State Pension triple lock reform: A stronger lock needs a clearer key

Why the adjusted triple lock can strengthen confidence in the State Pension
The State Pension triple lock currently increases the basic and new State Pension each year by the highest of inflation, earnings growth or 2.5%. The Government intends to change this from 2029/30.
In brief
The adjusted triple lock is a welcome evolution. It keeps annual protection against inflation and the 2.5% floor, while linking the State Pension back to earnings over time. That should put the system on a more sustainable footing, support fairness across generations and give people greater confidence to plan and save.
The triple lock debate is often framed as a choice: protect today’s pensioners or protect tomorrow’s public finances. That is the wrong choice. A credible State Pension must do both.
The Government’s announcement is therefore welcome. The current triple lock will remain until April 2030. After that, the State Pension will still rise each year by the highest of inflation, 2.5%, or the amount required to return or maintain its value relative to earnings. Read the Government’s triple lock reform factsheet.
From a ratchet to a relationship
The change sounds technical, but the policy intent is simple. The current lock selects the highest of inflation, earnings growth and 2.5% every year. Economic shocks and volatility matter because the current lock selects the highest measure in each individual year. Periods of unusually high inflation or earnings growth can therefore become permanently embedded in the pension baseline, even when long-term averages appear relatively stable. To see how this works, see our triple lock modeller.
The adjusted approach keeps valuable annual protections, but restores a clearer long-term relationship with the wages that support the system.
That matters because sustainability is not the enemy of adequacy. It is what makes adequacy durable. A settlement that pensioners, workers and taxpayers can understand is more likely to command confidence across generations.
Adequacy begins with confidence
This builds on our earlier thinking. In Adequacy begins at State Pension age, we argued that the State Pension is the bedrock of retirement adequacy. In The untapped potential of pensions, we set out how a more sustainable State Pension could sit alongside stronger workplace saving and wider economic reform. The Government’s changes are aligned with this thinking.
People will save voluntarily with more confidence if they understand the foundation they are building on. That means knowing both how much State Pension they might receive, and when they might receive it.
The State Pension age is rising from 66 to 67 between April 2026 and April 2028.
Under current legislation, it is due to rise from 67 to 68 between April 2044 and April 2046.
The third State Pension age review is considering whether the rules and the timetable for age 68 remain appropriate.
A settlement that pensioners, workers and taxpayers can understand is more likely to command confidence across generations.
Explore the future, rather than pretend to predict it
The precise effect of the adjusted lock will depend on the path of inflation and earnings. The mechanism needs unpacking, not another single-number forecast.
Our new State Pension triple lock explorer lets people and policymakers test different assumptions, compare the current and adjusted locks and see how policy choices could affect individual pensions and public spending. It is an educational scenario tool, not a personal forecast or official costing.
Use the explorer to:
- compare the current and adjusted triple locks;
- test different inflation and earnings assumptions;
- explore how volatility affects results; and
- coming soon... examine the relationship between individual State Pension outcomes and public expenditure.
A stronger lock needs a clearer key. Reform can improve sustainability. Understanding can turn that reform into confidence.
