BT launches UK's first sovereign cloud & AI portfolio
BT has launched a sovereign services portfolio for UK public and private sector organisations, which it says is the first in the country to combine connectivity, voice, cloud and AI in a single sovereign offering.
The launch coincides with research from Assembly Research estimating that wider use of digital sovereignty could unlock £18 billion in productivity gains for the UK economy by giving organisations more confidence to adopt AI.
The portfolio is designed for organisations that need to keep sensitive and regulated workloads in the UK. It includes sovereign connectivity and voice services, a new Sovereign Cloud platform, and sovereign AI services built with Nscale and NVIDIA.
Assembly Research found that concerns over data security and control are slowing AI adoption across British organisations. It also pointed to a broader economic opportunity from domestic digital infrastructure, estimating that faster investment in UK data centres could generate £14.6 billion by 2030, while sovereign cloud services could be worth a further £13.6 billion over the next five years.
Cloud offer
The new Sovereign Cloud service is a private cloud platform hosted and operated entirely within the UK. It is aimed at organisations handling sensitive or regulated workloads and includes compute, storage and backup services.
The platform uses Rackspace Technology data centre infrastructure in the UK, supported by UK-based security-cleared teams providing managed services for migration, operations and compliance.
Alongside the cloud service, BT is developing sovereign AI services with Nscale and NVIDIA. These are intended to let customers run AI workloads in the UK, expand computing capacity when needed, and meet data residency, security and regulatory requirements.
BT said the AI offer is intended for uses including operational automation, advanced analytics and AI-assisted customer service. It presented the wider portfolio as a way for organisations to modernise critical services while retaining greater operational control.
Economic case
Assembly Research also modelled potential savings from risk reduction and compliance. It estimated that greater control over data and digital systems could cut losses linked to cyber incidents by about £632 million a year.
The study found that wider adoption of domestically controlled systems could also make it easier for organisations to comply with UK data protection rules and sector regulation, helping businesses avoid as much as £1 billion in GDPR-related fines.
Digital sovereignty has risen up the policy agenda in the UK and across Europe as governments and businesses examine their dependence on overseas digital platforms and infrastructure. BT's launch reflects growing demand from public bodies and private companies for clearer controls over where data is held, who manages systems, and how services are governed.
BT Business Chief Executive Officer Jon James said customers wanted to adopt AI and cloud services quickly while maintaining control over their data. "Organisations, public and private, want to move fast with AI and cloud while keeping control over the sovereignty of their data. That's why BT is the first UK provider to offer a complete sovereign portfolio - from secure connectivity and voice to sovereign cloud and AI - all delivered in one place. Only BT has the scale and infrastructure to help customers modernise critical services with confidence, delivering real benefits for organisations and for the UK as a whole," James said.
Assembly Research Founder and Chief Executive Matthew Howett said the policy backdrop had become more urgent. "Our research shows that digital sovereignty has become a political focus across Europe and in the UK, as concerns about an over-reliance on non-sovereign digital platforms have intensified. The clear prize on offer should encourage the Government to take further steps to realise the opportunities of a wider adoption of digital sovereignty. As well as the potential economic benefits, the wider adoption of digital sovereignty promises enhanced resilience by giving organisations more control over services," Howett said.
