To ask the Chancellor of the Exchequer what percentage of his Department's computer systems use open source software; what percentage of the systems planned to be installed use such software; and whether he plans to increase the use of open source software in his Department. (111156)

Less than 1 per cent. of HM Treasury's desktop and laptop PCs use open source software. 6 per cent. of the Department's servers use open source software. The use of open source software is less than 1 per cent. in planned computer systems.

HM Treasury follows the Government's published policy, considering open source solutions alongside proprietary ones in IT procurements, and awarding contracts on a value for money basis. The policy can be viewed at the UK Govtalk website.
