The Pensions Commission's interim report, published in 2026 with government backing, sets out a clear and sobering picture of retirement saving in the UK. Around 15 million people are currently under-saving for retirement, a figure that could rise to 19 million without meaningful change to either individual behaviour or the wider system. The full recommendations are expected in 2027, but the evidence already presented carries a straightforward message for anyone thinking about their later years.
Why the gap has grown
Retirement planning in the UK is under pressure from several directions at once. People are living longer, which means retirement income needs to stretch further. Fewer individuals can rely on defined benefit pension schemes, which provided a guaranteed income for earlier generations. Instead, the responsibility for building retirement wealth now falls much more heavily on individuals themselves, through their own contribution decisions, investment choices and, ultimately, how they draw on those savings.
At the same time, around 45% of working-age adults are not contributing to a pension at all, despite many being in employment. For those who are contributing, the Commission warns that the minimum contribution levels required under automatic enrolment may not be adequate to fund a comfortable retirement, particularly for those starting later or earning less over their careers.
Who faces the greatest risk
The Commission identifies three groups as particularly vulnerable to retirement income shortfall.
Low and middle earners represent the largest group at risk. Many rely solely on the legal minimum workplace pension contributions and have limited scope to save additionally from their regular income. The gap between what they are saving and what they are likely to need is often significant.
Self-employed workers face a structural problem. With no employer contributing on their behalf and no automatic enrolment requirement, only around 4% of self-employed people are currently saving into a pension. This group has grown substantially over the past decade and now represents a meaningful portion of the working population.
Women, on average, accumulate lower pension savings than men over the course of their working lives, a consequence of career breaks taken for caring responsibilities and persistent income differences. For women who have taken extended time out of the workforce, the shortfall can be substantial and difficult to recover without a deliberate plan.
The risk of treating minimum contributions as sufficient
One of the Commission's clearer warnings is that being enrolled in a pension and saving at the minimum rate are not the same thing as saving adequately. Automatic enrolment has been a genuinely important development in UK retirement provision, bringing millions of people into workplace saving who had previously opted out. But the minimum contribution rates were designed as a floor, not a destination.
For many savers, particularly those in their forties or later who have not accumulated significant pension wealth, maintaining minimum contributions alone is unlikely to produce the income they would need in retirement to sustain their current lifestyle. The Commission recommends reviewing contributions regularly and increasing them where circumstances allow, rather than treating the enrolled minimum as something close to enough.
How people are accessing their pensions is also a concern
Beyond the accumulation problem, the Commission highlights a growing issue with how pension savings are being drawn down. Current trends show a significant number of individuals withdrawing pension funds at the earliest available opportunity, often using the money for substantial one-off expenditures rather than managing it as a long-term income source.
Pension flexibility introduced in recent years has given individuals far greater control over how and when they access their savings. That flexibility is valuable, but it has transferred a significant amount of financial risk and decision-making responsibility onto individuals who may not have a clear plan for how their pension needs to last. The consequence, for some, is that money set aside for retirement disappears more quickly than expected.
The broader landscape is changing too
The Commission also points to structural shifts that make the challenge more complex than it might have been for previous generations. Home ownership rates are falling, which means more people entering retirement may face ongoing rental costs rather than a paid-off property providing housing security. Slower economic growth has constrained real wage increases and therefore the capacity to save. The State Pension, while valuable, is unlikely to be sufficient on its own for most people to maintain a reasonable standard of living.
Taken together, these factors mean that the retirement landscape facing working-age adults today is materially different from the one their parents navigated, and the strategies that worked for previous generations will not automatically apply to this one.
What individuals can do now
Whilst the Commission's detailed recommendations are still forthcoming, the evidence already in the public domain points clearly to a few core principles that apply to almost everyone.
- Starting early and reviewing contributions regularly makes a compounding difference over time, even if individual increases are modest
- Understanding exactly how much you have saved, across all pension arrangements including older workplace pensions, is a necessary first step before any planning can be meaningful
- A clear view of how your pension sits alongside your other income, property, savings and longer-term goals matters more than managing any one asset in isolation
- Accessing pension funds early, without a plan for sustaining income over a potentially long retirement, carries risks that are not always immediately apparent
- For the self-employed and those with interrupted careers, the default position of doing nothing is unlikely to produce an adequate outcome
The message from the Commission is not a counsel of despair. The UK pension system has made real progress over the past two decades and the foundations are there. But for many people, those foundations need to be built upon deliberately, and the time to act is now rather than closer to retirement when the options narrow.
At Aetas, we work with clients at every stage of their working and retirement lives to build a pension and retirement income strategy that fits their real situation. If you would like to understand where you stand and what your options look like, we are glad to help you think it through.
