UK schools: the giants run on state money, and the standout profit machine bills councils, not parents

Ask who the biggest school businesses in Britain are and most people reach for the famous fee-paying names. The accounts say otherwise. About 2,111 UK school companies publish a full profit-and-loss, booking £36.1bn of combined income — and the top of that ledger is almost entirely academy trusts: charitable companies running dozens of state schools each on government grant, at £150–312M a year. The fee-paying sector everyone argues about — the tier VAT landed on in January 2025 — is the smaller, older tail of this map. And the single most profitable large operator is neither a trust nor a famous boarding school: it is Witherslack Group, a for-profit special-education group making £47M of pre-tax profit schooling children that local authorities can’t place elsewhere. Figures are approximate — verify against a company’s own accounts before relying on any single number.

A surplus is not a profit — the caveat that changes every number

Almost everything at the top of this market is a charity. An academy trust’s income is government grant; a fee-paying school’s income is fees plus donations. Both are run to spend what they receive on education — the bottom line is a surplus, not a profit, and a thin one is the model working as designed.

Two accounting effects distort that bottom line badly, in opposite directions:

• School transfers inflate it. When a school joins a trust, its land, buildings and reserves transfer in and are recognised as income. A trust that absorbed schools during the year can show a 40–90% “margin” that has nothing to do with running schools well. The same applies when two charitable schools merge.
• Pensions and depreciation deflate it. Staff pension movements and depreciation on donated buildings run through the bottom line, which is why most schools in this map report a deficit in any given year without being in trouble.

So this is a market where the margin column cannot be read the way you would read it anywhere else — and where the handful of genuine for-profit operators (special-education groups, private colleges) are playing an entirely different game from the charities around them. We keep those reads separate throughout.

The shape of the market

The core of the market is remarkably uniform: over half of all companies here sit in the £5–25M band — the natural size of a school or small trust. Only about a quarter of that band reports a surplus, and that is not a graveyard signal the way it would be in a commercial sector: schools are funded to break even, and pension and depreciation charges push many just below the line. Surplus rates rise with scale — to 36% at £25–100M and 40% above £100M — because bigger trusts have more room to absorb those charges.

The giants

Read the names, not just the numbers. Of the twelve largest, nine are academy trusts or their parent charities — state-funded operations. One is an exam board. Only two make their money from anyone other than the government: United Church Schools Trust, the fee-paying arm of United Learning, and Witherslack — whose customers are also, ultimately, the state.

Four health warnings on this table. AQA is an exam board that happens to sit in the schools classification — we exclude it from every competitive read below. The two Oasis entities overlap — the charitable trust is the parent of the family that includes the schools arm, so read them together, not as two separate £270M operators — and the charitable trust’s row is a filing year older than its neighbour’s (its latest accounts show £344.5M of income and a £30.6M surplus). Ormiston’s £62M “surplus” is the transfer-and-grant accounting described above, not £62M made from running schools. And the headcount column is whichever average staff measure each operator files most prominently — full-time-equivalent for some (Ormiston, Witherslack), headcount for others — so treat cross-row staff comparisons as approximate.

The genuinely striking row is Witherslack — majority-owned by Abu Dhabi’s Mubadala Capital since its private-equity exit — a fifth of Ormiston’s operating scale, but a real £47M pre-tax profit at a ~23% margin, growing turnover +20% and headcount +10%. Its business is independent special schools and children’s homes for pupils with complex needs, paid for by local-authority placements — demand the state cannot currently meet in-house. On these numbers, special-education provision is the most profitable thing happening anywhere in British schooling.

The margin column is a trap

The table below lists the largest mid-market operators (£5–100M) reporting a surplus of at least 5%. Rank them by that margin and you’d get it exactly backwards: at a charitable trust, anything much above ~20–30% is almost always a school-transfer year — Aletheia Academies Trust’s 92.6% and Lydiate Learning Trust’s 60% are schools and buildings arriving on the books, not operational brilliance. Even Sherborne Schools Group’s 59.9% — a fee-paying name — is best read as the accounting of Sherborne’s schools coming together under one group, not fee economics.

The honest signal is the unglamorous band: trusts holding a 5–15% surplus year after year at four-figure headcount — The Two Counties Trust, The Laurus Trust, Bath & Wells Diocesan Academies Trust, Scholars’ Education Trust, Anglian Learning. In a sector funded to break even, a steady mid-single-digit surplus is the definition of well run.

…and 10 more between £49M and £67M. Rows marked * are margins almost certainly inflated by school transfers or one-off gains — treat as expansion markers, not performance.

Growth, read with care

This is the most growth-tilted market we have mapped — and almost none of it is winning customers. A trust “grows” when schools join it, so the extreme growth rows are the sector’s version of M&A: Christ The Redeemer Catholic Education Trust (+8,853%) is a newly formed trust taking on its founding schools in its first full year, and the +250–450% rows below it are the same event at different stages. The staff column confirms it — headcount arrives with the schools.

The read-through: consolidation into larger trusts is still running hard, a decade and a half after it started. The genuine organic growth story in the whole map remains Witherslack — +20% with profit and hiring behind it, driven by special-needs demand, not by absorbing anyone.

The flattest market we’ve mapped

Education is the least concentrated market on our shelf: the top 5 operators hold just 4% of the £36.1bn, and even the top 100 hold barely 28%. Compare road freight (top 5 = 38%) or temp staffing (31%). The reason is physical: a school serves a catchment, and no brand or balance sheet changes that. Trusts consolidate administration, not demand — which is why the consolidation wave above never produces a dominant operator.

A market with a birthday

The vintage chart is unlike any other sector’s: 1,378 of the 2,111 companies — two-thirds of the map — were incorporated between 2010 and 2015. That is the academisation wave made visible: the policy that turned state schools into standalone charitable companies created most of this market’s population in a five-year burst. The pre-1990 cohort (247 companies) is where the old fee-paying schools live — many carrying incorporation dates a century or more old.

Ownership tells the same story from another angle: barely 1% of these companies carry the Holdings/Bidco/Topco naming that fingerprints a private-equity structure — schools are essentially not a buyout market, because most of them are charities with no owners at all. The 924 individually-owned companies are the small fee-paying and tuition tail. The exception, again, is special education, where for-profit groups like Witherslack operate at real scale.

The VAT year is coming to these accounts

Most of the fee-paying tier’s accounts here predate January 2025, when 20% VAT was applied to private school fees, with charitable business-rates relief withdrawn from that April. That means this map is the before picture: the baseline against which the first full VAT-year accounts — arriving through late 2026 — will show which fee-paying schools absorbed the change, which passed it on, and which shrank. The mid-market independents in the £1–25M bands, without endowments or a group behind them, are where the strain will show first.

What the map shows

1. Britain’s biggest school companies are state-funded. Academy trusts fill the top of the ledger at £150–312M a year — the famous fee-paying names are the map’s old, smaller tail.
2. A surplus is not a profit. Trust “margins” above ~30% are school transfers and one-off gains; steady 5–15% surpluses (Two Counties, Laurus, Bath & Wells) are what well run actually looks like here.
3. The profit engine is special-needs education. Witherslack makes £47M at ~23% margins, growing +20% with hiring behind it, on local-authority placements — the only large-scale, genuinely commercial success in the map.
4. Growth is consolidation, not competition. The extreme growers are trusts absorbing schools; nobody wins a catchment.
5. It is the flattest market we’ve mapped — top 5 = 4% — and two-thirds of it was incorporated in one 2010–15 policy window.
6. The VAT shock isn’t in these numbers yet. The first full VAT-year accounts from the fee-paying tier land through late 2026; this map is the baseline.

Methodology and caveats

This covers only the UK school companies that publish a full profit-and-loss — the 2,111 with usable numbers out of 2,774 active companies in the band; the rest file abridged or dormant accounts. Most operators here are charities: their bottom line is a surplus, routinely distorted upward by school transfers and downward by pension and depreciation charges, and it should never be read as commercial profit. An exam board and overlapping group entities are flagged and excluded from competitive reads. Figures are approximate and business-type labels are directional — verify against a company’s own accounts before relying on any single number. This is analysis, not financial advice.
