The State Pension triple lock has helped protect pensioners' incomes for more than 15 years, but new government proposals could change how future increases are calculated.
While the reforms would not take effect until 2030, they raise an important question for anyone planning their retirement. How much should you rely on the State Pension to support your future income?
Introduced in 2010 emergency budget, the triple lock guarantees that the basic and new State Pension will increase each April by whichever is highest of three measures: Consumer Prices Index (CPI) inflation, average earnings growth or 2.5%.
For April 2027, average earnings growth of 3.9% is expected to determine the increase, compared with annual inflation of 3.1% in August 2026.
Prime Minister Andy Burnham has proposed adjusting the triple lock so that future increases would be based on the greater of CPI inflation, 2.5% or the amount needed to keep the State Pension in line with average earnings growth over time.
Although this sounds similar to the existing arrangement, there is an important difference.
Under the current system, the State Pension benefits from whichever measure is highest every year, creating a cumulative effect that can result in payments growing faster than average earnings.
The proposed approach would retain protection against inflation while limiting this longer-term effect.
Research from the Resolution Foundation suggests that, had the proposed system been introduced in 2012, the State Pension would now be 4.5% higher than under a simple earnings link but 5.9% lower than under the existing triple lock.
The immediate impact may be relatively modest, but the cumulative difference could become increasingly significant over time.
Government estimates suggest the reforms could reduce annual State Pension expenditure by around £15 billion by the end of the 2030s, rising to approximately £50 billion a year by 2050.
These savings are intended to help fund the government's proposed National Care Service. However, they would also mean future pensioners receiving less State Pension income than under the existing triple lock.
The proposed reforms are a reminder that retirement planning should not rely solely on assumptions about future government policy.
Although the changes remain proposals, even relatively small adjustments to annual pension increases can have a meaningful impact over a longer retirement.
For those approaching retirement, understanding your expected State Pension entitlement alongside workplace and personal pensions is essential. For younger workers, regularly reviewing pension contributions and other savings can help ensure they remain on track to achieve their retirement goals.
The State Pension will continue to provide an important foundation, but building sufficient personal pension provision remains key to financial security in later life.
