Local market context
Colt London 4 within the London market.
London is Europe's largest data centre market, built on two clusters: the Docklands and East London exchanges that anchor financial connectivity, and the West London corridor through Park Royal, Hayes and the Slough fringe that took most of the hyperscale build. Grid capacity in West London is now the constraint, so new demand is spilling into outer boroughs, the M4 corridor and regional hubs. The London Docklands cluster, anchored by Telehouse London and the London Internet Exchange (LINX), remains the dense colocation and interconnection core, while West London hosts large hyperscale data centre campuses and new data halls. The capital remains Europe's primary digital infrastructure hub.
