4.6 The government agrees with the Committee’s recommendation. Target implementation date: June 2026 ... 4.11 The coalition government introduced new public service schemes from 2014 to 2015. The main changes were to increase the scheme normal retirement ages to the state pension age (except for the police, firefighters, and the armed forces who have a normal retirement age of 60), increase member contributions, and move from a final salary to a career average design. Separately, the indexation of public service pensions was changed from RPI to CPI. 4.12 The government also maintains the Cost Control Mechanism, which provides for automatic adjustments to scheme design if certain costs move outside of a set corridor. 4.13 The government’s preferred measure of the cost of the schemes remains the OBR’s long-term projection of spending on pension benefits as a share of GDP, rather than the figure of accrued liabilities, including due to the difficulties in interpreting the liability figure previously noted by the PAC.
