PCI DSS data centers in United Kingdom

Facilities in United Kingdom that publish PCI DSS certification. Mandatory for infrastructure that stores, processes or transmits cardholder data. Without it, payment workloads cannot legally land in the facility.

34 of the 196 facilities we track in United Kingdom publish PCI DSS — 8 operators, 72 MW of published IT capacity, 34 operational. Cities: London, Reading, Havant, Corsham, Farnborough, Slough, Woking, Crawley, Chessington, West Drayton, Manchester, Swinton.

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.
