- University Savings Plan. Opening a Cash JISA for a 5-year-old and contributing £100/month until age 18 could give a tax-free pot of around £18,000 (assuming 3% average annual interest).
- First Home Deposit. Contributing £2,000 annually into a Stocks & Shares JISA for 15 years could result in over £40,000 (assuming 5% growth), enough for a significant deposit outside London.
- Lifetime Financial Kickstart. Funding a child’s pension with £2,880/year (grossed up to £3,600 with tax relief) from birth until age 18 could grow to over £100,000 by age 57, even with modest returns.

What Type of Accounts Can Grandparents Open for Their Grandchildren?
Opening a savings or investment account for your grandchild is not only a generous gesture, but also a valuable opportunity to introduce sound financial habits from an early age.
It encourages your nephews to understand the importance of saving, planning, and delayed gratification — lessons that will serve them well throughout life.
As a grandparent in the UK, you have a number of options depending on your goals, how much you wish to contribute, and the level of control or flexibility you require. These include:
- Children’s regular savings accounts – Typically offered by high street banks and building societies, these accounts allow you to make small, regular contributions. They often offer competitive interest rates, although some may require a minimum monthly deposit.
- Junior ISAs (JISAs) – Tax-free investment or cash accounts that can only be opened by a parent or legal guardian, but can be funded by anyone. The annual allowance for 2025/26 is £9,000.
- Children’s pension schemes – Long-term savings vehicles with generous tax advantages, ideal if you’re thinking decades ahead. You can contribute up to £2,880 per year (grossed up to £3,600 with tax relief).
- Trusts – Useful if you want to retain some control over how and when the funds are accessed. They can be tailored to suit complex family or tax planning needs.
- NS&I Premium Bonds – Available to under-16s with an adult nominee. While they don’t pay interest, they offer the chance to win tax-free prizes in monthly draws.
What’s the Best Way to Set Up a Savings Account for a Grandchild?
The best savings account for your grandchild will depend on a few key factors:
- Purpose of the savings – Is it for general use, education, a house deposit, or long-term wealth?
- Access requirements – Do you want the funds to be available at 18, or locked away for longer?
- Contribution frequency – Are you planning to make a lump sum deposit, regular payments, or occasional gifts?
To open a basic savings account in your grandchild’s name, most UK providers will require proof of identity and address for both the child and the adult managing the account, typically a birth certificate for the child and valid ID for the account holder.
Savings accounts offer simplicity and predictability. Interest is accrued at a fixed or variable rate, and some providers offer bonus rates if a regular deposit is maintained. Funds are usually accessible as soon as the child reaches 16 or 18, depending on the account type and provider terms.
However, if you wish to limit how and when your grandchild can access the money, for example, to prevent them from spending it all at once, you might consider alternatives like a discretionary trust, Junior ISA, or child pension scheme.
Can I Open a Savings Account Online for My Grandchild?
Most UK banks and building societies now allow grandparents to open savings accounts online on behalf of a child, provided you can supply the necessary documentation. This typically includes:
- The child’s full name and date of birth
- A valid birth certificate
- Your own identification as the responsible adult managing the account
Some providers may require you to be a UK resident or an existing customer to apply online. Always check specific eligibility criteria before proceeding.
How Much Can a Grandparent Give to a Grandchild Tax-Free?
Thanks to current Inheritance Tax (IHT) rules, grandparents can gift up to £3,000 per tax year without it counting towards their estate for IHT purposes. This is known as the annual gift exemption.
- If unused, this allowance can be carried forward one tax year, meaning you could gift up to £6,000 if no gift was made in the previous year.
- Gifts above this limit may still be exempt if made as regular gifts out of surplus income, or if the donor survives seven years after making the gift.
These contributions can be made into the best ISAs for babies and children, savings accounts, pensions, or trusts, but it’s always advisable to consult a regulated financial adviser if you’re unsure about your tax position or estate planning strategy.
Can I buy premium bonds for my grandchildren?
Investment bonds for grandchildren can also be a good idea for helping to start building their financial wealth as part of a broader investment strategy. On behalf of the UK government, National Savings & Investments (NS&I) has issued premium bonds, a kind of savings account that may accrue interest over time. NS&I premium bonds for grandchildren can be a good option to start generating steady wealth since investors receive a chance to win up to £1,000,000 in a random drawing in place of interest.
Premium Bonds can be purchased by anyone who is 16 years old or older. For a grandchild under the age of 16, (great) grandparents may invest on their behalf, and you can put as little as £25 or as much as £50,000. Your grandchild won’t need to pay interest on Premium Bonds. However, this form of savings for grandchildren has no guaranteed return. Instead, for a chance to win tax-free prizes, your bonds can be entered into a monthly prize draw.
Common mistakes to avoid when investing and saving for your Grandchildren
Here are some common mistakes to avoid when investing and saving for your grandchildren.
Choosing the wrong savings or investment account: Choosing the right savings and investment account is important as interest rates can have an impact on the total savings amount. A JISA is a popular option for grandparents, but explore other options such as a child’s trust, premium bonds, and other investment accounts. Just make sure your savings for grandchildren suits your financial needs and goals.
Non-diversified investments: Not diversifying can be very risky. Instead of investing the funds in one type of investment, spread it across different assets, such as stocks, bonds, and mutual funds.
Tax implications: Not considering the tax implications on your savings for grandchildren can impact how much your grandchildren may receive. So, it is important to understand the different tax implications of saving and investing for grandchildren. Consult with a financial advisor is recommended.
Not starting early. The earlier you start investing, the better, as the money has more time to grow through compound interest. A non-early start can significantly reduce the amount of money available for your grandchildren’s future.
Lack of communication: Not communicating your intentions with your grandchildren can have a negative effect as they might not be aware of the intended purpose of the money. Grandparents should ensure proper communication with their grandchildren about their intentions.

A final way to ensure your family’s financial security in the future is to decide to leave some of your fortunes to your grandchildren through your last will and testament. There are several ways to leave money behind, but there are taxes to pay. Some options include leaving a large sum in an individual savings account (ISA), topping up an ISA on a regular basis, or leaving a big sum in your will.
