Thousands of parents who cared for young children in the 1980s and 1990s may have been shortchanged on their state pension — not through any fault of their own, but because HM Revenue and Customs failed to record their National Insurance numbers on Child Benefit claims. The result: missing credits that can mean hundreds of pounds less each year. HMRC and the Department for Work and Pensions have now launched a correction exercise, but research suggests many of those affected never came forward.
Women affected: thousands · Potential backpay: nearly £8,000 · Key periods: 1980s-1990s · Main issue: missing HRP credits · Source of alert: HMRC and DWP

Why don’t all pensioners get the new State Pension?
The UK state pension system underwent a significant overhaul in April 2016. Anyone reaching state pension age before that date falls under the old system, which included the Basic State Pension plus Additional State Pension. Those reaching pension age from 6 April 2016 onwards receive the new single-tier State Pension instead.
This distinction matters enormously for people who took time away from work to raise children. Under the old system, gaps in National Insurance contribution records could reduce the Basic State Pension. The Home Responsibilities Protection (HRP) scheme was designed to bridge those gaps for parents and carers.
Old vs new pension systems
The Basic State Pension required 44 qualifying years of National Insurance contributions or credits to receive the full amount. Each year of HRP reduced the number of qualifying years needed by one, up to a maximum of 20 years. The GOV.UK guidance confirms that HRP was automatically awarded if claiming Child Benefit for a child under 16 and providing a National Insurance number.
The new State Pension, by contrast, requires 35 qualifying years and operates differently. However, the transition exposed a long-standing problem: records showed that thousands of parents who claimed Child Benefit before 2000 never had their National Insurance numbers properly recorded, meaning HRP was never applied to their NI records.
Impact of HRP gaps
The DWP Research Report 1096 reveals that HMRC found National Insurance numbers were not always recorded on pre-2000 Child Benefit claims, preventing automatic HRP awards. DWP and HMRC subsequently launched the LEAP exercise to correct these missing credits and enable State Pension corrections with arrears.
Why are there two different state pensions?
The existence of two different state pensions reflects a gradual reform that took decades to implement. The old system developed piecemeal over the 20th century, combining a flat-rate Basic State Pension with earnings-related Additional State Pension. The 2016 reform simplified this into a single tier.
Basic vs new state pension
Under the Basic State Pension, workers needed 44 qualifying years for the full amount (£156.20 per week in 2024/25). Those with fewer years received a reduced amount proportional to their contributions. The LCP Partners analysis notes that each HRP year reduced the qualifying years needed for a full pension by one year, up to a maximum of 20 years.
The new State Pension, introduced on 6 April 2016, requires 35 qualifying years for the full amount (£221.20 per week in 2024/25). It replaced both the Basic and Additional State Pensions with a single, simpler structure. The GOV.UK confirms that National Insurance credits replaced HRP from 6 April 2010.
Qualifying years and HRP
HRP protected the NI records of parents by reducing the number of qualifying years required for the full Basic State Pension. It applied to anyone caring for a child under 16 who was receiving Child Benefit. GOV.UK also confirms HRP was available for Income Support claimants caring for sick or disabled persons between 1978 and 2010.
The pattern shows a clear administrative gap: post-2000 Child Benefit claims reliably linked NI numbers, while pre-2000 claims frequently did not, leaving a whole generation of parents with incomplete pension records.
Did my Child Benefit contribute towards my State Pension?
Yes — but indirectly, and only if the right records existed. Child Benefit claims did not directly fund your state pension. Instead, claiming Child Benefit for a child under 16 triggered an automatic award of Home Responsibilities Protection, which protected your NI record by reducing the qualifying years needed for the full Basic State Pension.
Link to HRP
The Low Incomes Tax Reform Group explains that HRP was automatically awarded if claiming Child Benefit for a child under 16 and providing a National Insurance number. Correcting HRP can increase weekly State Pension and provide arrears back to the eligibility date.
However, the DWP research found that National Insurance numbers were not always recorded on Child Benefit claims before 2000. DWP Research Report 1096 indicates that post-2000 Child Benefit claims more reliably linked National Insurance numbers for HRP purposes.
1980s-1990s claims
This means that parents who claimed Child Benefit in the 1980s and 1990s are particularly vulnerable to missing HRP credits. The LCP Partners analysis of a previous correction exercise identified 36,000 parents missing HRP, with £85m in arrears paid out and an average £10 per week increase in pension.
HMRC sent letters from December 2023 to September 2024 inviting potentially affected individuals to apply for HRP corrections, according to DWP research.
Parents who received Child Benefit in the 1980s and 1990s may have HRP gaps even if they never missed a payment. The error was on HMRC’s side, not theirs.
What is Home Responsibilities Protection?
Home Responsibilities Protection (HRP) was a scheme that helped protect the State Pension entitlements of parents and carers between 1978 and 2010. DWP’s official research describes it as a mechanism that reduced the number of qualifying years needed for the full Basic State Pension.
Eligibility criteria
HRP applied to individuals who were receiving Child Benefit for a child under 16, provided they had supplied their National Insurance number. It was also available for those claiming Income Support while caring for sick or disabled persons. The GOV.UK CF411 Notes clarify that HRP applications have no time limit for 1978-2002 periods, but the time limit has passed for 2002-2010 claims.
How it affects pension
Each year of HRP reduced the qualifying years needed for the full Basic State Pension by one year, up to a maximum of 20 years. LCP Partners notes that for pre-2010 pension age individuals, this could mean the difference between receiving the full pension or a reduced amount.
What this means: missing even a few years of HRP could reduce weekly pension by £10 or more, while backpay can reach nearly £8,000 depending on individual circumstances.
How do I check Home Responsibilities Protection eligibility?
The first step is to check your National Insurance record. The LCP Partners guidance recommends using GOV.UK’s State Pension tool to see whether any qualifying years are missing. This free checker shows your NI record and highlights any gaps.
Free checker tools
Visit the GOV.UK State Pension forecast page to see your current record. Look for gaps in the years when you were raising children. The GOV.UK HRP page provides official eligibility information and contact details.
If the checker shows gaps during periods when you were receiving Child Benefit, you may be entitled to HRP credits. The Low Incomes Tax Reform Group advises that correcting HRP can increase your weekly State Pension and provide arrears back to the eligibility date.
Claiming back payments
Contact HMRC to apply for an HRP correction. According to Evans Shaw, HRP claims typically complete in a few months, though complex cases involving name changes or split records may take longer. They recommend escalation at 2, 4, 8, and 12 weeks if no response is received.
Note that arrears payments for missing HRP are taxed similarly to previous State Pension underpayment exercises, according to the Low Incomes Tax Reform Group. This means an increased pension may lead to a larger tax liability on the arrears amount.

- Success rate of LEAP applications not yet published
- Regional variations in processing times
DWP research involving 40 interviews with non-applicants found that the majority of letter recipients did not apply due to scam fears, low engagement, and misunderstanding of the historic Child Benefit link. Participants were mostly women over State Pension age with low digital capability and high risk aversion. The research stated that “the level of risk aversion described by participants, paired with a lack of confidence in being able to accurately identify genuine communications from scams, was a major barrier with no clear solution.”

How to check your eligibility: Step by step
Three steps to determine if you’re affected and what to do next.
- Check your NI record online — Visit GOV.UK’s State Pension forecast page and review your qualifying years. Look for gaps during periods when you were raising children or receiving Child Benefit.
- Confirm HRP eligibility — If you claimed Child Benefit for children under 16 between 1978 and 2010, you should have received HRP. Missing gaps in your NI record during these periods warrant further investigation.
- Contact HMRC to apply — Call HMRC or use their online service to request an HRP correction. For claims relating to 1978-2002, there is no time limit. Provide evidence of your Child Benefit claims if available. Evans Shaw recommends escalating at 2, 4, 8, and 12 weeks if you receive no response.
Arrears from HRP corrections are taxable, and increased pension payments may push some recipients into higher tax bands or affect eligibility for Pension Credit. The Low Incomes Tax Reform Group advises checking with HMRC how backpay will be treated before submitting a claim.

Frequently asked questions
What is the 10 year rule for pension?
The “10-year rule” refers to the minimum number of qualifying years needed to receive any UK State Pension at all — even a reduced amount. Under the current new State Pension, you need at least 10 qualifying years to receive any pension. Under the old Basic State Pension, you needed fewer years for a reduced amount but 44 years for the full rate.
Can I claim both Irish and UK state pensions?
Yes, if you have contributed to both the Irish and UK state pension systems, you may be able to claim partial pensions from both countries. The exact rules depend on your contribution history in each jurisdiction and any reciprocal social security agreements in force.
Do I pay tax on my UK pension if I live in Ireland?
UK State Pension paid to residents of Ireland may be subject to UK tax rules, but the tax treatment depends on your residency status and any double taxation agreements between the UK and Ireland. Consult HMRC or a tax adviser for your specific circumstances.
How much was Child Benefit in 1980?
Child Benefit rates varied by the number and age of children. Exact rates from 1980 are historical and can be found in government archives. The important point for HRP eligibility is not the amount received, but the fact that a claim was made for a child under 16.
Is the UK State Pension the least generous in the G7?
International comparisons of state pension generosity vary depending on the metrics used. Some analyses rank the UK poorly on replacement rates (the percentage of pre-retirement income replaced by the state pension), but the picture is more complex when accounting for private pensions and other factors.
How much money can you have in the bank and still get a full pension?
The UK State Pension is not means-tested, so your savings do not affect your entitlement. However, the amount you receive may affect eligibility for means-tested benefits like Pension Credit, which has savings limits.
What are HRP back payments?
HRP back payments are arrears of State Pension that should have been paid if HRP credits had been correctly recorded. DWP recalculates your pension as if the correct HRP had been applied, and pays the difference back to when you first became eligible. According to LCP Partners, a previous exercise paid an average of £10 per week increase plus lump sum arrears.
Parents who claimed Child Benefit in the 1980s and 1990s and suspect they may be affected should check their NI record, confirm eligibility, and contact HMRC before processing delays accumulate. The correction exercise is active now, but unlike the older claim periods, it won’t stay open forever.
