Developers Submit £1.2bn Plan for Regional AI Data Centre Campus

Developers have submitted planning applications for a £1.2 billion data centre campus outside the UK's traditional digital corridors.

The proposed facility reflects sustained operator migration into secondary regional markets as land and electrical capacity tighten across the south-east of England. The primary European hubs—Frankfurt, London, Amsterdam, Paris, and Dublin—face acute power interconnect constraints. In London, substation capacity along the M4 corridor has become heavily rationed, prompting operators to seek high-voltage connections at regional transmission nodes.

Under the blueprints, the multi-building campus will deliver dedicated high-density halls engineered for artificial intelligence training and inference workloads. The mechanical specifications account for rack power densities exceeding 40 kilowatts, incorporating hybrid liquid-to-chip cooling loops alongside external heat rejection systems. Phased construction is scheduled over multiple years, contingent upon local planning approval and energisation dates from the transmission network operator.

Power availability remains the primary factor governing the project's timeline. Transmission-level interconnections have become the principal hurdle for UK infrastructure deployments, with standard queue estimates frequently stretching past 2030. Moving into secondary regions avoids congested urban distribution networks. Even so, these projects require dedicated substations and substantial grid reinforcements to maintain continuous baseload power without destabilising local supply.

The development arrives amid greater national scrutiny of compute infrastructure. The UK government recently classified data centres as Critical National Infrastructure, a designation intended to deter planning blockages and prioritise site protection. Even with this backing, municipal planning committees must balance multi-hundred-megawatt electrical demands against modest long-term site employment once construction concludes.

As regional authorities assess the trade-off between major grid draw and local economic yield, can national transmission upgrades keep pace with the sector's regional push?
