Grandparent Childcare National Insurance Credits 2026/27: The Specified Adult Childcare Credit Explained
Grandparents who look after grandchildren while the parents work can claim National Insurance credits worth a full qualifying year towards State Pension — a widely underclaimed entitlement. Full guide to eligibility, backdating and how to apply.
The most underclaimed pension entitlement in the UK
Millions of grandparents provide regular, unpaid childcare so their adult children can work — but relatively few know that this care can be converted into a National Insurance credit worth a full qualifying year towards the State Pension. Given that each qualifying year is worth roughly £359 a year for the rest of your retirement, and claims can be backdated over a decade, this is genuinely one of the highest-value, most overlooked pieces of the UK benefits and pensions system.

When a parent claims Child Benefit for a child under 12, they automatically receive a National Insurance credit for that tax year (Class 3, providing a qualifying year towards their State Pension) — this is designed to protect the pension of a parent who has taken time out of paid work to raise children.
But many working parents already have a full qualifying year from their own employment (their salary is above the Lower Earnings Limit, so they're already accruing NI through work). In that situation, the automatic Child Benefit NI credit sits unused — the parent doesn't need it because their job already provides the qualifying year.
The Specified Adult Childcare credit lets that unused credit be transferred to a family member — most commonly a grandparent — who provided the actual childcare that allowed the parent to work, giving the carer a full qualifying year towards their own State Pension, at no cost to the parent.
Worked example: grandmother caring two days a week
Scenario: a grandmother, aged 62 (below State Pension age of 66), looks after her granddaughter two days a week so her daughter can work full-time. The daughter claims Child Benefit and is already accruing a full NI qualifying year through her own job, so the automatic Child Benefit credit is unused.
The grandmother has a gap year in her NI record from an earlier career break and is short of the 35 qualifying years needed for a full State Pension.
By claiming the Specified Adult Childcare credit for each tax year she provided this care, she can add qualifying years directly to her own record — potentially closing the gap entirely if she claims for several years of care, backdated to when she started.
Value of one additional qualifying year: roughly 1/35th of the full new State Pension (£241.30/week in 2026/27) = approximately £6.90/week, or £358.80/year, paid for the rest of her retirement. Over a 20-year retirement, that's worth over £7,000 from a single qualifying year — for childcare she was providing anyway.
If she backdates a claim covering, say, 5 years of care (2019/20 through 2023/24), she could add 5 qualifying years at once, worth roughly £1,795/year (5 × £358.80) on top of her State Pension for life — a transformative difference for someone who was short of the 35-year threshold.
Eligibility conditions
- The child must have been under 12 throughout the period claimed (under 17 if disabled)
- The parent must have been entitled to Child Benefit for that child and tax year
- The parent must have their own qualifying year already secured (through employment, self-employment, or other NI credits) for the years claimed, so the automatic credit is genuinely unused and available to transfer
- The carer must be aged 16 or over and under State Pension age at the time the care was provided
- The care must be a genuine, regular childcare arrangement, not one-off babysitting
How and when to apply
Applications use form CA9176, available on gov.uk, requiring signatures from both the carer (applicant) and the Child Benefit claimant (parent), confirming the childcare arrangement for each specific tax year. Applications for a given tax year typically open from October following the end of that tax year, once HMRC's Child Benefit records for the year are finalised. Given claims can be backdated to April 2011, grandparents who've provided years of childcare and never claimed should check their eligibility now — there's no cost to applying, and the potential State Pension uplift is significant and lifelong.

What is the Specified Adult Childcare credit?
It's a National Insurance credit available to grandparents and other family members (aged over 16 but under State Pension age) who provide childcare for a child under 12 while the child's parent (who receives Child Benefit) is working and not using the National Insurance credit that automatically comes with Child Benefit themselves. The credit is worth a full qualifying year towards the State Pension, transferred from the working parent to the caring relative.
How much is a qualifying year of National Insurance worth towards the State Pension?
Each qualifying year builds towards the 35 years needed for a full new State Pension, currently worth £241.30/week (£12,547.60/year) in 2026/27. Roughly speaking, each additional qualifying year adds about 1/35th of the full pension — approximately £6.90/week, or around £359/year, paid for the rest of your retirement — making a single credit worth thousands of pounds over a typical retirement.
Can I claim the credit if I babysit occasionally, not full-time?
You need to have provided care for at least part of the week regularly — there's no strict minimum number of hours specified by HMRC, but the care needs to be a genuine, ongoing childcare arrangement (not one-off babysitting) for the qualifying tax year you're claiming for. Even relatively modest but consistent weekly care can qualify.
How far back can I claim the Specified Adult Childcare credit?
You can claim for any tax year since the scheme began in April 2011, as long as the child was under 12 throughout the period you're claiming for (or under 17 if the child has a disability) and the parent was entitled to Child Benefit and had a qualifying year of their own from other NI contributions/credits (meaning they don't need the automatic Child Benefit NI credit themselves). This means grandparents can potentially backdate claims for over a decade of childcare.
Does claiming this credit affect the parent's own National Insurance record?
No — the credit transfers the Class 3 National Insurance credit that would otherwise sit unused on the parent's record (because the parent is already getting a qualifying year through their own employment) to the caring grandparent instead. The parent doesn't lose anything; the credit that would otherwise go to waste is simply redirected.
How do I apply for the Specified Adult Childcare credit?
Apply using form CA9176, available on gov.uk, which requires both the applicant (the carer) and the Child Benefit claimant (the parent) to sign, confirming the childcare arrangement for each tax year being claimed. Processing can take several months, and you should apply after the end of the relevant tax year (from October following the tax year end, once Child Benefit records for that year are finalised).
