HM Treasury has confirmed that the UK Budget will be held on 28 October 2026, in a GOV.UK publication issued on 31 July 2026. The notice is a timetable update rather than a fiscal statement, but it fixes the date for the government's main autumn tax and spending event. (gov.uk)
The formal route is also significant. The Treasury published the announcement as a letter to the Treasury Select Committee, addressed to Dame Meg Hillier MP. In that letter, the Chancellor said the Office for Budget Responsibility had been asked that day to prepare an economic and fiscal forecast for publication on 28 October 2026, to be released alongside the Budget.

That means the fiscal event and the OBR's official assessment are scheduled to arrive together. For policy professionals, this is the point at which any Budget measures can be read against the same published economic and fiscal baseline. The GOV.UK notice itself does not go beyond confirming the date and the forecast timetable. (gov.uk)
In the letter, the Chancellor frames the autumn Budget against two stated tests: adherence to the government's fiscal rules and retention of a buffer against uncertainty. The text also refers specifically to instability in the Middle East as part of the case for maintaining that buffer. (gov.uk)
The immediate effect of the announcement is procedural clarity. Departments, public bodies, advisers, local authorities and businesses now have a fixed date for autumn planning, including briefing schedules, fiscal monitoring and scenario work ahead of the Budget statement and the accompanying OBR material. This is a narrow update, but one with clear operational value. (gov.uk)
What remains absent is any detail on tax policy, spending decisions or departmental measures. On the published record so far, HM Treasury has confirmed the date and the OBR forecast timetable, and no wider policy package is set out in the notice. The substantive content will therefore be tested on 28 October 2026, when the Budget and forecast are due to be published. (gov.uk)
