Building wealth for your grandchildren

A forward-thinking guide to building a substantial legacy for tomorrow
As a grandparent, you have a unique opportunity to contribute to your grandchildren’s future in a profoundly meaningful way. Beyond cherished memories and life lessons, providing a financial head start can make a significant difference as they navigate key milestones in life.

Whether you envision helping with university fees, a deposit for their first home, or simply laying a foundation of financial security, thoughtful planning today can grow into a substantial legacy for tomorrow.

Investing on their behalf turns your generosity into a tangible asset that grows with them. With a range of tax-efficient options, you can make your contributions work harder over the long term. Navigating these choices enables you to support the next generation effectively, aligns with your financial circumstances, and ensures your wealth is passed on in a structured and beneficial way.

All contribution limits in this article apply to the 2025/26 tax year, which runs from 6 April to 5 April.

Exploring tax-efficient accounts
It is often more tax-efficient for grandparents to save for their grandchildren than for their own children. A Junior ISA (JISA) is a popular starting point, offering tax-efficient growth on contributions up to the annual limit of £9,000. The money is locked away until your grandchild turns 18, at which point they gain control of the funds. Importantly, contributions to a JISA are generally outside your estate for Inheritance Tax (IHT) purposes, provided you survive for seven years after making the gift.

Additionally, a Junior Self-Invested Personal Pension (SIPP) is an excellent tool for long-term planning. You can contribute up to £2,880 each tax year, with 20% government tax relief, bringing the total to £3,600. While these funds cannot be accessed until retirement age (currently 57), the power of decades of compound growth can create a substantial pension pot, giving your grandchild an incredible start to their retirement planning.

Gifting, trusts and Lifetime ISAs
Beyond dedicated children’s accounts, you can use annual gifting allowances to reduce your potential IHT liability. Each grandparent can gift up to £3,000 per year without it being added to their estate. For greater control over how and when your grandchild receives the money, establishing a trust can be a prudent option. This allows you to set specific conditions for the funds, such as for education or a property deposit.

Once your grandchild reaches 18, they can open a Lifetime ISA (LISA). They can save up to £4,000 annually until they are 50, and the government will add a 25% bonus to their contributions. The money can be used tax-free for a first home purchase or for retirement from age 60, making it a highly attractive savings vehicle for young adults.
