Frequently Asked Questions

Why is colocation in London the largest in Europe?
London hosts LINX (one of the world's largest internet exchanges), is Europe's financial capital, and lands transatlantic submarine cables. 274 facilities operated by 110 providers — Equinix, Digital Realty and NTT alone exceed 45% of installed MW.
Slough or Docklands — which?
Slough wins for financial trading (Equinix LD4-LD9, sub-59ms to NYC, larger floor plates, cheaper power). Docklands wins for interconnection density (LINX, Telehouse, highest carrier diversity in UK). Royal Docks emerging for AI.
Is London expensive?
Yes — among the most expensive European markets. Premium rack rates in Slough/Docklands financial corridors. Royal Docks and outer-London builds offer 30-40% lower per-kW pricing for AI/enterprise workloads where premium interconnection isn't critical.
What's coming in the next 24 months?
1.6 GW of upcoming UK capacity led by Digital Reef, Equinix, Ada Infrastructure and Tritax Big Box. Telehouse West Two (£275m) is the most prominent under-construction project in central London.
