Ark Data Centres is a UK-founded wholesale colocation developer and operator that builds and runs purpose-built data centre campuses for hyperscalers, cloud providers, governments and large enterprises, rather than selling remote cloud services of its own. As of 2026 the company describes itself as operating 27 data centres across 9 strategic UK and Belgian locations, with more than 560MW of capacity in operation or development, and it has become one of the country’s fastest-growing wholesale operators on the back of surging AI/GPU demand. Its flagship AI deal is a long-term agreement with Nebius, which has deployed NVIDIA HGX B300 and Blackwell Ultra GPU clusters at Ark’s Longcross Park campus in Surrey, backed by an £807 million ($1bn) expansion commitment announced in 2026. Ark’s core campuses include Spring Park (Corsham, Wiltshire), Cody Park (Farnborough), Meridian Park (Enfield, north London), Union Park (Hayes, west London), Alliance Park (Park Royal, west London) and Longcross Park (Chertsey, Surrey), alongside newer sites in development at Elstree (a planned 200MW, £2bn campus on a former hotel site) and a Brussels campus in Belgium. Founded in 2005, Ark also runs the Crown Hosting Data Centres joint venture with the UK Cabinet Office, channelling public-sector demand into its facilities.
Its buildings are known for modular, off-site steel construction, low PUE targets, and a heavy emphasis on renewable power, direct/indirect air cooling and, increasingly, liquid cooling for high-density AI racks.

AI Data Centers
Ark's most AI-focused site is Longcross Park in Chertsey, Surrey, where AI cloud provider Nebius has scaled up to full-building occupancy running NVIDIA HGX B300 GPUs and, from 2026, one of the UK's first Blackwell Ultra GPU deployments in a purpose-built, liquid-ready data hall. Ark backed the expansion with an £807 million ($1bn) investment commitment, adding a new 36MW building (LP02) and vertical extensions to existing structures to support high-density, liquid-cooled AI compute. Other campuses such as Cody Park, Union Park and Meridian Park are also marketed by Ark as "AI-ready," though the clearest, customer-confirmed AI/GPU deployment to date is the Nebius cluster at Longcross.
