HM Treasury has put a date on the next major fiscal event. In a letter published on 31 July 2026, Chancellor John Healey told Treasury Committee chair Dame Meg Hillier that the Budget will be held on 28 October 2026, with the Office for Budget Responsibility asked to prepare an economic and fiscal forecast for the same day.

For readers, that matters less as political theatre and more as planning certainty. The government’s fiscal framework says it intends to hold one major fiscal event each year to give families and businesses clearer tax and spending timetables, so a fixed Budget date helps boards, finance teams and investors mark the point when policy changes are most likely to land.

The OBR element is not a footnote. The watchdog says its forecasts accompany the Budget and fold in the tax and spending measures announced by the Chancellor, while its own forecast process notes that the Chancellor formally commissions a forecast ahead of a fiscal event. In practice, that makes 28 October the next clear point for an official read on the UK’s growth and public finance outlook. (obr.uk)

There is, though, a limit to what can be read into a one-page letter. HM Treasury’s notice confirms timing and repeats the government’s emphasis on fiscal credibility, economic stability and sticking to its fiscal rules, but it does not set out any tax changes, spending totals or sector-by-sector decisions. Readers looking for detail will have to wait for the autumn package itself. (gov.uk)

For SMEs, the practical value lies in the run-up rather than the announcement itself. A confirmed late-October Budget gives owners and finance directors a clear checkpoint for refreshing cash-flow plans, hiring assumptions and capital spending cases before the autumn, especially because Budgets arrive with the OBR’s view of the public finances and the Treasury’s latest tax and spending choices. That planning point is Market Pulse UK’s read of why the date matters; it is not a new measure announced by the Treasury. (obr.uk)

The simple takeaway is that Budget 2026 now has a fixed slot: 28 October. Between now and then, the signals worth watching are official Treasury language, OBR preparation and any pre-Budget consultations or policy hints that narrow the range of options before the Chancellor stands up in Parliament. HM Treasury published the confirmation on 31 July 2026. (gov.uk)
