Pension back payments—up to £12,000:
In the UK, thousands of people who have been looking forward to their retirement earnings are subsequently getting them. As a result of the Department for Work and Pensions’ (DWP) preceding errors, over one hundred thirty thousand pensioners have already acquired over £800 million in pension back payments. Many humans aren’t aware that they will also be eligible for this essential economic advantage, but some are receiving lower back payments of as much as £12,000.
Since January 2021, the DWP has embarked on a massive reform process to rectify historical errors in the payment of pensions. As per the latest update released in April 2025, £804.7 million in payments has been made to 130,948 individuals whose pension payment was in arrears between January 2021 and March 2025.
Up to £12,000 in pension back payments

These deficiencies were primarily the result of administrative errors, the majority of which were women whose pensions were not correctly paid for years, not decades.
Vital update: Between January and September 2024, a distinct correction process identified 5,344 pension deficiencies, £42 million of which was backpaid.
Who are pension back payments affecting?
These payments primarily impact three primary groups:
- Married women with a reduced state pension:
- Most women who were married should have been automatically upgraded to a higher pension when their husband retired, yet this was never done.
- Widows:
- A few people’s pensions had not been properly recalculated when their husband passed away, and now they have a smaller pension for a longer number of years.
- People over 80:
- Some people were not given their basic state pension when they reached 80 years old, which they were entitled to start at this age.
Average value of pension back payments:
The DWP has published how much the average payments were in various categories:
- Married women (Category BL): £5,553
- Windows: £11,725
- Individuals aged 80 and over (Category D): £2,203
Note: Some cases were looked into under more than one category, as they could have been caused by more than one error.
Home Responsibility Protection (HRP) Correction Process
Apart from the overall pension reform, the DWP is also operating a standalone project to rectify missing payments under Home Responsibility Protection (HRP). The HRP was designed to safeguard the pension entitlement of parents and carers, but most records were incomplete as a result of administrative errors.
Between January and September 2024, 5,344 HRP-related shortfalls in pensions were identified, and a total of £42 million was discovered.
How to find out if you are eligible for pension back payments?
DWP will contact some people.
The DWP has stated that they will contact some people, especially married women, whose back payments have been discovered during their internal checks. But if you are widowed or aged over 80, do not wait for the DWP to get in touch with you. Check your eligibility now.

Expert reaction to pension underpayment scandal
Former pensions minister and LCP partner Sir Steve Webb condemned the scale of these errors. He stated:
“Most of those affected were women, some of whom were underpaid for decades or never paid the proper pension. The rest need to be sorted out as a matter of urgency. This should never happen again.”
DWP response and ongoing action
A DWP official recently stated:
“Our focus is on making sure pensioners are treated with respect and protected in retirement and to reduce mistakes in the payment of state pensions. We have resolved most cases in this correction process, and in a limited number of cases, further documentation is needed from the customer.”
The DWP has also implemented various administrative changes in order to cut down the level of error so that such an error is never repeated in the future.
Why are women more affected?

The UK’s state pension system has historically been based upon a male-breadwinner family model, in which a high number of women depended on their husband’s National Insurance record to establish their right to a pension. Systematic bias and administrative mistakes within the system meant that a high number of women failed to receive their full pension on time.
While there have been improvements, mistakes in the original system still affect pensions in the 2020s, predominantly the older generation of women.
The monetary effect of getting back payments
Getting £5,000, £10,000, or even £12,000 can totally revolutionize a pensioner’s financial situation.
- Wiping out debt: Most pensioners utilize their back payments to clear outstanding debt or credit.
- Home improvements: Necessary repairs or enhancements are finally achievable.
- Enhancing savings: added security for future costs.
- Enhancing standard of living: Enjoy financial freedom in retirement.
Hence, it is highly crucial for entitled persons to make their claim.
If you are a married woman, a widow, or aged 80 or more, it is crucial that you verify if you are due back payments of pension. The mean payment can be in thousands of pounds, and you must not miss out on availing yourself of this.
The DWP is working on cases actively, but you can make your claim process faster using resources like the LCP calculator and calling the Pension Service. Since historical injustices are being corrected, it is important that pensioners and their families remain informed and take necessary action to claim their rights.
