In the third quarter of 2014 the proportion of interims in the public sector compared to the private sector increased from 40% to 49%. This represents the most widespread use of interims in the public sector since 2009.
Around four in 10 (41%) of the interim managers in the public sector are found in local government, with 17% in central government and 15% in education.
Within the private sector the financial sector still has by far the highest use of interim managers. Almost half (46%) can be found within the industry.
The proportion of female interim managers remains steady at 35%, largely unmoved across the past 12 months.
Green Park senior partner Neil Lupin, who specialises in local government interim management, said the expected cuts in public services from 2015 to 2020 require a "fundamental rethink" about the way services are delivered.
"Demand for interims to lead these changes is as high as it has ever been and hasn’t peaked," he added.
"New skills are needed, for example in commercialising services and customer services channel shifts. In traditional areas such as children’s services, the demand for turnaround assistant directors and directors far outstrips supply.”
