CorScale Iver (Court Lane)

CorScale / Affinius Capital · approved · Buckinghamshire Council

Hyperscale campus on Court Lane Industrial Estate, Iver (between Slough and Hayes on the M25 fringe). Outline consent for up to 65,000 m² GEA across two data centre buildings. SoS recovered appeal allowed 6 December 2024. The decision documents describe a 103 MW scheme with 90 MW of IT load and 140 MVA reserved from the planned Uxbridge Moor substation; trade reporting rounds this up to 140 MW.
