Our response 

  • Questions 1 and 2

The information requested is not currently held. The GLA is in the process of developing a new Data Centre Monitoring Dashboard which is intended to provide information on planning applications for existing data centres in London, as well as applications awaiting determination and those with consent awaiting completion. The dashboard is subject to an ongoing programme of data collection, verification and quality assurance, a process which has already taken several months and is expected be completed in the coming months. In the meantime, any information that the GLA receives regarding data centre planning applications can be found on the Planning London Datahub.
