Ministers discussed and considered transitional arrangements during the passage on the Pensions Bill 2011. The Government carried out extensive analysis of the impacts of bringing forward the rise to age 66 when legislating for the change in State Pension age. A final Impact Assessment was published in November 2011 following Royal Assent the Pensions Act 2011. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/181461/pensions-bill-2011-summary-of-impacts.pdf The Impact Assessment includes analysis of the decision to amend the timetable originally set out in the bill so as to cap the maximum increase at 18 months rather than 2 years. This concession benefited almost a quarter of a million women, who would otherwise have experienced delays of up to two years. A similar number of men also benefited from a reduced increase, and the concession was worth around £1 billion in total. The Government will not be revisiting the State Pension age arrangements for women affected by the 2011 Act.
