Government admits its approval for Buckinghamshire AI datacentre should be quashed
The UK government has withdrawn planning consent for a large AI datacentre on greenbelt land in Buckinghamshire, acknowledging that it failed to properly assess climate impacts. The reversal follows a legal challenge by environmental campaigners and highlights tensions between tech investment ambit…
The Department for Housing, Communities and Local Government announced on Monday that the planning permission granted for a hyperscale artificial‑intelligence datacentre in Buckinghamshire must be revoked. The decision comes after the government conceded that it had not carried out a sufficient environmental impact assessment and that the original approval was therefore unlawful.
Background to the controversial approval
In early 2024, former Deputy Prime Minister Angela Rayner overruled objections from the local council and signed off on a development known as the West London Technology Park. The site, a 72,000‑square‑metre former landfill in Iver, lies on greenbelt land adjacent to the M25 motorway. The project was promoted as a flagship AI hub capable of drawing up to £1 billion of foreign direct investment and was framed as a concrete step toward the Labour government’s pledge to accelerate private investment in artificial‑intelligence infrastructure.
At the time, the government had recently classified AI‑focused datacentres as “critical national infrastructure”, a move intended to streamline planning procedures and signal the sector’s strategic importance to the British economy. Former Technology Secretary Peter Kyle described such facilities as “the engines of modern life”, emphasizing their role in powering the digital economy and safeguarding personal data.
Legal challenge and environmental concerns
Environmental groups, including Global Action Plan and the tech‑equity organisation Foxglove, filed a legal challenge in the High Court, arguing that the approval ignored the datacentre’s likely carbon emissions, water consumption and overall energy demand. They contended that the government had relied too heavily on the developer’s assurances without demanding a robust, independent assessment of the site’s climate impact.
During the hearing, the court highlighted that the planning authority had failed to consider the cumulative effect of a large‑scale, energy‑intensive facility on a greenbelt area already under pressure from development. The judges questioned the adequacy of the evidence presented by Greystoke, the developer, which declined to comment publicly on the proceedings.
Government admission and the U‑turn
Steve Reed, the current Secretary of State for Housing, Communities and Local Government, addressed the court and admitted that the decision to forgo a formal environmental impact assessment was “inadequate”. He described the original approval as a “serious logical error” and confirmed that the Secretary of State would concede the challenge, effectively quashing the permission.
The admission marks a sharp reversal from the earlier stance that had prioritized rapid rollout of AI infrastructure over traditional planning safeguards. Campaigners hailed the move as a “embarrassing climb‑down” for ministers who, in their view, had placed the interests of multinational tech investors above local communities and environmental stewardship.
Implications for UK datacentre strategy
The case arrives at a time when the UK’s datacentre capacity is projected to increase dramatically. Government analysis estimates that the nation had roughly 1.6 gigawatts of datacentre capacity in 2024, a figure expected to quadruple by 2030 to meet growing demand for AI training and cloud services. However, the rapid expansion has raised concerns about water scarcity, grid reliability and the carbon footprint of data‑intensive operations.
Critics argue that the government’s earlier push to label AI datacentres as critical national infrastructure risked sidelining essential environmental safeguards. They point to the need for a more balanced approach that integrates climate resilience into the planning process, especially for facilities sited on greenbelt or former landfill sites where ecological sensitivity is high.
Reactions from stakeholders
Rosa Curling, co‑executive director of Foxglove, warned that the episode illustrates a broader pattern of ministers favouring “Trump‑supporting tech billionaires” over public interest. She called for stricter scrutiny of developers’ carbon‑reduction pledges before any future approvals are granted.
Sonja Graham, chief executive of Global Action Plan, added that the government’s “sleeping at the wheel” undermines public confidence in the nation’s ability to manage the environmental costs of a digital economy. She urged policymakers to develop clear guidelines for water usage, renewable‑energy sourcing and carbon accounting for all large‑scale datacentres.
Greystoke, the company behind the Iver project, has not responded to requests for comment since the court hearing.
What comes next?
With permission now quashed, the developer must return to the planning board and submit a revised application that includes a comprehensive environmental impact assessment. The government has indicated it will work with local authorities to ensure any future proposals meet both economic and sustainability criteria.
Meanwhile, the broader debate over how to balance the UK’s ambition to become a global AI hub with its climate commitments continues. Industry bodies are calling for clearer, faster pathways for datacentre construction, while environmental NGOs are pressing for mandatory climate‑impact reviews and stronger community consultation processes.
As the sector races toward the projected 2025‑2030 capacity surge, the Buckinghamshire case may serve as a precedent for how the UK reconciles high‑tech growth with its legal and moral obligations to protect the environment.
Why it matters
The reversal underscores the tension between the UK’s AI‑driven economic ambitions and the need for rigorous environmental oversight of large‑scale datacentre projects.
Key points
- Government admits original planning consent for Buckinghamshire AI datacentre was unlawful due to inadequate climate assessment
- Legal challenge by environmental groups forced a U‑turn on the approval of the West London Technology Park
- The case highlights growing scrutiny of datacentre energy use, water demand and carbon emissions in the UK
- Future AI infrastructure projects may now require mandatory environmental impact assessments
- The decision could reshape how the UK balances tech investment with climate commitments
Frequently asked questions
Why was the planning permission for the Buckinghamshire AI datacentre revoked?
The government acknowledged that it had not carried out a proper environmental impact assessment and that the original decision failed to consider the project's climate and water‑use implications, making the approval unlawful.
Who challenged the datacentre approval in court?
Environmental charities Global Action Plan and the tech‑equity group Foxglove, among others, filed a legal challenge arguing the approval ignored the facility’s carbon footprint and resource demands.
What does the revocation mean for the developer, Greystoke?
Greystoke must submit a new planning application that includes a thorough environmental impact assessment and address the concerns raised by the court and local stakeholders.
How does this case affect the UK’s broader AI datacentre strategy?
It signals that rapid rollout of AI infrastructure cannot bypass environmental safeguards, potentially leading to stricter planning rules for future datacentre projects.
