Education Savings Strategies for UK Families: JISAs, Trusts, Bonds and More

Education costs in the UK and internationally have risen faster than general inflation over the past two decades. For families planning ahead — whether for independent school fees, international school costs abroad, or university — the question is not simply how much to save but which savings vehicle is most appropriate given the tax rules, the intended timeline, and the family's overall financial structure.

This guide covers the main options, their tax treatment, and the planning considerations for each.

The Cost Context

To understand why planning is necessary, consider the scale of expenditure:

• UK independent schools: senior schools typically charge £15,000–£30,000 per year for day pupils and £35,000–£55,000 for boarding. Eton, Harrow, Winchester and similar schools were charging over £50,000 per year for boarding in 2025/26. For a family with two children in independent education for 7 years each, total fees of £400,000–£700,000 are not unusual.
• International schools abroad: top-tier international schools in Singapore (AIS, UWC), Dubai, Geneva and Hong Kong typically charge USD 25,000–55,000 per year. For expatriate families on locally-funded packages without a school fees allowance, this is a substantial out-of-pocket expense.
• University (UK): tuition fees for UK students at English universities rose to £9,535 per year in 2025/26 and to £9,790 in 2026/27, with annual RPI-linked increases now confirmed from autumn 2026 onwards. Living costs in London add a further £14,000–£18,000 per year. A three-year London degree costs around £70,000–£80,000 all-in. For overseas institutions — US, Canada, Australia — costs are higher.

None of these figures are speculative. Planning to fund them from income in the relevant years is difficult; building a dedicated savings fund over 10–18 years is more manageable.

Junior ISA (JISA)

The Junior ISA is the simplest and most accessible vehicle for education savings. The key features:

• Annual allowance of £9,000 per tax year (2026/27) — contributions can be made by anyone, including grandparents.
• Available as Cash JISA or Stocks and Shares JISA. For a 10+ year horizon, Stocks and Shares JISAs are generally preferable.
• Income and gains within the JISA are completely tax-free — no income tax, no CGT.
• The funds are locked until the child reaches 18, at which point the JISA converts to an adult ISA. The child can access the funds at 18 but cannot withdraw them before that date.
• No parental settlement rules apply: parents can contribute without triggering the "£100 income" rule that affects bare trusts.

The JISA is straightforward, regulated, FSCS-protected (up to £85,000), and requires no ongoing advice. The limitation is the relatively modest annual allowance and the absolute lock-in until 18 — the child gains full control at 18 with no restrictions on use.

Bare Trusts for Children

A bare trust holds assets in the child's name beneficially — the trustee (typically a parent) holds the legal title, but the child is the beneficial owner. The tax treatment is:

• Income: taxed on the child at their marginal rate. Since most children have no other income, the personal allowance (£12,570) and starter savings rate apply — meaning a significant amount of investment income can be earned tax-free.
• CGT: gains on disposal are taxed on the child at their rate, using the child's own annual exempt amount (£3,000 for 2026/27).

Parental settlement rules: if a parent (not a grandparent or other family member) settles assets into a bare trust for their own minor child, the "£100 rule" applies: if the total income from parent-settled funds exceeds £100 in a tax year, the entire income is taxed on the parent. This effectively removes the income tax benefit of a bare trust funded by parents.

However, if a grandparent or other third party settles into a bare trust, the parental settlement rules do not apply. This makes grandparent-to-grandchild bare trust contributions particularly efficient.

The key risk with a bare trust: the child gains full legal access at 18. There is no mechanism to prevent an 18-year-old from spending the funds on something other than education.

Offshore Investment Bonds

An offshore investment bond (typically structured as a whole-of-life insurance policy) invested through an Isle of Man, Channel Islands or similar offshore insurer has a distinctive tax treatment:

• Tax deferral: there is no UK tax on income or gains within the bond during accumulation. The full investment growth compounds gross.
• 5% withdrawal rule: the policyholder (typically a parent) can withdraw up to 5% of the original premium each year on a "tax-deferred" basis — in practice, each 5% withdrawal is treated as a return of capital and only taxed when cumulative withdrawals exceed the premium (or the policy is surrendered).
• Assignment to the child: before the child turns 18 (and while they are non-taxpayers), the bond can be assigned to the child as beneficiary. When the child subsequently surrenders the bond, the chargeable gain is taxed at the child's marginal rate — which, if they are a student with little other income, may be 0% or 20%.

The offshore bond is a sophisticated vehicle that requires proper advice. It is most effective where the investment period is long (10+ years), where significant sums are involved, and where the assignment strategy is planned in advance. Fees and charges must be considered — higher charges than a JISA can offset the tax deferral benefit.

Junior SIPP

A Junior Self-Invested Personal Pension (SIPP) allows contributions to be made for a child under 18. The rules are:

• Annual contribution limit: £2,880 net per year (£3,600 gross with basic-rate tax relief added).
• Contributions can be made by anyone — parents, grandparents, the child themselves if they have earned income.
• Funds cannot be accessed until the minimum pension age (57 from 2028).
• A SIPP opened at birth and contributed to until 18, then left invested until 57, benefits from approximately 40 years of compound growth. Small contributions at birth can grow substantially.

A Junior SIPP is not useful for education funding — the funds are locked until 57. However, it is a powerful generational wealth tool: grandparents or parents contributing £2,880 per year from birth until 18 create a pension pot that, with 40 years of investment growth, can be a meaningful retirement fund regardless of the child's own career earnings.

Comparing the Options

Vehicle	Annual limit	Tax-free growth	Access	Parental settlement risk
Junior ISA	£9,000	Yes	At 18	No
Bare trust	Unlimited	Via child's allowances	At 18 (legal), earlier practical	If parent settles
Offshore bond	Unlimited	Deferred	Any time (tax implications on encashment)	No
Junior SIPP	£2,880 net	Yes	At 57	No

For most families, a combination approach works best: maximise the JISA each year as the core vehicle; use grandparent-funded bare trusts or offshore bonds for larger contributions; consider a Junior SIPP for very long-term generational wealth planning.

Interaction With School Fee Payments

Existing savings must be deployed carefully to avoid triggering unnecessary tax on extraction. For example, cashing in a significant offshore bond in one year — to pay a year's school fees — may create a large chargeable gain in a single tax year, potentially taxed at higher rates than if encashments were spread. "Top slicing relief" for offshore bonds means the gain is assessed as if it arose evenly over the policy duration, but planning is still required.

Timing encashments around years of lower income — a parent taking a career break, or a grandparent in a lower-income year — can reduce the effective rate of tax on bond encashments significantly.
