Greystoke

What Greystoke does

Greystoke (trading name of Greystoke Land Limited) is a UK-based data centre masterplanner and developer headquartered in Oxford. The company's core competency is site selection, planning permission acquisition, power grid connection activation, and project delivery for large-scale hyperscale data centres serving cloud computing and AI training workloads. Its portfolio comprises three consented projects — Abbots Langley (96 MW cloud), West London Technology Park (90 MW cloud), and Humber Tech Park (384 MW AI training) — together representing nearly 600 MW of consented capacity and £5bn of associated inward investment. Beyond these, Greystoke has a 2.5 GW total pipeline backed by 2.5 GW of accepted grid connections, and is leading the proposed Northern Lincolnshire AI Growth Zone in partnership with North Lincolnshire Council, targeting up to 2.5 GW of additional AI compute capacity and £20bn+ of private investment.

Greystoke earns revenue through development fees, project delivery services, and the longer-term ownership or sale of data centre assets, structured on a project-by-project basis with enterprise technology companies, hyperscale cloud providers, AI companies, infrastructure investors, and government counterparties. Its go-to-market combines direct enterprise sales to technology and AI customers with a channel-partner model delivered through joint ventures with energy companies (Anglo Renewables, Anglo Energy Storage — 378 MW battery and 115 MW solar permitted) and with development partners (Greystoke CB, covering high-tech manufacturing and life sciences campuses, film studios, and logistics parks). Pricing is not publicly disclosed, reflecting the bespoke, multi-billion-pound nature of each infrastructure transaction.

The company is privately held, with no disclosed funding rounds, revenue, or headcount. Leadership identified in the source material is limited to a single C-suite officer (COO Sam Matthew). Operating geographies are restricted to England, with regulatory and stakeholder relationships concentrated through the NLAIGZ Partnership Forum that includes the Humber Energy Board, Humber Freeport, North Lincolnshire Council, CATCH, and the Federation of Small Businesses.

Product overview

Greystoke is a data centre master developer offering a portfolio of large-scale data centre projects across the UK, not a unified software platform. The core product portfolio comprises five distinct data centre projects: three consented hyperscale/cloud data centres (Abbots Langley at 96 MW, West London Technology Park at 90 MW, and Humber Tech Park at 384 MW for AI training) with combined computing power of approximately 570 MW; the proposed Northern Lincolnshire AI Growth Zone (NLAIGZ) aimed at delivering up to 2.5 GW across four AI campuses; and Elsham Tech Park as a £10bn AI campus. Greystoke operates two joint venture sub-brands—Anglo Renewables/Anglo Energy Storage for battery and solar projects, and Greystoke CB for high-tech manufacturing and life sciences campuses. The data centre projects are positioned in UK availability zones and serve cloud computing and AI training workloads.
