About Deep Green

Deep Green designs, builds and operates decentralised and decarbonised data centres, recapturing and reusing the heat they generate for the benefit of everyone. We were established in 2021, famously providing heat into a swimming pool in Exmouth. Fast forward to 2025, and we are now providing heat into homes, public spaces, and industry through District heating Systems, always leading on the positive economic, environmental and societal impact of what we do. From humble beginnings, and a 50kW data centre, we’re now deploying 300MW across UK&I and potentially North America and Europe. We are backed by Octopus Energy generation, the renewable energy investment and asset management arm of Octopus Energy Group, one of the UK's largest energy suppliers.

We are a double-sided business. On the one hand we sell compute hosting to meet the demands of clients, notably with high performance, high density capacity requirements, and on the other, a public private partnership with heat host sites, where each site is a unique SPV.
