Question to the Department for Work and Pensions:

To ask His Majesty's Government what (1) proportion, and (2) number of (a) male, and (b) female, retirees do not receive the full pre-2016 and post-2016 state pension.

During 2019, a new DWP computer system called “Get Your State Pension” (GYSP) came online to handle State Pension claims. The GYSP system is now handling a sizeable proportion of new claims.

The department has not yet been able to include GYSP system data in our published statistics for State Pension and the number of GYSP cases are too high to allow us to continue to publish State Pension data on Stat-Xplore. We have been providing GYSP estimates based on payment systems data and as a temporary measure, State Pension statistics are being published via data tables only. The latest release in August 2023 contains State Pensions estimates for the quarters to February 2023.

A biannual release of supplementary tables to show State Pension deferment increments and proportions of beneficiaries receiving a full amount was suspended. This release is normally based on a 5 per cent sample of the legacy computer system. Given the absence of GYSP data, the figures are affected by the same issues as described above. The latest available time period for these figures is for September 2020 and can be found in the DWP benefits statistics published in May 2021 on gov.uk.

We are developing new statistical datasets to properly represent both computer systems. Once we have quality assured the new data it will be published on Stat-Xplore, including a refresh of historical data using the best data available.

For more information on these developments, see the State Pension section of the ‘Background information note: DWP benefits statistical summary’ published on gov.uk.
