“Academy budgets are in an even worse state than those of council-run schools with eight out of 10 in deficit, suggest figures from their accountants.
Two more years like this and the entire sector could face insolvency, says a report from the Kreston UK accountancy network which looked at 450 schools.
It follows data published on Friday which showed over a quarter of council-run secondary schools were in deficit.
The government disputes the findings of both reports.
The 450 schools analysed in the Kreston UK report are all audited by accountancy firms in the network and are a representative sample of academies in England, say the authors.
The figures, for the year ending 31 August 2017, show that of these academies:
55% were in deficit before the effect of depreciation of assets like buildings, equipment and furniture was taken into account
this rose to 80% when the accounts were adjusted to include depreciation.
The report, co-authored by accountants Duncan & Toplis, calls for more money to be put into schools to avoid staff cuts.
Staff make up 72% of costs in these academies, say the authors.
“This means that schools will have little choice other than to cut teacher numbers to reduce financial losses in future.”
The report warns that cutting staff numbers and finding enough money for redundancy payments could accelerate some schools towards insolvency.
Nick Cudmore, report author and director at Duncan & Toplis, said school senior management teams already faced tough decisions.
“Schools are doing everything they can to save as much money as possible; cutting back on staff, replacing experienced teachers with less qualified people and going cap-in-hand to parents, but it still isn’t enough to avoid overspending.”
He said the academies in the report were also delaying repairs and putting off replacing obsolete technology, which he warned could be more expensive in the long run.
“The whole sector will be on the verge of insolvency if they have just two more years like this one.
“Accountants can work with governors to help them save every last penny possibly, but without significant increases in public funding, this could become a full-blown crisis,” he said.
On Friday, research by independent think tank the Educational Policy Institute found the number of council-run secondary schools falling into deficit had trebled to 26.1% in the four years to 2017.”
