Why DC Pension Performance Data Should Make Every Employer Stop and Think
An independent dataset published by Corporate Adviser has laid bare something the UK defined contribution (DC) pensions market has long needed to confront: a 144-percentage-point gap between the best and worst-performing default funds over the past decade.
Using CAPAdata, an independently compiled dataset, Corporate Adviser tracked 10-year performance for DC master trust default funds to December 2025. The top-performing fund returned 232%. The lowest returned 88%. TPT Retirement Solutions ranked third in that table, generating returns significantly above average for its members.
| Fund | 10-Year Return | Rank | Key Drivers |
|---|---|---|---|
| Top-performing | 232% | 1 | Dynamic diversification; proactive governance; disciplined oversight |
| TPT Retirement Solutions | ~200%+ | 3 | Long-term investment quality; independent trustee governance; consistent decision-making |
| Lowest-performing | 88% | — | Limited diversification; weaker governance discipline; reactive strategy |
CAPAdata shows not just a performance gap, but the governance and strategy differences behind it.
The question the data raises is not simply which fund won. It is why this kind of variance exists at all, and what organizations choosing a workplace pension scheme should be doing about it.
The Numbers Are Harder to Ignore than the Narrative
For years, the dominant story in DC pensions has been one of consolidation and cost. Big is safe. Cheap is efficient. Both are easy to defend in a boardroom or a procurement meeting, and both implicitly assume that scale and low fees are reliable proxies for quality.
But a 144-point performance gap over 10 years is not a story about fees. It is a story about investment strategy, governance discipline, and the quality of the decisions made on behalf of members year after year.
TPT’s Philip Smith puts it plainly:
For a long time, scale and low cost have carried with them the assumption of safety. Big feels credible. Cheap feels efficient. Both are easy to defend. But member outcomes are what matter, and outcomes like these are a reminder that size and price do not, on their own, define value.”
— Philip Smith, DC Director, TPT Retirement Solutions
What Actually Drives Long-Term DC Performance?
Performance data rarely tells you the whole story, but over a 10-year window it begins to reflect something real: the accumulated effect of consistent, well-governed decision-making.
The factors that appear to matter most are harder to reduce to a single headline number. They include the quality of investment strategy- how diversified, dynamic, and forward-looking it is; the strength of trustee governance, whether the people overseeing the scheme are genuinely independent and expert; and the discipline of oversight, the willingness to act when evidence demands it, even when staying put would be the path of least resistance.
None of these things is visible in a charge cap comparison or a market-share league table. They only show up over time, in outcomes.
The Consolidation Debate Needs Better Questions
The UK government has been pushing DC consolidation, encouraging smaller schemes to merge with larger providers, on the basis that scale creates efficiency, which benefits members. That argument has merit in some contexts. But the CAPAdata results invite a more awkward question: if large schemes were systematically delivering better outcomes, would we see a 144-point spread at all?
Australia has been grappling with a similar debate. Research from the Conexus Institute argues that both large and small superannuation funds can succeed if they are well-designed, and warns against pursuing size for its own sake. The same logic applies here.
The right question for any employer, HR director, or benefits manager is not “how big is this scheme?” It is: how well is it run, and what outcomes is it actually delivering for members?
What This Means for Employers Selecting a Workplace Pension
For HR and reward professionals, the CAPAdata findings reinforce the need for due diligence on default fund performance to be a core part of scheme selection, not an afterthought. When employees are automatically enrolled in a default fund, they trust their employer has made a considered choice. A 144-point performance gap over a decade suggests that not all of those choices are equivalent.
That does not mean chasing last year’s top performer. Short-term rankings are noisy and can reflect little more than a well-timed bet on a single asset class. What matters more is evidence of sustained, disciplined investment management over a complete market cycle through periods of volatility, recovery, and everything in between.
It also means asking providers harder questions: How is the default fund constructed? What is the investment philosophy? Who oversees it, and how independent are they? How has it performed net of charges over five and ten years compared with peers?
Scale Is Not a Strategy – Outcomes Are
The CAPAdata analysis is a timely reminder that the market’s focus on consolidation and cost has sometimes crowded out a more fundamental question: are members actually better off?
TPT’s third-place ranking in a 10-year performance table covering the UK’s major DC master trusts reflects an approach built on long-term investment quality and rigorous governance, not just competitive pricing. The result is a fund that has compounded returns materially above the sector average for more than a decade, and a clear illustration that doing things well, consistently, at scale, is possible.
The more the market is required to answer performance questions with real data, rather than brand reputation or asset size, the better the outcomes will be for the millions of UK workers whose retirement security depends on those answers.
