The arrival of a baby often sparks thoughts about the future — not just the immediate future of nappies and sleep deprivation, but the longer horizon of university, first cars, house deposits, and everything that lies ahead. Starting to save for your child's future early, even in small amounts, can make a meaningful difference over the 18-plus years you have before they might need the money. This guide covers the main savings options available to UK families, how much to save, and how to involve grandparents.
Compound interest — or compound investment returns — is one of the most powerful forces in personal finance. Money invested or saved early has longer to grow. A relatively modest monthly contribution started at birth grows to a significantly larger sum than the same contribution started at age 5, purely due to the additional years of compounding.
A practical illustration: £50 per month invested from birth, assuming a 5% average annual return (not guaranteed, but reasonable for a diversified equity investment over 18 years), would grow to approximately £16,800 by the time your child turns 18. The same contribution started when the child is 5 would grow to approximately £11,000. Starting 5 years earlier adds nearly £6,000 to the pot, for exactly the same monthly outlay.
This is not financial advice; it is an illustration of how time works in your favour when you start early.
The Junior Individual Savings Account (JISA, or Junior ISA) is the primary savings vehicle for children in the UK. Key features:
Cash Junior ISA: Money is held in a savings account and earns interest. It is simple, safe, and accessible for those uncomfortable with investment risk. The drawback is that interest rates, particularly for cash savings held over 18 years, are likely to be outpaced by inflation — meaning the real purchasing power of the money may actually decrease.
Stocks and Shares Junior ISA: Money is invested in financial markets (typically funds containing shares, bonds, or a mixture). Over long periods — and 18 years is a long period — equity investments have historically outperformed cash savings significantly. However, investments can fall in value as well as rise, and returns are not guaranteed.
For most families with an 18-year horizon, a Stocks and Shares Junior ISA is the more financially sound choice, but this is a personal decision based on your attitude to risk and your financial circumstances. A fee-free financial adviser can help if you are unsure.
Popular providers of Stocks and Shares Junior ISAs in the UK include Vanguard, Hargreaves Lansdown, AJ Bell, and Fidelity. Compare charges carefully — annual platform and fund charges compound just like returns, so low-cost index funds within a low-cost platform can make a significant difference over 18 years.
If your child was born between September 2002 and January 2011, they may have a Child Trust Fund (CTF) — a predecessor to the Junior ISA that received a government voucher on opening. CTFs are still running and can be transferred to a JISA. If you have lost track of a CTF, HMRC provides a tracing service. Children with a CTF cannot have a Junior ISA until the CTF is transferred, so it is worth tracking one down if applicable.
Some banks offer high-interest regular savings accounts for children, which can be a useful complement to a Junior ISA if you want to save a smaller amount separately or if you are approaching the £9,000 JISA annual limit.
Premium Bonds are issued by National Savings and Investments (NS&I), backed by the UK government, and instead of paying interest, they enter monthly prize draws. Grandparents and other family members can buy Premium Bonds on behalf of a child. The odds of winning vary, but they are secure (fully backed by the Treasury) and there is no risk to the capital. The prize fund rate in recent years has been relatively attractive compared to cash savings. Premium Bonds for children are held by a parent or guardian until the child turns 16.
Some financial planners suggest opening a Junior SIPP (Self-Invested Personal Pension) for a child — yes, even a baby can have a pension. A child can receive pension contributions of up to £2,880 per year net (the pension provider claims 20% tax relief, making the gross contribution £3,600). The money is locked away until at least the mid-50s (the minimum pension access age), making this appropriate only for long-term planning rather than university or house deposit goals. But the compounding effect over 50-plus years is extraordinary.
There is no right answer — it depends entirely on your financial situation. A few principles:
Many grandparents are keen to give financially to grandchildren and appreciate guidance on how to do so effectively.
Starting early is the most powerful thing you can do. Even tiny amounts, invested consistently over 18 years, can grow into something genuinely meaningful by the time your child needs it most.
