What is Home Responsibilities Protection and could I be owed backdated State Pension?
Home Responsibilities Protection (HRP) reduced the number of qualifying years needed for a full State Pension for parents and carers between 1978 and 2010, but a known administrative error means some people's HRP was never correctly recorded on their National Insurance record, potentially leaving them with a lower State Pension than they should have. HMRC and DWP have run a correction exercise, and it is worth checking your own record even if you have not been contacted directly.
Full answer
Home Responsibilities Protection was an older mechanism, in place before it was replaced by National Insurance credits from 2010, designed to protect the State Pension of parents and carers who could not build a full National Insurance record through paid work -- but a significant administrative gap means many people's entitlement was never correctly applied. **What HRP was designed to do** Between 1978 and 2010, HRP reduced the number of 'qualifying years' someone needed for a full basic State Pension, based on years spent at home caring for children (usually linked to receiving Child Benefit) or, in some circumstances, caring for a disabled person -- rather than adding qualifying years directly, HRP reduced the total number of years required, which had broadly the same practical effect of protecting the pension entitlement of full-time carers and parents. **The known administrative gap** Because HRP for parents was often linked to Child Benefit claims, and Child Benefit claim forms did not always require a National Insurance number to be provided (particularly in earlier years), some parents' HRP entitlement was never correctly recorded against their National Insurance record. This has been identified as a widespread issue, primarily but not exclusively affecting women who took time out of paid work to raise children between the late 1970s and 2010. **Why this can mean an underpaid State Pension** Where HRP was not correctly recorded, someone's National Insurance record may show fewer qualifying years than they were actually entitled to, potentially resulting in a lower State Pension than they should be receiving -- in some cases, for many years, since State Pension underpayments of this kind are not always identified quickly once someone has started receiving their pension. **The correction exercise** HMRC and DWP have run initiatives to identify and correct affected National Insurance records, including writing to some people identified as at risk from historic data, and providing an online tool to help people check whether they might be affected and, if so, make a claim to have their record corrected -- if your HRP was missed and your record corrected, any additional State Pension you are entitled to can be backdated, potentially resulting in a significant lump sum payment covering the period since you started claiming your pension. **Who is most likely to be affected** You are more likely to be affected if you claimed Child Benefit for a child born between 1978 and 2000 (particularly earlier in this period) without providing your National Insurance number on the claim form, and have since reached State Pension age or are approaching it -- though the specific circumstances that create a genuine gap can vary, and checking is worthwhile even if you are not certain you meet these exact criteria. **How to check** You can check your National Insurance record online through your personal tax account, and there is a specific online tool provided by HMRC to help identify whether you might have missing HRP -- if you believe you may be affected, you can submit a claim for HMRC to review and correct your record, which DWP will then use to recalculate your State Pension if appropriate. **Worked example** A woman who claimed Child Benefit for her children throughout the 1980s and 1990s, but whose claim did not include her National Insurance number, discovers gaps in her National Insurance record for years she was actually protected by HRP. She uses the online checking tool, submits a claim, and HMRC corrects her record to reflect the missing HRP years. DWP recalculates her State Pension, finding she has been underpaid for several years since she started claiming, and she receives a backdated lump sum alongside an increase to her ongoing weekly payment. **Practical tip** Even if you have not been contacted directly as part of the correction exercise, if you claimed Child Benefit at any point between 1978 and 2010 without providing your National Insurance number, it is worth checking your record using HMRC's online tool, since this is a case where being proactive, rather than waiting to be contacted, could uncover a genuine underpayment going back many years.
