UK-based leader in energy data, metering and infrastructure, Stark, has signed an agreement to acquire the UK Energy Services business from Siemens today.
Bringing together these highly skilled and complementary organisations which have a strong reputation for innovation and technical expertise with a customer-focused approach, is set to expand offerings and strengthen their UK energy sector presence.
Siemens is a leading technology company focused on industry, infrastructure, mobility, and healthcare – and this acquisition reinforces Stark’s commitments, which involve long-term growth, focus on innovation, and making the right investments to create stronger offerings in the UK’s energy services market.
CEO of Stark, Alex Warren, made comment: “This acquisition brings together Siemens unrivalled engineering experience and Stark’s ingenuity with data services to steer the UK’s energy transition and enable our customers to be perfectly positioned to manage it. We value what the Energy Services business has created, and we hold similar values.
“Our mission at Stark is to empower customers with best-in-class data, metering, and infrastructure. This opportunity enhances our ability to do just that. Our combined strength and valued customer base will allow businesses to successfully manage their energy costs and reduce carbon impact.”
This partnership will allow Stark to expand – with greater engineering capabilities and double the team to more than 250 engineers. Building on Stark’s existing activity in infrastructure landscape will be critical, to keep up with the demands of Market-wide Half Hourly Settlement (MHHS).
Head of Siemens UK Energy Services (EYS) business, Hani Ratib, said: “Stark is a well-established and renowned player in the UK energy data, metering, and infrastructure sector. They bring a deep understanding of local market dynamics and have a proven track record of successful business development. Their industry expertise and market presence make them an ideal partner to support the future growth and development of the Energy Services business.”
This acquisition will also be central to the next phase of the UK energy transition – creating opportunities for more complex, high accuracy metering solutions and increasing the capabilities of Stark’s existing Independent Connection Provider (ICP) and Independent Distribution Network Operator (IDNO) services.
This deal will see Stark enter the domestic market – serving millions of homes – to optimise energy transition for suppliers and customers, in assuming responsibility to operate the country’s gas prepayment infrastructure.
Worth note, is that during this transition period there will be no disruptions to current services and each business will continue to operate as separate entities.
CEO of Siemens UK and Ireland, Carl Ennis, commented: “The sale is part of Siemens portfolio strategy to divest from non-core businesses: The Energy Services business will gain new opportunities for growth under new leadership. At the same time, it will allow Siemens to concentrate more intensively on its core business activities, enabling Siemens to better leverage its key competencies and market position.”
After the expected legal transfer in early 2026, Energy Services business will become a standalone unit within Stark’s UK-based group structure. Both companies are committed to making this a smooth and transparent integration, so all Siemens employees will be retained. This will foster alignment and knowledge sharing across relevant teams.
The combining of these teams will benefit customers upon completion. They will see highly experienced organisations offering broader capabilities, deeper technical knowledge and enhanced responsiveness across the energy services lifecycle.
