CDC Pensions Explained UK: What Collective Defined Contribution Means for You

Most UK workers are in one of two pension camps: defined benefit (DB), where your employer promises a specific income in retirement, or defined contribution (DC), where you build your own pot and hope it's enough. DB schemes are generous but expensive — most are closed to new members. DC schemes are cheap to run but leave you carrying all the risk.

Collective Defined Contribution (CDC) pensions are a third way. They pool everyone's money together, pay a target income for life, and keep employer costs fixed. The UK's first CDC scheme — Royal Mail's — has been running since 2022. A multi-employer version launching in 2027 could make CDC available to millions more workers.

Here's what you need to know.

How CDC Pensions Work

A CDC scheme works like this:

1. Fixed contributions — both you and your employer pay a set percentage of your salary, just like a DC scheme
2. Collective fund — instead of individual pots, all contributions go into one large pooled fund managed by professional trustees
3. Target pension — the scheme calculates a target income for each member based on their contributions and years of service
4. Income for life — when you retire, you receive a regular pension income, similar to a DB scheme

The key difference from DC: you don't manage your own investments or worry about drawdown strategies. The scheme does it for you. The key difference from DB: your pension is a target, not a guarantee. If the fund performs well, your pension could increase. If it underperforms, it could be reduced.

Why Pooling Risk Matters

In a standard DC scheme, your retirement income depends entirely on how your pot performs and when you happen to retire. If markets crash the year before you stop working, tough luck — that's your problem.

CDC spreads this risk across thousands of members at different life stages. Younger members have decades to recover from market dips. Older members benefit from the stability of the larger pool. The result: smoother, more predictable outcomes for everyone.

Research by the Royal Society for the Encouragement of Arts (RSA) and others has suggested CDC schemes could deliver retirement incomes 30–60% higher than equivalent individual DC schemes, primarily because:

• No need for individual de-risking — DC members typically shift to bonds and cash as they approach retirement, sacrificing growth. CDC funds can maintain a growth-oriented strategy across the whole membership
• Longevity pooling — the scheme doesn't need to plan for each person living to 100. It plans for the average, which is more efficient
• Lower costs — bulk investment management is cheaper than millions of individual pots

The Royal Mail Pilot: First Results

Royal Mail launched the UK's first authorised CDC scheme — the Royal Mail Collective Pension Plan — in October 2022, after the Pension Schemes Act 2021 made CDC legally possible.

Here's what we know so far:

• Structure: For each year of service, members build a target pension of 1/80th of their pensionable salary
• Contributions: Both Royal Mail and employees contribute fixed percentages
• First-year results: The 2025 actuarial valuation showed a 6.4% pension increase in the scheme's first full year — above inflation
• Early volatility: The fund did drop 4.6% in its first six months (against a 3.6% benchmark fall), which attracted Telegraph headlines. But that's the nature of a long-term collective fund — short-term dips are expected and smoothed over time

The 6.4% increase is encouraging. It shows the model can work in practice, not just in theory. But one year doesn't make a trend — the real test will be how the scheme handles a sustained downturn.

CDC vs DB vs DC: A Comparison

Feature	Defined Benefit (DB)	Defined Contribution (DC)	CDC
Employer cost	Variable (can be very high)	Fixed	Fixed
Employee risk	Very low	High	Medium
Retirement income	Guaranteed	Depends on pot size	Target (can adjust)
Investment decisions	Trustees	You (or default fund)	Trustees
Income for life?	Yes	Only if you buy an annuity	Yes
Still open to new members?	Rarely	Yes (auto-enrolment)	Growing

CDC sits squarely in the middle. You get more certainty than DC without the crippling cost to employers that killed most DB schemes.

Multi-Employer CDC: Coming in 2027

The Royal Mail scheme is a single-employer arrangement — it only covers Royal Mail workers. The real game-changer is multi-employer CDC, which will let any employer offer CDC pensions through a shared scheme.

The Government published draft regulations in October 2025 enabling multi-employer CDC schemes for unconnected employers. The rules borrow heavily from the existing master trust framework, which should speed up the authorisation process.

TPT Retirement Solutions — which already runs the Social Housing Pension Scheme — is leading the charge. TPT plans to:

• Complete Pensions Regulator authorisation by late 2026
• Launch the UK's first multi-employer CDC scheme in early 2027
• Initially target housing associations and social sector employers
• Eventually open the scheme to a broader range of employers

Other providers are expected to follow. The National Housing Federation has confirmed the TPT scheme should be available to housing associations from April 2027.

What This Means for Workers

If your employer joins a multi-employer CDC scheme, you'd:

• Pay fixed contributions (likely similar to current auto-enrolment rates)
• Build a target pension income based on your contributions and service
• Receive a regular income for life when you retire — no drawdown decisions, no annuity shopping
• Have your pension managed by professional trustees with a long-term investment horizon

You wouldn't need to choose funds, worry about sequencing risk, or figure out sustainable withdrawal rates. The scheme handles all of that.

Who Benefits Most from CDC?

CDC isn't for everyone, but it's particularly attractive for:

Workers who want simplicity. If the idea of managing your own pension investments and drawdown strategy fills you with dread, CDC removes that burden entirely. You contribute, the scheme does the rest.

People who value predictability. A target income for life is more reassuring than watching a DC pot fluctuate and hoping it lasts. Yes, the target can be adjusted — but adjustments in a well-run CDC scheme should be gradual and shared across all members.

Employers replacing closed DB schemes. Many employers shut DB schemes because they couldn't afford the open-ended commitment. CDC gives employees a better deal than pure DC without the DB cost spiral.

Lower and middle earners. Wealthier individuals can afford financial advice and sophisticated drawdown strategies. Workers with smaller pots benefit most from the collective pooling and professional management CDC provides.

Who Might Prefer to Stay in DC?

If you want full control over your investments, enjoy picking funds, and plan to use flexible drawdown in retirement, a standard DC SIPP might suit you better. CDC doesn't offer investment choice or flexible access — it's a managed, collective arrangement.

The Risks

CDC isn't a free lunch. Key risks include:

• Benefits can be cut. If the fund underperforms, your target pension — including pensions already in payment — can be reduced. There's no employer backstop like in DB
• Intergenerational fairness. Getting the balance right between younger and older members is tricky. If the scheme is too generous to early retirees, younger members could lose out
• Limited track record. The UK has exactly one CDC scheme with roughly two years of data. The Netherlands has decades of CDC experience (and has had to cut pensions), but the UK model is still unproven at scale
• No flexible access. You can't take ad-hoc lump sums or vary your income year to year. It's a regular pension, full stop

How CDC Fits Into Your Retirement Plan

Even if CDC becomes widely available, it's unlikely to be your only pension arrangement. Most people will have a combination of:

• State Pension — currently £230.25 per week (full new State Pension 2026/27)
• Workplace DC or CDC pension — from your current employer
• Old workplace pensions — from previous jobs (likely DC or possibly DB)
• Personal pensions or SIPPs — any private arrangements

The question is always the same: will it all add up to enough?

Use the PoundSense Pension Calculator to see how your current pensions, contributions, and State Pension combine into a projected retirement income. Whether you're in a DC scheme now and curious about CDC, or simply want to check if you're on track, getting a clear picture of your numbers is the essential first step.

What to Do Now

CDC pensions aren't available to most workers yet — but they will be soon. Here's what to do in the meantime:

1. Check your current pension. Know what you're contributing, what your employer adds, and what your projected pot looks like. Our pension calculator can help
2. Don't wait for CDC to save more. If you're under-contributing to your current DC scheme, fix that now. CDC will complement existing savings, not replace them
3. Watch for employer announcements. If you work in social housing, education, or the charity sector, your employer may be among the first to offer CDC through TPT
4. Understand your options. If CDC does become available through your employer, compare the target pension with what your current DC arrangement is projected to deliver

The UK pension system has been stuck in a DB-is-dead, DC-is-all-we've-got rut for years. CDC offers a genuine third path — not perfect, but potentially much better than leaving millions of workers to navigate retirement income alone. The next 18 months will tell us whether it lives up to the promise.
