What Is Data Sovereignty?
Data sovereignty is the principle that digital data is subject to the laws of the country where it is collected and processed. For UK businesses, this means understanding which regulations govern the data you hold, where that data is physically stored, and what obligations apply when using cloud providers that may process data outside UK borders.
In September 2024, the UK government designated datacentres as critical national infrastructure (CNI), placing them alongside energy networks, transport systems, and water supply in terms of strategic importance. The move signals a deliberate intent to strengthen oversight and resilience in the UK’s data infrastructure.
What the CNI Designation Means in Practice
Designating datacentres as CNI brings with it an expectation of enhanced cybersecurity standards, clearer incident reporting obligations, and investment in resilience and disaster recovery capability. For businesses that rely on UK-based datacentres, this should mean a more robust and better-regulated environment for data storage and processing.
The designation also reflects the government’s concern about the UK’s dependence on a small number of large foreign cloud providers. Amazon Web Services, Microsoft Azure, and Google Cloud collectively handle a substantial proportion of UK business data. Their infrastructure is predominantly owned and operated outside the UK, which creates questions about jurisdiction, data access, and what happens if a major provider experiences a significant outage or legal challenge.
What This Means for Your Business
Understand where your data is stored
If your business uses cloud services, you should know which country your data is being processed in. Most major providers offer the option to specify a UK or European region for data storage. Confirming this is in place and documented is a straightforward step with compliance implications, particularly for businesses holding client data subject to UK GDPR.
Review your cloud provider dependencies
Concentration risk is worth considering. If your entire operation runs through a single cloud provider, a major outage or policy change by that provider has an outsized impact on your business. A review of your cloud architecture and whether any diversification is appropriate is a sensible exercise.
Keep pace with regulatory change
The CNI designation is a signal of direction rather than a completed framework. Further regulation of data infrastructure is likely to follow. Businesses that stay informed about how UK data law develops will be better placed to adapt without disruption.
