Ark Data Centres (UK): Spring Park 1

Ark Spring Park (P1 building) is part of the larger Ark Spring Park data centre campus located in Corsham, Wiltshire, UK.  The Spring Park campus comprises multiple data centre buildings (SQ17, P1, P2, P3, P4, P5) and is designed to offer scalable, high-security, low-PUE infrastructure. Corsham’s location in Wiltshire, near the M4 corridor and in proximity to London, offers strategic connectivity advantages and access to regional fiber backbones. With modular scalability and emphasis on efficiency and security, Spring Park positions itself as a wholesale data centre campus supporting high-demand, mission-critical workloads.

⚙️ Facility Highlights

• Spring Park campus total planned IT load capacity: 46 MW 
• Net technical space across campus: ~ 200,000 sq ft 
• Modular design in buildings P1–P3: each building contains 6 data rooms (halls), each hall ~760 kW capacity (approx. 182 cabinets at 4.2 kW per cabinet) 
• Design PUE (Power Usage Effectiveness): 1.2 (i.e., for each 1 MW IT load, ~200 kW cooling & overhead) 
• Campus power feeds: multiple 33 kV sources; for first buildings, two 33 kV feeds delivering ~40 MVA; additional feeds support P3 / P4 at ~48 MVA 
• Security-oriented location: adjacent to MOD (Ministry of Defence) Corsham, supporting the high-security profile of the campus 
• Diverse carrier access: the Spring Park campus is listed on PeeringDB with multiple fiber providers (16 carriers) and multiple distinct fiber entry paths 

🔐 Security & Compliance

• Highly secure campus with multiple buildings under strong perimeter control, designed for wholesale data centre use cases 
• Proximity to MOD Corsham adds a security context and co-location with government/defense services in the area
• Access controls, surveillance, and physical security are core design principles of the campus (though specific systems in P1 are not publicly disclosed) 
• Compliance and certifications: The Spring Park data centre listing indicates support for major standards such as ISO 27001, ISO 22301, ISO 9001, ISO 14001, ISO 50001, ISO 45001 and Cyber Essentials Plus, as listed in Ark’s locations page. 

🌐 Connectivity & Carrier Access

• Carrier-neutral campus enabling connectivity flexibility for tenants 
• Diverse fiber entry and multiple carriers: the campus supports 16 distinct fiber providers and multiple fiber paths per building 
• Proximity to major fiber corridors via the M4 / western England networks enables low-latency access across the UK and to London hubs 
• On-campus interconnect and cross-connect capabilities among buildings, leveraging the modular campus framework 

💼 Who It Serves

• Wholesale / hyperscale cloud and enterprise operators looking for large contiguous power and space in the UK
• Carriers, network operators, and IX / peering providers seeking robust interconnection hubs outside London
• Government, defense, and regulated sectors requiring high-security infrastructure near MOD facilities
• High-performance workloads, AI/ML rigs, HPC, and data-intensive applications benefiting from low PUE and modular scalability
• Organizations preferencing campus-style expansion, redundancy, and flexibility over monolithic data center builds
