The state pension triple lock – long seen as untouchable – is facing mounting pressure
The state pension triple lock – long considered politically untouchable – is now under increasing scrutiny as defence concerns and mounting pressure on public finances prompt a fundamental reassessment among senior politicians.
In a remarkable development, prominent figures from across the political spectrum are now openly questioning whether the country can continue to afford the policy. Former Conservative chancellor Sir Jeremy Hunt and veteran Labour figure Baroness Harman have both challenged the consensus, suggesting the arrangement may no longer be financially viable.
Sir Jeremy cautioned that pensioners might reconsider their position if they understood the burden being placed on younger generations, while Baroness Harman proposed means-testing the system to help fund defence spending.
The triple lock ensures pensions increase annually by whichever is highest: inflation, wage growth, or 2.5%. For many years, challenging it was considered political suicide. However, MPs from all parties are now indicating that attitudes are beginning to change.
Labour MP Graeme Downie stated there is “an appetite in all parties” to re-examine the policy, noting that if welfare funding is redirected towards defence “there are no sacred cows”.
Pension increases outpace workers’ earnings
The scale of growth has been dramatic. Since 2010, the state pension for a Brit has climbed from £423 monthly to £1,048 – an increase of nearly 150%. During the same timeframe, average earnings have grown by just 66%, while 55% inflation has eroded most real-terms gains for working people.
Expenditure on pensioners has also soared – from 3.3% of GDP in the mid-1980s to a forecast 5.4% by the early 2030s. The triple lock has played a key role in that rise, alongside an ageing population.
Economists warn the policy is increasingly difficult to sustain. Sir Charles Bean, former deputy governor of the Bank of England, said: “It’s a terrible policy… that is unsustainable.”
Defence pressures intensify
The discussion has intensified amid rising global tensions and demands to increase military expenditure. Britain presently allocates 2.4% of GDP towards defence, though NATO members have committed to increasing this to 3.5% by 2035. Such a move would necessitate an additional £40bn annually – exceeding the combined budgets of the Home Office and Ministry of Justice.
Simultaneously, welfare expenditure continues to climb. Projections indicate it will increase from 10.7% of GDP at the beginning of this Parliament to 11.2% within the coming decade – equating to £406.9bn. Within that total, pensioner benefits alone are forecast to reach £196bn, representing a £45bn increase over merely six years. Former NATO chief Lord Robertson warned: “We cannot defend Britain with an ever-expanding welfare budget.”
Costs far higher than expected
Upon its introduction in 2010, the triple lock was projected to cost £5.2bn annually by the late 2020s. That estimate has since swelled to £15.5bn owing to inflationary pressures and robust wage increases.
Pensioners have benefited repeatedly:
- 10.1% rise in 2023
- 8.5% rise in 2024
With emerging inflation threats connected to geopolitical instability, expenditure could escalate further.
Popular but under scrutiny
Notwithstanding the escalating expense, the measure retains widespread public backing. Surveys suggest approximately 66% of voters favour maintaining it, while just 11% want it scrapped.
However, critics contend such backing overlooks the financial burden. Sir Charles suggested voters “always like having money spent on them if there’s no price tag attached”.
Evolving landscape of pensioner poverty
Advocates maintain the triple lock was necessary to reverse decades of deterioration. Yet specialists indicate the issue it aimed to address has substantially diminished.
Pensioner incomes currently stand at approximately 84% of the population average before housing costs – an increase of 11 percentage points since 2000.
Poverty amongst pensioners has dropped to roughly 15%, down from over 25% in the 1990s. By comparison, children and working-age households are now more prone to experiencing poverty.
Growing calls for reform
Behind closed doors, there is increasing acknowledgement in Westminster that change may be unavoidable. Nevertheless, both Labour and the Conservatives remain publicly committed to the triple lock for the time being.
Chancellor Rachel Reeves has maintained that manifesto commitments will be upheld, while shadow chancellor Sir Mel Stride stated the Tories are “fully committed”.
What might succeed it?
Specialists propose the triple lock could be substituted with a more straightforward system:
- Tying pensions to earnings
- Or merging earnings with inflation protection
One calculation suggests this could save approximately 0.5% of GDP – roughly £15bn annually.
