London Data Centre FAQs

Why is Docklands the UK's primary data centre hub?
Docklands — particularly the area around Canary Wharf — is home to Europe's most interconnected data centre campus. It hosts LINX (London Internet Exchange), one of the world's largest IXPs, along with dense fibre networks and direct peering with major carriers. Proximity to the City of London's financial district makes it the natural home for latency-sensitive trading and enterprise workloads.
How does Slough compare to central London for colocation?
Slough Trading Estate offers significantly more space and power capacity at lower cost than central London facilities. It sits on major fibre routes between London and the transatlantic cable landing stations, providing excellent connectivity. For workloads that don't require sub-millisecond City access, Slough delivers better value with enterprise-grade reliability and room to scale.
What are the GDPR and data sovereignty requirements for UK colocation?
Post-Brexit, the UK operates under its own UK GDPR framework, which mirrors EU GDPR but is governed independently by the ICO. The UK has an EU adequacy decision enabling data flows between the UK and EU. Many organisations choose London specifically to maintain both UK and EU data sovereignty compliance, with facilities offering dedicated sovereign cloud environments and data residency guarantees.
