What happened

Key facts

  • The Office for National Statistics reported that consumer price inflation rose from 3.1% in August to 3.5% in September, above economists’ 3.4% expectation (per finance-monthly.com).
  • Higher motor fuel prices were a major driver of September’s inflation increase (per finance-monthly.com).
  • Public sector borrowing reached £24.5 billion in September (per finance-monthly.com, The Guardian).
  • September borrowing was £1.8 billion above the amount a year earlier and £1.9 billion above the Office for Budget Responsibility’s forecast (per finance-monthly.com).
  • Debt interest payments were approximately £10.9 billion in September, a record for that month, partly reflecting inflation-linked government bonds (per finance-monthly.com).

The brief

UK consumer price inflation rose to 3.5% in September, while public sector borrowing reached £24.5 billion, according to figures reported by the Office for National Statistics. Finance Monthly said inflation had been 3.1% in August and that September’s figure exceeded economists’ 3.4% expectation.

Reuters also reported the 3.5% rate and described it as the highest in nearly a year. Higher motor fuel prices were a major driver of the inflation increase, Finance Monthly reported. The outlet said the rise came ahead of John Healey’s first Budget, due on 28 October.

Global Banking & Finance Review’s headline also linked rising inflation and borrowing with Healey’s upcoming Budget; The Guardian’s headline specifically connected the borrowing figure with his preparations for it. Public sector borrowing totalled £24.5 billion in September.

Finance Monthly reported that this was £1.8 billion more than a year earlier and £1.9 billion above the Office for Budget Responsibility’s forecast. The Guardian’s headline highlighted the £24.5 billion total, while the Financial Times headline said inflation and borrowing had topped forecasts and characterized the figures as a blow to Healey.

Debt interest payments were approximately £10.9 billion for September, a record for that month, Finance Monthly reported. The outlet said inflation-linked government bonds partly accounted for the amount.

It also reported a provisional estimate that public sector debt had exceeded £3 trillion for the first time, while debt measured as a share of GDP was lower than a year earlier. Finance Monthly said the inflation figure was above the Bank of England’s 2% target and that policymakers could raise interest rates at their next meeting on 5 November.

That was presented as a possibility, not as a decision already made. The article tied the potential rate move to the inflation figures. The figures place the upcoming Budget alongside above-forecast borrowing and an inflation rate higher than economists had expected.

Finance Monthly said the borrowing total exceeded the Office for Budget Responsibility’s forecast; its account also identified the motor-fuel contribution to inflation and the record September debt-interest bill. The outlet’s account said Healey was due to deliver the Budget on 28 October, before the Bank of England’s next meeting on 5 November.

Why it matters

  • UK households face the reported rise in consumer price inflation to 3.5%; Finance Monthly identified higher motor fuel prices as a major driver.
  • Public finances recorded £24.5 billion in September borrowing, £1.9 billion above the Office for Budget Responsibility’s forecast.
  • Debt interest payments reached approximately £10.9 billion, a record for September, partly reflecting inflation-linked government bonds.
  • The provisional debt estimate exceeded £3 trillion for the first time, although debt as a share of GDP was lower than a year earlier.

What to watch next

  • Whether John Healey delivers his first Budget on 28 October, as scheduled in Finance Monthly’s account.
  • Whether the Bank of England raises interest rates at its next meeting on 5 November; Finance Monthly said a rise was possible.
  • Whether subsequent public debt figures confirm the provisional estimate that debt exceeded £3 trillion.

How we got here

In August 2026, UK consumer-price inflation was 3.1%, the month-before reading against which the September figure was measured. For public borrowing, the Office for Budget Responsibility (OBR) provides a recurring benchmark: the independent fiscal watchdog publishes forecasts alongside the government’s fiscal plans and later compares outcomes with them.

The framework dates to the Budget Responsibility and National Audit Act 2011, which established the OBR and required it to assess the public finances and the government’s progress against fiscal targets.
