# London Data Center Market Analysis
London's colocation market is severely constrained by power availability despite moderate physical capacity. The tracked estate spans 415 facilities totaling 916 MW across five dominant operators, yet the DCPI excess-power score of 16/100 signals acute scarcity in available power allocation, while the constraint rating of 77/100 indicates structural grid and real-estate bottlenecks that will not resolve near-term. Digital Realty holds the largest footprint at 20 facilities, followed by Equinix (17), DataBank (16), Telehouse (11), and a significant Unknown operator portfolio (13 sites), fragmenting operator leverage and complicating bulk expansion.
For acquisition-focused investors, the DCPI verdict is unambiguous: AVOID. The 77/100 constraint score eliminates the operational flexibility required to justify M&A at current valuations. Buyers pursuing London capacity will face structural power rationing, extended grid interconnection timelines, and planning friction in both West London and emerging East London submarkets. The excess-power deficit of 16/100 means even acquired facilities will struggle to deliver committed MW to customers, eroding the core IRR thesis. Capital deployed here encounters regulatory and infrastructure drag without compensating topline growth optionality.
Recent M&A confirms operator caution and selective deployment. Stack Infrastructure's sale to Nvidia (September 2026) and Google's four recent transactions (June 2026) suggest hyperscaler-led acquisitions targeting specific use cases rather than broad capacity plays. Digital Realty's $200M Slough acquisition in July 2024 represents the largest tracked deal, demonstrating that tier-one operators are still active but are prioritizing West London submarkets with existing grid headroom and planning certainty. DataBank, Kao Data, and Arcus (Portus owner) are pursuing brownfield and edge-market strategies—smaller sites and industrial conversion—to sidestep central London congestion. This bifurcation indicates that only operators with sufficient capital and planning relationships can navigate the market; pure-play acquisition funds face execution risk.
Planned supply introduces longer-dated complexity: a 64MW West London development and a 180MW East London project in Charlton both have planning approval or filed proposals, but neither is operational, and power availability for these sites remains uncertain. The East London 180MW project, in particular, signals developer confidence in decentralized growth, yet execution timelines remain unannounced. London investors should monitor grid reinforcement schedules and Q4 2026 planning decisions; without demonstrable power allocation to new sites, the AVOID verdict will persist through 2027.
