The Department for Work and Pensions (DWP) has been urged by MPs to issue compensation payments to as many as 800,000 state pensioners following a major error in the government's online pension forecasting system. The cross-party Work and Pensions Committee published a report on Saturday revealing that the calculator, launched in February 2016, provided inflated retirement income estimates for almost a decade.
Error in the Forecasting System
The online tool, designed to help Britons estimate their state pension and determine whether they need to make additional National Insurance contributions, failed to account for “contracting out” arrangements. These arrangements allowed workers to pay reduced National Insurance in exchange for enhanced private pensions. As a result, some users were incorrectly told they would receive the full state pension, with forecasts overstated by as much as £100 per week.
The DWP first became aware of the fault in 2017, but corrections were not implemented until 2021—four years later. According to The Telegraph, whose investigation uncovered the issue, around 360,000 people had already received inaccurate forecasts by the time corrections were made, and up to 800,000 could have been affected overall.
Impact on Pensioners
Baroness Altmann, a former pensions minister, warned that relying on the calculator could lead to poor financial decisions. Andrew Tully, technical services director at Nucleus Financial, added that individuals may have made damaging choices based on the incorrect forecasts. The committee’s report emphasized that ministers only acted after The Telegraph’s report, despite the issue persisting for nine years.
The DWP confirmed that the online issue has been resolved and stated it welcomes the committee’s report, pledging to respond to its recommendations. The call for compensation now puts pressure on the government to address the financial harm caused to hundreds of thousands of pensioners.
