Nebius, Nvidia to invest £1.7bn for 65MW UK AI capacity

Nebius and Nvidia will invest £1.7 billion to deploy 65 megawatts of Nvidia AI infrastructure across three sites in the UK, the companies announced. One of the contracts is a 10-year, 22MW deal with data centre developer Kao Data at its Harlow campus that will run on 100% renewable energy with hydrotreated vegetable oil (HVO) generators as backup.

The capacity will use Nvidia’s latest full‑stack AI factory platform and is expected to reach 65MW when fully ramped up next year. Nebius said the deployments form part of its plan to expand a commercial and AI research and development hub in London.

Nebius plans to allocate the new capacity to inference workloads. The company said that pairing inference capacity with local infrastructure will let UK businesses and research teams train, test and run advanced models close to their data and customers.

Andrey Korolenko, Nebius’s chief product and infrastructure officer, said the UK is an important part of the company’s global footprint and that the dedicated capacity will support enterprises pursuing AI work on local systems.

Nvidia highlighted the agreement alongside several other ecosystem investments in the UK. Paolo Guglielmini, Nvidia’s vice president for EMEA, noted that the expanded access to Nvidia infrastructure aims to give British firms the performance and economics to train and deploy frontier and open‑source models.

Other projects in the Nvidia ecosystem include CoreWeave building in designated AI Growth Zones and work by BT and Nscale to create sovereign AI data centres across three BT sites using Nvidia infrastructure. Cosine is developing a sovereign AI coding platform on the Isambard‑AI supercomputer built with 5,400 Nvidia GH200 Grace Hopper Superchips. Doubleword is operating an inference lab that runs open models such as Nvidia Nemotron 3 Super 120B on the Nvidia Dynamo inference framework. Prima Mente is building biological foundation models to identify biomarkers and drug targets for Alzheimer’s, Parkinson’s and ALS. Cursive is developing self‑improving AI systems, with some funding from the Sovereign AI Fund.

UK AI minister Kanishka Narayan welcomed the investment, saying it brings substantial AI compute to the country and will support wider AI deployment across the economy. Talfan Evans, cofounder and CEO of Cursive, described the Sovereign AI Fund as a targeted investment in UK AI and said that buying decisions increasingly consider where compute and data are hosted.

The agreements add to government and industry efforts to expand domestic AI capacity and to give regulated organisations on‑shore options for sensitive workloads. Nebius’s London expansion and the Harlow deployment aim to provide local compute and supporting services for British businesses, researchers and public services to develop and run advanced AI systems.
