ISG secures contract to build secondary 30MW data centre in Slough

ISG, the global construction specialist, has secured the contract to construct a secondary 30MW data centre in Slough. This marks the subsequent phase of work for one of the UK's largest data centre hubs, following the initial phase which is due to complete in early 2024. The client, Yondr, will benefit from the construction of this second data centre, enhancing its capacity within the hub.

The construction of this state-of-the-art data centre is a valuable project within the local economy. As one of the largest construction projects currently underway in Slough, ISG's works encompass not only the main data centre building, but the delivery of ancillary buildings and structures.

Included are the main entrance gatehouse, external plant compounds, a site-wide substation, mechanical yard, and associated infrastructure.

Ahead of the second phase, ISG is already on site at the new 100MW data centre campus development, completing the first of three planned multi-storey data centre buildings. The second phase outlined includes an identical three-storey 30MW data centre building at the campus. Full handover of this second data centre to Yondr is expected in 2025.

This new phase of construction represents a commitment to innovation, meeting the rising demand for shared applications and data.

Daniel Priest, ISG's director for data centres, stated: "The latest advancements in AI have further added to the exponential demand for shared applications and data, which is driving a race for space within this critical national infrastructure sector."

Priest highlighted the company's prowess in this sector, commenting, "Our ability to deliver highly technical space at pace, and with a critical focus on quality and innovation, are important factors driving repeat relationships in this sector, creating significant value and opportunity across our supply chain and within communities and the regional economy."

This announcement follows several wins for the company, including leading the refurbishment and redevelopment of London's Regent Quarter near King's Cross into a life sciences-led campus, a job estimated to be worth around £70m. This first phase is due to complete in Q4 2025 paving the way for future works to start on the seven-phase, 10-year masterplan for the estate.

Jason Curtis, managing director for ISG said: "This important milestone is the culmination of extensive collaboration over the past 12 months, and we are excited to get started on the construction phase and deliver this transformational project for King's Cross."

"This scheme represents one of the UK's largest life science conversion projects and creates significant opportunity to deliver wider social value benefits as we work with local stakeholders and Islington Council to maximise this investment potential."
