Digital Reef Havering 600MW AI Tech Campus London
Status: Under Construction | Location: 499-Acre Fen Lane & North Ockendon Site, Havering Green Belt Corridor, East London
Project Overview
The Digital Reef Havering AI Tech Campus represents a ground-breaking development in the United Kingdom's digital landscape, establishing a massive 600-megawatt hyper-density computing footprint in East London. Spanning an expansive site designed to support massive artificial intelligence (AI) clusters, large language model (LLM) training engines, and cloud workloads, this project is one of the largest single-site data infrastructure investments in Europe. The facility addresses the critical shortage of power-secured, high-capacity technical spaces within the traditional London cloud corridor, positioning the UK as a primary destination for advanced supercomputing and sovereign data operations. A key highlight of the development is its unique integration with local environmental preservation efforts. Digital Reef is developing a massive public ecology park alongside the facility, establishing a blueprint for how heavy-density technology infrastructure can coexist responsibly with green belts and urban communities. Phase 1 of the multi-facility campus targets an initial 200MW baseline deployment, scheduled to go live by late 2026. This fast-tracked delivery timeline is bolstered by the UK government's late-2025 decision to classify data centers as "Critical National Infrastructure" (CNI), reducing bureaucratic delays and smoothing the permitting process.
