The triple lock ensures State Pensions rise annually by the highest of wage earnings, inflation or 2.5%. Andy Burnham, Prime Minister, intends to shorten the policy to a double lock, rewarding pensioners annually by the higher of inflation or 2.5%, with a 'new' earnings link in place to guarantee the State Pension holds relative to wage earnings over time. The announcement has caused a divide as Conservatives and Reform have criticised the Labour Party's commitment, reinstating their support for the triple lock. However, as I shall demonstrate, reforming the triple lock will lead to a more financially sustainable Britain, and the right step towards rebalancing the intergenerational disparity between the young and old.

Why Is Andy Burnham Scrapping the Triple Lock?

The Labour Party has struggled to grapple with the triple guarantee, intensifying the pressures on public finances. This assertion is supported by a report from the Office for Budget Responsibility (OBR) that the triple lock will cost £15.5 billion (more than if compared to solely wage earnings) annually from 2029-30, shattering initial forecasts of a mere £5.2 billion. The spiralling cost can be partially attributed to the double-counting effect. This denotes a period of high inflation, which in turn pushes up wage earnings the following year, thereby creating an additional boost for pensioners. This was evidenced by Russia's invasion of Ukraine, which spiked energy prices and, in turn, caused inflation to skyrocket to 10.1% in 2023. This created an unhealthy knock-on effect, as pensioners benefited from an 8.4% wage earnings increase in 2024. This shows a 'fundamental flaw' in the premise of the triple lock, as it creates inequitable gains for pensioners while public finances bear the burden.

The premise of the triple lock becomes increasingly absurd when you consider that Britain is experiencing an ageing population coupled with fewer taxpayers. The number of pensioners per 1,000 working people is estimated to reach 393 by 2070, which equates to almost two working adults per pensioner, which, in turn, creates an unsustainable economy. Moreover, the OBR measured the net fiscal contributions of different age groups, which, in layman's terms, means the average spending per person deducted from tax revenues paid per person. The younger demographic of 30–39-year-olds is anticipated to contribute £19,300 in the tax year 2028-29. By contrast, 70–79-year-olds are set to accumulate a deficit of £20,600. This demonstrates that younger people are tied to the system, contributing to taxes each year, yet as their numbers diminish, more of the population will consist of pensioners, and, as such, these figures are only going to worsen. In short, the government cannot cope with the level of funding needed to subsidise a triple lock in the medium or long term.

The triple lock's uncertainty also restricts future budgeting plans. Over the next 50 years, State Pension would cost the government £80 billion, with a £40 billion swing either way. At the extreme, this is the equivalent of accounting for 6.3% or 9.1% of GDP by the early 2070s, depending on whether volatility reverts to pre-2010 or post-2010 levels, a supposition which is impossible to make. The volatility heightens when you consider that wage earnings growth is only measured between May and July. This was significant during the COVID period, when earnings growth dramatically fell to -1% in 2020, followed by an inflated spike to 8.3% in 2021. A combination of the Job Retention Scheme (which supported employers by subsidising the wages of workers) reaching its peak during this period, and activity and travel being constrained, largely explains the unprecedented fall-then-rise.

The triple lock also intensifies the struggles of young people and families. This is because the policy is a significant contributor to the benefits bill. As such, working-age families are forced to preponderantly bear the burden of benefit cuts. For example, the child benefit, an allowance to support families with children, has been unfairly neglected 'in seven of the last 15 years since the introduction of the triple lock'. This crowding-out effect has resulted in working-age families amassing a deficit of £1,400 for the net impact of changes in benefits between 2010 and 2024. This is frighteningly incomparable with pensioners, who boast a surplus of £900 above inflation. This demonstrates the frailties of the triple lock, as working-age families are being undermined in the benefits bill, with disproportionate gains to favour pensioners. Therefore, continuing to finance the triple lock will only exacerbate this trend, creating more intergenerational disparity.

The Backlash to the Decision: Is It Fair?

Despite overwhelming evidence that the triple lock is a liability on Britain's finances, there remain groups who condemn the actions of the Labour Party. Sharon Graham, general secretary of the Unite trade union, was at the forefront of these criticisms, labelling the decision "morally wrong" because it impacts the "poorest in society". This argument is nonsensical, as pensioners are now the least likely group to go into poverty.

Graham's perspective is backed by Nigel Farage, leader of Reform UK, who was appalled, concluding that Burnham has now abdicated his responsibility to pensioners. Farage has no right to weigh in on Burnham's decision as he himself has previously hinted at reforming the triple lock, arguing that it was "open for debate". Hollinrake, Conservative and Unionist Party chairman, added that hard-working citizens should be rewarded with a "decent standard of earnings in their retirement". This, however, fails to consider the optimal point at which pensioners receive a suitable income as a share of median full-time earnings, while remaining sustainable for the economy. The Pensions Commission, a UK government body, valued this figure at 31%, and Paul Johnson, former Director of the Institute for Fiscal Studies (IFS), a leading London-based think tank, proposed it reach a third. The State Pension is approximately 30% as a share of median full-time earnings. Therefore, Burnham has not abandoned pensioners but rather identified this as the point where they are benefiting, yet not at the expense of public finances.

Britons face worrying realities as the triple lock reform is not expected to subsidise a National Care Service. The Department for Work and Pensions (DWP) has estimated that the double lock will save £11 billion a year by 2040. However, funding a National Care Service may need up to £18.5 billion a year. The widespread political opinion is that tax increases will be used in conjunction with the double lock. Kemi Badenoch, leader of the Conservative and Unionist Party, believes this inevitability, adding that the policy "was falling apart under scrutiny". The obvious point is that tax increases have a cataclysmic effect on whoever they target; however, it is imperative to note that even if these tax measures successfully finance a National Care Service, the Labour Party's political standing will suffer because it will demonstrate its incapacity to reduce public spending. Given the circumstances Britain finds itself in — public debt spiralling out of control and borrowing costs worsening — the government should be concerned with running a day-to-day surplus. Concisely, the double lock and taxes funding a National Care Service mark a failure to solve these compounding issues.

Alternatives to the Double Lock

The Intergenerational Foundation, a London-based think tank, believe the Labour Party should have capped the annual State Pension increases at inflation until 2031, then raised it by the average of inflation and wage earnings from 2031 onwards. This approach was estimated to save the government £19 billion a year by 2035/36 and £38 billion a year by 2045/46. Besides the cost-related benefits, the reform would have limited volatility while maintaining a positive correlation between pensioners and living standards. The idea was backed by the Organisation for Economic Cooperation and Development (OECD), a Paris-based think tank, which had foreseen the adjustment generating long-term savings worth two per cent of Gross Domestic Product (GDP). The Intergenerational Foundation hoped the savings would be redistributed to poorer pensioners 'through the new Low-Income Pension supplement', adding £30 a week, which is equivalent to £1,560 a year. The overarching argument is rational; however, it collapses when opting to reallocate savings, as Britain must focus on reducing the severe public debt we are drowning in.

A 'smoothed' earnings link marked another replacement for the triple lock. Economic projections have modelled the policy from 2027-28 to the end of the UK general election, estimating that it will save £650 million. The conditions of this policy are similar to those of the double lock, whereby the State Pension will rise to meet prices at times when they outpace earnings growth; yet, during periods of higher earnings growth, the State Pension doesn't immediately rise to meet earnings growth and only does so once the threshold of wage earnings is met. The key difference comes with the absence of an arbitrary minimum 2.5% annual increase. This futile 2.5% will yield a higher state pension expenditure for many years, particularly in times of lower inflation. It would be reasonable to assume that the damage created by an additional expenditure bill is offset by pensioners being better off; however, the 2.5% increase is hopeless in protecting State Pensions against either inflation or the threshold of medium full-time earnings. The opinion of Kate Smith, Head of public affairs at Aegon, is that a smoothed earnings link will contribute to reducing volatility, making costs more foreseeable.

Conclusion

The triple lock has had cataclysmic effects upon Britain's public finances, but Burnham's Labour Party's delayed, yet necessary promise requires time to bear fruit. The triple lock's unsustainability likely swayed the government's decision, given it would be untenable to favour pensioners over working adults to the extent that they receive double boosts in their living standards. Not to mention, an ageing population and fewer taxpayers only exacerbate the issues in Britain. Importantly, choosing to reform the policy with a smoothed earnings link would have been a less costly commitment for the government, although the differences are marginal between this and the double lock. The greater emphasis must be placed on the Conservatives and Reform, two parties desperate for political favouritism. For the sake of future Britons, both parties must surrender their attachments to the triple lock come the UK general election, ensuring financially healthier and more prosperous times.
