The interesting bits

What the filings actually show

Reading every school's accounts side by side surfaces things a single prospectus never would: the dependencies, the outliers, the quiet numbers press releases don't mention. Every finding here links back to the document it came from.

The only maths school outside the state system

Every other specialist maths school is a state-funded 16–19 free school, drawing ESFA/DfE per-student funding. The 1729 Maths School is the sole exception: no GAG, no ESFA grant, no Companies House filing of its own. Instead it runs as a project inside a much larger independent-school charity, underwritten by a single family's stated £30 million commitment over ten years.

A named funding top-up that isn't published anywhere as its own number

KCL Maths School's own accounts describe its DfE funding as "'basic rate' per-student funding and a maths school top-up" — confirming, in an audited primary document, that specialist maths schools get more than the standard national rate. But the two aren't broken out separately anywhere we could find: the accounts, and DfE's public funding-rate documents, only give a combined figure.

Two pre-opening schools, two different silences

Durham and Nottingham were both caught in the same 2024–25 Department for Education review of 44 free-school projects, and both were confirmed to proceed in December 2025. Neither has a maths-school-specific line in its future host trust's accounts yet — Providence Learning Partnership (Durham) and East Midlands Education Trust (Nottingham) both file consolidated accounts that, for now, say nothing about the school that hasn't opened inside them.

A trust-wide surplus can hide a school running a deficit

Cambridge and Leeds are both academies inside larger multi-academy trusts, so neither has accounts of its own — the trust's consolidated total is all Companies House shows. Eastern Learning Alliance, Cambridge Maths School's trust, posted a healthy £231k group surplus for 2024/25. But DfE's own school-level benchmarking data tells a different story for the maths school specifically: an in-year balance of −£151,388 and a reserve that's gone negative, alongside the highest per-pupil teaching-staff spend of any comparable school nationally. Leeds Maths School, under the same consolidation model, ran a small surplus at both trust and school level. Neither picture is visible from the trust accounts alone — only DfE's school-level data separates them.

A single-school trust that became a two-school trust the day before opening

Aston Maths School's trust was incorporated in 2023 under the name "Aston University Mathematics School" — built, it looks like, to run this one school alone. Then, on 14 July 2025, it was renamed Aston University STEM Education Academy Trust, and on 1 September 2025 — the day after its most recent accounting year ended, and the same week the maths school opened its doors — a second, pre-existing academy joined it. Its only Companies House filing so far is two pages of dormant-company accounts. Whenever real figures do appear, they'll describe a merged two-school trust, not this school in isolation.
