English councils spent £144.4bn on services in 2025-26, £5.8bn or 4.2% over their own budgets, according to outturn figures the Ministry of Housing, Communities and Local Government (MHCLG) published on 17 September1. Their non-ringfenced reserves still rose, to £31.1bn from £30.2bn. Schools deficits sit outside those reserves, kept off councils' main accounts by a statutory override that runs to the end of 2027-28.
The per-council returns show where the strain sits. Lowdown's sum of the 292 authorities that filed puts their Dedicated Schools Grant (ring-fenced schools money) deficits, mostly from spending on special educational needs above the grant, at £6.61bn, up 66% in a year2. That is one and a half times the £4.33bn councils hold in reserves not earmarked for anything. In 100 councils the schools deficit exceeds the whole of that free reserve.
Sefton Council on Merseyside shows the sharpest gap in the returns: £3.2m of reserves against a £104m schools deficit in 2025-26, on MHCLG's figures, after drawing £28m during the year3. Hampshire County Council carries the largest deficit, at £346m. The government has promised a grant covering 90% of deficits held at 31 March 2026. If that grant arrives, councils carry about a tenth of the stock, roughly £660m on Lowdown's sum, so their exposure turns on the grant rather than the override date.
Twenty-nine councils on Exceptional Financial Support, which lets a council borrow or sell assets to cover running costs, capitalised £775.7m in 2025-26, on Lowdown's sum of the returns. Capitalising treats running costs as capital spending, so that money never touches the reserves line. Somerset Council will seek further Exceptional Financial Support for 2026-27, Room151 reported on 30 September, and flagged a possible section 114 notice, the formal declaration that a council cannot balance its books, if it does not approve a balanced budget4. Its general reserve stood at £67.4m on 31 March 2026, £6.9m below the 10% benchmark its external reviewer applies5. The County Councils Network, a lobby group for county authorities, projects £7bn of extra annual spending by 20296.
