UK Needs Earlier, Joined-Up Planning to Unlock Land for Data Centres, Aecom Argues

Why It Matters

Without coordinated planning the UK risks losing AI‑intensive workloads to cheaper, faster markets, while strategic action could turn data centres into engines of regional growth and decarbonisation.

Key Takeaways

• Grid reinforcement delays outpace data‑centre construction speed
• “Powered land” concentration shifts from London to repurposed sites
• On‑site renewables and waste‑heat reuse cut power costs
• Water demand manageable via closed‑loop cooling and recycled sources
• Early multi‑stakeholder planning essential for AI and regional growth

Pulse Analysis

The United Kingdom is witnessing an unprecedented surge in data‑centre construction, driven by AI workloads and digital sovereignty goals. Yet the traditional, reactive planning model struggles to keep pace with the speed at which developers can secure sites. The concept of "powered land"—parcels equipped with sufficient electricity, water and planning consent—has become a critical metric, and its scarcity in the South‑East is inflating land and connection costs. By shifting focus to under‑utilised industrial estates and logistics parks near existing transmission infrastructure, the country can alleviate pressure on hotspot regions and unlock new investment corridors.

Addressing the power bottleneck requires more than just faster grid connections; it demands a holistic redesign of the energy supply chain. Aecom recommends outcomes‑led grid reform that abandons first‑come‑first‑served queues, improves transparency on capacity, and prioritises projects aligned with national energy objectives. Complementary solutions such as on‑site solar, battery storage, micro‑grids and even small modular reactors can provide reliable power while reducing reliance on the national grid. Simultaneously, modern closed‑loop cooling systems and the reuse of treated wastewater diminish water constraints, turning a perceived limitation into a commercial opportunity for water utilities. Integrating waste‑heat into district‑heating networks further enhances the environmental profile of data centres and builds local community support.

The strategic stakes extend beyond infrastructure. By establishing a sovereign data‑centre framework and clear demand signals for public‑sector workloads, the UK can retain high‑value AI training activities domestically. Coordinated planning that aligns data‑centre siting with regional skills development, energy regeneration and economic regeneration policies will transform these facilities from isolated power‑hungry assets into anchors of regional prosperity. In this context, early, multi‑stakeholder collaboration emerges as the decisive factor that will determine whether the UK capitalises on its digital ambitions or cedes them to lower‑cost jurisdictions.
