Cooling and construction
The site covers liquid cooling, indirect air cooling and direct air cooling, and modular construction aimed at rapid deployment of dense infrastructure. Solutions pages run from enterprise colocation and cloud to hyperscale and high-power compute.
Scale figures and their age
The About page shows 567 MW secured compute capacity, 394 MW available, 27 data centres across 9 locations and a 59 percent reduction of Scope 1 emissions since 2019, each stamped as updated 1 January 2025.
Limitations to Consider
The scale figures on the website carry a January 2025 date, so ask for current numbers. Retail rack pricing and minimum unit sizes are not stated, and the offer leans towards public sector, built-to-suit and hyperscale buyers. The Brussels and Barcelona entries exist only as menu items on the pages checked. Ownership is not stated on the pages read, and pricing needs a conversation with sales.
Who Should Use Ark Data Centres
UK public sector bodies and cloud or compute tenants that value government-assured facilities and a range of cooling options.
