These savings included include £3.4 billion by reducing the size of the Civil Service and reforming Civil Service pensions; £3.8 billion by linking together departments to buy goods and services and enforcing controls on recruitment and use of consultants; and £0.6 billion by exiting 500,000 square metres of property. In December 2014 Francis Maude set out plans to make a further £10 billion of efficiency savings between 2017 and 2018 and an additional £15 to £20 billion for 2019 to 2020.
