Arup has announced a new board structure that sees current group chair Jerome Frost step into a newly-created CEO role from April 2025.

Hilde Tonne, former CEO of Norway’s transmission system operator Statnett SF, will join as non-executive chair of the firm’s new Arup Group Limited Board.

She brings a wealth of experience, having previously served as executive director at Telenor Group and chief innovation officer at Ramboll.

Since its trust-owned structure was first established in the late 1970s, Arup has grown into a global consultancy with 18,000 staff working in over 140 countries.

The new management structure from April will be:

Arup Group Limited Board: appointed by the trustees and led by Hilde Tonne as non-executive chair. The board’s role will be to provide oversight of strategy execution, the firm’s performance, compliance, and leadership appointments.

Executive Management Board: led by Jerome Frost as CEO. The board will be responsible for Arup’s leadership, operations and implementing the strategy.

Arup Trustees: Mahadev Raman will continue as Chair of Trustees, maintaining the trustees’ role of safeguarding the firm’s independence, long-term success, and unique culture on behalf of Arup’s members.

Further appointments to the new boards will be announced next year.
