Google · operating · Broxbourne Borough Council

Google's first owned-and-operated UK data centre, on the former Maxwell's Farm off the A10 Great Cambridge Road, about one mile from M25 J25. Opened September 2025 on a 33-acre site as part of a two-year £5bn UK investment (about $1bn for this facility). Air-cooled, limiting water to domestic use, with off-site heat-recovery provisions. Google does not publicly disclose a megawatt figure. Mapped as operating from operator or third-party records; no council planning-application URL is linked.
