Hundreds of thousands of British pensioners may be walking around with a silent shortfall in their bank accounts — money they earned, money they’re owed, but money they’re simply not receiving. And according to some of the country’s most experienced pensions experts, the problem hasn’t gone away.
More than half a million people on the State Pension are believed to be underpaid. That’s roughly one in 20 retirees. For some, the losses stretch into the tens of thousands of pounds over a typical retirement that can easily span two decades.
This isn’t a rounding error. It’s a systemic issue.
The Scale of the Problem
The Department for Work and Pensions (DWP) has been correcting historic State Pension errors since 2021. Yet even after years of reviews, officials still report that around 5% of claims contain mistakes.
Sir Steve Webb — former Pensions Minister and now a partner at consultancy LCP — has issued a stark warning.
“We have almost reached the stage where people should start from the assumption that their pension may be wrong,” he said, urging retirees to actively check their records rather than assume the system got it right.
Let that sink in. A former minister is effectively telling pensioners to double-check the government’s maths.
The DWP first admitted in 2021 that historic calculation errors had left an estimated 200,000 elderly women underpaid. The correction bill has since ballooned to around £800 million in arrears.

Who Has Been Hit the Hardest?
The underpayments have not been evenly spread. Three groups of women were particularly affected:
| Group Affected | What Went Wrong | Potential Impact |
|---|---|---|
| Widows | Inherited pension uplift not applied after husband’s death | Thousands lost over retirement |
| Married women | Pension not reassessed based on spouse’s National Insurance record | Ongoing weekly underpayments |
| Women over 80 | Not automatically uplifted to correct minimum amount | Lower pension than legally entitled |
In some cases, women over 80 were receiving less than £110.75 per week when their pensions should have been reassessed and increased.
Baroness Altmann, another former pensions minister, didn’t mince words: underpaying one in 20 older women means hundreds of thousands are living on less than they should.
And when you’re on a fixed income, every pound matters.
The Hidden Childcare Credit Problem
There’s another layer — one that stretches back decades.
Between 1978 and 2010, parents who left work to raise children were entitled to Home Responsibilities Protection (HRP). This reduced the number of qualifying National Insurance years needed for a full basic State Pension.
For example, someone who spent 19 years caring for children wouldn’t need the full 39 qualifying years — they would only need 20.
In theory, that protection should have safeguarded pensions for stay-at-home parents. In practice, many childcare periods were never correctly recorded on National Insurance files.
That means credits weren’t applied. And if credits weren’t applied, pensions were calculated too low.
Sir Steve Webb has openly questioned why, given the long-standing knowledge of HRP issues, the DWP did not build clearer questions about children into the State Pension claim process.
It’s a fair question. Especially when the error was known for years.

Why This Matters Now
Retirement isn’t cheap. Energy bills fluctuate. Food prices haven’t exactly rolled back to 2019 levels. Council tax keeps creeping up.
Morgan Vine of Independent Age says many older people are already making “drastic cutbacks on essentials such as food and water.”
Now imagine doing that while unknowingly missing money you were legally entitled to.
Even a £20 weekly shortfall amounts to over £1,000 a year. Stretch that over 20 years and you’re talking £20,000 — without accounting for annual uprating under the Triple Lock.
Small bureaucratic errors compound over time. That’s the real sting.
How to Check If You’re Being Underpaid
Experts say pensioners shouldn’t panic — but they should verify.
Here’s what to review:
• Your State Pension award letter
• Your National Insurance contribution record
• Whether you received Home Responsibilities Protection (if you cared for children pre-2010)
• Whether your pension was reassessed after widowhood
• Whether you’re over 80 and receiving the correct minimum
You can request a pension statement or forecast directly from the government via https://www.gov.uk/state-pension-statement.
If you believe there’s an error, you can contact the Pension Service through the DWP’s official contact page at https://www.gov.uk/contact-pension-service.
Importantly, back payments have been made in many cases once errors were identified — sometimes worth thousands of pounds in lump sums.
But corrections generally happen only after cases are reviewed. And reviews don’t always begin unless questions are asked.
A Bureaucracy Under Pressure
To be fair, the State Pension system is vast. It handles millions of records, some stretching back half a century, many originally paper-based.
But as Sir Steve Webb put it, while the numbers may be small for a “giant bureaucracy,” they are life-changing for individuals.
That’s the uncomfortable truth. For Whitehall, it’s a percentage. For pensioners, it’s heating, groceries, independence.
And after four years of correction exercises, the fact that 5% of claims are reportedly still wrong raises legitimate concerns about process oversight.
The DWP has said it is committed to correcting errors and paying arrears where due. Yet experts argue the responsibility increasingly falls on individuals to verify their own entitlements.
It shouldn’t be that way. But for now, it is.
If you’re receiving the State Pension — or about to claim it — don’t assume everything is accurate.
Check your National Insurance record. Confirm childcare credits. Review whether life events such as marriage or bereavement triggered a reassessment.
Because while the system is slowly correcting historic mistakes, time matters. Every year an underpayment goes unnoticed is another year of lost income.
Retirement should be about security, not forensic accounting. But until confidence in the system is fully restored, a little scrutiny could make a very big difference.
And in today’s cost-of-living climate, no pensioner can afford to leave money on the table.
