Yondr Group: London campus

London campus is the name Yondr Group uses for its hyperscale data center campus located in Slough, West London, described by Yondr as a three–data center campus planned at 100MW+ total capacity.

Yondr’s official website (yondrgroup.com) publishes multiple facility milestone announcements for the London campus (Slough), including ready-for-service and construction updates for the first, second, and third buildings. Yondr does not publish a single campus page that discloses a facility street address or full technical specification sheet.

Third-party reporting places the campus on redeveloped industrial land in Slough (including references to the former Uxbridge Road Gas Works and a disused Akzo Nobel paint factory), but precise site addressing for the “London campus” in operator materials is Not publicly disclosed.
