and modernise our governance at this critical time for the market. We have learnt a great deal over the last three years and it’s important that we, as the market operator, as well as the market itself, continue to evolve for the benefit of customers. I am delighted to have such strong Chairs in place to help lead us in the next stage of this journey, as we begin to deliver our ambitious plans for the next three years.”
