The Treasury has confirmed the state pension age will be raised to 68 by 2039

The Labour Government's proposed plan to increase the state pension age has been slammed as millions of Britons likely to be impacted are "struggling to make ends meet".

Earlier this week, the Treasury confirmed the official retirement age at which someone can begin claiming payments will be raised to 68 by 2039.

Economists note that ministers are speeding up the timeline for state pension age increases, with the legislated increase in the Pensions Act 2007 set to take effect between 2044 and 2046.

However, critics cite the growing unaffordability of the triple lock and Britain's ageing population as a reason to bring this date forward to ease the financial burden placed on working-age taxpayers.

Catherine Foot, who leads the Standard Life Centre for the Future of Retirement, has voiced concerns following reports suggesting the Government may speed up planned rises to the state pension age.

The retirement expert highlighted the delicate position ministers find themselves in, attempting to maintain an affordable pension system as life expectancy increases whilst simultaneously ensuring it remains both fair and sufficient for those who depend upon it."

Ms Foot said: "The state pension remains a critical element of retirement incomes in the UK for millions of people," describing the situation as "a difficult balancing act" for the Government.

Standard Life Centre's modelling indicates that 44 per cent of defined contribution pension savers who may be affected by a rise in the state pension age to 68 are already falling short of their retirement expectations.

More than a quarter of people directly impacted by state pension age increases report daily financial struggles, compared with just one in seven among those already receiving their state pension.

Additionally, around 14 per cent of affected individuals doubt their ability to continue working until their intended retirement date and possess limited private savings as a safety net.

According to the research, lower earners are twice as likely as their higher-paid counterparts to anticipate substantial consequences for their household budgets.

More than a third of people in their early sixties now expect they will have to extend their working lives as a direct consequence of the changes.

Based on research, Generation X workers face particular vulnerability should these changes proceed, as they would be the first cohort directly affected.

Analysts highlight that this generation finds itself in an unfortunate position, having benefited fully from neither the traditional defined benefit schemes nor the newer defined contribution arrangements.

Consequently, many Gen X workers are on course for a decline in their standard of living once they stop working. Ms Foot noted that an official state pension age review is currently taking place, cautioning against treating recent reports as definitive outcomes.

She predicted the debate around balancing pension fairness with fiscal sustainability would intensify over the coming months.
