The Office for Budget Responsibility will publish its next Economic and fiscal outlook alongside the Budget on 28 October 2026, after the Chancellor has finished presenting to Parliament.
The independent fiscal watchdog confirmed the date in a post on X, with supporting material, supplementary documents and detailed forecast tables all due on the same day. The last OBR forecast before this one was published on 3 March 2026.
The forecast will cover a five-year horizon, assessing the outlook for the UK economy and public finances. It will incorporate the effects of the Chancellor’s policy decisions — the final post-measures forecast that arrives only after the Budget speech ends, meaning the public and Parliament see the independent numbers at the same moment as the full policy picture.
On top of that, the Chancellor confirmed on 31 July 2026 that the Budget would fall on 28 October. Under the Charter for Budget Responsibility, the Chancellor is normally required to give the OBR at least ten weeks’ notice of a fiscal event and formally commission a forecast — a process that includes projections for tax receipts, public spending, public-sector borrowing and public-sector debt.
The OBR typically produces two forecasts a year, usually alongside an Autumn Budget and a Spring Statement. October’s publication will be the second of 2026.
