Graham Prothero will step down from the board of building product firm Marshalls at the company’s 2026 annual general meeting after nine years as a non-executive director.
Chartered accountant Prothero, chief executive of housebuilder MJ Gleeson , currently serves as Marshalls’ senior independent director and chairs its audit committee.
He will be succeeded in both Marshalls roles by Paul Inman, who has been appointed to the board as a non-executive director and audit chair designate from 15 September 2025.
Inman most recently served as chief financial officer at Yorkshire Water and previously held senior roles at BAE Systems and Rolls-Royce. He will also join the remuneration, nomination and ESG committees.
Diana Houghton, who joined Marshalls’ board in 2023, will replace Prothero as senior independent director following his departure.
Chair Vanda Murray said the appointments formed part of a wider succession strategy, and praised Prothero’s contribution in steering the board through governance changes and business challenges during his tenure.
Inman’s appointment followed a formal process led by the nomination committee with support from executive search firm Russell Reynolds Associates.
Prothero’s previous roles include chief operating officer of Vistry Group, chief executive of Galliford Try, and senior positions at Development Securities (now Land Securities), Taylor Woodrow and Blue Circle Industries.
Earlier in his career, he spent seven years as a partner in Ernst & Young’s real estate, hospitality and construction group.
