The Mayor of London Sadiq Khan last week pledged "coordinated action" to deal with the impacts of growing data center demand in London.
Chief among these concerns is the “increasing connection queue” for data center power in London.

London currently delivers around 1GW of data center capacity at peak demand, but demand for power in the grid connection queue reaches ten times that existing amount, according to a December 2025 report commissioned by the Greater London Authority and prepared by British engineering consultancy firm Buro Happold.
The project also identified 99 operational data centers in Greater London.
