Data centres in operation tend to draw little public interest. They work in the background, keeping the digital world running without drawing attention to themselves. Yet as soon as a new planning notice appears, that all changes, with multiple questions about noise, traffic and land use arising simultaneously.
Much of the unease comes from a simple knowledge gap: people rarely see what happens behind the secure doors of a modern facility, so they rely on headlines to fill the void.
That gap matters more now than ever – not just because data centres are growing in number, but because they’re being built closer to where people live and work. The 2024 update to the National Planning Policy Framework introduced the idea of the grey belt – green-belt land that is either previously developed or scores weakly against the five green-belt purposes. In practice it means that, where strict tests on need and sustainability are met, critical infrastructure such as data centres can be approved on sites that would once have been off-limits.
The policy has already helped to deliver landmark approvals such as at South Mimms and Abbotts Langley in Hertfordshire, and at Court Lane in Iver, Buckinghamshire. Yet, the designation removes only the first barrier; an application still stands or falls on local goodwill. What happens next depends not just on planning rules, but on how well the community is brought into the process from the start.
The path to planning success starts with earning trust, and that starts with listening. Opening conversations with parish councillors, residents’ groups and neighbouring businesses months before the formal process invites the community to help shape the design rather than to react to it.
Those early discussions create space to share practical detail. Demonstrating how closed-loop adiabatic systems use harvested rainwater for most of the year, or explaining that emergency generators run only for brief, regulated tests on cleaner fuels, shows that modern facilities are designed to tread lightly. Publishing grid-connection schedules alongside local reinforcement plans further reassures people that the existing supply will stay secure.
Clear language is as important as technical performance. Translating environmental data into everyday comparisons – for example, explaining that predicted noise sits between a kitchen extractor fan and a suburban street at rush hour – turns abstract numbers into something people can picture. The same goes for transport: a 100-megawatt campus typically attracts fewer daily vehicle movements than an equivalent distribution warehouse, keeping peak-time traffic flowing.
When the benefits are tangible, interest quickly shifts from concerns to opportunities. Apprenticeships, high-skill careers and steady business-rates revenue resonate far more than acronyms. Framing the campus as an “AI factory” links it to life-sciences breakthroughs, cleaner transport and advanced manufacturing, reinforcing the idea that the project is an asset for the whole region.
Early engagement also determines how much a community gains. The construction phase alone sustains hundreds of jobs and apprenticeship placements; once operational, a typical large-scale campus supports in the region of two hundred high-skill roles across engineering, IT, security and facilities management, with wages well above local averages.
Councils value the associated business-rates revenue and often agree direct contributions to public amenities. Contributions can include funding for extensive green space and workforce development support – tangible evidence that digital infrastructure can enhance the physical environment when developers and authorities plan together.
Developers such as Ark Data Centres are putting sustainability at the heart of their design approach – using a factory-focused modular building process that favours steel over concrete, enabling 90% of the building to be recycled. Rainwater harvesting can also be incorporated, with some new sites able to run entirely on recycled rainwater. These are just a couple of the methods which Ark uses to construct socially responsible data centres.
By joining local-plan reviews early, operators can help councils weigh digital infrastructure alongside residential growth rather than bolt it on later. Grey-belt flexibility is unlikely to last indefinitely; ministers have already signalled that the policy will be reviewed within the life of the current Parliament. Projects conceived now therefore need to advance at speed, and the smoothest route is through cooperation, not confrontation.
All of this leads to a single conclusion: engagement is not a formality pinned to the end of an application, it is the foundation on which the project rests. By meeting communities where they are, translating engineering into everyday language and designing schemes that deliver visible local value, we shorten the distance from stranger to neighbour. When that happens, Britain’s digital infrastructure can grow with less friction and with benefits that extend far beyond the data-hall walls.
