ISO/IEC 27001 data centers in United Kingdom

Facilities in United Kingdom that publish ISO 27001 certification. The baseline information-security certification most enterprise procurement teams require before a facility can host regulated workloads. It certifies the operator runs a documented information security management system, audited annually.

47 of the 196 facilities we track in United Kingdom publish ISO 27001 — 15 operators, 82 MW of published IT capacity, 47 operational. Cities: London, Reading, Dartford, Havant, Cardiff, Corsham, Farnborough, Slough, Woking, Crawley, Chessington, West Drayton, Maidstone, Aberdeen, Birmingham, Derby, Leeds, Northampton, Manchester, Swinton, Salford.

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.
