Green Grid, Red Tape: How Regulation Holds Back (and Can Unlock) UK Data Centres

Written By Zara Ward

Every time we tap a card, stream a video, log into online banking or train an AI model, a data centre makes it possible. Once seen as anonymous server sheds, they are now recognised by the UK Government as Critical National Infrastructure (CNI), putting them on the same footing as roads, hospitals and power stations.

The UK’s data centre sector is already worth over £8 billion a year [1], with more than 477 operational facilities [2] and annual growth of 5% or more [3]. Demand is accelerating, fuelled by artificial intelligence, cloud adoption, streaming and e-commerce.

Yet projects across the country are stalling. Not because of a lack of investment, but because of bureaucracy. At the heart of the problem lies a contradiction: the UK champions itself as a digital-first economy, but the infrastructure that powers that vision is entangled in red tape.

The Problem: When Red Tape Bites

Two barriers dominate the landscape:

  1. Planning Delays:

One of the biggest hurdles for UK data centres is planning. Local authorities, particularly in London and the South East, often lack the expertise and resourcing to assess complex large-scale applications. A 2025 survey of over 3,000 industry professionals, commissioned by BCS (The Chartered Institute for IT), found planning delays were the single largest barrier to growth [4]. Projects that should move quickly often languish for years as councils weigh national priorities against local opposition.

The effects are clear. In the South East’s “Data Centre Alley” between Slough and Reading, multi-hundred-megawatt projects have been locked in stalemate, as local planners wrestle with concerns regarding land use, visual impact and power consumption.

      2. Grid Connection Queues:

Beyond planning challenges, the electricity grid queue is under strain, with hundreds of projects waiting years for access. Some developers have been told they will not connect until the 2030s.

The consequences are serious. In 2025, Microsoft warned that its £2.5 billion UK expansion across London, South Wales and Northern England could be jeopardised because of grid delays, with some sites facing connection dates a decade away [5]. Developers such as Segro have voiced similar concerns, warning that the lack of access to power is fast becoming a major risk to investment [6].

The National Energy System Operator (NESO) has begun reforms, removing inactive projects and shifting towards a “first ready, first connected” model, but until those changes bite, the grid remains a strategic bottleneck for both digital growth and renewable energy integration.

What Works: When Regulation Enables

The UK does not have to accept gridlock as inevitable. Where regulation has been clear and consistent, the results speak for themselves.

For example, over the past two decades, Slough has grown into one of Europe’s largest data centre hubs [7]. This did not happen by accident. Local councils put in place clear planning frameworks and worked closely with developers to give investors confidence and help balance community concerns. The result is a thriving cluster that continues to attract new investment.

There are also indications of progress being made in sustainability. Several operators in London and the South East are working with councils to capture heat waste from data centres and feed it into community heating schemes [8]. These projects build trust with local residents, demonstrate environmental responsibility and show how growth can be tied to tangible public benefit.

Momentum is also shifting outside the South East. In 2025, North Lincolnshire Council backed plans for a 1GW AI-focused campus on a former RAF site at Elsham Wolds [9]. With strong local support and clear alignment with national policy, the project shows how proactive planning can turn underused land into digital infrastructure of global significance.

The lesson is simple: when regulation provides clarity and creates incentives, the industry responds with innovation and collaboration.

From Red Tape to Green Light: What Needs to Change

If data centres are to be treated as national infrastructure, the way we regulate them must continue to evolve. To meet growing demand effectively, the UK must invest in comprehensive, forward-thinking solutions rather than rely on incremental fixes. Four areas stand out:

  1. Faster, more consistent planning: Critical digital infrastructure should be assessed with the same urgency as hospitals or transport projects. This requires clear national guidance and proper resourcing for local authorities, so that applications do not remain pending for years.

  2. Grid connections as a shared priority: NESO’s decision to remove inactive projects from the queue is a welcome start, but deeper change is needed. Utilities and data centre operators must collaborate and co-invest in renewable generation and transmission upgrades to ensure capacity grows in step with demand.

  3. Stable and consistent policy: Stop–start restrictions undermine confidence. A clear, long-term roadmap that balances digital growth with the UK’s net zero commitments would provide the certainty investors and developers need.

  4. Building trust with communities: Transparency on energy, water use and emissions should be standard. Incentives for circular solutions such as recycling heat waste and water would demonstrate that data centres can contribute positively to local areas.

In short, regulation should not be viewed as bureaucracy. Done well, it is a steering mechanism. Poorly designed frameworks create gridlock; well-designed frameworks unlock growth and sustainability together.

Conclusion

Data centres may be out of sight, but they are no longer out of mind. They are the backbone of our digital economy, essential for AI, fintech, healthcare and government services. The UK now faces a choice; continue with red tape that leaves projects stranded in queues until the 2030s, or embrace smart regulation that provides the green light to sustainable digital growth. The stakes are high. Without change, the UK risks bottlenecks that undermine its digital and AI ambitions. With change, we can ensure our digital backbone is as resilient, sustainable and competitive as our national aspirations demand. The real question is: will government and industry move quickly enough to deliver it?
