The scrapping of the UK triple lock debate has flared up again, with think tanks, economists and even former ministers pushing for change. The triple lock guarantees the state pension rises every year.
Critics say it’s too costly to keep. Supporters say pensioners can’t afford to lose it. Here’s where things stand, who wants reform, and why Labour is unlikely to act any time soon.
- The triple lock raises the state pension by the highest of inflation, earnings growth or 2.5%.
- The OBR expects it to cost around £15.5bn a year by 2029/30 — triple the original forecast.
- A smoothed earnings link could save £650m a year, one think tank says.
- Labour pledged to keep the triple lock in its 2024 manifesto.
- Polls show far more voters want it kept than scrapped.
What Is The Triple Lock?
Brought back in 2011 under the Conservative government, the triple lock sets how much the state pension rises each year. It goes up by whichever is highest: average earnings, inflation, or 2.5%. The idea was to stop pensions slipping behind wages, as they had for decades.
What’s Fuelling The Scrapping The UK Triple Lock Debate?
Money, mainly. The Office for Budget Responsibility estimates that the cost will reach £15.5bn a year by 2029/30 — three times the original estimate. The Resolution Foundation, once led by current pensions minister Torsten Bell, goes further still.
It calls the measure “a terrible policy” and says a smoothed earnings link could save £650m a year by the end of this parliament. Some £12.6bn could have been saved since 2012, it adds.
The bill keeps climbing. MoneyWeek points out that the state pension is set to cost around £146bn this year — roughly 5% of GDP — up from £86bn in 2005/06. The Intergenerational Foundation says spending has jumped almost 70% in real terms over two decades.
The Institute for Fiscal Studies has called for the lock to go. The Telegraph reports UK national debt could top £3tn within months, with the triple lock a key pressure.

The Alternatives On The Table
Plenty of fixes have been floated. The International Monetary Fund wants a “transparent public debate” and suggests linking pensions to the cost of living.
The Intergenerational Foundation prefers capping rises at inflation until 2030/31, then averaging inflation and earnings — an approach the OECD has backed too.
The boldest idea comes from the Tony Blair Institute for Global Change. It would scrap the state pension altogether and introduce a “Lifespan Fund”. People would build up credit through work and draw on it when needed. Its analysis suggests savings of £19bn a year by 2035/36, rising to £38bn by 2045/46.
Who Wants It Scrapped?
The pressure is broad. Ruth Curtice, chief executive of the Resolution Foundation, branded it “a terribly designed policy” and urged ministers to move quickly.
Scottish Financial News flags that pensioner poverty actually rose 2.3 percentage points in the 12 years after the lock began, having fallen 15.8 percentage points in the 15 years before.
Tom Selby of AJ Bell said the triple lock “will simply have to be scrapped” — the only question is when. Sir Jeremy Hunt, the former chancellor, has warned pensioners might think twice if they realised it was being funded by rising national debt their grandchildren will have to repay.
Why Labour Won’t Budge
The politics are brutal. Around a fifth of the population is of state pension age — a huge chunk of voters. Research from AJ Bell shows 38% of Britons want the triple lock made permanent, against just 6% who’d scrap it. The split is sharply generational: 68% of Baby Boomers back it, versus 14% of Gen Z.
Reform UK pledged in April to keep the lock, just months after Nigel Farage called it “up for debate”. Labour leadership hopeful Andy Burnham told The i Paper that ditching the manifesto promise would be “very damaging”. Royal London’s Jamie Jenkins put it neatly: it’s become a political hot potato.

The Human Side
For many pensioners, this is anything but abstract. Maria Fuccio, 69, from Hampshire, gets the new state pension of £241.30 a week.
A former social worker of 30 years, she still turns to food banks. “It’s a struggle to get by,” she said. On her party of choice, she added, “The whole ethos of Labour was cradle to the grave – not hasten to the grave.”
Dennis Reed of the campaign group Silver Voices fears pensioners are being used “as a scapegoat for the country’s economic problems”. Former pensions minister Steve Webb argues the lock should stay for “at least another couple of Parliaments”.
What Happens Next?
For now, the government is holding firm. The Department for Work and Pensions says supporting pensioners is a priority, and the lock stays for the rest of this parliament — worth up to £2,100 a year extra to millions.
The Treasury adds that 12 million pensioners will gain up to £470 this year, on top of the highest personal allowance in the G7.
A wider review is looming, though. The Pensions Commission is examining future retirement income, and Dr Suzy Morrissey is reviewing state pension ages.
With a general election expected in 2028 or 2029, real change may have to wait. But as the costs mount, this debate isn’t going anywhere.
