Vantage CWL1 Cardiff Campus

A private 400kV SuperGrid connection sets the Cardiff campus apart from most UK colocation sites: Vantage's CWL1 draws grid power directly rather than through local distribution, supporting 148MW of critical IT load. The 46-acre site at Celtic Way near Newport, South Wales, spans roughly 2,000,000 gross sq ft (186,000 sqm) across three planned data centers, two of which are operational. Rack densities run from standard 2kW deployments up to 125kW and beyond, served by a mix of indirect evaporative air handling, dry cooler CRAH systems and pumped DX, with customized HPC cooling available and minimum N+1 redundancy on mechanical plant. The campus runs on 100% renewable energy and holds ISO 9001, 14001, 27001 and 45001 certifications alongside ISAE 3402 and SOC 2 attestations, built to Tier III standards. Wales-to-London latency under 1.5ms, 12+ international carriers and LINX Wales hosting make it viable for hyperscalers and AI operators seeking large contiguous capacity outside the constrained London market.
