In an age of instant connectivity, artificial intelligence (AI), and cloud services, data centres form the invisible backbone of the UK economy, writes Adam Eaton, CEO of VIRTUS Data Centres.
Streaming, online banking, NHS services, or AI-driven decisions depend on these facilities to process, store, and secure vast data volumes. A robust domestic data centre sector is essential for digital sovereignty, low-latency performance, and reduced reliance on foreign providers, enabling the UK to compete globally while advancing energy sustainability goals.
The digital backbone of modern life
Data centres have evolved from niche industrial sites into the central nervous system of the economy. UK households and businesses rely on them daily for everything from online shopping to remote work, to digital education, and virtual healthcare. The transition to electric vehicles further underscores their importance. It’s data centres that process enormous datasets for battery optimisation, charging networks, software updates, and real-time monitoring, enabling safe, efficient integration with the national energy grid.
AI adoption is accelerating this demand. Financial services use machine learning (ML) for fraud detection and trading, manufacturers deploy edge computing for smart factories, and public sector systems handle petabytes of sensitive data. Onshore capacity ensures compliance with GDPR, and emerging data protection rules, enhances cybersecurity, and minimises geopolitical risks. Proximity to high-density compute also fuels innovation in fintech hubs, European AI research, and advanced manufacturing.
Economic and regional regeneration benefits
Beyond technology, data centres deliver substantial economic and social value. They support thousands of skilled jobs in engineering, construction, facilities management, and IT. According to PwC, each direct role generates more than six additional positions across the supply chain. The sector anchors broader ecosystems, attracting investment in AI, cybersecurity, and high-performance computing while boosting national competitiveness and productivity.
Looking at one of our facilities as an example – VIRTUS’ Saunderton Campus in Buckinghamshire was once a derelict former tobacco machine factory. Unused for 15 years, it is now being transformed into a 78MW AI-ready development across 50 acres, with much of the land given back to nature. So, far from the myth that a choice has to be made between building homes and building data centres, brownfield and industrial land is increasingly being used and encouraged for new facilities to regenerate sites rather than compete with housing.
Slough is one of Europe’s largest data centre hubs due to its fibre connectivity and customer demand. It has replaced declining manufacturing jobs on a near one-to-one basis, generating significant business rates. And contrary to the belief that data centres can only be build in London, new hubs that are emerging beyond the capital are experiencing similar benefits. Projects in Greater Manchester, South Wales, the North East, and Scotland are repurposing industrial sites, aligning with renewable energy sources, and creating future-proof employment. With supportive policy, data centres can drive balanced growth from London hubs to emerging regional clusters.
Sustainable investments and renewable leadership
The UK data centre industry is committing major private capital to build resilient, sustainable capacity. VIRTUS alone has invested £1.7 billion to date and plans a further £2.7 billion over the next five years. The broader industry pipeline stands at approximately £36.4 billion for nearly 100 projects as of mid-2025.
Sustainability is central to these efforts. VIRTUS was the first UK operator to achieve 100% renewable energy sourcing and pursues a net zero emissions strategy. Commitment to long term renewable purchasing via Power Purchase Agreements (PPAs) illustrates how data centres can stimulate renewable generation by providing stable demand for new wind, solar or hydro projects. Industry-wide shifts toward efficient cooling, higher rack densities, and on-site innovations are lowering carbon intensity and water use.
Addressing challenges for long-term success
Despite momentum, challenges remain. Planning delays hinder viable projects despite a 63% surge in applications in 2025. Grid connection queues – sometimes exceeding 15 years – must be tackled through reforms prioritising strategic AI and digital infrastructure. High industrial electricity prices, among Europe’s highest, risk deterring investment. This means that competitive pricing alongside grid upgrades is essential.
A stronger talent pipeline is also critical. Vocational training, apprenticeships, and industry-college partnerships can address skills gaps amid an ageing workforce. Upgraded fibre networks beyond London will support regional hubs and edge computing. techUK projects that addressing these enablers could deliver an additional £44 billion in gross value added (GVA) and over 58,000 jobs between 2025 and 2035.
Towards a sovereign, sustainable digital future
Data centres are no longer optional. They are critical national infrastructure and cornerstones of success in the AI era. With billions in investment, renewable commitments, and innovation in efficiency, the sector is poised to power everyday life, regenerate regions, and enhance UK competitiveness.
