State pension alert: Andy Burnham issued triple lock warning as costs hit 'unsustainable' levels

Britain's fiscal watchdog has sounded the alarm over the pension triple lock, warning the policy will heap billions onto public expenditure and could see national debt balloon to approximately 300 per cent of gross domestic product (GDP) by 2075-2076.

The Office for Budget Responsibility's (OBR) stark assessment arrives just days after Andy Burnham signalled his intention to preserve Labour's manifesto pledge on the mechanism.

Should Governments fail to address the mounting pressures, debt levels risk tripling relative to the size of the economy, the OBR cautioned.

The triple lock guarantees that state pension payments increase annually by the highest figure among inflation, wage growth, or a minimum of 2.5 per cent.

Men and women over 66 are currently eligible for the benefit. Speaking last Friday, Mr Burnham declared "it is important that the commitment in the manifesto stands" when questioned about the policy's future.

Labour's 2024 general election manifesto included a pledge to maintain the triple lock arrangement.

As the widely anticipated successor to Prime Minister Keir Starmer, Mr Burnham's remarks suggest the mechanism will remain in place under any future leadership transition within the party.

According to the OBR's baseline projections, state pension expenditure is set to climb from 5 per cent of GDP to roughly 9 per cent by 2075-2076, representing a major contributor to growing fiscal pressures.

The cost of the triple lock has far exceeded initial expectations since its 2012 introduction, driven by volatile inflation and earnings fluctuations.

By 2029-2030, the mechanism will have added approximately £15.5billion annually to pension spending, nearly three times the £5.2billion originally forecast.

Tom Josephs, member of the OBR's Budget Responsibility Committee, said: "It is certainly a substantial pressure on public spending over the longer term and is making a very significant contribution to that upward pressure on spending."

However, the triple lock is not the sole culprit behind the projected debt surge. The OBR highlighted Britain's ageing population as a significant factor, with the pension guarantee accounting for roughly one third of the anticipated increase in spending.

The watchdog urged policymakers to act swiftly to prevent debt from spiralling onto an "unsustainable and ever-rising path".

Its modelling of alternative approaches suggests that linking pension rises solely to earnings growth, rather than the triple lock formula, would ease fiscal pressures by around two per cent of GDP.

Under current projections, debt is expected to rise from approximately 95 per cent of GDP in 2030-2031.

Steven Cameron, pensions director at Aegon, said: "The next Prime Minister, whether or not Andy Burnham, will inherit many pressing challenges, and on that list is the future of the state pensions triple lock."
