For much of the past decade, the UK’s approach to digital infrastructure has been shaped by a simple assumption: that hyperscale cloud providers operate as neutral global utilities, largely insulated from politics.
Today, that assumption is being challenged.
As geopolitical tensions rise and regulatory scrutiny intensifies, the question of data sovereignty in the UK is becoming increasingly important. Businesses are asking where their data is stored, who ultimately has access to it, and how resilient their infrastructure really is in an unpredictable global environment.
For many organisations, the conversation around digital infrastructure has moved well beyond technology. It is now a strategic issue that touches governance, compliance and national resilience.
Why data sovereignty is moving up the agenda
Recent geopolitical developments have highlighted just how interconnected global technology supply chains have become. Trade tensions between the United States, the UK and Europe have exposed the reality that digital infrastructure does not sit outside politics.
At the same time, legislation such as the US Cloud Act has introduced new complexities. The law allows US authorities to access data held by American companies, regardless of where that data is physically stored. For organisations operating in regulated industries, this creates legitimate concerns about jurisdiction and control.
Unsurprisingly, attitudes are beginning to shift.
Our research shows that more than half (52%) of UK IT decision-makers now plan to reduce their reliance on US-based cloud providers. Concerns about data sovereignty and data residency were cited by an overwhelming majority of respondents, while nearly half (45%) said they are actively seeking to limit exposure to US jurisdiction in response to geopolitical developments.
This change in sentiment reflects a growing recognition that infrastructure decisions are not simply technical choices – they are risk management decisions.
The reassessment of the cloud-first era
For many organisations, the last decade was defined by the rapid adoption of cloud computing. Public cloud platforms promised flexibility, scalability and cost efficiency, and for many workloads they delivered exactly that.
However, experience has also revealed some of the limitations of a blanket “cloud-first” approach.
Many organisations are now reassessing where different workloads should sit. Cost pressures have played a role, with a significant number of organisations reporting higher-than-expected cloud operating costs. But concerns around governance, performance and control are also driving change.
As a result, many businesses are now embracing hybrid infrastructure models, combining cloud platforms with colocation facilities and on-premise environments. In fact, our research found that the vast majority of organisations are already in the process of bringing at least some workloads back from public cloud environments.
Rather than abandoning the cloud, organisations are becoming more strategic in how they use it.
When data centres become critical national infrastructure
Another development has significantly reshaped the conversation around digital infrastructure.
In 2024, the UK Government formally designated data centres as Critical National Infrastructure. This recognition places them alongside sectors such as water, energy and healthcare – industries whose disruption would have serious consequences for society and the economy.
The designation reflects the reality that digital infrastructure now underpins almost every part of modern life. Financial services, healthcare systems, transport networks and government operations all rely on secure and resilient data centre capacity.
Despite this, public understanding of data centres is still widely off the mark. We recently commissioned a study of 2,000 UK adults which found that 85% are not fully confident in their understanding of data centres, with 40% who have heard of them believing they mainly benefit big tech companies rather than ordinary people and 53% admitting they do not understand what a data centre is.
As critical infrastructure, the conversation needs to broaden and the government, alongside the industry, has to do more to educate the public on how they support our digital economy.
A growing gap between policy and industry strategy
While awareness of data sovereignty is increasing among the private sector, the UK government has been slower to adapt.
Countries such as France, Germany and several Nordic nations have taken a more explicit approach to digital sovereignty, treating domestic digital infrastructure as a strategic national asset. These countries increasingly see data centres as part of national resilience and economic competitiveness.
The UK, by contrast, has continued with its long-standing “cloud-first” policy through procurement frameworks that strongly favour large hyperscale providers for government contracts over local providers.
Recent planning announcements involving Amazon Web Services and Microsoft highlight the scale of hyperscale investment in UK digital infrastructure.
These investments bring innovation and capability, but they also underline the UK’s growing reliance on foreign-owned platforms when we can utilise our own.
Sovereignty is about choice, not isolation
Discussions about digital sovereignty are sometimes misinterpreted as calls for technological isolation. In reality, the issue is far more nuanced.
Global cloud platforms will continue to play a vital role in enabling innovation. However, organisations increasingly want to ensure they retain choice in how and where their most critical workloads are hosted.
Sensitive data, regulated services and national infrastructure should be capable of being managed within legal and operational frameworks that UK organisations understand and control.
This flexibility is becoming even more important as artificial intelligence adoption accelerates. AI workloads tend to be highly data-intensive and latency-sensitive, often requiring secure environments close to the point of data creation itself.
For many organisations, this is reinforcing the value of local infrastructure and colocation environments as part of a broader hybrid strategy.
The economic importance of domestic infrastructure
Beyond resilience and sovereignty, there is also a strong economic argument for strengthening domestic digital infrastructure.
Data centres underpin the UK’s digital economy. They enable everything from financial transactions and healthcare systems to emerging technologies such as artificial intelligence and smart infrastructure.
UK-based data centre providers invest in local communities, support skilled jobs and contribute to national tax revenues. They also help distribute digital capacity beyond already congested metropolitan areas, supporting regional economic growth.
Against a backdrop of tightening energy constraints, rising cyber threats and geopolitical uncertainty, maintaining strong domestic infrastructure capacity is becoming increasingly important.
Time for a more balanced infrastructure strategy
The lesson from the past decade is not that cloud has failed. Rather, it is that one-size-fits-all infrastructure strategies no longer work.
Organisations today must balance competing priorities including cost efficiency, resilience, regulatory compliance and data sovereignty.
The most successful strategies are those that maintain flexibility, allowing organisations to match workloads to the environments best suited to them.
For policymakers, the challenge is similar. Supporting hyperscale innovation does not have to come at the expense of domestic capability.
A more balanced approach that recognises UK data centres as strategic infrastructure would better reflect the realities facing today’s CIOs.
A practical issue, not a theoretical debate
Digital sovereignty is no longer a theoretical debate taking place in policy papers or conference panels.
It is now a practical, operational issue playing out in boardrooms across the UK.
As the global landscape becomes more uncertain and digital infrastructure becomes ever more critical to economic stability, organisations and policymakers alike will need to rethink how infrastructure decisions are made.
The real question is no longer whether the UK should reconsider its approach to digital infrastructure – but whether it can afford not to.
