UK September Borrowing Figures Due from ONS Today

The Office for National Statistics is scheduled to publish the UK’s public sector finances figures for September today, 20 October 2026. The update will give taxpayers and policymakers a monthly measure of government borrowing; readers should check the ONS bulletin for the actual outturn, its comparison with September 2025 and any revisions. The release calendar confirms the publication date, not the result.

What the September release measures

Public sector net borrowing measures how much more the public sector spends than it receives in a given period, after taking account of certain financial transactions. It is a monthly snapshot of the gap between income and spending, not a direct measure of what an individual household owes or pays in tax.

The figures cover the public sector, including central and local government and public corporations. The ONS bulletin explains the components and any adjustments behind the reported measure. Borrowing is commonly discussed alongside public sector net debt, which measures accumulated liabilities at a point in time; the two figures describe different things.

How to read one month’s figure

A September outturn can help show how public finances are developing, but a single month does not establish the full-year borrowing total or predict a tax decision. Receipts and spending vary during the year, and monthly data may be revised as more information becomes available.

When the bulletin is published, compare September 2026 with September 2025 and note whether the ONS has revised earlier months. A year-on-year comparison adds context, but the wider pattern across several months and the explanations for any change matter too. Borrowing data can inform debate about spending, taxes and the economy; it does not by itself determine what HM Treasury will do. UK borrowing rose amid fiscal pressures, offering broader context for that debate.

Where to check the official result

The ONS release calendar lists the September public sector finances publication for 20 October 2026. The calendar establishes when the release is scheduled, but it does not include the outturn. Check the ONS public sector finances bulletin for the published numbers, comparisons and revisions once it is available.
