April 23, 2026 – 8:47 am
Nscale will construct the data centres at existing BT infrastructure sites; BT will provide connectivity. Both companies are founding members of the new UK Sovereign AI Industry Forum. The deal deepens Nscale’s position as a central plank of the UK government’s national AI infrastructure strategy.
Key Points:
- Partnership Details: BT Group and Nscale are collaborating to deliver sovereign AI data centres in the UK using Nvidia’s full-stack AI infrastructure.
- Capacity: Nscale will build up to 14 megawatts of AI data centre capacity across three existing strategic BT sites in the UK.
- Infrastructure: BT will provide the underlying infrastructure and connectivity for these sites, leveraging its ownership of the UK’s fixed telecommunications network through Openreach.
- Strategic Advantage: The partnership allows Nscale to co-locate AI data centres with BT network exchange and switching sites, achieving low latency and avoiding greenfield build costs.
- Monetization: For BT, this partnership offers a new commercial AI revenue stream from existing infrastructure repurposed for AI compute.
