The "MW, all listings" tile above is a wider measure (every tracked site that reports MW, any status, unverified directory listings included), so it is larger than Total listed.
Broker lease rates (CBRE/JLL): available on paid plans. Asking base rent per kW of critical IT capacity. Electricity is normally billed separately (metered pass-through), plus cross-connects and one-time fees. Signed deals, term and size change the number.

The market continues to attract development interest, with recent planning approvals including a 50,000 sqm facility in West London designated for 64 MW of electrical draw and 48 MW of IT load, and a 180 MW development proposal filed for an East London brownfield site in Charlton. Telehouse acquired a Docklands office campus with plans for a 65 MW data center adjacent to its existing London operation.
This combination indicates that grid access and power availability represent material blockers for greenfield or expanded build-out, not demand or market quality concerns. New entrants and capacity expansions should expect protracted grid connection timelines and potential need for alternative power sourcing strategies.
Recent deal flow reflects consolidation and site assembly rather than wholesale capacity transactions. Arcus executed three acquisitions with Volta on consecutive dates in early July 2026, followed by an acquisition from Verne on 9 July 2026, indicating rapid portfolio consolidation in the region. Separately, Blackstone entered a lease arrangement with an unspecified counterparty on 21 October 2026.
