London Colocation FAQs

Why is London Europe's largest data centre market?
London is the financial capital of Europe, home to LINX (one of the world's largest internet exchanges), and the natural landing point for transatlantic and European submarine cables. Demand is driven by financial services, content delivery, cloud connectivity (AWS Europe London, Azure UK South, GCP London), and AI/HPC growth. The market spans 274 facilities operated by 110 providers, with 1.6 GW of upcoming capacity.
Slough vs Docklands — which is right?
Slough wins for financial trading — Equinix's LD4-LD9 campus is anchored by the Hibernia Express cable for sub-59ms RTT to NYC, critical for HFT. Slough also offers larger floor plates and cheaper power than Central London. Docklands wins for interconnection density — LINX peering, Telehouse North/East/West, and the highest carrier diversity in the UK. Most enterprise tenants pick one or the other based on whether financial latency or peering matters more.
What is Telehouse West Two?
Telehouse's £275m (US$370m) purpose-built 9-storey expansion in Docklands, currently under construction. It combines air and liquid cooling to support high-density AI and HPC deployments. When complete, it will be one of the most advanced AI-ready facilities in London, extending Telehouse's interconnection ecosystem into modern density requirements.
Is the Royal Docks worth considering?
Yes — particularly for AI workloads. Ada Infrastructure's 210 MW campus has set the bellwether with planning approval that integrates community skills hubs and river-water cooling. The Royal Docks district offers proximity to Docklands fibre paths (so you keep low-latency to LINX) but lower land costs and bigger footprints. Digital Reef and Tritax Big Box are following with similar AI-focused builds.
What about other UK locations?
Manchester (MA1, MAN1) is the secondary UK colocation hub, useful for tenants who need UK presence outside London or geographic diversity. Manchester also offers significantly cheaper power and land. Edinburgh and Cardiff have small clusters but lack the operator density of London. For most tenants, London (Slough or Docklands) is the default choice.
