The efficiency target set for the police service in the spending review 2004, taking into account the Gershon review, was for the 43 police authorities and forces in England and Wales to deliver aggregate value for money gains of 3 per cent. of net revenue expenditure per annum. Half of the total gains were required to be cashable, and forces and authorities were expected to achieve cumulative total gains of £1,060 million (£518 million cashable) over the four years 2004-05 to 2007-08.
As of April 2007 these targets have been achieved by the police service and are set out in the Home Office targets autumn performance report 2007 which is available in the Library of the House.
