The UK has 1 confirmed Green Mountain facility, in Romford, marking the company’s first expansion outside Norway when it acquired the site (then operated by Infinity SDC) in 2022. The facility sits in East London, an area the company has publicly framed as an emerging alternative to the traditionally dominant west London data center corridor as space and power there tighten. In June 2026 Green Mountain acquired the freehold of the Romford campus outright, giving it long-term control to develop the site’s remaining capacity for AI, hyperscale, and enterprise demand.

Green Mountain AI Data Centers in UK
The Romford campus, known internally as LON-East, is being built out specifically for high-density AI and HPC workloads: 7 MW has been operational since 2010, with roughly 14 MW more delivered recently and a total planned capacity of 37 MW. It sits equidistant between the LSE data centre in Docklands and the NYSE data centre in Basildon, with sub-millisecond fiber latency to the City, Docklands, and Slough. In 2025 Green Mountain signed an unnamed neocloud operator to 14 MW of capacity there, and the expanded halls are being engineered with liquid-to-liquid and direct liquid cooling pre-integrated alongside standard air cooling for future AI chip densities.

A human decides whether each page is published, but individual facts — addresses, contact details, and whether a company operates in a given location — are not independently fact-checked by us. Where you see a “Verified” badge, it means multiple independent sources agreed, not that we personally confirmed it. Companies open, close, relocate, and change contact details without always updating public records, so treat everything here as a starting point, not a confirmed source.
