Datacenters in London Metro

47 facilities in this metro.

London is one of Europe’s two largest colocation markets and the natural landing point for transatlantic connectivity. LINX and a deep carrier ecosystem give the metro exceptional interconnection choice, and the financial-services cluster keeps demand for low-latency, high-resilience capacity structurally high.

Capacity is spread across distinct submarkets: Docklands and the City for interconnection-dense sites, and the western corridor — Slough and the M4 belt — for larger campuses where much of the newer, higher-density inventory is built. Power availability in West London has been a constraint in recent years, which makes delivery timelines and secured grid connections a key question to put to operators.

Post-Brexit, the UK sits outside the EU’s legal framework; UK GDPR remains closely aligned, but organisations with strict EU-data-residency requirements sometimes pair a London deployment with an EU metro. The snapshot below shows how the listed London inventory compares on power bands, cooling and certifications — a practical starting point before you request proposals.
