New CEO for Siemens UK & Ireland vows to ‘build on strong foundations’ at global giant

Brian Holliday has worked at Siemens for more than 32 years

Industrial and technology giant Siemens has named Brian Holliday as its CEO of its £4.6bn UK and Ireland business to “build on the strong foundations already in place”.

Manchester-based Mr Holliday has worked for Siemens for more than 32 years across a number of leadership and tech roles. He has been a member of the UK and Ireland senior leadership team for 10 years and will continue as managing director of Siemens Digital Industries.

Mr Holliday is a Fellow of the Royal Academy of Engineering and visiting Professor at the University of Sheffield, holding degrees from Cardiff University and the University of Manchester as well as an honorary doctorate from Middlesex University.

He is co-chair of the Made Smarter Commission, which works with SMEs to improve manufacturing productivity, and was recently appointed to the board of Skills England to advocate for SMEs and social mobility. He started his career as an apprentice with Texas Instruments and continues to focus on applied learning and vocational training.

Siemens’ UK & Ireland business employs 12,000 people and generated £4.6bn in revenue in 2025.

Matthias Rebellius, managing board member of Siemens AG, responsible for UK and Ireland, said: “Brian brings a deep understanding of our strategic priorities and our customers, as well as strong insight into the challenges facing industry as it digitalises. His external experience with the Catapults and Made Smarter will also be a real asset.

“Brian will build on the strong foundations already in place, continuing to drive focus on the areas where we can make the greatest difference and create more value for customers. This will be even more important as we take forward our ONE Tech Company programme and ensure we serve our customers in a seamless, straightforward way.”

Mr Holliday said: “I’m honoured to take up this position at a time of significant change, where technology and talent can make a real difference. I’ve always been proud of our people and struck by the commitment and sense of purpose evident across our UK and Ireland organisation – thus I’m genuinely excited to lead this strong team. With global leadership in industrial technology and AI, as well as the partnerships we’ve developed, Siemens is well set to help our customers with their competitiveness, resilience and sustainability.”
