Understanding the Specified Adult Childcare National Insurance Credit
Grandparents who look after a grandchild under the age of 12 may be able to claim Specified Adult Childcare National Insurance credits. These credits are not a cash payment; instead they fill gaps in a person’s National Insurance record and can increase the amount of State Pension they receive later in life. The scheme is aimed at those whose working hours have been reduced, who have stopped work temporarily, who earn too little to pay National Insurance, who already have gaps in their record, or who are not receiving another qualifying credit.
Who can claim the credit
To be eligible you must have cared for a related child who was under 12 years old at the time the care was provided. You need to have been aged 16 or older but still below State Pension age while providing that care, and you must be ordinarily resident in the United Kingdom, excluding the Channel Islands and the Isle of Man. The child’s parent or main carer must have been receiving Child Benefit for that child, and they must not need the associated National Insurance credit themselves. Finally, the parent must agree to the transfer of the credit to you. The scheme is not limited to grandparents; great‑grandparents, adult siblings, aunts, uncles and certain relatives of the parent’s spouse or partner can also qualify.
How the credit is transferred
When a parent claims Child Benefit for a child under 12 they normally receive an automatic National Insurance credit. If that parent already builds a qualifying year through employment or self‑employment they may not need the credit, and it can be transferred to the grandparent or another eligible relative who provided the childcare. The parent or main carer must give their consent and supply their details on the application form. Only one credit is available for each Child Benefit claim, so if two grandparents share the care the parent decides who receives it. If grandparents look after grandchildren belonging to two different adult children there could be two separate Child Benefit claims and therefore two credits available.
What the credit is worth
The full new State Pension is £241.30 per week for the 2026/27 tax year. Under the current system one additional qualifying year adds roughly one thirty‑fifth of that amount, which works out to about £6.89 per week or just over £358 per year. Over a typical 20‑year retirement this could amount to more than £7,000 before any future State Pension increases are taken into account. The actual uplift depends on your individual National Insurance history, whether you were contracted out in the past, and whether you are already on track to receive the full pension. You can check your personal forecast using the government’s free State Pension forecast service to see if filling a gap would improve your outlook.
When you can apply
Applications must wait until 31 October after the end of the relevant tax year. This delay gives HMRC time to verify whether the parent has already built a qualifying National Insurance year and can therefore transfer the childcare credit. For example, claims for care provided during the 2025/26 tax year can be made from 31 October 2026. You can also make retrospective claims for eligible childcare that dates back as far as 6 April 2011, meaning grandparents whose grandchildren are now teenagers may still be able to plug old gaps in their record. Full rules and the relevant application form are available through the government’s Specified Adult Childcare credits service.
Things to consider before claiming
It is important that the parent does not transfer the credit if they still need it to complete their own qualifying year. Both parties should review their National Insurance records first. If you receive regular payments from the parents for your time or expenses, those amounts could be treated as taxable income. Keeping a simple log of what you receive and what you spend on items such as petrol, food or days out will help you stay on top of any tax obligations. If the arrangement becomes regular paid work or your trading income exceeds the tax‑free trading allowance you may need to inform HMRC. Additional earnings can affect means‑tested benefits such as Universal Credit, Housing Benefit or Pension Credit, so grandparents who are already receiving such support should check the impact before agreeing to regular payment.
Payments from parents
Parents may choose to reimburse you for petrol, food, days out or other out‑of‑pocket costs, or they may agree to pay you for the time you spend providing care. While such reimbursements are permissible, they are not covered by the National Insurance credit scheme and must be handled separately for tax purposes.
Tax‑Free Childcare and other schemes
Tax‑Free Childcare cannot normally be used to pay for informal care provided by a grandparent. In England and Scotland it may only be used when the relative is a registered childminder and looks after the child outside the child’s own home. Similar restrictions apply in Wales, while Northern Ireland has its own approval requirements that can be stricter when the provider is a family member. England’s Free Childcare for Working Parents scheme also does not cover grandparent‑provided informal care. Parents should use the government’s childcare support checker before attempting to claim any of these schemes for care delivered by a relative.
Registration as a childminder
Looking after your own grandchildren under a private family arrangement does not usually require you to register as a childminder. The requirement only arises if you begin to care for unrelated children for payment or if you start operating a wider childcare business. Registration rules differ across England, Scotland, Wales and Northern Ireland, so anyone considering a shift to paid childcare work should consult their local authority or the relevant childcare regulator.
Parental responsibility
Regularly looking after a grandchild does not automatically give you parental responsibility. Parental responsibility covers legal powers and duties such as decisions about education, consent to medical treatment and applying for a passport. For occasional school runs or after‑school care a formal legal arrangement is not normally needed, but the school must be given permission to release the child to you. Many schools use collection lists, passwords or identification checks, and families should update these details before the first day of term rather than waiting until the first collection.
Car seat requirements
The driver is legally responsible for ensuring that any child under 14 uses the correct restraint. Children must normally use an appropriate child car seat until they are either 12 years old or 135 cm tall, whichever comes first. After that point they must use an adult seat belt. A seat that fits correctly in the parent’s car may not be suitable for the grandparent’s vehicle, so it should be checked and fitted before the first school run. Full details and any limited exceptions are set out in the government’s child car seat guidance.
Back‑to‑school checklist for grandparents
Before the new term begins, ask the school to add you to its approved collection list and share any collection password or identification requirements. Make sure the correct car seat is fitted and checked in your vehicle. Provide the school with emergency contact numbers and write down details of the child’s allergies, medication and any medical conditions. Agree with the parents how petrol, food and other expenses will be covered, and keep a simple record of the weeks in which you provide childcare. Finally, verify whether Specified Adult Childcare credits could help fill a gap in your National Insurance record and improve your future State Pension.
Final thoughts
Grandparents provide a huge amount of unpaid childcare that often makes it possible for parents to stay in work. The Specified Adult Childcare National Insurance credit does not cover petrol, snacks or emergency stationery runs, but it can protect your National Insurance record and make a meaningful difference to your retirement income. The key is to check your eligibility, confirm that the parent does not need the credit, and apply within the allowed time window. Remember that these credits are designed to fill gaps in your National Insurance history rather than to provide an immediate cash payment, so reviewing both your own and the parent’s records before requesting a transfer is essential.
