Colt DCS is set to double the size of its planned data center campus in Hayes, West London, after acquiring a fresh parcel of land.
The company, which provides hyperscale and large enterprise data center solutions, says the expansion will make the campus the largest in its global portfolio.
Based on the site of the former Optimum Data Centre facility on the Springfield Road Industrial Area, Hayes, the initial phase of the campus is currently under construction and will comprise two buildings with 60MW IT capacity. Building work began last year, and it is expected to come online in Q3 2025.
Colt DCS has now secured a second piece of land adjacent to its current plot, which the company says will allow it to more than double the size of the campus. Specifications of the second stage of the development, and timescales for construction, have not been shared.
A Colt DCS statement said: “This will make the entire site one of the largest in the UK and will be Colt DCS' largest multi-building data centre campus across its global estate.
“Along with the purchase of land, Colt DCS has crucially also secured power, based on renewable energy, to deliver the capacity required for the new site. Colt DCS' expanded campus will be perfectly suited to support the growing demand for capacity of large-scale, high-density AI workloads.”
Richard Wellbrock, chief commercial officer at Colt DCS, said: "There is continued strong demand from customers for UK-based hyperscale data centres, driven by continued growth in demand for digital services.
“To cater for the fast-paced world of digital services, customers require scale in their data centre solutions. We are also excited to learn about the UK Government's plans to take the digital economy to the next level in the global marketplace, and our expansion in Hayes will increase the UK's capacity and capability in creating a vibrant environment for growth.”
