Ark Data Centres is a UK-founded colocation and wholesale data centre operator that designs, builds and runs its own purpose-built campuses rather than reselling third-party space. As of 2025-2026 the company operates active campuses at Cody Park (Farnborough), Spring Park (Corsham) and Meridian Park (north London), with further campuses — Union Park and Alliance Park in west London, and Longcross Park in Surrey — in various stages of build-out, plus a Brussels facility giving it a small international footprint. Founded in 2005 and majority-owned by Elliott Investment Management since 2012, Ark counts hyperscalers, the UK government (via its Crown Hosting joint venture with the Cabinet Office) and large enterprises among its tenants. In 2025 the company signed AI infrastructure specialist Nebius to deploy 4,000 Nvidia Blackwell Ultra GPUs at its Longcross Park campus, part of a announced £7.5bn UK expansion push, and it is separately pursuing a planned 200MW campus on a former hotel site near Elstree that it says could become London’s largest data centre site once built.
Ark Data Centres operates as a cloud provider and colocation provider, with facilities at the following locations:
