Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what estimate they have made of the total annual estate and electricity cost of housing digital infrastructure and IT systems, legacy and otherwise, across the server rooms of the government estate.

There is currently no centrally conducted analysis of the total estate and electricity cost across for housing digital infrastructure or IT systems. HMT provides guidance for how to estimate the cost of both land and energy consumption when a business case is being developed. This helps to ensure that the best value for money option is selected when a new project is undertaken. For digital projects the Government Cloud First policy states that when procuring new or existing services, public sector organisations should default to Public Cloud first and where there is no choice but to host on-premises, use Crown Hosting.
