The Operational Cost of Running a Growing MAT

A multi-academy trust that grows from three schools to fifteen rarely does so with a financial process that was actually designed for fifteen. More often, it is still running the process built for three, stretched a little further with every new academy that joins, until a system that once felt perfectly adequate is quietly buckling under the weight of scale nobody planned for at that level of detail.

What Worked for Three Schools Doesn’t Always Work for Fifteen

At a small trust, a central finance officer can often hold most of the picture in their head: which academy is spending against which budget line, which supplier a given school prefers, which purchase needs a governor’s sign-off. That informal knowledge does not scale. By the time a trust has ten or fifteen academies, no single person can reliably hold that picture, and the trust is left choosing between two uncomfortable defaults: centralising every purchasing decision, which slows individual academies down and frustrates headteachers who know their own budget best, or leaving purchasing largely delegated, which is faster locally but leaves the central team reconstructing spend after the fact rather than seeing it as it happens.

The Academy Trust Handbook Just Raised the Bar

This tension is no longer just an operational preference, it is becoming a governance requirement. The Academy Trust Handbook 2026, effective from 1 October 2026, tightens several expectations that bear directly on growing trusts. Procurement obligations move from ‘should’ to ‘must’ in a number of areas, including the use of Department for Education approved deals for energy and supply staffing. Larger trusts will need CFOs who meet new qualification requirements, and any senior appointment above £174,000 will require DfE approval before it can even be advertised (Department for Education, 2026).

Perhaps most significant for growing trusts specifically, multi-academy trusts will now be required to publish a summary statement explaining how funding is distributed across their schools, published alongside the annual accounts. For a trust that has grown quickly, being able to produce that statement accurately depends entirely on whether purchasing and budget data has actually been captured consistently across every academy, not reconstructed from a mix of spreadsheets and email threads after the fact.

Central Control Without Losing Local Judgement

The trusts that manage growth well are rarely the ones that centralise everything. They are the ones that keep the judgement calls, which supplier, which timing, which local priority, with the people closest to each school, while making sure the underlying data, budget codes, approval thresholds, supplier terms, is consistent across every academy from day one. That distinction, between who decides and who can see, is what lets a trust add its sixth, tenth or fifteenth academy without central finance losing its footing each time.

Getting Ready Before 1 October

With the 2026 Handbook’s stricter procurement and transparency requirements now a matter of months away, trusts that are still relying on manual reconciliation across academies have a narrowing window to close that gap. The trusts likely to find the transition hardest are not the smallest ones, but the ones that have grown fastest without ever revisiting whether their original financial processes were built to scale that far.
