The short answer

To use a lump sum for education, map every fee date for each child, then split the money by when it's needed. Keep the next one to three years of fees safe in cash or short-term deposits. Invest the money for later years for growth — the further away the fees, the more growth can do: at 8% a year, about £37,000 invested today could fund £100,000 of fees starting in eleven years. Invest all at once or in stages, in a suitable bond, platform or trust, in the currency of the fees, and move money to safety as each stage approaches. If there's a gap, add a monthly plan. Lawrence will plan it with you, free.

Where education lump sums come from

Each source comes with its own tax position, timing and currency — a UK house sale arrives in pounds, a Thai bonus in baht, an inheritance perhaps in several currencies. Before deciding how to use the money, it's worth checking the tax in both countries and how best to move it. Our guide to lump-sum investment planning for expats covers the first ninety days.

Step 1: Map the fees to the dates

The secret to making a lump sum go further is to match each part of it to a specific bill. Write down, for each child, every year of school and university still to come, the likely cost, and the date it's due. Then group the money into three pots:

• Now (the next one to three years) — fees that will definitely be paid soon. Keep this money safe, in cash or short-term deposits, in the currency of the fees.
• Soon (three to seven years) — invested cautiously, in a mix of bonds and some shares, moving to cash as each year approaches.
• Later (seven years or more) — invested mainly for growth, because there's time to recover from market falls.

As each year passes, money moves from "later" to "soon" to "now". It's a simple discipline that protects next term's fees from a market fall while letting the long-term money grow.

Matching a lump sum to fee dates

How to split an education lump sum by when the money is needed.

A general approach. The right split depends on your other income, the amount and your attitude to risk.

How far can a lump sum go?

Time is the lump sum's best friend. At 8% a year, £100,000 invested when a child is five could grow to about £272,000 by eighteen; invested at ten, about £185,000; at fifteen, about £126,000.

Looked at the other way, the further away the fees, the less you need to set aside today. To fund five years of fees at £20,000 a year — £100,000 in total — starting in six years, you'd need to invest about £54,000 today at 8% a year. If those fees start in eleven years, about £37,000 would do. That's why money for a young child's university years can work so hard.

Growth isn't guaranteed, and real returns will vary year to year — which is exactly why the money for the next few years should be kept safe, and the plan reviewed every year.

What you need to set aside today

Illustration only, at 8% a year. Money due within three years is better held in cash, which grows more slowly.

Sharing a lump sum between several children

With two or three children, a single lump sum has to stretch across different timelines. The youngest child's fees are furthest away, so their share can be invested for growth for longest; the eldest's are nearest, so more of their share needs to be safe. A fair split isn't always an equal one in pounds today — it's one that aims to cover a similar share of each child's education.

• Draw one timeline with every child's school and university years side by side.
• Give each child their own pot — separate accounts or bond segments make it easy to track.
• Invest the youngest child's share more for growth.
• Agree what's fair as a family, especially in blended families or when grandparents contribute.

All at once, or in stages?

For the long-term "later" pot, the question is whether to invest it all at once or feed it in over several months. Research by Vanguard found that investing a lump sum straight away beat phasing it in about two-thirds of the time, simply because markets rise more often than they fall. But phasing can make sense if a sudden fall soon after investing would worry you — it trades a little expected return for peace of mind.

Either way, the "now" pot should never be invested in shares: money for next year's fees belongs in cash. Our guide to investing a lump sum or saving monthly explains the trade-off.

Where to start

A lump sum matched to every fee date, and the right way to move it between currencies.

Where to hold an education lump sum

Cash and deposits

For the "now" pot: easy access, no investment risk, ideally in the currency of the fees. Interest is modest, and Thai bank interest is taxed at 15% at source.

International investment platforms

Flexible, low-cost and multi-currency. Ardan International, for example, has no minimum investment, a 0.4% yearly account fee, up to 11 currencies and a free beneficiary trust. Platforms suit families who want to draw money as fees fall due.

Offshore investment bonds

Popular for larger sums, especially with trusts. You can usually withdraw up to 5% of the amount invested each year for twenty years with UK tax deferred, and bonds can be split into segments to hand to a child or cash in stages. Options include RL360 Oracle (from US$28,000) and PIMS (from £45,000), Hansard Global Select and Investors Trust's lump-sum plans.

Using pension tax-free cash for education

Parents and grandparents over 55 sometimes consider using pension tax-free cash — usually up to 25% of a pension, within the £268,275 Lump Sum Allowance — to pay for education. It can work, but it's worth thinking carefully first:

• The minimum pension age rises to 57 from 6 April 2028.
• Money taken out stops growing inside a tax-efficient pension.
• Your own retirement comes first — children can borrow for university; you can't borrow for retirement.
• Inheritance tax changes from April 2027 bring unused pensions into UK inheritance tax, which may make drawing some pension money for family goals more attractive for some.
• Thai tax may apply to money brought into Thailand if you're Thai tax resident.

Our guide to moving from saving to retirement income explains how tax-free cash fits a wider plan.

Drawing the money as fees fall due

Once the plan is in place, running it is straightforward. Each year, before the new school or university year, move the coming year's fees from the "soon" pot into cash, top up "soon" from "later" if markets have been good, and fix the exchange rate for the fees if they're in a different currency. If markets have fallen, leave the growth pot alone and use the cash and cautious pots instead — that's exactly what they're for. A short yearly review keeps everything on track as children move from primary to secondary school and on to university.

Combining a lump sum with monthly saving

A lump sum and monthly saving work well together. The lump sum covers the nearer school years and gives the long-term pot a head start; a monthly plan builds up money for the years the lump sum won't stretch to — often university. If your sums show a gap, a modest monthly plan started now, with growth of around 8% a year, can close it. Our guide to regular savings for a child's education shows how much to save.

Currency: moving and holding the money

A lump sum often arrives in one currency while the fees are in another — a UK house sale in pounds, Thai school fees in baht, a UK university in pounds again. Moving a large sum through a high-street bank can cost thousands of pounds more than a specialist.

• Hold each pot in the currency of its fees — baht for Thai school years, pounds for a UK university.
• Use a specialist to convert large sums at a competitive rate.
• Fix the rate for known future fees with a forward contract.
• Convert in stages if you're unsure about the rate.

Our guide to large GBP to THB transfers covers the practicalities.

Tax in two countries

How the lump sum is taxed depends on where it came from and where you live. A UK house sale may be free of UK capital gains tax if it was your main home; a pension lump sum is usually tax-free up to 25%; an inheritance may have had UK inheritance tax deducted. If you're Thai tax resident, foreign income arising from 2024 that you bring into Thailand can be taxable, while savings built up before you became resident are treated differently — so keep clear records of what each transfer is. Investment wrappers such as offshore bonds can defer tax on growth. Our guide to tax residence and international investments explains the rules.

Ring-fencing the money with a trust

Placing an education lump sum in trust can ring-fence it for your children, keep it separate from your other money, help with inheritance tax planning and make sure it reaches them smoothly if something happens to you. Offshore bonds work particularly well in trust, and some platforms offer a free beneficiary trust. Grandparents often use trusts to fund grandchildren's education; Thai gift tax exempts gifts from grandparents to grandchildren up to ฿20 million a year.

Protecting the plan

A lump sum already set aside is the best protection of all — the money is there whatever happens. But if the lump sum covers only part of the bill, and income or monthly saving covers the rest, life cover and income protection for the main earner keep the remainder on track. Health insurance for the family stops a medical bill eating into the education fund. We take leads for insurance and can introduce you to specialists who arrange cover for expat families.

The most common mistakes

1. Leaving it all in a bank account for years while fees rise.
2. Investing next year's fees in shares.
3. Spending it on other things because it isn't ring-fenced.
4. Converting at a poor bank rate.
5. Holding it in the wrong currency for the fees.
6. Ignoring tax in the UK or Thailand.
7. Choosing a product with long lock-ins when you'll need the money soon.
8. Never reviewing as children move through school.

Three real-world examples

Simon and Ying: the UK house sale

Simon and Ying sold their UK home for £300,000 after settling in Bangkok, with two children aged 6 and 9. They kept three years of fees in baht, invested £120,000 cautiously for the senior school years and £90,000 for growth for university, and fixed the exchange rate each year for the coming fees.

Helen: an inheritance for her grandchildren

Helen inherited £150,000 and wanted it to pay for her two grandchildren's university. Placed in an offshore bond in trust, divided into segments for each child, it's invested for growth with more than ten years to go.

Ravi: the bonus and the gap

Ravi received a £40,000 bonus when his daughter was 12. It covered her next two years of fees safely, with a monthly plan added for the senior years and university.

Your lump-sum checklist

• I've mapped every fee date for each child.
• The next one to three years are safe in cash.
• Later money is invested for growth.
• Each pot is in the right currency.
• I've chosen a suitable bond, platform or trust.
• I've checked the tax in both countries.
• Any gap is covered by a monthly plan.
• I move money to safety as each stage approaches, and review yearly.

Keeping a large sum safe

A large sum attracts attention from fraudsters. Be wary of anyone who contacts you about investing it, of guaranteed high returns, and of requests to send money anywhere other than a well-known provider in your name. Confirm school payment details directly with the school, and use a private, protected connection on public Wi-Fi.
