Andy’s appointment marks a new chapter for TIS as the company enters a phase of strategic growth
TIS Group has appointed Andy Walls as its new Chief Executive Officer, succeeding former CEO James Twigg, who will remain an active advisor and board member during the transition. Under James’ leadership TIS has evolved into a high-performing, innovative business trusted by organisations across retirement living, health and social care, education, public sector, hospitality, transport and the Ministry of Defence.
Andy’s appointment marks a new chapter for TIS as the company enters a phase of strategic growth and operational excellence. He joins TIS with a distinguished track record of leading complex service organisations, most recently serving as CEO of Marlowe Environmental Services. He brings deep expertise in delivering scalable growth, building high-performing teams, and enhancing customer value in regulated environments.
“TIS protects the people, places and spaces of some of the UK’s best-known businesses, organisations and institutions, including the Ministry of Defence, University of Leeds, Audley Villages, Notts County Council, Dnata, and West Midlands Combined Authority,” said Andy. “The business has a strong foundation, a talented team, and a reputation for delivering smart, customer-centric solutions. My focus will be on building on this success – accelerating growth whilst continuing to partner with customers, providing innovative, sustainable solutions and delivering service excellence. I look forward to getting to know the business, the people, and our partners over the coming months.”
Andy succeeds James Twigg, who has led the Group since 2013. James will remain on the Board as a Non-Executive Director, supporting strategic development and governance.
“Andy is a values-led leader with a proven ability to scale businesses while keeping people and customers at the heart,” said James. “The time is right for new leadership to take the business forward, and I’m excited to support Andy and the Board in the next chapter of the TIS journey.”
Underpinning the leadership transition is a clear and ambitious strategy for 2026 and beyond. With a growing customer base in sectors such as retirement living, defence, housing, education, and transport, TIS is well-positioned to scale its operations and extend its impact.
Guy Other, Chairman of TIS Group, commented: “Andy’s appointment signals our intent to build on TIS’s success with renewed momentum and clarity. His commercial acumen, operational discipline and people-first approach make him the right leader to take TIS into its next era. We are grateful to James for his outstanding leadership and are pleased he will remain part of the Group’s future.”
The transition is already underway, with Andy and James working closely to ensure continuity and alignment across teams, customers, and partners.
