Data centre campus, Hayes Bridge and Heathrow Interchange
The London Borough of Hillingdon approved hybrid application 78343/APP/2025/719 on 29 October 2025 for a four-phase redevelopment of Hayes Bridge Retail Park and Heathrow Interchange into a data centre campus. Phase 1 has full planning permission for a data centre building with energy, power and water infrastructure and site access works. Phases 2 to 4, comprising an innovation hub and two further data centre buildings, are approved in outline with all matters reserved. The register states no electrical capacity, so none is recorded.
