Atos selected by SSE to deliver 5-year Digital Workplace, Cloud and SIAM services

London, UK – November 9, 2026 – Atos, a global leader in AI-powered digital transformation, today announces a five-year contract with SSE to deliver its SIAM services, digital workplace, cloud operations and data management platforms.
 

Atos brings decades of mission critical engineering experience across critical national infrastructure (CNI) such as energy, rail, water and aerospace environments where reliability, resilience and security are at the core of all services. 
 

At the heart of the contract, Atos will provide SIAM services with the aim of strengthening, simplifying and elevating SSE’s IT landscape. As the first company to achieve dual Scopism SIAM Assured status, Atos will use its best practice blueprint, define a long-term Partnership Charter unique to SSE’s team and values, and build a data-driven approach to service excellence and innovation. 
 

Atos will also manage Service Desk and End User Services for SSE’s over 14,000 team, moving towards a proactive monitoring service that addresses issues before they have an impact on employees. Atos will support SSE’s environmental goals by improving device longevity through proactive maintenance, performance-based refreshes and the incorporation of remanufactured devices.
 

As SSE embarks on its £33bn five-year investment programme to transform the UK’s electricity infrastructure and deliver long-term benefits for society, Atos will provide foundational services to allow for the management of an expanding portfolio and mandate.
 

Michael Herron, Head of Atos UK&I said, “We’re delighted to partner with SSE to support its goal of delivering a cheaper, cleaner, more secure energy system. We understand that the service SSE provides is critical and resilience is essential and will work to strengthen its infrastructure, support the people who keep it running and protect essential services with mission‑critical experience, sovereign security and next‑generation technology.” 
 

Stewart Fry, SSE Group Chief Information Officer said, “We needed a partner who understood the complex needs of a business like ours, delivering vital always-on services to our customers. As we focus on our programme to transform the UK’s electricity infrastructure and deliver long-term benefits for society, we need foundational digital services we can rely on, that are intelligent, secure and future-ready.”

Atos’ newly launched Centre of Excellence for CNI will be available to SSE for future innovation needs, providing access to insights and knowledge about relevant technologies and innovations. The Centre is designed to tackle complex industry challenges through collaboration and knowledge sharing across the sector and its regulators.
