Background

Over a decade ago, public sector pension schemes were reformed building on the findings of the Independent Public Service Pensions Commission, chaired by Lord Hutton. The Commission conducted a fundamental structural review of public service pension provision.

The Coalition Government accepted the recommendations of the Commission’s final report as the basis for negotiation with the trade unions and legislated in the Public Service Pensions Act 2013 for a framework for new public service pension schemes that were introduced from April 2015.

Key changes for the reformed schemes were moving from a final salary to a career average basis and linking the Normal Pension Age in the scheme to State Pension Age. In the course of negotiations on the reforms, the then Chief Secretary to the Treasury, Danny Alexander, said that the reformed schemes should endure for 25 years.

The need to control future spending

It was also agreed that there should be a mechanism to control future spending on public service pensions, by setting a fixed proportion of pensionable pay that public service employers would contribute to the schemes in the long term. If this cost were exceeded (or fell beyond certain minimum parameters), then the Government should consult on how to bring those costs back within the agreed parameters, with an automatic default to be applied if agreement could not be reached.

To achieve this, the government established cost control mechanisms which calculate the cost of providing scheme benefits. This mechanism is generally applied to those benefits that have been accrued since the career average reforms took effect in April 2014.

The cost control processes

In LGPS there are two processes that run alongside each other to deliver this aim.

The first is a HMT-led process that was originally designed only to control changes in “member costs” (those relating to assumptions about the profile of scheme members) and excluded changes in “employer costs” (those relating to assumptions that are financial or technical in nature). However, following a consultation in 2021, the Government introduced a further check to link this process to changes in the long-term economic outlook. This meant that there would be a higher bar for benefit increases to be awarded if the country’s long-term economic outlook worsened.

The LGPS Regulations 2013 state that the employer cost cap for the Scheme under this process is 14.6% of pensionable earnings (excluding member contributions). Actuarial assumptions to allow the calculation of this are set out in HM Treasury Directions.

One of the Board’s statutory duties, under the 2013 regulations, is to introduce and maintain its own process to examine costs in the scheme alongside the process introduced by HM Treasury. The aim of this process is to provide greater control over employer contribution rates and the actuarial assumptions for this are decided by the SAB. The 2013 Regulations set the agreed target future service rate for the LGPS in England and Wales, at 19.5% of payroll (including member contributions).
