CyrusOne has announced plans to build a major new data center campus, LON6, in Iver Heath, Buckinghamshire. The 90-megawatt facility will be the company’s sixth UK location and represents a key expansion in its European growth strategy. Slated to break ground in Q3 2026, with initial power arriving in mid-2027 and service beginning in early 2028, LON6 will span 30,000 square meters across six data halls.
The £1.2 billion project places sustainability and biodiversity at the heart of its design, targeting a 71% Biodiversity Net Gain—significantly above the 10% UK legal requirement. Green roofs, planted walls, a biodiverse lake, and nearly 73,000 square meters of public green space are key features. The facility will be powered entirely by certified renewable electricity and will include on-site solar panels to meet 64% of its office energy needs. Additional sustainability measures include rainwater reuse, free air cooling, and EV charging infrastructure.
LON6 is also expected to provide significant economic benefits to the region, including 580 construction jobs and 540 long-term skilled positions. A dedicated training center located on campus will support education and apprenticeships, extending CyrusOne’s partnership with UTC Heathrow. “As demand for digital services continues to accelerate, larger facilities are necessary to provide the economies of scale that customers need,” said Matt Pullen, EVP and Managing Director, Europe, CyrusOne.
