Private school fees are a significant financial commitment — and since the January 2025 VAT change, a considerably larger one than before. The decision to send children to private school involves far more than money, but for many families, the financial question is the deciding factor.
This guide looks honestly at the numbers.
What Does Private School Cost in 2026?
After the removal of the VAT exemption in January 2025, UK private school fees increased substantially:
| School type | Average annual fees (2026) | With 2 children (7 years, age 11–18) |
|---|---|---|
| Day preparatory (ages 4–11) | £14,000–£20,000 | £100,000–£140,000 |
| Day senior (ages 11–18) | £18,000–£25,000 | £126,000–£175,000 |
| Day school (ages 4–18) | £14,000–£25,000 | £210,000–£375,000 |
| Boarding senior | £42,000–£65,000 | £294,000–£455,000 |
| Elite boarding (Eton, Harrow etc.) | £55,000–£70,000 | £385,000–£490,000 |
These are in today’s money — fees have historically risen faster than general inflation, and will likely continue to do so.
For a family with two children to pay for, it’s common for total fees from age 7 to 18 to reach £300,000–£500,000 or more.
The VAT Change and Its Impact
From 1 January 2025, private school fees became subject to 20% VAT. The theoretical maximum pass-through to families was 20% on fees. In practice:
- Some schools absorbed part of the cost and raised fees less than 20%
- Most schools raised fees 10–18%
- A minority passed through the full 20%
- Combined with general inflation, some families saw 25–35% fee increases in 2024–25
The change also allowed private schools to claim back VAT on capital expenditure (buildings, equipment) so some schools benefit operationally — though this hasn’t reduced fees.
What Do You Get for the Money?
Academic Outcomes
Private school pupils do achieve better academic results on average:
- Higher A-level grades
- Higher university admission rates
- Significantly higher Oxbridge and Russell Group admission rates
But this is complicated by:
Selection effects: Private schools select or attract higher-ability pupils. Grammar schools and strong state comprehensives produce similar outcomes with similar intake.
Socioeconomic effects: Private school pupils tend to come from higher-income, higher-education households. Research consistently shows parental education is a stronger predictor of child attainment than school type, when selection is properly controlled for.
What’s attributable to the school itself? Contested. The Sutton Trust and academic researchers estimate a relatively modest independent effect of private schooling on attainment, after controlling for pupil and family background.
What private schools do offer clearly:
- Smaller class sizes (average 12–15 vs 25–30 in state schools)
- Greater staffing resources
- Better facilities in many cases
- Wider extracurricular provision
- Networks and connections (particularly for elite boarding schools)
The last point — networks and connections — may be the most honestly important differentiator for some professions (law, finance, politics, media), where private school alumni networks remain disproportionately powerful.
Beyond Academics
Private schools often offer genuine advantages in:
- Sport (more facilities, more coaching, competitive fixtures)
- Arts provision (music, drama, art)
- Specific specialisms (sport, science, arts — especially in specialist independent schools)
- Individual attention for children with particular needs or talents
For some families, the per-child and holistic experience is the genuine motivation — not exam outcomes.
The Opportunity Cost Calculation
Every pound spent on school fees is a pound not invested or saved elsewhere. At current fee levels, this opportunity cost is enormous.
Example: £20,000/year in school fees for one child from age 11 to 18 (7 years). Same amount invested in a global equity ISA at 7% average annual return:
| Period | Invested value (7% return) |
|---|---|
| After 7 years | ~£180,000 |
| After 14 years | ~£440,000 |
| After 21 years | ~£880,000 |
This is money that could fund:
- University and living costs for 2–3 children
- A significant contribution to a first home deposit
- Pension funding that provides £15,000–£20,000/year in retirement
It is honest to say that for most families, not sending to private school and investing the fees would produce a better long-run financial position.
Alternatives Worth Considering
Grammar Schools (Where Available)
In England, there are 163 grammar schools in 36 areas. Entry is via the 11-plus exam. Grammar schools offer:
- State school funding (no fees)
- Academic results comparable to private selective schools
- Oxbridge and Russell Group success rates close to top private schools
Limitations: only available in certain areas, highly competitive entry, tutoring culture may replicate some private school costs.
High-Performing State Academies
Some state academies deliver results that match or beat local private schools. Ofsted data and league tables allow comparison. Worth researching your local area before assuming private school is the only option.
Targeted Private Schooling
Rather than 14 years of fees (ages 4–18), many families choose to send children to private school for only specific stages:
- Sixth form only (ages 16–18) — to boost A-level results and university access
- Senior school only (ages 11–18) — skipping the private prep years
This significantly reduces the total spend while potentially capturing the meaningful networking and academic period.
Can You Afford It?
The Income Requirement
Financial advisers typically suggest spending no more than 15–20% of gross income on any single recurring cost. At £20,000/year per child:
| Number of children | Required income for 15% rule | Required income for 20% rule |
|---|---|---|
| 1 child | £133,000 | £100,000 |
| 2 children | £267,000 | £200,000 |
| 3 children | £400,000 | £300,000 |
For most families these thresholds are out of reach — and that’s before factoring in reduced pension contributions, larger mortgages to afford the right school catchment area, and lifestyle costs.
If you’re stretching to afford it
Many families underestimate the financial stress of fees rising faster than income. Honest questions to ask:
- Can we sustain fees if one of us loses our job for 6 months?
- What happens if we divorce, or become seriously ill?
- Are we making adequate pension contributions? (Fee-paying families often sacrifice pension contributions — which will create a different problem later)
- Do we have 3–6 months’ emergency fund after fees?
Fee Assistance
Many private schools offer bursaries and scholarships. Bursaries are means-tested financial assistance — some schools offer very substantial discounts (up to 100%) for families who apply and qualify. Scholarships are merit-based, typically offering 5–20% off fees.
If you’re interested in a school your income wouldn’t normally support, it’s always worth asking directly about bursary arrangements.
The Honest Verdict
Private school can provide real benefits — but they’re not the guaranteed pathway to success that fees might suggest. The honest answer is:
- For families who can comfortably afford it without sacrificing other financial priorities — it can be worth it for the right child at the right school
- For most families who would need to significantly stretch, sacrifice retirement savings, or take on debt — the financial maths rarely works in their favour
- The best state schools produce outcomes comparable to most private schools for most children
- The opportunity cost is enormous and permanent — money spent on fees is money not compounding for retirement
The decision is ultimately personal and depends on your specific situation, child, and local school options. But it should be made with clear eyes about the financial reality.
