TROON-based quarrying and construction materials specialist Hillhouse Group has appointed Alistair Borthwick as the firm’s new CEO.
He is succeeding Robert McNaughton, who retires in April following almost two decades in senior leadership roles within the business.
Borthwick joins from NATS, where he served as chief financial officer. The move marks the start of a structured transition period lasting until April. Hillhouse explained that the transition plan is designed to maintain stability, reassure customers and partners, and support the organisation’s long-term strategic goals.
Under Robert McNaughton’s leadership, Hillhouse has grown from an Ayrshire-based business into one of the largest privately owned companies in Scotland. He has overseen major strategic and operational change.
Hillhouse supplies aggregates, asphalt, ready-mix concrete and civil engineering services across Scotland’s central belt.
Elsewhere in the business, Mark Munro has been promoted to MD of Hillhouse Quarry Group. He has more than 25 years of experience across the group, most recently as commercial director.
Andrew Vernon, chairman of Hillhouse Group, said, “Robert’s contribution to Hillhouse over the past 18 years cannot be overstated. He has been instrumental in transforming the organisation and has championed a strong culture focused on people, innovation and operational excellence.
“As we look to the future, the appointments of Alistair and Mark reflect both our commitment to continuity and our ambitions for the next chapter. Alistair brings strategic and financial leadership and a forward-looking perspective, while Mark’s deep operational experience will ensure stability for our people and our customers. Together, they are exceptionally well positioned to lead Hillhouse Group into the future.”
Incoming CEO Alistair Borthwick commented, “I’m pleased to be joining Hillhouse Group at such an important period in its long and proud history. The business has built an exceptional reputation for quality and service, and I’m looking forward to working with the team to build on that strong foundation in the months and years ahead.”
