Ark Data Centres is a UK-headquartered colocation developer and operator that builds and runs large wholesale data centre campuses across the UK and Belgium, serving hyperscale cloud providers, government bodies (via its Crown Hosting joint venture with the UK Cabinet Office) and large enterprises. As of 2025-2026 the company operates around 27 data centre buildings across roughly nine campus locations, with more than 560MW of capacity, and has become notable in the AI infrastructure world for hosting Nebius’s first UK Nvidia Blackwell Ultra GPU cluster at its Longcross Park campus in Surrey, part of a announced £7.5 billion UK expansion plan. Founded in 2005 (with its flagship Spring Park campus in Corsham going live around 2010), Ark differentiates itself through modular, off-site-constructed buildings, low-PUE indirect/direct air and liquid cooling, and high-security siting choices such as its Corsham campus’s proximity to the Ministry of Defence’s Corsham site. Ark is backed by Elliott Investment Management, with Revcap as a minority investor, and has been expanding rapidly to meet demand from AI cloud tenants and hyperscalers.

Does Ark Data Centres have facilities specifically built for AI/GPU workloads?

Ark's Longcross Park campus in Chertsey, Surrey hosts a Nvidia Blackwell Ultra GPU deployment for AI cloud provider Nebius, announced in June 2025 and launched with an initial 4,000 GPUs by November 2025, with plans to expand capacity and add a further 36MW building (LP02) as part of an £807 million investment in the site.
How many data centre locations does Ark Data Centres operate?

Is Ark Data Centres a cloud provider or a colocation company?
Ark is a colocation provider - it sells wholesale and enterprise colocation space to hyperscalers, enterprises and government tenants, and connects customers to cloud providers via on-site cross-connects, rather than selling its own cloud compute service directly.
Where is Ark Data Centres headquartered?
Ark Data Centres is headquartered at Spring Park, Westwells Road, Hawthorn, Corsham, Wiltshire, UK, which is also the site of its original and longest-running data centre campus.
