Why use CageLab instead of contacting providers directly?
Finding colocation space directly can mean chasing multiple operators, repeating the same requirements and comparing quotes that are not built on the same assumptions. CageLab helps you define the requirement first, then narrow down providers that fit.
Compare providers using the same technical requirements
Define power, rack size, location, compliance and connectivity once. Compare only the operators that genuinely match.
Avoid wasting time on unsuitable facilities
Filter out providers that do not support your workload, density or resilience needs before any calls.
Clarify requirements before sales calls
Enter every operator conversation with a clear, consistent brief. Reduce back-and-forth and scope drift.
Include regional UK options, not only London names
Manchester, Birmingham, Slough, Edinburgh, Cardiff and other UK regions are in the comparison set.
Stay in control of who you speak to
You choose which matched providers to meet. No obligation and no pressure to accept any introduction.
