Multiple reports say the UK Treasury has informed the Office for Budget Responsibility (OBR) that the state pension age will rise to 68. The change is described as occurring between 2037 and 2039, depending on the cohort timing. The articles refer to the Treasury’s submission or briefing to the OBR as the basis for the updated timetable. One report also states that the age increase “will be brought forward,” indicating the change could occur earlier than previously expected, though the specifics of what was earlier versus current expectations are not detailed in the provided text. The information is presented as part of government forecasting and planning for pension policy and long-term public finance projections. Overall, the sources agree on the central point: the pension age threshold is set to reach 68 within the 2037–2039 period, as communicated by the Treasury to the OBR, potentially affecting when millions of people become eligible for the state pension. No additional policy details, eligibility rules, or individual impacts are included in the excerpts.
