The UK’s state pension system could face one of its most significant proposed overhauls in decades, following recommendations from the Tony Blair Institute. The plan calls for scrapping existing mechanisms, including pension credit and the triple lock, and replacing them with a more flexible model.
The proposals arrive amid growing concern over the long-term affordability of pension spending, as the number of retirees continues to rise. They set out a vision for a system that reflects changing patterns of work, ageing, and life expectancy.
Proposal Replaces Fixed Retirement with Flexible “Lifespan Fund”
According to the Tony Blair Institute, the current state pension is “outdated, increasingly unaffordable, and too rigid for the way people live and work”. The think tank proposes replacing it with a system known as a Lifespan Fund, which would remove the official retirement age entirely.
Under this model, individuals would build entitlement through National Insurance contributions, as well as periods of caring, study, job-seeking or ill health. Workers would receive half a year of pension entitlement for each year of contributions, up to a maximum of 20 years, requiring around 40 years of contributions in total.
People would be able to choose when to access their pension, rather than waiting until a fixed age. The amount received would vary depending on factors such as contributions, age, health, and life expectancy, in a way similar to annuity calculations.
The proposals also include provisions allowing early access to pension funds during working life, including periods of retraining, unemployment or caring responsibilities. According to Sky News, individuals accessing funds early would later pay higher National Insurance contributions to rebuild their entitlement. The plan would also scrap pension credit, a benefit currently claimed by around 1.4 million people, and remove the triple lock, replacing it with increases linked to median earnings.
Rising Costs and Ageing Population Drive Calls for Reform
The recommendations are framed against projections of rising pension costs and demographic change. According to multiple reports, the number of pensioners is expected to increase from 12.6 million today to nearly 19 million by 2070, placing sustained pressure on public finances. State pension spending reached £146 billion in 2025–26 and is forecast to exceed £172 billion annually by the end of the decade. The Tony Blair Institute estimates its proposed reforms could save around £66 billion a year by 2070.
The triple lock, which guarantees annual increases based on inflation, wage growth or 2.5 per cent, is identified as a key driver of long-term costs. The think tank describes it as a “long-run cost escalator” and recommends its removal after the next election cycle.
Reaction to the proposals has been mixed. According to The Telegraph, former pensions minister Sir Steve Webb raised concerns about linking pension payments to individual health data, describing the approach as complex and intrusive. Others have questioned how such a system would interact with existing welfare and private pension arrangements.
At the same time, political support for the current system remains strong. The government has committed to maintaining the triple lock for the duration of the current parliament, citing the need to provide certainty for pensioners. The debate reflects broader tensions between affordability, fairness, and simplicity, as policymakers consider how to adapt the pension system to future demands.
