Is Private School Worth It UK? The Maths After VAT

Private school fees in the UK became significantly more expensive on 1 January 2025, when VAT at the standard 20% rate was applied to independent school education for the first time. The debate that followed focused almost entirely on the politics: was this a fair contribution from those who can afford it, or a tax on aspiration that would force middle-income families out of independent education? Both sides argued past each other for months.

The question that got almost no airtime is the one that matters most to anyone sitting with a school fee invoice: is it actually worth it? And, now that the cost has risen by up to 20%, does the maths still hold?

This is a Settle It piece on private education in the UK. We are going to take a side - and the side we are taking is the opportunity cost. But we will give the other side a fair hearing, because it is not as weak as the detractors suggest.

Is private school worth it in the UK? It depends on your local state school, your child's specific needs, and whether you have done the opportunity-cost maths. The average day fees of £17,000 per year, invested in a global tracker instead over 14 years, could grow to around £590,000 by the time the child turns 30 (illustrative, at 5% real return). That does not mean private school is wrong - but most families making this decision have never put that number on the table.

What VAT actually did to private school fees

The policy is now law. From 1 January 2025, all education and boarding services provided by a private school are subject to VAT at the standard rate of 20%. Pre-payments made on or after 29 July 2024 for terms beginning on or after January 2025 were also caught by the anti-forestalling provision. There is no ambiguity about the policy being in force.

As of June 2026, the policy has faced legal challenges brought by a number of independent schools through the courts. These proceedings remain ongoing and unresolved at the time of writing. The policy continues in full effect while litigation runs its course. Whether any challenge succeeds, and what remedy it might produce, is unknown - this article does not speculate on the outcome.

What the government expected to happen - and what largely did - is that fees rose by around 10% on average. This is lower than the full 20% VAT rate because schools can now reclaim VAT on their own inputs (energy bills, building works, supplies), which partially offsets the cost of charging VAT on fees. Some schools absorbed part of the impact. Others passed the full 20% on. The outcome varied significantly by institution.

For context: the ISC Census 2024 (the Independent Schools Council's annual survey of its member schools, the latest available at the time of writing) showed average day fees of around £16,000 to £18,000 per year for secondary pupils at ISC-member schools, with boarding fees averaging closer to £40,000 per year. These are approximate figures from the ISC's own published data for the academic year covered by the 2024 census. Non-ISC schools, which tend to be smaller and more local, often charge less. The ISC figures represent around 1,400 schools covering roughly half a million pupils.

A 10% average increase on a £17,000 annual day fee adds around £1,700 a year. Over 13 years of secondary and primary education, that is an additional £22,100 compared with the pre-VAT position - even before you account for the underlying trend of fee inflation, which has run well ahead of CPI for decades. Gov.uk documents note that average school fees rose 75% in real terms between 2000 and 2024.

The opportunity cost nobody calculates

Suppose you are paying average ISC day fees: call it £17,000 per year from reception to A-levels, a period of roughly 13 to 14 years. Including a 10% VAT-related uplift that started in January 2025 and using round numbers, the all-in cost across those 14 years sits somewhere in the region of £250,000 to £270,000. If you are paying boarding fees at £40,000 a year, the 14-year total is closer to £600,000.

The question is not whether you can afford that. The question is what else that money could do.

The illustrative maths (all figures are illustrative, assume the stated growth rates, and must not be read as a guarantee or prediction of investment returns):

Assumptions: £17,000 per year invested at the start of each year from age 4 to age 18 (14 contributions), into a globally diversified equity index fund, at an assumed real annual return of 5% after inflation. The 5% figure is a conventional long-run assumption for a diversified global equity portfolio; actual returns will be higher or lower in any given period. All investment carries risk of loss.

Under these assumptions, the invested pot at the end of year 14 (when the child turns 18) would be approximately £330,000 in today's money. Left to compound for a further 12 years until the child is 30, still at 5% real, that grows to approximately £590,000.

At boarding-fee levels (£40,000 per year), the equivalent pot at 18 is approximately £770,000, growing to roughly £1.37 million by age 30.

These numbers are large. They are also entirely logical - they are just the power of compounding applied consistently over a long period, a mechanism we celebrate in every pension article but rarely apply to this conversation.

The day-fee alternative is not the promise of a better outcome. It is a conditional: if you invested the fees instead of spending them on private education, here is where the maths points, all else equal. The question then becomes whether private education delivers enough additional value to justify forgoing that pot.

The honest answer is: nobody knows with certainty, and the research is contested.

There is credible evidence that selective private schools produce better academic results, but much of this disappears when you control for the socioeconomic background of the intake. Children who go to private school largely succeed because of the environment they come from, not solely because of the school. The school adds something - smaller class sizes, broader extracurricular access, network effects that persist into the job market - but the "something" is hard to quantify and unevenly distributed even within the private sector.

Attributing cause rather than correlation in education outcomes is one of the harder statistical problems in social science. Any claim that private education guarantees a particular outcome should be treated with scepticism. And any claim that it makes no difference whatsoever is equally dubious. These are contested research questions, not settled facts. The honest position is uncertainty, not confidence in either direction.

For the bigger picture on how wealth compounds across generations - and why the decision about how to deploy a large sum during a child's formative years matters well beyond the school gates - the generational wealth piece on why £100k at 25 beats £500k at 60 puts the numbers in context.

The case for paying anyway

Fair is fair. The opportunity-cost framing, taken to its logical extreme, would also tell you to never own a car (invest the payments instead), never holiday abroad (invest the flights instead), and never renovate your kitchen. At some point, money is for living - and many parents genuinely believe that the environment their child spends thirteen years in shapes who that child becomes in ways that no investment pot can replicate.

Some things about private schooling are real and concrete:

• Class sizes. Average class sizes in the independent sector run around 10 to 15 pupils compared with 28 to 30 in state schools. If your child learns better in a smaller group - especially if they have additional needs - this is not negligible.
• The breadth question. Many private schools offer drama, music, sport, art and other activities as part of the standard timetable rather than as optional extras. Whether this matters depends entirely on your child and your priorities. For some families it is the reason.
• Access to networks. The professional networks built through selective private schools, especially at the upper end of the market, persist into adult life in ways that state schools simply do not replicate. This is partly unfair and partly real. Naming it is not an endorsement of it.
• The state school lottery. The UK state sector is not uniform. A child in a well-functioning comprehensive in a prosperous catchment area has access to a different education from a child in an underfunded school in a disadvantaged area. If the choice is between a weak local state option and a solid local independent, the opportunity-cost maths shifts.

None of these are arguments for private schooling in the abstract. They are reasons why the maths alone cannot answer the question for your family.

And there is a macro point here that tends to get lost in the debate. A system where outcomes depend on whether your parents can afford fees is not a meritocracy - it is a wealth transfer dressed up as educational philosophy. Why the UK won't tax wealth covers the structural picture in more detail, but the private school premium is one of its clearest expressions: those who can afford to buy better outcomes do, and the rest of us live with what remains.

The grandparent angle: IHT and fee gifting

Private school fees are often funded partly by grandparents. This is not rare - it is one of the most common forms of intergenerational wealth transfer in the UK. And since 1 January 2025, paying those fees has an interesting intersection with inheritance tax planning.

Under UK IHT rules, gifts paid directly from a grandparent's income - regular payments made out of surplus income that do not reduce the giver's standard of living - can be exempt from IHT entirely under the "normal expenditure out of income" exemption. Termly school fee payments, if they meet this test, could in principle qualify. This is a genuine planning opportunity for grandparents with substantial investment income or pension income who face a taxable estate.

Beyond that, even ordinary gifts are subject to the standard rules:

• Annual exemption: each person can give £3,000 per year free of IHT, verified against the current gov.uk guidance. Two grandparents can jointly give £6,000 per year.
• The 7-year rule (Potentially Exempt Transfers): gifts above the annual exemption become PETs. If the giver survives 7 years, no IHT is due. If they die within 7 years, taper relief applies - but only if the total gifts exceed the £325,000 nil rate band.
• The nil rate band: each individual has a £325,000 IHT-free threshold (current figure, verified against gov.uk). The standard IHT rate above this is 40%.

If a grandparent has a taxable estate and is funding school fees anyway, doing so via properly structured gifts rather than via the parents could systematically reduce an IHT bill at 40%. The £17,000 annual day fee paid directly from a surplus-income grandparent could, in the right circumstances, pass through the estate free of inheritance tax that would otherwise cost £6,800 (40% of £17,000) in the future.

This is complex. The "normal expenditure out of income" exemption has specific HMRC requirements and the consequences of getting it wrong can be expensive. Get proper advice from a qualified adviser before relying on it. The principle is real; the execution needs professional oversight.

For a deeper look at how the IHT system works and where the planning opportunities sit, read the inheritance tax UK guide. For anyone starting to think seriously about what their estate looks like and what happens to it, do you need a will? is the place to start from the estate planning side.

Our verdict

Private school fees in the UK, post-VAT, are a very large financial commitment. The illustrative opportunity-cost maths - roughly £330,000 to £590,000 in today's money for the average day-school spend, depending on when you measure it - is real and should be acknowledged rather than avoided.

The honest case against private education is not that it is worthless. It is that the additional value it delivers over a good state school is not reliably quantifiable, and the families paying for it are often paying for correlation rather than causation. A driven, well-supported child from a financially stable home performs well regardless of school sector, in the main. The school is not irrelevant, but it is less determinative than the bill suggests.

The honest case for private education is that for families where the local state option is weak, where the child has specific needs better served in a smaller environment, or where the network and breadth effects are genuinely valued, the spend is defensible. Money is for living, and parents who believe deeply in what they are buying deserve to be treated as adults making an informed choice rather than people to be corrected.

Our side: the opportunity cost is systematically underweighted. Most families making this decision have not done the invested-alternative calculation. Do the maths. If you run the numbers and still decide private school is worth it, fair play. If you discover you have never done the maths, do them now - before you commit to a fee schedule that may run for over a decade.

And if grandparents are involved in the funding, talk to a specialist about the IHT structure before writing the first cheque.

Frequently Asked Questions

How much money can a grandparent give a grandchild tax-free in the UK?

Each person has a £3,000 annual IHT exemption to give away each tax year, so two grandparents can jointly give £6,000 per year tax-free. Additional gifts are Potentially Exempt Transfers (PETs) - if the giver survives 7 years from the date of the gift, no IHT is due on that gift. Grandparents can also give £2,500 tax-free to a grandchild getting married or entering a civil partnership, on top of the annual exemption. All figures verified against gov.uk in June 2026.

Can parents claim VAT back on private school fees?

No. VAT paid on school fees by parents cannot be reclaimed by parents. Only VAT-registered businesses can reclaim VAT on their purchases, and private individuals paying school fees are not in business for this purpose. The schools themselves can now reclaim VAT on their own costs (energy, building works, supplies) as a result of being VAT-registered, which is why the net fee increase is typically closer to 10% rather than the full 20%.

Will VAT be removed from private school fees?

As of June 2026, the VAT measure remains in full effect. Legal challenges have been mounted by private schools through the courts, and those proceedings are ongoing and unresolved. The outcome is uncertain and this article does not speculate on it. The policy was legislated by Parliament and would require either a successful court ruling or a future change of government policy to remove.

How do parents afford private school fees in the UK?

The most common routes are: using savings built up over years before the child starts school, drawing on investment income, grandparent contributions (often structured around IHT planning as described above), using equity released from property, employer salary arrangements in some cases, and school bursaries or scholarships for families who qualify. Very few families paying private school fees are doing so purely from a current monthly salary without prior planning.

Is the £17,000 invested-alternative calculation realistic?

The calculation in this article is illustrative. It uses a 5% real annual return on a globally diversified equity portfolio, applied to £17,000 per year across 14 years. Actual returns will differ - markets have years of strong gains and years of losses. The 5% figure is a common long-run assumption used in financial planning and is not a prediction or guarantee. The purpose of the maths is to make the scale of the opportunity cost visible, not to promise any specific outcome. All investment involves risk of loss.

What is the "normal expenditure out of income" IHT exemption for school fees?

It is an HMRC exemption that can apply when gifts are regular, come from income (not capital), and do not reduce the giver's standard of living. If a grandparent with significant investment or pension income pays school fees termly and meets all three tests, those payments may fall outside their estate for IHT purposes - potentially saving 40% on amounts that would otherwise form part of a taxable estate. The rules have specific HMRC requirements and are easy to get wrong. Consult a qualified adviser before relying on this exemption.

Does private school really make a difference in the UK?

The honest answer is: less than the cost implies. Selective private schools do produce stronger academic outcomes on average, but most of this effect disappears once you control for parental income, home environment, and prior attainment. The school adds something real - smaller classes, breadth of curriculum, professional networks that persist into careers - but the effect is hard to isolate and uneven even within the private sector. A child from a financially stable, engaged household tends to do well regardless of school type.

Do kids do better at private school?

On average, privately educated pupils achieve higher grades at GCSE and A-level and are more likely to gain places at Russell Group universities. But these headline figures reflect the intake as much as the school. Children from wealthier, more stable homes outperform on almost every educational metric - and private schools disproportionately educate those children. The added value of the school itself, once background is controlled for, is measurable but smaller than the raw numbers suggest.

What salary do you need to afford private school in the UK?

Average ISC day fees run around £17,000 per year (ISC Census 2024, the latest available). As a rough rule of thumb, financial planners suggest fees should not exceed 10-15% of gross household income to remain manageable without liquidating savings. That implies a joint household income of roughly £113,000 to £170,000 per year for average day school, before you account for holidays, uniform, extracurriculars, and any sibling fees. Boarding at £40,000 per year would require £267,000 to £400,000 of household income on the same test. These thresholds explain why private education is largely a top-decile spend.

Is private school better for children with dyslexia?

It can be, but it depends heavily on the individual school. Many independent schools have smaller class sizes and dedicated learning support units that can be genuinely more responsive to pupils with dyslexia or other learning differences. Some state schools have excellent specialist provision too. The key is to ask specifically about the school's SEN staffing ratio, the qualifications of its learning support team, and what tailored programmes are in place - not just assume the private label means better support.
