DWP Confirms £230 Underpayment Risk for Half of State Pensioners

More than 230,000 pensioners in the UK—primarily women—may have been short-changed on their state pension due to systemic administrative errors within the Department for Work and Pensions (DWP). With an estimated £835 million owed, this scandal is one of the most significant oversights in UK pension history, sparking widespread concern and calls for reform.

Who Was Affected by the Underpayment?

According to the DWP, approximately 237,000 pensioners were underpaid, mostly under the older state pension system that existed prior to April 6, 2016. This system often required manual updates for certain benefits, such as:

• Married women whose pensions were supposed to increase when their husbands retired
• Widows entitled to a portion of their late spouse’s pension
• Divorced women due additional payments based on their ex-spouse’s contributions
• Over-80s eligible for automatic pension boosts

Unfortunately, due to missed updates and a lack of automated systems, these uplifts were never applied in many cases.

Breakdown of the Underpayments

The financial impact is staggering. Here’s a breakdown of the total estimated underpayment and how much has been repaid:

Group Affected	Estimated Repayment
Total Pensioners Affected	237,000
Total Owed in Arrears	£835 million
Amount Repaid (as of 2025)	£571 million
Pensioners Reimbursed	150,000+

Some individuals have received back payments exceeding £40,000, with the arrears stretching back decades.

How Did This Happen?

The core issue lies in how the old pension system relied heavily on manual intervention. Key life events—such as a spouse reaching pension age or passing away—were meant to trigger benefit increases. But because these changes weren’t always flagged or updated in the system, many pensioners continued receiving lower payments indefinitely.

This breakdown disproportionately affected women, particularly those who stayed at home to raise children or care for family members, and who therefore had fewer qualifying National Insurance contributions. While the system offered spousal or survivor entitlements to address this, the failure to process them properly meant many missed out.

What Is Being Done?

The DWP began a correction exercise in January 2021 to identify and fix underpayments. So far:

• Over 150,000 pensioners have been reimbursed.
• £571 million has been paid out.
• The DWP aims to complete the review over the next couple of years.

The department has said no action is required from individuals to be included in the review. However, being proactive may still help, especially if you or a loved one believes you’re eligible.

What Can Affected Individuals Do?

If you think you or a deceased family member may have been underpaid:

• Contact the DWP’s Pension Service to inquire about a review.
• Keep relevant documents, such as letters, pension statements, or National Insurance records.
• Executors can also claim on behalf of deceased pensioners’ estates.

Political and Public Backlash

Former pensions minister Sir Steve Webb, now a partner at consultancy LCP, described the situation as one of the “biggest blunders in state pension history.” MPs and campaigners have since demanded:

• Greater transparency from the DWP
• A shift to automated systems to prevent manual errors
• A public apology and faster compensation

With trust in the DWP shaken, many are calling for urgent modernization of the pension infrastructure.

A Wake-Up Call for Reform

This scandal underscores the urgent need for systemic reform in the UK’s pension administration. As the population ages and more people rely on state benefits in retirement, accurate and timely payments are essential. Ensuring automation, cross-checking life events, and reducing manual workloads could prevent similar failures in the future.

In the meantime, pensioners and their families should stay vigilant. If there’s any doubt about pension entitlement, it’s worth checking.
