Uptime Institute Tier III data centers in United Kingdom

Facilities in United Kingdom that publish Tier III certification. Concurrently maintainable design: any capacity component can be taken out for service without shutting down IT load. The practical floor for production workloads.

11 of the 196 facilities we track in United Kingdom publish Tier III — 9 operators, 36 MW of published IT capacity, 11 operational. Cities: Glasgow (Chapelhall), London, Cardiff, Aberdeen, Birmingham, Harrogate, Dunstable, Debden.

For context, wholesale colocation in United Kingdom is benchmarked at $213 per kW per month (CBRE, Global Data Center Trends 2026 (17 June 2026), Fig. 5 — Q1 2026, 250–500 kW), and commercial electricity at $0.454 per kWh — certification rarely changes the rack rate, but it narrows the shortlist.
