Retirement plans shift to collective growth model
Collective defined contribution (CDC) pension schemes are gaining traction in the UK. Supporters, including Pensions Minister Torsten Bell, argue these plans could deliver better outcomes for retirees. Critics, however, dismiss the model as little more than “actuarial voodoo.”
The orchard vs. the single tree
CDC shifts the risk and reward of retirement savings from the individual to a collective pool. The difference becomes clear through an analogy: a single fruit tree versus an orchard.
In a traditional defined contribution (DC) pension, each saver tends their own tree. They invest steadily over decades, hoping the tree grows enough fruit to sustain them in retirement. If the tree underperforms, suffers disease, or stops producing too soon, the retiree bears the full loss. Caution often prevails—no one wants to risk killing the tree, even if more aggressive strategies might accelerate growth.
CDC pools savers into a shared orchard. Everyone contributes to the same fund and receives a steady income from a set retirement age, designed to last a lifetime. The orchard’s size and diversity spread risk. If one tree fails, others compensate. New members plant saplings, replenishing the system over time. The large pool allows calculated risks that individual savers might avoid.

The trade-off is clear: no one owns a specific tree. If personal investments would have yielded a bumper crop under DC, the windfall is shared across the collective. If someone dies early, their estate doesn’t inherit the remaining capital—it stays in the pool to support others.
How CDC redistributes risk
CDC redistributes risk rather than eliminating it. Longevity risk, for example, is managed collectively. Payouts are based on average life expectancy, so some receive more than their contributions would have funded, while others receive less. The system ensures no one outlives their income.
Investment risk is also shared. A single market downturn won’t devastate an individual’s savings because the impact is smoothed across the entire pool. This allows the scheme to adopt a more aggressive investment strategy than most DC plans, potentially boosting long-term returns. The drawback is that those returns are shared, not individually owned.
CDC simplifies retirement planning. Savers don’t need to manage complex withdrawal strategies or worry about sequencing risk. The scheme handles investments, payouts, and longevity calculations. For those who’ve watched their DC pots fluctuate with markets, the promise of a steady, lifelong income—even if not guaranteed—offers relief.
Still, drawbacks exist. The lack of inheritance rights may deter some. Others may dislike sharing both risk and reward with strangers. While the model is designed to be self-sustaining, it isn’t immune to systemic shocks. A prolonged market slump or a surge in life expectancy could force benefit cuts.

For now, CDC remains a niche option in the UK. Its backers continue pushing for wider adoption. The orchard analogy suggests the real question isn’t whether it’s flawless, but whether it’s better than relying on a single tree.
A major asset manager advocating for CDC describes it as a middle path. Less box-ticking may be needed for sustainability, but the model isn’t magic. It could offer a better way to manage retirement uncertainties for many. The firm’s materials note that while CDC schemes share risk, they also require trust—in the system and in the actuaries who design it.
The Financial Conduct Authority regulates these schemes. Their long-term viability will depend on real-world performance. Early adopters, like the Royal Mail’s CDC scheme, will serve as test cases. If they succeed, the orchard may become an attractive alternative to the solitary tree.
