Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what is the annual cost to the public purse of her Department's expenditure on (a) IT infrastructure, (b) IT infrastructure purchased prior to 2013 and (c) legacy IT infrastructure for each year since 2010.

The accounting systems track IT spend, but do not capture the level of detail readily to identify spend on Infrastructure or legacy systems. Determination of legacy IT will require more work; the Legacy Risk Assessment will be prepared and submitted to Cabinet by the end of the current Financial year. Currently, within our centrally managed digital function, there is no legacy IT of any material size or value.
