Rachel Reeves' Mansion House speech placed sovereign AI capability at the centre of the government's economic strategy. The cloud infrastructure sector's response is that the energy policy will need to catch up.
The tension sits in a straightforward exclusion: data centres fall outside the British Industrial Competitiveness Scheme. The scheme is designed to offset high energy costs for energy-intensive industries, but digital infrastructure — which provides the compute capacity underpinning AI, cloud services and the wider digital economy — does not qualify for relief under it.
That exclusion matters because AI infrastructure is economically mobile. Hyperscalers running large-scale compute can route capacity to jurisdictions where electricity is cheaper while continuing to serve UK customers. UK data centre operators, particularly the independent providers committed to British infrastructure, have no equivalent flexibility. High UK power prices therefore risk pushing AI compute offshore.
Jake Madders, Director and Co-founder of Hyve Managed Hosting, argues that investment announcements and domestic capacity commitments will not by themselves deliver sovereignty: "The real test is who owns and controls the infrastructure, which jurisdiction applies, where operational decisions are made and whether customers can move workloads without being locked into a single provider."
Without greater alignment between AI ambition and energy cost relief, independent providers face sustained pressure that could force more AI computing outside UK control — taking ownership and operational decision-making with it. Madders identifies extending energy cost relief to digital infrastructure as a necessary first step: the scheme that is intended to support energy-intensive industries is, at present, actively disadvantaging the sector the government needs to keep onshore.
